We intendsuch forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in the Private Securities Litigation ReformAct of 1995 and include this statement for purposes of complying with these safe harbor provisions.

In particular, statements pertaining to our capital resources, portfolio performance, financial condition and results of operations contain certain forward-looking statements. Likewise, all of our statements regarding anticipated growth in our funds from operations and anticipated market conditions, demographicsand results of operations are forward-looking statements. You can identify forward-looking statements by the use of forward-looking terminology such as"believes," "expects," "may," "will," "should," "seeks," "approximately," "intends," "plans," "estimates" or "anticipates" or the negative of these words andphrases or similar words or phrases that are predictions of or indicate future events or trends and that do not relate solely to historical matters. You can alsoidentify forward-looking statements by discussions of strategy, plans or intentions.

Forward-looking statements involve numerous risks and uncertainties and you should not rely on them as predictions of future events. Forward-lookingstatements depend on assumptions, data or methods that may be incorrect or imprecise and we may not be able to realize them. Should one or more of these risksor uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those anticipated, estimated or projected.

The following factors, among others, could cause actual results and future events to differ materially from those set forth or contemplated in the forward-looking statements:

• loss of key customers;

• economic downturn, natural disaster or oversupply of data centers in the limited geographic areas that we serve;

• risks related to the development of our properties and our ability to successfully lease those properties;

• weakening in the fundamentals for data center real estate, including but not limited to, decreases in or slowed growth of global data, e-commerceand demand for outsourcing of data storage and cloud-based applications;

• loss of access to key third-party service providers and suppliers;

• risks of loss of power or cooling which may interrupt our services to our customers;

Table of Contents

• risks associated with real estate assets and the industry;

• failure to maintain our status as a REIT or to comply with the highly technical and complex REIT provisions of the Internal Revenue Code of1986, as amended (the "Code");

• REIT distribution requirements could adversely affect our ability to execute our business plan;

• insufficient cash available for distribution to stockholders;

• future offerings of debt may adversely affect the market price of our common stock;

• increases in market interest rates will increase our borrowing costs and may drive potential investors to seek higher dividend yields and reducedemand for our common stock;

• market price and volume of stock could be volatile;

• international activities, including those now conducted as a result of the recently completed Zenium acquisition and land acquisitions, are subjectto special risks different from those faced by us in the United States;

• the uncertainty surrounding the United Kingdom's decision to withdraw from the European Union and around the British Parliament's approval ofthe agreement with the European Union regarding the United Kingdom's withdrawal from the European Union;

• expanded and widened price increases in certain selective materials for data center development capital expenditures due to international tradenegotiations;

• any failure to comply with anti-corruption laws and regulations could have adverse effects on our business;

• legislative or other actions relating to taxes could have a negative effect on us; and

• other factors affecting the real estate and technology industries generally.

While forward-looking statements reflect our good faith beliefs, they are not guarantees of future performance. We disclaim any obligation other than asrequired by law to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors or for new information, dataor methods, future events or other changes.

The holders of a majority in principal amount of the outstanding debt securities of an affected series may waive any default or event of default with respectto the series and its consequences, except that defaults or events of default regarding payment of principal, premium, if any, or interest, require the consent ofeach holder affected by such waiver.

The holders of at least a majority in principal amount of the outstanding debt securities of any series may direct the time, method and place of conductingany proceeding for any remedy available to the trustee or exercising any trust or power conferred on the trustee. However, the trustee may refuse to follow anydirection that conflicts with law or the applicable indenture, that may involve the trustee in personal liability, or that the trustee determines in good faith may beunduly prejudicial to the rights of holders not joining in the giving of such direction and may take any other action it deems proper that is not inconsistent withany such direction received from holders of the applicable series of debt securities.

The following summary of the terms of the common stock of our company does not purport to be complete and is subject to and qualified in its entirety byreference to the Maryland General Corporation Law (the "MGCL") and our charter and bylaws. Copies of our charter and bylaws have been filed with the SECand are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See "Where You Can Find More Information."

Our charter provides that we may issue up to 500,000,000 shares of common stock, $0.01 par value per share. Our charter authorizes our board of directors,without stockholder approval, to amend our charter to increase or decrease the aggregate number of shares of stock that we are authorized to issue or the numberof authorized shares of any class or series of stock.

As of April 25, 2019, there were 113,172,973 shares of our common stock issued and outstanding. Under Maryland law, our stockholders generally are notliable for our debts or obligations solely as a result of their status as stockholders.

All shares of our common stock offered hereby will be duly authorized, fully paid and nonassessable. Subject to the preferential rights, if any, of holders ofany other class or series of our stock and to the provisions of our charter relating to the restrictions on ownership and transfer of our stock, holders of ourcommon stock are entitled to receive distributions when authorized by our board of directors and declared by us out of assets legally available for distribution toour stockholders and are entitled to share ratably in our assets legally available for distribution to our stockholders in the event of our liquidation, dissolution orwinding up after payment of or adequate provision for all of our known debts and liabilities.

Subject to the provisions of our charter regarding the restrictions on ownership and transfer of our stock and except as may be otherwise specified in theterms of any class or series of common stock, each outstanding share of common stock entitles the holder to one vote on all matters submitted to a vote ofstockholders, including the election of directors, and, except as may be provided with respect to any other class or series of our stock, the holders of shares of ourcommon stock possess the exclusive voting power. There is no cumulative voting in the election of directors. Consequently, the holders of a majority of theoutstanding shares of our common stock can elect all of the directors then standing for election, and the holders of the remaining shares will not be able to electany directors. Directors are elected by a plurality of all of the votes cast in the election of directors.

Holders of shares of our common stock have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptiverights to subscribe for any securities of our company. Subject to the provisions of our charter regarding the restrictions on ownership and transfer of our stock,shares of our common stock have equal distribution, liquidation and other rights.

Under the MGCL, a Maryland corporation generally cannot dissolve, amend its charter, merge or consolidate with, or convert to, another entity, sell all orsubstantially all of its assets or engage in a statutory share exchange unless the action is advised by the board of directors and approved by the affirmative vote ofstockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter, unless a lesser percentage (but not less than a majority of all of thevotes entitled to be cast on the matter) is specified in the corporation's charter. Our charter provides that these actions must be approved by a majority of all of thevotes entitled to be cast on the matter.

Maryland law also permits a corporation to transfer all or substantially all of its assets without the approval of its stockholders to an entity owned, directly orindirectly, by the corporation. Because our operating assets are held by our operating partnership's subsidiaries, these subsidiaries may be able to merge ortransfer all or substantially all of their assets without the approval of our stockholders.

Power to Increase or Decrease Authorized Shares of Common Stock, Reclassify Unissued Shares of Common Stock and Issue Additional Shares ofCommon Stock

Our charter authorizes our board of directors, with the approval of a majority of the entire board and without stockholder approval, to amend our charter toincrease or decrease the aggregate number of shares of stock or the number of shares of any class or series of stock that we are authorized to issue. In addition,our charter authorizes our board of directors to authorize the issuance from time to time of shares of our common stock.

Our charter also authorizes our board of directors to classify and reclassify any unissued shares of our common stock into other classes or series of stock,including one or more classes or series of stock that have priority over our common stock with respect to voting rights, distributions or upon liquidation, andauthorize us to issue the newly classified shares. Prior to the issuance of shares of each new class or series of stock, our board of directors is required byMaryland law and by our charter to set, subject to the provisions of our charter regarding the restrictions on ownership and transfer of our stock, the preferences,conversion and other rights, voting powers, restrictions, limitations as to distributions, qualifications and terms and conditions of redemption for each class orseries. Therefore, although our board of directors does not currently intend to do so, it could authorize the issuance of shares of common stock with terms andconditions that could have the effect of delaying, deferring or preventing a change in control or other transaction that might involve a premium price for shares ofour common stock or otherwise be in the best interests of our stockholders.

We believe that the power of our board of directors to approve amendments to our charter to increase or decrease the number of authorized shares of stock,to authorize us to issue additional authorized but unissued shares of common stock and to classify or reclassify unissued shares of common stock and thereafterto authorize us to issue such classified or reclassified shares of stock provides us with increased flexibility in structuring possible future financings andacquisitions and in meeting other needs that might arise.

RESTRICTIONS ON OWNERSHIP AND TRANSFER

The following summary with respect to restrictions on ownership and transfer of our stock (including warrants and rights to acquire our stock) sets forthcertain general terms and provisions of our charter to which any prospectus supplement may relate. For purposes of this summary, references to "tenants" meanthose persons who are referred to as "customers" elsewhere in this prospectus. This summary does not purport to be complete and is subject to and qualified inits entirety by reference to our charter, including any articles supplementary relating to any issuance of preferred stock pursuant to this prospectus. A copy of ourcharter has been filed with the SEC and is incorporated by reference as an exhibit to the registration statement of which this prospectus is a part. Anyamendment or supplement to our charter relating to an issuance of securities pursuant to this prospectus shall be filed with the SEC and shall be filed orincorporated by reference as an exhibit to the applicable prospectus supplement. See "Where You Can Find More Information."

In order for us to qualify as a REIT under the Code, shares of our stock must be owned by 100 or more persons during at least 335 days of a taxable year of12 months (other than the first year for which an election to qualify as a REIT has been made) or during a proportionate part of a shorter taxable year. Also, notmore than 50% of the value of the outstanding shares of our stock may be owned, directly or indirectly, by five or fewer individuals (as defined in the Code toinclude certain entities such as private foundations) during the last half of a taxable year (other than the first year for which an election to be a REIT has beenmade). To qualify as a REIT, we must satisfy other requirements as well. See "U.S. Federal Income Tax Considerations—Requirements for Qualification—General."

Our charter contains restrictions on the ownership and transfer of our stock. Our board may, from time to time, grant waivers from these restrictions, in itssole discretion. The relevant sections of our charter provide that, subject to the exceptions described below, no person or entity may own, or be deemed to own,beneficially or by virtue of the applicable constructive ownership provisions of the Code, more than 9.8%, in value or in number of shares, whichever is morerestrictive, of the outstanding shares of our common stock (the "common stock ownership limit") or 9.8% in value of the outstanding shares of all classes orseries of our stock (the "aggregate stock ownership limit"). We refer to the common stock ownership limit and the aggregate stock ownership limit collectively asthe "ownership limits." We refer to the person or entity that, but for operation of the ownership limits or another restriction on ownership and transfer of our stockas described below, would beneficially own or constructively own shares of our stock in violation of such limits or restrictions and, if appropriate in the context,a person or entity that would have been the record owner of such shares of our stock as a "prohibited owner."

The constructive ownership rules under the Code are complex and may cause shares of stock owned beneficially or constructively by a group of relatedindividuals and/or entities to be owned beneficially or constructively by one individual or entity. As a result, the acquisition of less than 9.8%, in value or innumber of shares, whichever is more restrictive, of the outstanding shares of our common stock, or less than 9.8% in value of the outstanding shares of all classesand series of our stock (or the acquisition by an individual or entity of an interest in an entity that owns, beneficially or constructively, shares of our stock), could,nevertheless, cause that individual or entity, or another individual or entity, to own beneficially or constructively shares of our stock in excess of the ownershiplimits.

26

Table of Contents

Our board of directors, in its sole discretion, may exempt, prospectively or retroactively, a particular stockholder from the ownership limits or establish adifferent limit on ownership (the "excepted holder limit") if our board of directors determines that:

• no individual's beneficial or constructive ownership of our stock will result in our being "closely held" under Section 856(h) of the Code (withoutregard to whether the ownership interest is held during the last half of a taxable year) or otherwise failing to qualify as a REIT; and

• such stockholder does not and will not own, actually or constructively, an interest in a tenant of ours (or a tenant of any entity owned or controlledby us) that would cause us to own, actually or constructively, more than a 9.9% interest (as set forth in Section 856(d)(2)(B) of the Code) in suchtenant (or our board of directors determines that revenue derived from such tenant will not affect our ability to qualify as a REIT).

Any violation or attempted violation of any such representations or undertakings will result in such stockholder's shares of stock being automaticallytransferred to a charitable trust. As a condition of granting the waiver or establishing the excepted holder limit, our board of directors may require an opinion ofcounsel or a ruling from the IRS, in either case in form and substance satisfactory to our board of directors, in its sole discretion, in order to determine or ensureour status as a REIT and such representations and undertakings from the person requesting the exception as our board of directors may require in its solediscretion to make the determinations above. Our board of directors may impose such conditions or restrictions as it deems appropriate in connection withgranting such a waiver or establishing an excepted holder limit. As of the date hereof, our board has granted limited waivers to certain holders of our commonstock.

In connection with granting a waiver of the ownership limits or creating an excepted holder limit or at any other time, our board of directors may from timeto time increase or decrease the common stock ownership limit, the aggregate stock ownership limit or both, for all other persons, unless, after giving effect tosuch increase, five or fewer individuals could beneficially own, in the aggregate, more than 49.9% in value of our outstanding stock or we would otherwise fail toqualify as a REIT. A reduced ownership limit will not apply to any person or entity whose percentage ownership of our common stock or our stock of all classesand series, as applicable, is, at the effective time of such reduction, in excess of such decreased ownership limit until such time as such person's or entity'spercentage ownership of our common stock or our stock of all classes and series, as applicable, equals or falls below the decreased ownership limit, but anyfurther acquisition of shares of our common stock or stock of all other classes or series, as applicable, will violate the decreased ownership limit.

Our charter further prohibits:

• any person from beneficially or constructively owning, applying certain attribution rules of the Code, shares of our stock that would result in ourbeing "closely held" under Section 856(h) of the Code (without regard to whether the ownership interest is held during the last half of a taxableyear) or otherwise cause us to fail to qualify as a REIT;

• any person from transferring shares of our stock if the transfer would result in shares of our stock being beneficially owned by fewer than 100persons (determined under the principles of Section 856(a)(5) of the Code); and

• any person from beneficially owning shares of our stock to the extent such ownership would result in our failing to qualify as a "domesticallycontrolled qualified investment entity" within the meaning of Section 897(h) of the Code.

Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares of our stock that will or may violate the ownershiplimits or any of the other restrictions on ownership and transfer of our stock described above, or who would have owned shares of our stock

27

Table of Contents

transferred to the trust as described below, must immediately give notice to us of such event or, in the case of an attempted or proposed transaction, give us atleast 15 days' prior written notice and provide us with such other information as we may request in order to determine the effect of such transfer on our status as aREIT.

If any transfer of shares of our stock would result in shares of our stock being beneficially owned by fewer than 100 persons, the transfer will be null andvoid and the intended transferee will acquire no rights in the shares. In addition, if any purported transfer of shares of our stock or any other event wouldotherwise result in any person violating the ownership limits or an excepted holder limit established by our board of directors, or in our being "closely held"under Section 856(h) of the Code (without regard to whether the ownership interest is held during the last half of a taxable year) or otherwise failing to qualify asa REIT or as a "domestically controlled qualified investment entity" within the meaning of Section 897(h) of the Code, then that number of shares (rounded up tothe nearest whole share) that would cause the violation will be automatically transferred to, and held by, a trust for the exclusive benefit of one or more charitableorganizations selected by us, and the intended transferee or other prohibited owner will acquire no rights in the shares. The automatic transfer will be effective asof the close of business on the business day prior to the date of the violative transfer or other event that results in a transfer to the trust. If the transfer to the trustas described above is not automatically effective, for any reason, to prevent violation of the applicable ownership limits or our being "closely held" underSection 856(h) of the Code (without regard to whether the ownership interest is held during the last half of a taxable year) or our otherwise failing to qualify as aREIT or as a "domestically controlled qualified investment entity," then our charter provides that the transfer of the shares will be null and void and the intendedtransferee will acquire no rights in such shares.

Shares of our stock held in the trust will be issued and outstanding shares. The prohibited owner will not benefit economically from ownership of any sharesof our stock held in the trust and will have no rights to distributions and no rights to vote or other rights attributable to the shares of our stock held in the trust.The trustee of the trust will exercise all voting rights and receive all distributions with respect to shares held in the trust for the exclusive benefit of the charitablebeneficiary of the trust. Any distribution made before we discover that the shares have been transferred to a trust as described above must be repaid by therecipient to the trustee upon demand by us. Subject to Maryland law, effective as of the date that the shares have been transferred to the trust, the trustee will havethe authority to rescind as void any vote cast by a prohibited owner before our discovery that the shares have been transferred to the trust and to recast the vote inaccordance with the desires of the trustee acting for the benefit of the charitable beneficiary of the trust. However, if we have already taken irreversible corporateaction, then the trustee may not rescind and recast the vote.

Shares of our stock transferred to the trustee are deemed offered for sale to us, or our designee, at a price per share equal to the lesser of (i) the price paid bythe prohibited owner for the shares (or, in the case of a devise or gift, the market price at the time of such devise or gift) and (ii) the market price on the date weaccept, or our designee, accepts such offer. We may reduce the amount so payable to the trustee by the amount of any distribution that we made to the prohibitedowner before we discovered that the shares had been automatically transferred to the trust and that are then owed by the prohibited owner to the trustee asdescribed above, and we may pay the amount of any such reduction to the trustee for distribution to the charitable beneficiary. We have the right to accept suchoffer until the trustee has sold the shares of our stock held in the trust as discussed below. Upon a sale to us, the interest of the charitable beneficiary in the sharessold terminates, and the trustee must distribute the net proceeds of the sale to the prohibited owner and must distribute any distributions held by the trustee withrespect to such shares to the charitable beneficiary.

If we do not buy the shares, the trustee must, within 20 days of receiving notice from us of the transfer of shares to the trust, sell the shares to a person orentity designated by the trustee who could own the shares without violating the ownership limits or the other restrictions on ownership and

transfer of our stock. After the sale of the shares, the interest of the charitable beneficiary in the shares transferred to the trust will terminate and the trustee mustdistribute to the prohibited owner an amount equal to the lesser of (i) the price paid by the prohibited owner for the shares (or, if the prohibited owner did notgive value for the shares in connection with the event causing the shares to be held in the trust (for example, in the case of a gift, devise or other suchtransaction), the market price of the shares on the day of the event causing the shares to be held in the trust) and (ii) the sales proceeds (net of any commissionsand other expenses of sale) received by the trust for the shares. The trustee may reduce the amount payable to the prohibited owner by the amount of anydistribution that we paid to the prohibited owner before we discovered that the shares had been automatically transferred to the trust and that are then owed bythe prohibited owner to the trustee as described above. Any net sales proceeds in excess of the amount payable to the prohibited owner must be paid immediatelyto the charitable beneficiary, together with any distributions thereon. In addition, if, prior to the discovery by us that shares of stock have been transferred to atrust, such shares of stock are sold by a prohibited owner, then such shares will be deemed to have been sold on behalf of the trust and, to the extent that theprohibited owner received an amount for or in respect of such shares that exceeds the amount that such prohibited owner was entitled to receive, such excessamount will be paid to the trustee upon demand. The prohibited owner has no rights in the shares held by the trustee.

In addition, if our board of directors determines in good faith that a transfer or other event has occurred that would violate the restrictions on ownership andtransfer of our stock described above, our board of directors may take such action as it deems advisable to refuse to give effect to or to prevent such transfer,including, but not limited to, causing us to redeem shares of our stock, refusing to give effect to the transfer on our books or instituting proceedings to enjoin thetransfer.

Every owner of 5% or more (or such lower percentage as required by the Code or the regulations promulgated thereunder) of our stock, within 30 days afterthe end of each taxable year, must give us written notice stating the stockholder's name and address, the number of shares of each class and series of our stockthat the stockholder beneficially owns and a description of the manner in which the shares are held. Each such owner must provide to us in writing suchadditional information as we may request in order to determine the effect, if any, of the stockholder's beneficial ownership on our status as a REIT and to ensurecompliance with the ownership limits. In addition, any person or entity that is a beneficial owner or constructive owner of shares of our stock and any person orentity (including the stockholder of record) who is holding shares of our stock for a beneficial owner or constructive owner must, on request, provide to us suchinformation as we may request in good faith in order to determine our status as a REIT and to comply with the requirements of any taxing authority orgovernmental authority or to determine such compliance and to ensure compliance with the ownership limits.

Any certificates representing shares of our stock will bear a legend referring to the restrictions on ownership and transfer of our stock described above.

These restrictions on ownership and transfer of our stock will not apply if our board of directors determines that it is no longer in our best interests toattempt to qualify, or to continue to qualify, as a REIT or that compliance is no longer required in order for us to qualify as a REIT.

The restrictions on ownership and transfer of our stock described above could delay, defer or prevent a transaction or a change in control that might involvea premium price for our common stock or otherwise be in the best interests of our stockholders.

Subject to certain exceptions, amendments that would, among other things, convert a limited partner into a general partner (except in connection with apermitted transfer of the general partner's interest), modify the limited liability of a limited partner, adversely alter a partner's right to receive any distributions orallocations of profits or losses, adversely alter or modify the redemption rights of limited partners and qualifying assignees (except as permitted in connectionwith a permitted Termination Transaction) or amend these restrictions must be approved by each limited partner that would be adversely affected by suchamendment; provided, however, that the consent of any individual partner adversely affected will not be required for any amendment or action that affects allpartners holding the same class or series of our operating partnership units on a uniform or pro rata basis, if approved by a majority of the partners (other than us,the general partner and entities controlled by us or the general partner, if there are any other limited partners) of such class or series.

Restrictions on General Partner's Authority

The general partner may not take any action in contravention of an express prohibition or limitation contained in the partnership agreement, including:

• admitting any person as a partner, except as otherwise provided in the partnership agreement;

• perform any act that would subject a limited partner to liability not contemplated in the partnership agreement or under the Maryland RevisedUniform Limited Partnership Act; or

• enter into any contract, mortgage, loan or other agreement that, in the absence of a default under such document, expressly prohibits or restricts usor our operating partnership from performing our or its specific obligations in connection with a redemption of operating partnership units asdescribed below or that expressly prohibits or restricts the ability of a limited partner to exercise its redemption rights in full without the writtenconsent of such limited partner.

In addition, without the consent of partners (including us, the general partner and entities controlled by us or the general partner) holding a majority of ouroperating partnership units then held by the partners (including us, the general partner and entities controlled by us or the general partner), entitled to vote on orconsent to such matter, the general partner may not do any of the following:

• amend, modify or terminate the partnership agreement, except as explicitly permitted therein;

• transfer any portion of its partnership interest or admit into the partnership any additional or successor general partner (other than to us or one ofour wholly owned subsidiaries or in connection with a permitted Termination Transaction);

32

• voluntarily withdraw as general partner except in connection with a permitted transfer of its entire interest to an entity that will become the newgeneral partner or in connection with a permitted Termination Transaction;

• make a general assignment for the benefit of creditors, appoint or acquiesce in the appointment of a custodian, receiver or trustee for all or anypart of the assets of our operating partnership; or

• institute any proceeding for bankruptcy by our operating partnership.

Distributions to Holders of Operating Partnership Units

The partnership agreement provides that holders of operating partnership units are generally entitled to receive distributions when, as and if authorized bythe general partner, on a pro rata basis in accordance with their respective operating partnership units (subject to the rights of the holders of any class of preferredpartnership interests that may be authorized and issued in the future).

Redemption/Exchange Rights

A limited partner or an assignee has the right, commencing on or after the date which is 12 months after its acquisition of operating partnership units, torequire our operating partnership to redeem part or all of such operating partnership units for cash based upon the fair market value of an equivalent number ofshares of our common stock at the time of the redemption, determined in accordance with and subject to adjustment as provided in the partnership agreement.Alternatively, we may elect to acquire those operating partnership units in exchange for shares of our common stock. Our acquisition will be on a one-for-onebasis, subject to adjustment in the event of stock splits, stock dividends, distributions of warrants or stock rights, specified extraordinary distributions and similarevents. A limited partner or assignee may not require us to redeem such limited partner's or assignee's operating partnership units if our election to acquire suchoperating partnership units in exchange for shares of our common stock would cause any person to violate the ownership limits or the other restrictions onownership and transfer of our common stock, after giving effect to any waivers or modifications of such limits granted by our board of directors. With eachredemption or exchange, we increase our percentage ownership interest in our operating partnership.

In addition, if our election to acquire operating partnership units tendered for redemption in exchange for shares of our common stock would cause anyperson to violate the restrictions on ownership and transfer of our stock and such excess operating partnership units (and any other operating partnership unitsthat the tendering limited partner agrees to treat as such) have a value of at least $50,000,000 (based on an operating partnership unit having a value equal to thetrailing ten-day daily trading price of our common stock) and we are eligible to file a registration statement on Form S-3 under the Securities Act, then we mayalso elect to redeem our operating partnership units with the proceeds from a public offering or private placement of our common stock. In the event we elect thisoption, we may require the other limited partners to also elect whether or not to participate. Participating limited partners will receive on the redemption date foreach operating partnership unit (subject to adjustment) the net proceeds per share received in the public offering but will have a limited opportunity to withdrawtheir operating partnership units from the redemption immediately prior to the pricing of the public offering.

Issuance of Units, Stock or Other Securities

The general partner of our operating partnership has the power to cause our operating partnership to issue additional units of partnership interest in one ormore classes or series. These additional units of partnership interest may include preferred partnership units or LTIP units. Generally, we may issue additionalshares of our stock, or rights, options, warrants or convertible or exchangeable securities

33

Table of Contents

having the right to subscribe for or purchase shares of our stock, only if we cause our operating partnership to issue to us (or the general partner) partnershipinterests or rights, options, warrants or convertible or exchangeable securities of our operating partnership having economic rights that are substantially similar tothe securities that we have issued.

Capital Contributions

The partnership agreement provides that the general partner may authorize the issuance of additional partnership interests in exchange for such capitalcontributions, if any, as the general partner may approve. Under the partnership agreement, we are generally obligated to contribute the net proceeds we receivefrom any offering of our shares of stock as additional capital to our operating partnership in exchange for additional operating partnership units issued to us or thegeneral partner.

The partnership agreement provides that we or the general partner may make additional capital contributions, including contributions of properties, to ouroperating partnership in exchange for additional operating partnership units. If we contribute (directly or indirectly through the general partner) additional capitaland receive additional operating partnership units in exchange for the capital contribution, our, or the general partner's, as applicable, percentage interest in ouroperating partnership will be increased on a proportionate basis based on the amount of the additional capital contributions and the value of our operatingpartnership at the time of the contributions. In addition, if we or the general partner contribute additional capital and receive additional operating partnershipunits for the capital contribution, the capital accounts of the partners may be adjusted upward or downward to reflect any unrealized gain or loss attributable tothe properties as if there were an actual sale of the properties at the fair market value thereof. No person has any preemptive, preferential or other similar rightwith respect to making additional capital contributions or loans to our operating partnership or the issuance or sale of any operating partnership units or otherpartnership interests.

Our operating partnership could issue preferred partnership interests in connection with acquisitions of property or otherwise. Any such preferredpartnership interests would have priority over common partnership interests with respect to distributions from our operating partnership, including the partnershipinterests that we own.

Borrowing by the Operating Partnership

The general partner may cause our operating partnership to borrow money and to issue and guarantee debt as the general partner deems necessary for theconduct of the activities of our operating partnership. Such debt may be secured, among other things, by mortgages, deeds of trust, liens or encumbrances on theproperties of our operating partnership.

Tax Matters

The general partner is the tax matters partner and "partnership representative" of our operating partnership and, as the sole trustee of the general partner, wehave the authority under the Code to handle tax audits on behalf of our operating partnership. In addition, as the sole trustee of the general partner, we have theauthority to arrange for the preparation and filing of our operating partnership's tax returns and to make tax elections under the Code on behalf of our operatingpartnership. The foregoing provisions will generally be relevant only to the extent our operating partnership admits additional partners such that it becomes apartnership (rather than a disregarded entity) for U.S. federal income tax purposes.

Allocations of Net Income and Net Losses to Partners

Subject to any special allocations that may be required under the terms of any class or series of partnership units created in the future, the net income or netloss of our operating partnership is

34

Table of Contents

generally allocated to the general partner and the limited partners of our operating partnership in accordance with their respective ownership of operatingpartnership units. However, in some cases, gains or losses may be disproportionately allocated to partners who have contributed property to or guaranteed debt ofour operating partnership. The allocations described above are subject to special allocations relating to depreciation deductions and to compliance with theprovisions of Sections 704(b) and 704(c) of the Code and the associated Treasury regulations. See "U.S. Federal Income Tax Considerations—Tax Aspects ofOur Operating Partnership and any Subsidiary Partnerships and Disregarded Entities." The foregoing provisions will generally be relevant only to the extent ouroperating partnership admits additional partners such that it becomes a partnership (rather than a disregarded entity) for U.S. federal income tax purposes.

In addition, our operating partnership may from time to time issue LTIP units to persons who provide services to our company for such consideration or forno consideration as we may determine to be appropriate, and admit such persons as limited partners. The terms of the LTIP units are specified in Exhibit C to thepartnership agreement, which addresses, among other things, vesting and forfeiture, allocations, distributions, redemption, conversion to common partnershipunits of our operating partnership ("OP Units"), voting rights and restrictions on transfer. In general, LTIP units are a class of partnership units of our operatingpartnership that, except as may be otherwise provided in the partnership agreement, our 2012 Restated Long Term Incentive Plan or any applicable awardagreement, will be entitled to receive the same per unit distribution of operating income as the OP Units. The LTIP units may be subject to vesting requirements.Initially, each LTIP unit will have a capital account balance of zero and, therefore, will not have full parity with OP Units with respect to liquidating distributions.However, the partnership agreement provides that "book gain," or economic appreciation, in assets realized by our operating partnership as a result of the actualsale of all or substantially all of our operating partnership's assets or the revaluation of our operating partnership's assets as provided by applicable Treasuryregulations will be allocated first to the holders of LTIP units until the capital account per LTIP unit is equal to the fair market value of a share of our commonstock, subject to certain adjustments. The partnership agreement provides that our operating partnership's assets will be revalued upon the occurrence of certainevents, including additional capital contributions, a liquidation of our operating partnership or the issuance of a partnership interest (including LTIP units).

Upon equalization of the capital accounts of the holders of LTIP units with the fair market value of the shares of our common stock, subject to certainadjustments, the LTIP units will achieve full parity with the OP Units for all purposes, including with respect to liquidating distributions. If such parity isreached, vested LTIP units will be convertible into an equal number of OP Units, and thereafter enjoy all the rights of OP Units. If a sale or revaluation of assetsoccurs at a time when our operating partnership's assets have appreciated sufficiently since the last revaluation, the LTIP units would achieve full parity with theOP Units upon such sale or revaluation. In the absence of sufficient appreciation in the value of our operating partnership's assets at the time of a sale orrevaluation, full parity would not be reached. Consequently, an LTIP unit may never convert into an OP Unit if the value of our operating partnership's assets hasnot appreciated sufficiently between revaluation dates to equalize the capital account per LTIP unit to the fair market value of a share of our common stock,subject to certain adjustments. Until and unless parity is reached, the value for a given number of vested LTIP units will be less than the value of an equal numberof shares of our common stock.

With respect to LTIP units that convert into OP Units, the partnership agreement provides that holders of OP Units are generally entitled to receivedistributions on a pro rata basis in accordance with their respective OP Units (subject to the rights of the holders of any class of preferred partnership intereststhat may be authorized and issued in the future). Pursuant to the terms of the partnership agreement, holders of LTIP units are not entitled to the redemptionrights described above unless, until and to the extent such LTIP units have been converted into OP Units.

Operations

We intend to cause the general partner of our operating partnership to manage our operating partnership in a manner that will enable us to maintain ourqualification as a REIT and to minimize any U.S. federal income tax liability.

The partnership agreement provides that our operating partnership will assume and pay when due, or reimburse us for payment of, all costs and expensesrelating to the operations of, or for the benefit of, our operating partnership.

Change of Control and Termination Transactions

A "Termination Transaction" means any direct or indirect transfer of all or any portion of our limited partnership interest in our operatingpartnership or any direct or indirect transfer of our interest in the general partner in connection with:

The consent of the limited partners to a Termination Transaction is not required if either:

(i) in connection with the Termination Transaction, each operating partnership unit is entitled to receive the "transaction consideration," defined asthe fair market value, at the time of the Termination Transaction, of an amount of cash, securities or other property equal to the product of:

• the number of shares of our common stock into which each operating partnership unit is then exchangeable; and

• the greatest amount of cash, securities or other property paid to the holder of one share of our common stock in consideration of suchshare pursuant to the Termination Transaction;

provided that, if, in connection with the Termination Transaction, a purchase, tender or exchange offer is made to and accepted by the holders of amajority of the outstanding shares of our common stock, the transaction consideration will refer to the fair market value of the greatest amount of cash,securities or other property which such holder would have received had it exercised its redemption right and received shares of our common stock inexchange for its operating partnership units immediately prior to the expiration of such purchase, tender or exchange offer and had accepted suchpurchase, tender or exchange offer; or

(ii) all of the following conditions are met: (a) substantially all of the assets directly or indirectly owned by our operating partnership prior to theannouncement of the Termination Transaction are, immediately after the Termination Transaction, owned directly or indirectly by our

(2) if we or the general partner, or our or its successor, is not a REIT with a single class of common equity securities that are publicly tradedon any U.S. national securities exchange, the right to redeem their interests in the surviving partnership at any time for cash in an amount equal tothe fair market value of such interests at the time of redemption, as determined at least once every calendar quarter by an independent appraisalfirm of recognized national standing retained by the surviving partnership.

Term

Our operating partnership will continue in full force and effect until dissolved in accordance with its terms or as otherwise provided by law.

Indemnification and Limitation of Liability

Maryland law permits a Maryland limited partnership to indemnify any partner, employee or agent from and against any and all claims whatsoever, exceptin the case of an action or failure to act by a partner that constitutes willful misconduct or recklessness, and subject to any standards or restrictions set forth in itspartnership agreement. To the fullest extent permitted by applicable law, the partnership agreement requires our operating partnership to indemnify us, ourdirectors, officers and employees, the general partner and its trustees, officers and employees, employees of our operating partnership and any other personswhom the general partner may designate, which we refer to collectively as "indemnitees", and each an "indemnitee", from and against any and all claims arisingfrom or that relate to the operations of our operating partnership in which any indemnitee may be involved, or is threatened to be involved, as a party, witness orotherwise unless:

• it is established by a final judgment of a court of competent jurisdiction that an act or omission of the indemnitee that is material to the mattergiving rise to the claim constituted fraud, intentional harm or gross negligence on the part of the indemnitee;

• the claim is brought by the indemnitee (other than to enforce the indemnitee's rights to indemnification or advance of expenses); or

37

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 qualifiedin its entirety by reference to Maryland law, including the MGCL, and our charter and bylaws. Copies of our charter and bylaws have been filed with the SECand are incorporated by reference as exhibits to the registration statement of which this prospectus is a part. See "Where You Can Find More Information."

Our Board of Directors

Our board of directors currently consists of eight directors. Our charter and bylaws provide that the number of directors constituting our board of directorsmay be increased or decreased only by a majority vote of our board of directors, provided that the number of directors may not be decreased to fewer than theminimum number required under the MGCL, nor increased to more than 15.

Subject to the terms of any class or series of preferred stock, vacancies on our board of directors may be filled only by a majority of the remaining directors,even if the remaining directors do not constitute a quorum, and any director elected to fill a vacancy will hold office for the remainder of the full term of thedirectorship in which the vacancy occurred and until his or her successor is duly elected and qualifies.

Each of our directors is elected by our stockholders to serve until the next annual meeting of our stockholders and until his or her successor is duly electedand qualifies. Holders of shares of our common stock have no right to cumulative voting in the election of directors. Consequently, the holders of a majority ofthe outstanding shares of our common stock can elect all of the directors then standing for election, and the holders of the remaining shares will not be able toelect any directors. Directors are elected by a plurality of all of the votes cast in the election of directors.

Removal of Directors

Our charter provides that a director may be removed only for cause (as defined in our charter) and only by the affirmative vote of a majority of the votesentitled to be cast generally in the election of directors. This provision, when coupled with the exclusive power of our board of directors to fill vacancies on ourboard of directors, precludes stockholders from removing incumbent directors (except for cause and upon a substantial affirmative vote) and filling the vacanciescreated by such removal with their own nominees.

Business Combinations

Under the MGCL, certain "business combinations" (including a merger, consolidation, statutory share exchange or, in certain circumstances, an assettransfer or issuance or reclassification of equity securities) between a Maryland corporation and an interested stockholder (defined generally as any person whobeneficially owns, directly or indirectly, 10% or more of the voting power of the corporation's outstanding voting stock or an affiliate or associate of thecorporation who, at any time during the two-year period immediately prior to the date in question, was the beneficial owner of 10% or more of the voting powerof the then-outstanding stock of the corporation) or an affiliate of such an interested stockholder are prohibited for five years after the most recent date on whichthe interested stockholder becomes an interested stockholder. Thereafter, any such business combination must generally be recommended by the board ofdirectors of the corporation and approved by the affirmative vote of at least (i) 80% of the votes entitled to be cast by holders of outstanding shares of votingstock of the corporation and (ii) two-thirds of the votes entitled to be cast by holders of voting stock of the corporation, other than shares held by the interestedstockholder with whom (or with whose affiliate) the business combination is to be effected or held by an affiliate or associate of the interested stockholder,unless, among other conditions, the corporation's common stockholders receive

39

Table of Contents

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 interestedstockholder for its shares. A person is not an interested stockholder under the statute if the board of directors approved in advance the transaction by which theperson otherwise would have become an interested stockholder. A corporation's board of directors may provide that its approval is subject to compliance, at orafter the time of approval, with any terms and conditions determined by the board.

Pursuant to the statute, our board of directors has by resolution exempted business combinations between us and any other person, provided that thebusiness combination is first approved by our board of directors (including a majority of our directors who are not affiliates or associates of such person).Consequently, the five-year prohibition and the supermajority vote requirements will not apply to a business combination between us and any other person if theboard of directors has first approved the combination. As a result, any person described in the preceding sentence may be able to enter into businesscombinations with us that may not be in the best interests of our stockholders, without compliance with the supermajority vote requirements and other provisionsof the statute. We cannot assure you that our board of directors will not amend or repeal this resolution in the future.

Control Share Acquisitions

The MGCL provides that holders of "control shares" of a Maryland corporation acquired in a "control share acquisition" have no voting rights with respectto such shares except to the extent approved by the affirmative vote of at least two-thirds of the votes entitled to be cast on the matter. Shares owned by theacquirer, an officer of the corporation or an employee of the corporation who is also a director of the corporation are excluded from shares entitled to vote on thematter.

"Control shares" are voting shares of stock that, if aggregated with all other such shares of stock owned by the acquirer, or in respect of which the acquirer isable to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquirer to exercise voting power inelecting directors within one of the following ranges of voting power:

• one-tenth or more but less than one-third;

• one-third or more but less than a majority; or

• a majority or more of all voting power.

Control shares do not include shares that the acquiring person is then entitled to vote as a result of having previously obtained stockholder approval orshares acquired directly from the corporation. A "control share acquisition" means the acquisition of issued and outstanding control shares, subject to certainexceptions.

A person who has made or proposes to make a control share acquisition, upon satisfaction of certain conditions (including an undertaking to pay expensesand making an "acquiring person statement" as described in the MGCL), may compel the board of directors to call a special meeting of stockholders to be heldwithin 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 anystockholders 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 or all of the control shares (except those for which voting rights havepreviously 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 shareacquisition by the acquirer 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 ofsuch meeting. If voting rights for control shares are approved at a

40

Table of Contents

stockholders' meeting and the acquirer becomes entitled to vote a majority of the shares entitled to vote, all other stockholders may exercise appraisal rights. Thefair 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 acquirer in the controlshare acquisition.

The control share acquisition statute does not apply to shares acquired in a merger, consolidation or statutory share exchange if the corporation is a party tothe transaction or acquisitions approved or exempted by the charter or bylaws of the corporation.

Our bylaws contain a provision exempting from the control share acquisition statute any and all acquisitions by any person of shares of our stock. Thisprovision may be amended or eliminated at any time in the future by our board of directors.

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 threeindependent directors to elect to be subject, by provision in its charter or bylaws or a resolution of its board of directors and notwithstanding any contraryprovision in the charter or bylaws, to any or all of five provisions of the MGCL that provide, respectively, for:

• a classified board;

• a two-thirds vote requirement for removing a director;

• a requirement that the number of directors be fixed only by vote of the board of directors;

• a requirement that a vacancy on the board be filled only by the remaining directors in office and (if the board is classified) for the remainder of thefull term of the class of directors in which the vacancy occurred; and

• a majority requirement for the calling of a stockholder-requested special meeting of stockholders.

Pursuant to Subtitle 8, we have elected to provide that vacancies on our board may be filled only by the remaining directors and that directors elected by theboard to fill vacancies will serve for the remainder of the full term of the directorship in which the vacancy occurred. Through provisions in our charter andbylaws unrelated to Subtitle 8, we already (i) vest in the board the exclusive power to fix the number of directorships and (ii) require, unless called by ourchairman of the board, our chief executive officer, our president or our board of directors, the written request of stockholders entitled to cast a majority of all ofthe votes entitled to be cast at such a meeting to call a special meeting.

Meetings of Stockholders

Pursuant to our bylaws, a meeting of our stockholders for the election of directors and the transaction of any business will be held annually on a date and atthe time and place set by our board of directors. The chairman of our board of directors, our chief executive officer, our president or our board of directors maycall 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 properlybe brought before a meeting of our stockholders must also be called by our secretary upon the written request of the stockholders entitled to cast a majority of allthe votes entitled to be cast on such matter at the meeting and containing the information required by our bylaws. Our secretary will inform the requestingstockholders of the reasonably estimated cost of preparing and delivering the notice of meeting (including our proxy materials), and the requesting stockholdermust pay such estimated cost before our secretary is required to prepare and deliver the notice of the special meeting.

Amendments to Our Charter and Bylaws

Except for those amendments permitted to be made without stockholder approval under Maryland law or our charter, our charter generally may be amendedonly if the amendment is first declared advisable by our board of directors and thereafter approved by the affirmative vote of stockholders entitled to cast amajority of all of the votes entitled to be cast on the matter.

Our board of directors has the power to adopt, alter or repeal any provision of our bylaws and to make new bylaws. In addition, stockholders may alter orrepeal any provision of our bylaws and adopt new bylaws with the approval by a majority of the votes entitled to be cast on the matter.

Forum Selection

Our bylaws require, subject to limited exceptions, that any derivative action or proceeding brought on our behalf, any action asserting a claim of breach ofany duty owed by any of our directors, officers or other employees to us or our stockholders and other similar actions, may be brought only in specified courts inthe State of Maryland. Although we believe this provision will benefit us by limiting costly and time-consuming litigation in multiple forums and by providingincreased consistency in the application of Maryland law in the types of lawsuits to which it applies, the provision may have the effect of discouraging lawsuitsagainst us or our directors, officers and other employees.

Transactions Outside the Ordinary Course of Business

Under the MGCL, a Maryland corporation generally may not dissolve, merge or consolidate with, or convert to, another entity, sell all or substantially all ofits assets or engage in a statutory share exchange unless the action is declared advisable by the board of directors and approved by the affirmative vote ofstockholders entitled to cast at least two-thirds of the votes entitled to be cast on the matter, unless a lesser percentage (but not less than a majority of all of thevotes entitled to be cast on the matter) is specified in the corporation's charter. Our charter provides that these actions must be approved by a majority of all of thevotes entitled to be cast on the matter.

Dissolution of Our Company

The dissolution of our company must be declared advisable by a majority of our entire board of directors and approved by the affirmative vote of the holdersof a majority of all of the votes entitled to be cast on the matter.

Advance Notice of Director Nominations and New Business

Our bylaws provide that, with respect to an annual meeting of our stockholders, nominations of individuals for election to our board of directors and theproposal of other business to be considered by our stockholders may be made only (i) pursuant to our notice of the meeting, (ii) by or at the direction of our boardof directors or (iii) by any stockholder who was a stockholder of record at the record date set by the board of directors for the purpose of determiningstockholders entitled to vote at the meeting, at the time of giving the notice required by our bylaws and at the time of the meeting (or any postponement oradjournment thereof), who is entitled to vote at the meeting on such business or in the election of such nominee and has provided notice to us within the timeperiod, and containing the information and other materials, specified in the advance notice provisions of our bylaws.

With respect to special meetings of stockholders, only the business specified in our notice of meeting may be brought before the meeting. Nominations ofindividuals for election to our board of directors may be made only (i) by or at the direction of our board of directors or (ii) if the meeting has been called for thepurpose of electing directors, by any stockholder who was a stockholder of record at the record date set by the board of directors for the purpose of determiningstockholders

entitled to vote at the meeting, at the time of giving the notice required by our bylaws and at the time of the meeting (or any postponement or adjournmentthereof), who is entitled to vote at the meeting in the election of each such nominee and who has provided notice to us within the time period, and containing theinformation and other materials, specified in the advance notice provisions of our bylaws.

The advance notice procedures of our bylaws provide that, to be timely, a stockholder's notice with respect to director nominations or other proposals for anannual meeting must be delivered to our corporate secretary at our principal executive office not earlier than the 150th day nor later than 5:00 p.m., Eastern Time,on the 120th day prior to the first anniversary of the date of the proxy statement for our preceding year's annual meeting. In the event that the date of the annualmeeting is advanced or delayed by more than 30 days from the first anniversary of the date of the preceding year's annual meeting, to be timely, a stockholder'snotice must be delivered not earlier than the 150th day prior to the date of such annual meeting and not later than 5:00 p.m., Eastern Time, on the close ofbusiness on the later of the 120th day prior to the date of such annual meeting or the tenth day following the day on which public announcement of the date ofsuch meeting is first made.

REIT Qualification

Our charter provides that our board of directors may authorize us to revoke or otherwise terminate our REIT election, without approval of our stockholders,if it determines that it is no longer in our best interests to continue to qualify as a REIT.

Effects of Certain Provisions of Maryland Law and of Our Charter and Bylaws

Our charter and bylaws and Maryland law contain provisions that may delay, defer or prevent a change in control or other transaction that might involve apremium price for shares of our common stock or otherwise be in the best interests of our stockholders, including business combination provisions, supermajorityvote requirements and advance notice requirements for director nominations and other stockholder proposals. Likewise, if the provision in our bylaws opting outof the control share acquisition provisions of the MGCL were rescinded or if we were to opt in to the classified board or other provisions of Subtitle 8, theseprovisions of the MGCL could have similar anti-takeover effects.

Indemnification and Limitation of Directors' and Officers' Liability

Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and itsstockholders for money damages, except for liability resulting from (i) actual receipt of an improper benefit or profit in money, property or services or (ii) activeand deliberate dishonesty that is established by a final judgment and that is material to the cause of action. Our charter contains a provision that eliminates theliability of our directors and officers to the maximum extent permitted by Maryland law.

The MGCL requires us (unless our charter provides otherwise, which our charter does not) to indemnify a director or officer who has been successful, on themerits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service in that capacity. The MGCL permits us toindemnify our present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurredby them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacitiesunless it is established that:

• the act or omission of the director or officer was material to the matter giving rise to the proceeding and (a) was committed in bad faith or (b) wasthe result of active and deliberate dishonesty;

43

Table of Contents

• the director or officer actually received an improper personal benefit in money, property or services; or

• in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

Under the MGCL, we may not indemnify a director or officer in a suit by us or in our right in which the director or officer was adjudged liable to us or in asuit in which the director or officer was adjudged liable on the basis that personal benefit was improperly received. A court may order indemnification if itdetermines that the director or officer is fairly and reasonably entitled to indemnification, even though the director or officer did not meet the prescribed standardof conduct or was adjudged liable on the basis that personal benefit was improperly received. However, indemnification for an adverse judgment in a suit by usor in our right, or for a judgment of liability on the basis that personal benefit was improperly received, is limited to expenses.

In addition, the MGCL permits us to advance reasonable expenses to a director or officer upon our receipt of:

• a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary forindemnification by us; and

• a written undertaking by or on behalf of the director or officer to repay the amount paid or reimbursed by us if it is ultimately determined that thedirector or officer did not meet the standard of conduct.

Our charter authorizes us to obligate ourselves, and our bylaws obligate us, to the maximum extent permitted by Maryland law in effect from time to time,to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advanceof final disposition of a proceeding to:

• any present or former director or officer who is made or threatened to be made a party to, or witness in, a proceeding by reason of his or herservice in that capacity; or

• any individual who, while a director or officer of our company and at our request, serves or has served as a director, officer, partner, trustee,member or manager of another corporation, REIT, limited liability company, partnership, joint venture, trust, employee benefit plan or any otherenterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in that capacity.

Our charter and bylaws also permit us to indemnify and advance expenses to any person who served a predecessor of ours in any of the capacities describedabove and to any employee or agent of our company or a predecessor of our company.

We have entered into indemnification agreements with each of our directors and executive officers that provide for indemnification to the maximum extentpermitted by Maryland law.

The partnership agreement provides that we, our directors, officers and employees, the general partner and its trustees, officers and employees, employees ofour operating partnership and any other persons whom the general partner may designate are indemnified to the fullest extent permitted by law. See "Descriptionof the Partnership Agreement of CyrusOne LP—Indemnification and Limitation of Liability."

Insofar as the foregoing provisions permit indemnification of directors, officers or persons controlling us for liability arising under the Securities Act, wehave been informed that, in the opinion of the SEC, this indemnification is against public policy as expressed in the Securities Act and is therefore unenforceable.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of the material U.S. federal income tax consequences of an investment in our common stock. Supplemental U.S. federal incometax considerations relevant to the ownership of the other securities offered by this prospectus may be provided in the prospectus supplement that relates to thosesecurities. For purposes of this section under the heading "U.S. Federal Income Tax Considerations," references to "CyrusOne Inc.," "we," "our" and "us"generally mean only CyrusOne Inc. and not its subsidiaries or other lower-tier entities, except as otherwise indicated, and references to "tenants" are to personswho are treated as lessees of real property for purposes of the REIT requirements including, in general, persons who are referred to as "customers" elsewhere inthis prospectus. This summary is based upon the Code, the regulations promulgated by the Treasury, rulings and other administrative pronouncements issued bythe IRS, and judicial decisions, all as currently in effect, and all of which are subject to differing interpretations or to change, possibly with retroactive effect. Noassurance can be given that the IRS would not assert, or that a court would not sustain, a position contrary to any of the tax consequences described below. Thesummary is also based upon the assumption that we and our subsidiaries and affiliated entities will operate in accordance with our and their applicableorganizational documents. This summary is for general information only and is not tax advice. It does not discuss any state, local or non-U.S. tax consequencesrelevant to us or an investment in any securities offered by this prospectus, and it does not purport to discuss all aspects of U.S. federal income taxation that maybe important to a particular investor in light of its investment or tax circumstances or to investors subject to special tax rules, such as:

and, except to the extent discussed below:

• tax-exempt organizations; and

• foreign investors.

This summary assumes that investors will hold their shares of our common stock as a capital asset, which generally means property held for investment.

The U.S. federal income tax treatment of holders of our common stock depends in some instances on determinations of fact and interpretations ofcomplex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. In addition, the tax consequences to anyparticular stockholder of holding or disposing of our common stock will depend on the stockholder's particular tax circumstances. You are urged toconsult your tax advisor regarding the U.S. federal, state, local, and foreign income and other tax consequences to you in light of your particularinvestment or tax circumstances of acquiring, holding, exchanging, or otherwise disposing of our common stock.

Taxation of CyrusOne Inc.

We have elected to be treated as a REIT commencing with our taxable year ended December 31, 2013, and intend to continue to operate in a manner thatwill allow us to qualify as a REIT.

The law firm of Skadden, Arps, Slate, Meagher & Flom LLP has acted as our special REIT tax counsel ("Special Tax Counsel"), and has provided us anopinion to the effect that, commencing with our taxable year ended December 31, 2013, we have been organized and have operated in conformity with therequirements for qualification and taxation as a REIT under the Code, and our proposed method of operation will enable us to meet the requirements forqualification and taxation as a REIT. It must be emphasized that the opinion of Special Tax Counsel is based on various assumptions relating to our organizationand operation, and is conditioned upon fact-based representations and covenants made by our management regarding our organization, assets, and income, andthe present and future conduct of our business operations. While we intend to operate so that we will continue to qualify as a REIT, given the highly complexnature of the rules governing REITs, the ongoing importance of factual determinations, and the possibility of future changes in our circumstances, no assurancecan be given by Special Tax Counsel or by us that we will qualify as a REIT for any particular year. The opinion is expressed as of the date issued. Special TaxCounsel has no obligation to advise us or our stockholders of any subsequent change in the matters stated, represented or assumed, or of any subsequent changein the applicable law. You should be aware that opinions of counsel are not binding on the IRS, and no assurance can be given that the IRS will not challenge theconclusions set forth in such opinions.

Qualification and taxation as a REIT depend on our ability to meet on a continuing basis, through actual operating results, distribution levels, diversity ofstock ownership, and various qualification requirements imposed upon REITs by the Code, all the results of which have not been and will not be reviewed bySpecial Tax Counsel. Our ability to qualify as a REIT also requires that we satisfy certain asset tests, some of which depend upon the fair market values of assetsthat we own directly or indirectly. Such values may not be susceptible to a precise determination. Accordingly, no assurance can be given that the actual results ofour operations for any taxable year have satisfied or will satisfy such requirements for qualification and taxation as a REIT.

We have received a private letter ruling from the IRS with respect to certain issues relevant to our qualification as a REIT. In general, the ruling provides,subject to the terms and conditions contained therein, that certain structural components of our properties (e.g., relating to the provision of electricity, HVAC,regulation of humidity, security and fire protection, and telecommunication services) and intangible assets, and certain services that we or CBI may provide,directly or through subsidiaries, to our tenants, will not adversely affect our qualification as a REIT. Although we may generally rely upon the ruling, noassurance can be given that the IRS will not challenge our qualification as a REIT on the basis of other issues or facts outside the scope of the ruling.

Taxation of REITs in General

As indicated above, our qualification and taxation as a REIT depend upon our ability to meet, on a continuing basis, various qualification requirementsimposed upon REITs by the Code. The material qualification requirements are summarized below under "—Requirements for Qualification—General." Whilewe intend to operate so that we continue to qualify as a REIT, no assurance can be given that the IRS will not challenge our qualification, or that we will be ableto operate in accordance with the REIT requirements in the future. See "—Failure to Qualify."

Provided that we qualify as a REIT, generally we will be entitled to a deduction for dividends that we pay and therefore will not be subject to U.S. federalcorporate income tax on our net taxable income that is currently distributed to our stockholders. This treatment substantially eliminates the "double taxation" atthe corporate and stockholder levels that generally results from an investment in a C corporation. A "C corporation" is a corporation that generally is required topay tax at the corporate

46

Table of Contents

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.In general, the income that we generate is taxed only at the stockholder level upon a distribution of dividends to our stockholders.

Any net operating losses, foreign tax credits and other tax attributes generally do not pass through to our stockholders, subject to special rules for certainitems such as the capital gains that we recognize. See "—Taxation of Stockholders—Taxation of Taxable U.S. Stockholders—Distributions."

If we qualify as a REIT, we will nonetheless be subject to U.S. federal tax in the following circumstances:

• We will be taxed at regular corporate rates on any undistributed net taxable income, including undistributed net capital gains.

• If we have net income from prohibited transactions, which are, in general, sales or other dispositions of inventory or property held primarily forsale to customers in the ordinary course of business, other than foreclosure property, such income will be subject to a 100% tax. See "—ProhibitedTransactions" and "—Foreclosure Property" below.

• If we elect to treat property that we acquire in connection with a foreclosure of a mortgage loan or certain leasehold terminations as "foreclosureproperty," we may thereby avoid the 100% tax on gain from a resale of that property (if the sale would otherwise constitute a prohibitedtransaction), but the income from the sale or operation of the property may be subject to corporate income tax at the highest applicable rate.

• If we fail to satisfy the 75% gross income test or the 95% gross income test, as discussed below, but nonetheless maintain our qualification as aREIT because we satisfy other requirements, we will be subject to a 100% tax on an amount based on the magnitude of the failure, as adjusted toreflect the profit margin associated with our gross income.

• If we violate the asset tests (other than certain de minimis violations) or other requirements applicable to REITs, as described below, and yetmaintain our qualification as a REIT because there is reasonable cause for the failure and other applicable requirements are met, we may besubject to a penalty tax. In that case, the amount of the penalty tax will be at least $50,000 per failure, and, in the case of certain asset test failures,will be determined as the amount of net income generated by the nonqualifying assets in question multiplied by the highest corporate tax rate ifthat amount exceeds $50,000 per failure.

• If we fail to distribute during each calendar year at least the sum of (i) 85% of our ordinary income for such year, (ii) 95% of our capital gain netincome for such year and (iii) any undistributed net taxable income from prior periods, we will be subject to a nondeductible 4% excise tax on theexcess of the required distribution over the sum of (a) the amounts that we actually distributed and (b) the amounts we retained and upon whichwe paid income tax at the corporate level.

• We may be required to pay monetary penalties to the IRS in certain circumstances, including if we fail to meet record-keeping requirementsintended to monitor our compliance with rules relating to the composition of a REIT's stockholders, as described below in "—Requirements forQualification—General."

• A 100% tax may be imposed on transactions between us and a TRS that do not reflect arm's length terms.

• If we acquire appreciated assets from a corporation that is not a REIT (i.e., a corporation taxable under subchapter C of the Code) in a transactionin which the adjusted tax basis of the assets in our hands is determined by reference to the adjusted tax basis of the assets in the

47

Table of Contents

hands of the subchapter C corporation, we may be subject to tax on such appreciation at the highest corporate income tax rate then applicable ifwe subsequently recognize gain on a disposition of any such assets during the five-year period following their acquisition from the subchapter Ccorporation.

• The earnings of our TRSs will generally be subject to U.S. federal corporate income tax.

In addition, we and our subsidiaries may be subject to a variety of taxes, including payroll taxes and state, local, and foreign income, property, gross receiptsand other taxes on our assets and operations. We could also be subject to tax in situations and on transactions not presently contemplated.

Requirements for Qualification—General

The Code defines a REIT as a corporation, trust or association:

1. that is managed by one or more trustees or directors;

2. the beneficial ownership of which is evidenced by transferable shares, or by transferable certificates of beneficial interest;

3. that would be taxable as a domestic corporation but for its election to be subject to tax as a REIT;

4. that is neither a financial institution nor an insurance company subject to specific provisions of the Code;

5. the beneficial ownership of which is held by 100 or more persons;

6. in which, during the last half of each taxable year, not more than 50% in value of the outstanding stock is owned, directly or indirectly, by five orfewer "individuals" (as defined in the Code to include specified tax-exempt entities); and

7. that meets other tests described below, including with respect to the nature of its income and assets.

The Code provides that conditions (1) through (4) must be met during the entire taxable year, and that condition (5) must be met during at least 335 days ofa taxable year of 12 months, or during a proportionate part of a shorter taxable year. Conditions (5) and (6) need not be met during a corporation's initial tax yearas a REIT (which, in our case, was 2013). Our charter provides restrictions regarding the ownership and transfers of our stock, which are intended to assist us insatisfying the stock ownership requirements described in conditions (5) and (6) above. These restrictions, however, may not ensure that we will, in all cases, beable to satisfy the share ownership requirements described in conditions (5) and (6) above. If we fail to satisfy these share ownership requirements, except asprovided in the next sentence, our status as a REIT will terminate. If, however, we comply with the rules contained in applicable Treasury regulations that requireus to ascertain the actual ownership of our shares and we do not know, or would not have known through the exercise of reasonable diligence, that we failed tomeet the requirement described in condition (6) above, we will be treated as having met this requirement.

To monitor compliance with the stock ownership requirements, we generally are required to maintain records regarding the actual ownership of our stock.To do so, we must demand written statements each year from the record holders of significant percentages of our stock pursuant to which the record holders mustdisclose the actual owners of the stock (i.e., the persons required to include our dividends in their gross income). We must maintain a list of those persons failingor refusing to comply with this demand as part of our records. We could be subject to monetary penalties if we fail to comply with these record-keepingrequirements. If you fail or refuse to comply with the demands, you

48

Table of Contents

will be required by Treasury regulations to submit a statement with your tax return disclosing your actual ownership of our stock and other information.

In addition, a corporation generally may not elect to become a REIT unless its taxable year is the calendar year. We adopted December 31 as our year-endand thereby satisfy this requirement.

Effect of Subsidiary Entities

Ownership of Partnership Interests. If we are a partner in an entity that is treated as a partnership for U.S. federal income tax purposes, Treasuryregulations provide that we are deemed to own our proportionate share of the partnership's assets, and to earn our proportionate share of the partnership's income,for purposes of the asset and gross income tests applicable to REITs. Our proportionate share of a partnership's assets and income is based on our capital interestin the partnership (except that for purposes of the 10% value test, described below, our proportionate share of the partnership's assets is based on ourproportionate interest in the equity and certain debt securities issued by the partnership). In addition, the assets and gross income of the partnership are deemed toretain the same character in our hands. Thus, our proportionate share of the assets and items of income of any of our subsidiary partnerships will be treated as ourassets and items of income for purposes of applying the REIT requirements.

We have control of any subsidiary entity treated as a partnership and intend to operate such entities in a manner consistent with the requirements for ourqualification as a REIT. If we become a limited partner or non-managing member in any entity treated as a partnership and such entity takes or expects to takeactions 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 possiblethat an entity treated as a partnership could take an action which could cause us to fail a gross income or asset test, and that we would not become aware of suchaction in time to dispose of our interest in such entity or take other corrective action on a timely basis. In that case, we could fail to qualify as a REIT unless wewere entitled to relief, as described below.

Disregarded Subsidiaries. If we own a corporate subsidiary that is a "qualified REIT subsidiary," that subsidiary is generally disregarded as a separateentity for U.S. federal income tax purposes, and all of the subsidiary's assets, liabilities and items of income, deduction and credit are treated as our assets,liabilities and items of income, deduction and credit, including for purposes of the gross income and asset tests applicable to REITs. A qualified REIT subsidiaryis any corporation, other than a TRS (as described below), that is directly or indirectly wholly-owned by a REIT. Other entities that are wholly-owned by us(either directly or through other disregarded entities), including single member limited liability companies that have not elected to be taxed as corporations forU.S. federal income tax purposes, are also generally disregarded as separate entities for U.S. federal income tax purposes, including for purposes of the REITincome and asset tests. For example, our operating partnership is currently a disregarded entity. Disregarded subsidiaries, along with any partnerships in whichwe hold an equity interest, are sometimes referred to herein as "pass-through subsidiaries."

In the event that a disregarded subsidiary of ours ceases to be wholly-owned—for example, if any equity interest in our operating partnership or otherdisregarded subsidiary is acquired by a person other than us or another disregarded subsidiary of ours—the subsidiary's separate existence would no longer bedisregarded for U.S. federal income tax purposes. Instead, the subsidiary would have multiple owners and would be treated as either a partnership or a taxablecorporation. Such an event could, depending on the circumstances, adversely affect our ability to satisfy the various asset and gross income requirementsapplicable to REITs, including the requirement that REITs generally may not own, directly or indirectly, more than 10% of the securities of another corporation.See "—Asset Tests" and "—Income Tests."

49

Table of Contents

Taxable REIT Subsidiaries. In general, we may jointly elect with a subsidiary corporation, whether or not wholly-owned, to treat such subsidiarycorporation as a TRS. We generally may not own more than 10% of the securities of a taxable corporation, as measured by voting power or value, unless we andsuch corporation elect to treat such corporation as a TRS. The separate existence of a TRS or other taxable corporation is not ignored for U.S. federal income taxpurposes. Accordingly, a TRS or other taxable subsidiary corporation generally is subject to corporate income tax on its earnings, which may reduce the cashflow that we and our subsidiaries generate in the aggregate, and may reduce our ability to make distributions to our stockholders.

We are not treated as holding the assets of a TRS or other taxable subsidiary corporation or as receiving any income that the subsidiary earns. Rather, thestock issued by a taxable subsidiary corporation to us is an asset in our hands, and we treat the dividends paid to us from such taxable subsidiary corporation, ifany, as income. This treatment can affect our income and asset test calculations, as described below. Because we do not include the assets and income of TRSs orother taxable subsidiary corporations on a look-through basis in determining our compliance with the REIT requirements, we may use such entities to undertakeindirectly activities that the REIT rules might otherwise preclude us from doing directly or through pass-through subsidiaries. For example, we may use TRSs orother taxable subsidiary corporations to perform services or conduct activities that give rise to certain categories of income such as management fees, or toconduct activities that, if conducted by us directly, would be treated in our hands as prohibited transactions.

The TRS rules impose a 100% excise tax on transactions between a TRS and its parent REIT or the REIT's tenants that are not conducted on an arm's lengthbasis. We intend that all of our transactions with our TRSs, if any, will be conducted on an arm's length basis.

Subsidiary REITs. We own certain of our assets through a subsidiary that is intended to be treated as a REIT. Our stock of any subsidiary REIT willgenerally be treated as a qualifying real estate asset for purposes of the REIT asset requirements (see "—Asset Tests" below), and any dividend income or gainsderived by us from such stock will generally be treated as income that qualifies for purposes of the REIT 95% and 75% income requirements (see "—IncomeTests" below), provided, in each case, that such subsidiary qualifies as a REIT. We and any subsidiary REIT are separate entities, each of which intends to qualifyas a REIT, and each of which must independently satisfy the various REIT qualification requirements as described herein. If our subsidiary REIT were to fail toqualify as a REIT, it would then be a regular taxable corporation, and its income would be subject to U.S. federal income tax. In addition, a failure of suchsubsidiary to qualify as a REIT would likely have an adverse effect on our ability to comply with the REIT asset and income requirements described below, andthus our ability to qualify as a REIT.

New Interest Deduction Limitations

Commencing in taxable years beginning after December 31, 2017, Section 163(j) of the Code limits the deductibility of net interest expense paid or accruedon debt properly allocable to a trade or business to 30% of "adjusted taxable income," subject to certain exceptions. Any deduction in excess of the limitation iscarried forward and may be used in a subsequent year, subject to the 30% limitation. Adjusted taxable income is determined without regard to certain deductions,including those for net interest expense, net operating loss carryforwards and, for taxable years beginning before January 1, 2022, depreciation, amortization anddepletion. Provided the taxpayer makes a timely election (which is irrevocable), the 30% limitation does not apply to a trade or business involving real propertydevelopment, redevelopment, construction, reconstruction, rental, operation, acquisition, conversion, disposition, management, leasing or brokerage. If we makethis election, we must use a generally less favorable depreciation system under the Code for our real property (including certain improvements). If we do notmake the election or if the election is determined not to be available with respect to all or certain of our business activities, the new interest deduction limitationcould change the amount of

50

Table of Contents

REIT taxable income we have and thus change the amount of distributions we must make to comply with the REIT requirements and avoid incurring corporatelevel tax. In addition, the foregoing limitations on the deduction of interest expense (including, if applicable, elections with respect thereto) will apply to ourTRSs or other regarded subsidiary entities.

Income Tests

In order to qualify as a REIT, we must satisfy two gross income requirements on an annual basis. First, at least 75% of our gross income for each taxableyear, excluding gross income from sales of inventory or dealer property in "prohibited transactions," discharge of indebtedness and certain hedging transactions,generally must be derived from "rents from real property," gains from the sale of real property, mortgages on real property, and shares in other REITs, interestincome derived from mortgage loans secured by real property (including certain types of mortgage-backed securities), dividends received from other REITs, andspecified income from temporary investments. Second, at least 95% of our gross income in each taxable year, excluding gross income from prohibitedtransactions, discharge of indebtedness and certain hedging transactions, must be derived from some combination of income that qualifies under the 75% grossincome test described above, as well as other dividends, interest, and gain from the sale or disposition of stock or securities, which need not have any relation toreal property. Income and gain from certain hedging transactions will be excluded from both the numerator and the denominator for purposes of both the 75%and 95% gross income tests.

Rents from Real Property. Rents we receive from a tenant will qualify as "rents from real property" for the purpose of satisfying the gross incomerequirements for a REIT described above only if all of the conditions described below are met.

• The amount of rent is not based in whole or in part on the income or profits of any person. However, an amount we receive or accrue generallywill not be excluded from the term "rents from real property" solely because it is based on a fixed percentage or percentages of receipts or sales;

• Neither we nor an actual or constructive owner of 10% or more of our stock actually or constructively owns 10% or more of the interests in theassets or net profits of a non-corporate tenant, or, if the tenant is a corporation, 10% or more of the total combined voting power of all classes ofstock entitled to vote or 10% or more of the total value of all classes of stock of the tenant. Rents we receive from such a tenant that is a TRS ofours, however, will not be excluded from the definition of "rents from real property" as a result of this condition if at least 90% of the space at theproperty to which the rents relate is leased to third parties, and the rents paid by the TRS are substantially comparable to rents paid by our othertenants for comparable space. Whether rents paid by a TRS are substantially comparable to rents paid by other tenants is determined at the timethe lease with the TRS is entered into, extended, and modified, if such modification increases the rents due under such lease. Notwithstanding theforegoing, however, if a lease with a "controlled TRS" is modified and such modification results in an increase in the rents payable by such TRS,any such increase will not qualify as "rents from real property." For purposes of this rule, a "controlled TRS" is a TRS in which the parent REITowns stock possessing more than 50% of the voting power or more than 50% of the total value of the outstanding stock of such TRS;

• Rent attributable to personal property that is leased in connection with a lease of real property is not greater than 15% of the total rent receivedunder the lease. If this condition is not met, then the portion of the rent attributable to personal property will not qualify as "rents from realproperty"; and

• We generally do not operate or manage the property or furnish or render services to our tenants, subject to a 1% de minimis exception and exceptas provided below. We are permitted,

51

Table of Contents

however, to perform directly certain services that are "usually or customarily rendered" in connection with the rental of space for occupancy onlyand are not otherwise considered "rendered to the occupant" of the property. Examples of these permitted services include the provision of light,heat, or other utilities, trash removal and general maintenance of common areas. In addition, we are permitted to employ an independentcontractor from whom we derive no revenue to provide customary services to our tenants, or a TRS, which may be wholly or partially owned byus, to provide both customary and non-customary services to our tenants without causing the rent that we receive from those tenants to fail toqualify as "rents from real property." Any amounts that we receive from a TRS with respect to the TRS's provision of non-customary serviceswill, however, be nonqualifying income under the 75% gross income test and, except to the extent received through the payment of dividends, the95% gross income test.

A significant portion of the value of our properties is attributable to structural components related to the provision of electricity, heating ventilation and airconditioning, regulation of humidity, security and fire protection, and telecommunications infrastructure. In addition, we or our affiliates will provide certainservices to tenants of our properties. We expect that our structural components will be treated as real property for purposes of the REIT gross income tests, andwe intend to structure the provision of services in a manner that does not prevent our rental income from qualifying as "rents from real property." We havereceived a private letter ruling from the IRS with respect to certain issues relevant to our qualification as a REIT. In general, the ruling provides, subject to theterms and conditions contained therein, that certain structural components of our properties (e.g., relating to the provision of electricity, HVAC, regulation ofhumidity, security and fire protection, and telecommunication services), and certain services that we or CBI may provide, directly or through subsidiaries, to ourtenants, will not adversely affect our qualification as a REIT. Although we may generally rely upon the ruling, no assurance can be given that the IRS will notchallenge our qualification as a REIT on the basis of other issues or facts outside the scope of the ruling. In addition, the ruling may not apply to our subsidiaryREIT, which was formed after our receipt of the ruling.

We intend to cause any services that are not "usually or customarily rendered," or that are for the benefit of a particular tenant in connection with the rentalof real property, to be provided through a TRS or through an "independent contractor." However, no assurance can be given that the IRS will concur with ourdetermination as to whether a particular service is usual or customary, or otherwise in this regard.

Interest Income. Interest income constitutes qualifying mortgage interest for purposes of the 75% gross income test (as described above) to the extent thatthe obligation upon which such interest is paid is secured by a mortgage on real property or an interest in real property. If we receive interest income with respectto a mortgage loan that is secured by both real property and other property, and the highest principal amount of the loan outstanding during a taxable yearexceeds the fair market value of the real property on the date that we acquired or originated the mortgage loan, the interest income will generally be apportionedbetween the real property and the other collateral, and our income from the arrangement will qualify for purposes of the 75% gross income test only to the extentthat the interest is allocable to the real property. In certain cases, personal property collateral securing a loan that we hold may be treated as real property forpurposes of the foregoing rules. Even if a loan is not secured by real property, or is undersecured, the income that it generates may nonetheless qualify forpurposes of the 95% gross income test. For these purposes, the term "interest" generally does not include any amount received or accrued, directly or indirectly, ifthe 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 generallywill not be excluded from the term "interest" solely by reason of being based on a fixed percentage or percentages of receipts or sales.

Dividend Income. We may directly or indirectly receive distributions from TRSs or other corporations that are not REITs or qualified REIT subsidiaries.These distributions generally are

52

Table of Contents

treated as dividend income to the extent of the earnings and profits of the distributing corporation. Such distributions will generally constitute qualifying incomefor purposes of the 95% gross income test, but not for purposes of the 75% gross income test. Any dividends that we receive from another REIT, however, willbe qualifying income for purposes of both the 95% and 75% gross income tests.

Fee Income. Any fee income that we earn will generally not be qualifying income for purposes of either gross income test. Any fees earned by a TRS,however, will not be included for purposes of our gross income tests.

Hedging Transactions. Any income or gain that we or our pass-through subsidiaries derive from instruments that hedge certain specified risks, such as therisk of changes in interest rates, will be excluded from gross income for purposes of both the 75% and 95% gross income tests, provided that specifiedrequirements are met, including the requirement that the instrument is entered into during the ordinary course of our business and that the instrument be properlyidentified as a hedge along with the risk that it hedges within prescribed time periods. Income and gain from all other hedging transactions will not be qualifyingincome for either the 95% or 75% gross income test.

Failure to Satisfy the Gross Income Tests. If we fail to satisfy one or both of the 75% or 95% gross income tests for any taxable year, we may still qualifyas a REIT for such year if we are entitled to relief under applicable provisions of the Code. These relief provisions will be generally available if (i) our failure tomeet these tests was due to reasonable cause and not due to willful neglect and (ii) following our identification of the failure to meet the 75% or 95% grossincome test for any taxable year, we file a schedule with the IRS setting forth each item of our gross income for purposes of the 75% or 95% gross income testfor such taxable year in accordance with Treasury regulations, which have not yet been issued. It is not possible to state whether we would be entitled to thebenefit of these relief provisions in all circumstances. If these relief provisions are inapplicable to a particular set of circumstances, we will not qualify as a REIT.Even if these relief provisions apply, and we retain our status as a REIT, the Code imposes a tax based upon the amount by which we fail to satisfy the particulargross income test.

Asset Tests

At the close of each calendar quarter, we must also satisfy five tests relating to the nature of our assets. First, at least 75% of the value of our total assetsmust be represented by some combination of "real estate assets," cash, cash items, U.S. government securities, and, under some circumstances, stock or debtinstruments purchased with new capital. For this purpose, real estate assets include interests in real property (and certain ancillary personal property), stock ofother corporations that qualify as REITs, some kinds of mortgage-backed securities and mortgage loans, and debt instruments (whether or not secured by realproperty) that are issued by a "publicly offered REIT" (i.e., a REIT that is required to file annual and periodic reports with the SEC under the Exchange Act).Assets that do not qualify for purposes of the 75% asset test are subject to the additional asset tests described below.

Second, the value of any one issuer's securities that we own may not exceed 5% of the value of our total assets.

Third, we may not own more than 10% of any one issuer's outstanding securities, as measured by either voting power or value. The 5% and 10% asset testsdo not apply to securities of TRSs and qualified REIT subsidiaries and the value prong of the 10% asset test does not apply to "straight debt" having specifiedcharacteristics and to certain other securities described below. Solely for purposes of the value prong of the 10% asset test, the determination of our interest in theassets 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 thepartnership or limited liability company, excluding for this purpose certain securities described in the Code.

53

Table of Contents

Fourth, the aggregate value of all securities of TRSs that we hold may not exceed 20% of the value of our total assets.

Fifth, no more than 25% of the total value of our assets may be represented by "nonqualified publicly offered REIT debt instruments" (i.e., real estate assetsthat would cease to be real estate assets if debt instruments issued by publicly offered REITs were not included in the definition of real estate assets).

Notwithstanding the general rule, as noted above, that for purposes of the REIT income and asset tests we are treated as owning our proportionate share ofthe underlying assets of a subsidiary partnership, if we hold indebtedness issued by a partnership, the indebtedness will be subject to, and may cause a violationof, the asset tests unless the indebtedness is a qualifying mortgage asset or other conditions are met. Similarly, although stock of another REIT is a qualifyingasset for purposes of the REIT asset tests, any non-mortgage debt that is issued by non-publicly offered REIT may not so qualify (although such debt will not betreated as "securities" for purposes of the value prong of the 10% asset test, as explained below).

Certain securities will not cause a violation of the value prong of the 10% asset test described above. Such securities include instruments that constitute"straight debt," which term generally excludes, among other things, securities having contingency features. A security does not qualify as "straight debt" where aREIT (or a controlled TRS of the REIT) owns other securities of the same issuer which do not qualify as straight debt, unless the value of those other securitiesconstitute, in the aggregate, 1% or less of the total value of that issuer's outstanding securities. In addition to straight debt, the Code provides that certain othersecurities will not violate the value prong of the 10% asset test. Such securities include (i) any loan made to an individual or an estate, (ii) certain rentalagreements pursuant to which one or more payments are to be made in subsequent years (other than agreements between a REIT and certain persons related tothe REIT under attribution rules), (iii) any obligation to pay rents from real property, (iv) securities issued by governmental entities that are not dependent inwhole or in part on the profits of (or payments made by) a nongovernmental entity, (v) any security (including debt securities) issued by another REIT and(vi) any debt instrument issued by a partnership if the partnership's income is of a nature that it would satisfy the 75% gross income test described above under"—Income Tests." In applying the value prong of the 10% asset test, a debt security issued by a partnership is not taken into account to the extent, if any, of theREIT's proportionate interest in the equity and certain debt securities issued by that partnership.

A significant portion of the value of our properties is attributable to structural components related to the provision of electricity, heating ventilation and airconditioning, regulation of humidity, security and fire protection, and telecommunication infrastructure. We expect that our structural components will be treatedas real property for purposes of the REIT asset tests, and we have received a private letter ruling from the IRS, subject to the terms and conditions containedtherein, generally to that effect. If, however, any structural components not covered by the IRS ruling are subsequently determined not to constitute real propertyfor purposes of the REIT asset tests, we could fail to satisfy such tests.

No independent appraisals have been obtained to support our conclusions as to the value of our total assets or the value of any particular security orsecurities. Moreover, the values of some assets may not be susceptible to a precise determination, and values are subject to change in the future. Furthermore, theproper classification of an instrument as debt or equity for U.S. federal income tax purposes may be uncertain in some circumstances, which could affect theapplication of the REIT asset requirements. Accordingly, there can be no assurance that the IRS will not contend that our interests in our subsidiaries or in thesecurities of other issuers will not cause a violation of the REIT asset tests.

However, certain relief provisions are available to allow REITs to satisfy the asset requirements or to maintain REIT qualification notwithstanding certainviolations of the asset tests and other

54

Table of Contents

requirements. For example, if we should fail to satisfy the asset tests at the end of a calendar quarter such a failure would not cause us to lose our REITqualification if we (i) satisfied the asset tests at the close of the preceding calendar quarter and (ii) the discrepancy between the value of our assets and the assetrequirements was not wholly or partly caused by an acquisition of non-qualifying assets, but instead arose from changes in the relative market values of ourassets. If the condition described in clause (ii) were not satisfied, we still could avoid disqualification by eliminating any discrepancy within 30 days after theclose of the calendar quarter in which it arose or by making use of the relief provisions described above.

In the case of de minimis violations of the 10% and 5% asset tests, a REIT may maintain its qualification despite a violation of such requirements if (i) thevalue of the assets causing the violation does not exceed the lesser of 1% of the REIT's total assets and $10,000,000 and (ii) the REIT either disposes of the assetscausing the failure within six months after the last day of the quarter in which it identifies the failure, or the relevant tests are otherwise satisfied within that timeframe.

Even if we did not qualify for the foregoing relief provisions, one additional provision allows a REIT that fails one or more of the asset tests to neverthelessmaintain its REIT qualification if (i) the REIT provides the IRS with a description of each asset causing the failure, (ii) the failure is due to reasonable cause andnot willful neglect, (iii) the REIT pays a tax equal to the greater of (a) $50,000 per failure and (b) the product of the net income generated by the assets thatcaused the failure multiplied by the highest applicable corporate tax rate and (iv) the REIT either disposes of the assets causing the failure within six months afterthe last day of the quarter in which it identifies the failure, or otherwise satisfies the relevant asset tests within that time frame.

Annual Distribution Requirements

In order to qualify as a REIT, we are required to annually distribute dividends, other than capital gain dividends, to our stockholders in an amount at leastequal to:

(i) the sum of

(a) 90% of our REIT taxable income, computed without regard to our net capital gains and the deduction for dividends paid; and

(b) 90% of our after tax net income, if any, from foreclosure property (as described below); minus

(ii) the excess of the sum of specified items of non-cash income over 5% of our REIT taxable income, computed without regard to our net capitalgains and the deduction for dividends paid.

We generally must make these distributions in the taxable year to which they relate, or in the following taxable year if declared before we timely file our taxreturn for the year and if paid with or before the first regular dividend payment after such declaration. These distributions will be treated as received by ourstockholders in the year in which paid.

To the extent that we distribute at least 90%, but less than 100%, of our REIT taxable income, as adjusted, we will be subject to tax at ordinary corporate taxrates on the retained portion. We may elect to retain, rather than distribute, some or all of our net long-term capital gains and pay tax on such gains. In this case,we could elect for our stockholders to include their proportionate shares of such undistributed long-term capital gains in income, and to receive a correspondingcredit for their share of the tax that we paid. Our stockholders would then increase the adjusted basis of their stock by the difference between (i) the amounts ofcapital gain dividends that we designated and that they include in their taxable income, and (ii) the tax that we paid on their behalf with respect to that income.

55

Table of Contents

To the extent that in the future we may have available net operating losses carried forward from prior tax years, such losses may, subject to limitations,reduce the amount of distributions that we must make in order to comply with the REIT distribution requirements. Such losses, however, will generally not affectthe tax treatment to our stockholders of any distributions that are actually made. See "—Taxation of Stockholders—Taxation of Taxable U.S. Stockholders—Distributions."

If we fail to distribute during each calendar year at least the sum of (i) 85% of our ordinary income for such year, (ii) 95% of our capital gain net income forsuch year and (iii) any undistributed net taxable income from prior periods, we will be subject to a non-deductible 4% excise tax on the excess of such requireddistribution over the sum of (a) the amounts actually distributed, plus (b) the amounts of income we retained and on which we have paid corporate income tax.

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 REITtaxable income. Accordingly, we anticipate that we generally will have sufficient cash or liquid assets to enable us to satisfy the distribution requirementsdescribed above. However, from time to time, we may not have sufficient cash or other liquid assets to meet these distribution requirements due to timingdifferences between the actual receipt of income and actual payment of deductible expenses, and the inclusion of income and deduction of expenses indetermining our taxable income. In addition, we may decide to retain our cash, rather than distribute it, in order to repay debt, acquire assets, or for other reasons.If these timing differences occur, we may sell assets, borrow funds to pay dividends or pay dividends through the distribution of other property (including sharesof our stock) in order to meet the distribution requirements, while preserving our cash.

If our taxable income for a particular year is subsequently determined to have been understated, we may be able to rectify a resultant failure to meet thedistribution requirements for a year by paying "deficiency dividends" to stockholders in a later year, which may be included in our deduction for dividends paidfor the earlier year. In this case, we may be able to avoid losing REIT qualification or being taxed on amounts distributed as deficiency dividends, subject to the4% excise tax described above. We will be required to pay interest based on the amount of any deduction taken for deficiency dividends.

For purposes of the 90% distribution requirement and excise tax described above, any dividend that we declare in October, November or December of anyyear and that is payable to a stockholder of record on a specified date in any such month will be treated as both paid by us and received by the stockholder onDecember 31 of such year, provided that we actually pay the dividend before the end of January of the following calendar year.

Prohibited Transactions

Net income that we derive from a prohibited transaction is subject to a 100% tax. The term "prohibited transaction" generally includes a sale or otherdisposition of property (other than foreclosure property, as discussed below) that is held as inventory or primarily for sale to customers in the ordinary course of atrade or business. We intend to conduct our operations so that no asset that we own (or are treated as owning) will be treated as, or as having been, held asinventory or for sale to customers, and that a sale of any such asset will not be treated as having been in the ordinary course of our business. Whether property isheld as inventory or "primarily for sale to customers in the ordinary course of a trade or business" depends on the particular facts and circumstances. Noassurance can be given that any property that we sell will not be treated as inventory or property held for sale to customers, or that we can comply with certainsafe-harbor provisions of the Code that would prevent such treatment. The 100% tax does not apply to gains from the sale of property that is held through a TRSor other taxable corporation, although such income will be subject to tax in the hands of the

56

Table of Contents

corporation at regular corporate rates. We intend to structure our activities to avoid prohibited transaction characterization.

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 inthe deferral of gain for U.S. federal income tax purposes. The failure of any such transaction to qualify as a like-kind exchange could require us to pay federalincome tax, possibly including the 100% prohibited transaction tax, depending on the facts and circumstances surrounding the particular transaction.

Derivatives and Hedging Transactions

We may enter into hedging transactions, including with respect to foreign currency exchange rate and interest rate exposure on one or more of our assets orliabilities. Any such hedging transactions could take a variety of forms, including the use of derivative instruments such as swap contracts, cap or floor contracts,futures or forward contracts, and options. Income from a hedging transaction (including gain from the sale, disposition, or termination of a position in such atransaction) generally will not constitute gross income for purposes of the 75% and 95% gross income tests if we properly identify the transaction as specified inapplicable Treasury regulations and we enter into such transaction (i) in the normal course of our business primarily to manage risk of interest rate changes orcurrency fluctuations with respect to borrowings made or to be made, or ordinary obligations incurred or to be incurred, to acquire or carry real estate assets;(ii) primarily to manage risk of currency fluctuations with respect to any item of income or gain that would be qualifying income under the 75% or 95% incometests; or (iii) in connection with the extinguishment of indebtedness with respect to which we have entered into a qualified hedging position described inclause (i) or the disposition of property with respect to which we have entered into a qualified hedging position described in clause (ii), primarily to manage therisks of such hedging positions. To the extent that we enter into other types of hedging transactions, the income from those transactions is likely to be treated asnon-qualifying income for purposes of both the 75% and 95% gross income tests. Moreover, to the extent that a position in a hedging transaction has positivevalue at any particular point in time, it may be treated as an asset that does not qualify for purposes of the REIT asset tests. We intend to structure any hedgingtransactions in a manner that does not jeopardize our qualification as a REIT. We may conduct some or all of our hedging activities (including hedging activitiesrelating to currency risk) through a TRS or other corporate entity, the income from which may be subject to U.S. federal income tax, rather than by participatingin the arrangements directly or through pass-through subsidiaries. No assurance can be given, however, that our hedging activities will not give rise to income orassets that do not qualify for purposes of the REIT tests, or that our hedging activities will not adversely affect our ability to satisfy the REIT qualificationrequirements.

Foreclosure Property

Foreclosure property is real property and any personal property incident to such real property (i) that we acquire as the result of having bid in the property atforeclosure, or having otherwise reduced the property to ownership or possession by agreement or process of law, after a default (or upon imminent default) on alease of the property or a mortgage loan held by us and secured by the property, (ii) for which we acquired the related loan or lease at a time when default wasnot imminent or anticipated and (iii) with respect to which we made a proper election to treat the property as foreclosure property. We generally will be subject totax at the maximum corporate rate (currently 35%) on any net income from foreclosure property, including any gain from the disposition of the foreclosureproperty, other than income that would otherwise be qualifying income for purposes of the 75% gross income test. Any gain from the sale of property for which aforeclosure property election

57

Table of Contents

has been made will not be subject to the 100% tax on gains from prohibited transactions described above, even if the property would otherwise constituteinventory or dealer property. We do not anticipate receiving any income from foreclosure property that does not qualify for purposes of the 75% gross incometest.

Penalty Tax

Any redetermined rents, redetermined deductions, excess interest, or redetermined TRS service income that we or our TRSs generate will be subject to a100% 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 aTRS, redetermined deductions and excess interest represent any amounts that are deducted by a TRS for amounts paid to us that are in excess of the amounts thatwould have been deducted based on arm's length negotiations, and redetermined TRS service income is income of a TRS attributable to services provided to, oron behalf of, us (other than services furnished or rendered to a tenant of ours) to the extent such income is lower than the income the TRS would have earnedbased on arm's length negotiations. Rents that we receive will not constitute redetermined rents if they qualify for certain safe harbor provisions contained in theCode.

From time to time, our TRS may provide services to our tenants. We intend to set the fees paid to our TRS for such services at arm's length rates, althoughthe fees paid may not satisfy the safe-harbor provisions described above. These determinations are inherently factual, and the IRS has broad discretion to assertthat amounts paid between related parties should be reallocated to clearly reflect their respective incomes. If the IRS successfully made such an assertion, wewould 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.

Failure to Qualify

If we fail to satisfy one or more requirements for REIT qualification other than the income or asset tests, we could avoid disqualification as a REIT if ourfailure is due to reasonable cause and not to willful neglect and we pay a penalty of $50,000 for each such failure. Relief provisions are also available for failuresof the income tests and asset tests, as described above in "—Income Tests" and "—Asset Tests."

If we fail to qualify for taxation as a REIT in any taxable year, and the relief provisions described above do not apply, we would be subject to tax, includingany applicable alternative minimum tax, on our taxable income at regular corporate rates. We cannot deduct distributions to stockholders in any year in which weare not a REIT, nor would we be required to make distributions in such a year. In this situation, to the extent of current and accumulated earnings and profits,distributions to stockholders would be taxable as regular corporate dividends. Such dividends paid to U.S. stockholders that are individuals, trusts and estatesmay be taxable at the preferential income tax rates for qualified dividends. In addition, subject to the limitations of the Code, corporate distributees may beeligible for the dividends received deduction. Unless we are entitled to relief under specific statutory provisions, we would also be disqualified from re-electingto be taxed as a REIT for the four taxable years following the year during which we lost our qualification. It is not possible to state whether, in all circumstances,we would be entitled to this statutory relief.

Tax Aspects of Our Operating Partnership and any Subsidiary Partnerships and Disregarded Entities

General. All of our investments will be held through our operating partnership, which, as noted above, is currently treated as a disregarded entity for U.S.federal income tax purposes. In addition, our operating partnership holds certain of its investments indirectly through subsidiary entities that are

58

Table of Contents

treated as partnerships or disregarded entities for U.S. federal income tax purposes. In general, entities that are treated as partnerships or disregarded entities forU.S. federal income tax purposes are "pass-through" entities which are generally not required to pay federal income tax. Rather, partners or members of suchentities are allocated their shares of the items of income, gain, loss, deduction and credit of the partnership or limited liability company, and are potentiallyrequired to pay tax (or, if the partner or member is a REIT, it would be subject to a distribution requirement) on this income, without regard to whether theyreceive a distribution from the partnership or limited liability company. We will include in our income our share of these partnership and limited liabilitycompany 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 through our operating partnership and the subsidiary partnerships and limitedliability companies, based on our capital interest in each such entity. See "—Taxation of CyrusOne Inc."

Entity Classification. Our interests in our operating partnership and the subsidiary partnerships and limited liability companies involve special taxconsiderations, including the possibility that the IRS might challenge the status of these entities as partnerships or disregarded entities (as applicable), as opposedto associations taxable as corporations for U.S. federal income tax purposes. If our operating partnership or a subsidiary partnership or limited liability companywere treated as an association, it would be taxable as a corporation and would be required to pay an entity-level tax on its income. In this situation, the characterof 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 CyrusOne Inc.—Asset Tests" and "—Income Tests." This, in turn, could prevent us from qualifying as a REIT. See "—Failure to Qualify" for adiscussion of the effect of our failure to meet these tests. In addition, a change in the tax status of our operating partnership, a subsidiary partnership or limitedliability company might be treated as a taxable event. If so, we might incur a distribution requirement without a corresponding receipt of cash. We believe thatour operating partnership and each of our other partnerships and limited liability companies will be classified as partnerships or disregarded entities for U.S.federal income tax purposes.

Allocations of Income, Gain, Loss and Deduction. A partnership agreement (or, in the case of a limited liability company treated as a partnership for U.S.federal income tax purposes, the limited liability company agreement) will generally determine the allocation of partnership income and loss among partners.Generally, Section 704(b) of the Code and the Treasury regulations thereunder require that partnership allocations respect the economic arrangement of thepartners. If an allocation of partnership income or loss does not comply with the requirements of Section 704(b) of the Code and the Treasury regulationsthereunder, the item subject to the allocation will be reallocated in accordance with the partners' interests in the partnership. This reallocation will be determinedby taking into account all of the facts and circumstances relating to the economic arrangement of the partners with respect to such item. In the event that ouroperating partnership becomes a partnership (rather than a disregarded entity) for U.S. federal income tax purposes, we intend that any allocations of taxableincome and loss will 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 ordepreciated property that is contributed to a partnership (including a limited liability company treated as a partnership for U.S. federal income tax purposes) inexchange for an interest in the partnership, must be allocated in a manner so that the contributing partner is charged with the unrealized gain or benefits from theunrealized loss associated with the property at the time of the contribution, as adjusted from time to time. The amount of the unrealized gain or unrealized lossgenerally 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(this

59

Table of Contents

difference is referred to as a book-tax difference), as adjusted from time to time. These allocations are solely for U.S. federal income tax purposes and do notaffect the book capital accounts or other economic or legal arrangements among the partners. In the event that our operating partnership becomes a partnership(rather than a disregarded entity) for U.S. federal income tax purposes, we intend that any allocations will be made in a manner consistent with Section 704(c) ofthe Code and the Treasury regulations thereunder.

Any property acquired by a partnership in which we invest in a taxable transaction will initially have a tax basis equal to its fair market value, andSection 704(c) of the Code will not apply.

New Partnership Audit Rules. The Bipartisan Budget Act of 2015 changes the rules applicable to U.S. federal income tax audits of partnerships. Under thenew rules, among other changes and subject to certain exceptions, any audit adjustment to items of income, gain, loss, deduction or credit of a partnership (andany partner's distributive share thereof) is determined, and taxes, interest or penalties attributable thereto are assessed and collected, at the partnership level.Although certain aspects of these new rules remain uncertain, it is possible that they could result in partnerships in which we directly or indirectly invest beingrequired 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 berequired 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 additionalcorporate-level taxes as a result of the related audit adjustment.

Taxation of Stockholders

Taxation of Taxable U.S. Stockholders

The following is a summary of certain U.S. federal income tax consequences of the ownership and disposition of our stock applicable to taxable U.S.stockholders. A "U.S. stockholder" is a beneficial owner of our common stock that is, for U.S. federal income tax purposes:

• an individual who is a citizen or resident of the United States;

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

• an estate, the income of which is includable in gross income for U.S. federal income tax purposes regardless of its source; or

• a trust if (a) a U.S. court is able to exercise primary supervision over the administration of such trust and one or more U.S. fiduciaries have theauthority to control all substantial decisions of the trust or (b) that trust has a valid election in effect under applicable Treasury regulations to betreated as a domestic trust for U.S. federal income tax purposes.

If a partnership, including for this purpose any entity that is treated as a partnership for U.S. federal income tax purposes, holds our common stock, the taxtreatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. An investor that is a partnershipand the partners in such partnership should consult their tax advisors about the U.S. federal income tax consequences of the acquisition, ownership anddisposition of our common stock.

Distributions. So long as we qualify as a REIT, the distributions that we make to our taxable U.S. stockholders out of current or accumulated earnings andprofits that we do not designate as capital gain dividends will generally be taken into account by such stockholders as ordinary income and will not be eligible forthe dividends received deduction for corporations. With limited exceptions, our dividends are not eligible for taxation at the preferential income tax rates forqualified dividends

60

Table of Contents

received by most U.S. stockholders that are individuals, trusts and estates from taxable C corporations. Such stockholders, however, are taxed at the preferentialrates on dividends designated by and received from REITs to the extent that the dividends are attributable to:

• income retained by the REIT in the prior taxable year on which the REIT was subject to corporate level income tax (less the amount of tax);

• dividends received by the REIT from TRSs or other taxable C corporations;

• dividends received by the REIT from other REITs to the extent designated by such other REITs as qualified dividends, or

• income in the prior taxable year from sales of "built-in gain" property acquired by the REIT from C corporations in carryover basis transactions(less the amount of corporate tax on such income).

In addition, for taxable years that begin after December 31, 2017 and before January 1, 2026, U.S. stockholders that are individuals, trusts or estates aregenerally entitled to a deduction equal to 20% of the aggregate amount of ordinary income dividends received from a REIT (not including capital gain dividendsor dividends eligible for the preferential rates applicable to qualified dividends as described above), subject to certain limitations. Under final regulations recentlyissued by the Internal Revenue Service, in order to qualify for this deduction with respect to a dividend on our common shares, a stockholder must hold suchshares for more than 45 days during the 91-day period beginning on the date which is 45 days before the date on which such shares become ex-dividend withrespect to such dividend (taking into account certain special holding period rules that may, among other consequences, reduce a shareholder's holding periodduring any period in which the shareholder has diminished its risk of loss with respect to the shares). Stockholders are urged to consult their tax advisors as totheir ability to claim this deduction.

Distributions that we designate as capital gain dividends will generally be taxed to our U.S. stockholders as long-term capital gains, to the extent that suchdistributions do not exceed our actual net capital gain for the taxable year, without regard to the period for which the stockholder that receives such distributionhas held its stock. We may elect to retain and pay taxes on some or all of our net long-term capital gains, in which case we may elect to treat our U.S.stockholders as having received, solely for tax purposes, our undistributed capital gains, and the stockholders as receiving a corresponding credit for taxes thatwe paid on such undistributed capital gains. See "Taxation of CyrusOne Inc.—Annual Distribution Requirements." Corporate stockholders may be required totreat up to 20% of some capital gain dividends as ordinary income. Long-term capital gains are generally taxable at reduced maximum U.S. federal rates in thecase of U.S. stockholders that are individuals, trusts or estates, and ordinary income rates in the case of U.S. stockholders that are corporations. Capital gainsattributable to the sale of depreciable real property held for more than 12 months are subject to a 25% maximum U.S. federal income tax rate for taxpayers whoare taxed as individuals, to the extent of previously claimed depreciation deductions.

Distributions in excess of our current and accumulated earnings and profits will generally represent a return of capital and will not be taxable to astockholder to the extent that the amount of such distributions does not exceed the adjusted basis of the stockholder's shares in respect of which the distributionswere made. Rather, the distribution will reduce the adjusted basis of the stockholder's shares. To the extent that such distributions exceed the adjusted basis of astockholder's shares, the stockholder generally must include such distributions in income as long-term capital gain if the shares have been held for more than oneyear, or short-term capital gain if the shares have been held for one year or less. In addition, any dividend that we declare in October, November or December ofany year and that is payable to a stockholder of record on a specified date in any such month will be treated as

both paid by us and received by the stockholder on December 31 of such year, provided that we actually pay the dividend before the end of January of thefollowing calendar year.

To the extent that we have available net operating losses and capital losses carried forward from prior tax years, such losses may, subject to limitations,reduce the amount of distributions that we must make in order to comply with the REIT distribution requirements. See "Taxation of CyrusOne Inc.—AnnualDistribution Requirements." Such losses, however, are not passed through to stockholders and do not offset income of stockholders from other sources, norwould such losses affect the character of any distributions that we make, which are generally subject to tax in the hands of stockholders to the extent that we havecurrent or accumulated earnings and profits.

Dispositions of Our Stock. If a U.S. stockholder sells or disposes of shares of our stock, the stockholder will generally recognize gain or loss for U.S.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 orother disposition and the stockholder's adjusted tax basis in the shares of stock. In general, capital gains recognized by individuals, trusts and estates upon thesale or disposition of our stock will be subject to a reduced maximum U.S. federal income tax rate if the stock is held for more than one year, and will be taxed atordinary income rates if the stock is held for one year or less. Gains recognized by stockholders that are corporations are subject to U.S. federal income tax atordinary income rates, whether or not such gains are classified as longterm capital gains. Capital losses recognized by a stockholder upon the disposition of ourstock that was held for more than one year at the time of disposition will be considered long-term capital losses, and are generally available only to offset capitalgain income of the stockholder but not ordinary income (except in the case of individuals, who may also offset up to $3,000 of ordinary income each year). Inaddition, any loss upon a sale or exchange of shares of our stock by a stockholder who has held the shares for six months or less, after applying holding periodrules, will be treated as a long-term capital loss to the extent of actual or deemed distributions that we make that are required to be treated by the stockholder aslong-term capital gain.

If an investor recognizes a loss upon a subsequent disposition of our stock or other securities in an amount that exceeds a prescribed threshold, it is possiblethat the provisions of Treasury regulations involving "reportable transactions" could apply, with a resulting requirement to separately disclose the loss-generatingtransaction to the IRS. These regulations, though directed towards "tax shelters," are broadly written and apply to transactions that would not typically beconsidered tax shelters. The Code imposes significant penalties for failure to comply with these requirements. You should consult your tax advisor concerningany possible disclosure obligation with respect to the receipt or disposition of our stock or securities or transactions that we might undertake directly or indirectly.Moreover, you should be aware that we and other participants in the transactions in which we are involved (including their advisors) might be subject todisclosure or other requirements pursuant to these regulations.

Passive Activity Losses and Investment Interest Limitations. Distributions that we make and gains arising from the sale or exchange by a U.S. stockholderof our stock will not be treated as passive activity income. As a result, stockholders will not be able to apply any "passive losses" against income or gain relatingto our stock. To the extent that distributions we make do not constitute a return of capital, they will be treated as investment income for purposes of computingthe investment interest limitation.

Taxation of Non-U.S. Stockholders

The following is a summary of certain U.S. federal income and estate tax consequences of the ownership and disposition of our stock applicable to non-U.S.stockholders. A "non-U.S. stockholder" is a beneficial owner of our common stock other than a partnership or U.S. stockholder.

Table of Contents

Ordinary Dividends. The portion of dividends received by non-U.S. stockholders that (i) is payable out of our earnings and profits, (ii) is not attributableto capital gains that we recognize and (iii) is not effectively connected with a U.S. trade or business of the non-U.S. stockholder, will be subject to U.S.withholding tax at the rate of 30%, unless reduced or eliminated by treaty.

In general, non-U.S. stockholders will not be considered to be engaged in a U.S. trade or business solely as a result of their ownership of our stock. In caseswhere the dividend income from a non-U.S. stockholder's investment in our stock is, or is treated as, effectively connected with the non-U.S. stockholder'sconduct of a U.S. trade or business, the non-U.S. stockholder generally will be subject to U.S. federal income tax at graduated rates, in the same manner as U.S.stockholders are taxed with respect to such dividends. Such effectively connected income must generally be reported on a U.S. income tax return filed by or onbehalf of the non-U.S. stockholder. The income may also be subject to a branch profits tax at the rate of 30% (unless reduced or eliminated by treaty) in the caseof a non-U.S. stockholder that is a corporation.

Non-Dividend Distributions. Unless our stock constitutes a U.S. real property interest ("USRPI"), distributions that we make which are not dividends outof our earnings and profits will not be subject to U.S. income tax. If we cannot determine at the time a distribution is made whether or not the distribution willexceed current and accumulated earnings and profits, the distribution will be subject to withholding at the rate applicable to dividends. The non-U.S. stockholdermay seek a refund from the IRS of any amounts withheld if it is subsequently determined that the distribution was, in fact, in excess of our current andaccumulated earnings and profits. If our stock constitutes a USRPI, as described below, distributions that we make in excess of the sum of (i) the stockholder'sproportionate share of our earnings and profits, plus (ii) the stockholder's basis in its stock, will be taxed under the Foreign Investment in Real Property Tax Actof 1980 ("FIRPTA"), at the rate of tax, including any applicable capital gains rates, that would apply to a U.S. stockholder of the same type (e.g., an individual ora corporation, as the case may be), and the collection of the tax may be enforced by a withholding at a rate of 15% of the amount by which the distributionexceeds the stockholder's share of our earnings and profits.

Capital Gain Dividends. Under FIRPTA, a distribution that we make to a non-U.S. stockholder, to the extent attributable to gains from dispositions ofUSRPIs that we held directly or through pass-through subsidiaries, or USRPI capital gains, will, except as described below, be considered effectively connectedwith a U.S. trade or business of the non-U.S. stockholder and will be subject to U.S. income tax at the rates applicable to U.S. individuals or corporations,without regard to whether we designate the distribution as a capital gain dividend. See above under "—Taxation of Non-U.S. Stockholders—OrdinaryDividends," for a discussion of the consequences of income that is effectively connected with a U.S. trade or business. In addition, we will be required towithhold tax equal to the highest corporate tax rate applied to the maximum amount that could have been designated as USRPI capital gain dividends.Distributions subject to FIRPTA may also be subject to a branch profits tax at the rate of 30% (unless reduced or eliminated by treaty) in the hands of a non-U.S.stockholder that is a corporation. A distribution is not attributable to USRPI capital gain if we held an interest in the underlying asset solely as a creditor. Capitalgain dividends received by a non-U.S. stockholder that are attributable to dispositions of our assets other than USRPIs are not subject to U.S. federal income orwithholding tax, unless (i) the gain is effectively connected with the non-U.S. stockholder's U.S. trade or business, in which case the non-U.S. stockholder wouldbe subject to the same treatment as U.S. stockholders with respect to such gain, except that a non-U.S. stockholder that is a corporation may also be subject to abranch profits tax at the rate of 30% (unless reduced or eliminated by treaty), or (ii) the non-U.S. stockholder is a nonresident alien individual who was present inthe United States for 183 days or more during the taxable year and certain other requirements are met, in which case the non-U.S. stockholder will incur a 30%tax on his capital gains. A significant portion of our assets are USRPIs.

63

Table of Contents

A capital gain dividend that would otherwise have been treated as a USRPI capital gain will not be so treated or be subject to FIRPTA, and generally willnot be treated as income that is effectively connected with a U.S. trade or business, and instead will be treated in the same manner as an ordinary dividend (see"—Taxation of Non-U.S. Stockholders—Ordinary Dividends"), if (i) the capital gain dividend is received with respect to a class of stock that is regularly tradedon an established securities market located in the United States and (ii) the recipient non-U.S. stockholder does not own more than 10% of that class of stock atany time during the year ending on the date on which the capital gain dividend is received. Our common stock is, and we anticipate that it will continue to be,"regularly traded" on an established securities exchange.

Dispositions of Our Stock. Unless our stock constitutes a USRPI, a sale of our stock by a non-U.S. stockholder generally will not be subject to U.S.taxation. Subject to certain exceptions discussed below, our stock will be treated as a USRPI if, at any time during a prescribed testing period, 50% or more ofour assets consist of interests in real property located within the United States, excluding, for this purpose, interests in real property solely in a capacity as acreditor. We believe that 50% or more of our assets consists of USRPIs.

Even if the foregoing 50% test is met, however, our stock will not constitute a USRPI if we are a "domestically controlled qualified investment entity." Adomestically controlled qualified investment entity includes a REIT, less than 50% of the value of which is held, directly or indirectly, by non-U.S. stockholdersat all times during a specified testing period (after applying certain presumptions regarding the ownership of our stock, as described in Section 897(h)(4)(E) ofthe Code). As described above, our charter contains restrictions designed to protect our status as a "domestically controlled qualified investment entity," and webelieve that we are and will remain a domestically controlled qualified investment entity, and that a sale of our stock should not be subject to taxation underFIRPTA. However, no assurance can be given that we are or will remain a domestically controlled qualified investment entity.

In the event that we are not a domestically controlled qualified investment entity, but our stock is "regularly traded," as defined by applicable Treasuryregulations, on an established securities market, a non-U.S. stockholder's sale of our common stock nonetheless also would not be subject to tax under FIRPTAas a sale of a USRPI, provided that the selling non-U.S. stockholder held 10% or less of our outstanding shares of our common stock any time during aprescribed testing period. Our common stock is, and we expect that it will continue to be, regularly traded on an established securities market.

If gain on the sale of our stock were subject to taxation under FIRPTA, the non-U.S. stockholder would be required to file a U.S. federal income tax returnand would be subject to the same treatment as a U.S. stockholder with respect to such gain, subject to applicable alternative minimum tax and a specialalternative minimum tax in the case of non-resident alien individuals. Moreover, in order to enforce the collection of the tax, the purchaser of the stock could berequired to withhold 15% of the purchase price and remit such amount to the IRS.

Gain from the sale of our stock that would not otherwise be subject to FIRPTA will nonetheless be taxable in the United States to a non-U.S. stockholder intwo cases: (i) if the non-U.S. stockholder's investment in our stock is effectively connected with a U.S. trade or business conducted by such non-U.S. stockholder,the non-U.S. stockholder will be subject to the same treatment as a U.S. stockholder with respect to such gain, except that a non-U.S. stockholder that is acorporation may also be subject to a branch profits tax at a rate of 30% (unless reduced or eliminated by treaty), or (ii) if the non-U.S. stockholder is anonresident alien individual who was present in the United States for 183 days or more during the taxable year and certain other requirements are met, thenonresident alien individual will be subject to a 30% tax on the individual's capital gain. In addition, even if we are a domestically controlled qualifiedinvestment entity, upon disposition of our stock, a non-U.S. stockholder may be treated as having gain from the sale or exchange of a USRPI if the non-U.S.

64

Table of Contents

stockholder (a) disposes of our common stock within a 30-day period preceding the ex-dividend date of a distribution, any portion of which, but for thedisposition, would have been treated as gain from the sale or exchange of a USRPI and (b) acquires, or enters into a contract or option to acquire, other shares ofour common stock within 30 days after such ex-dividend date.

Special FIRPTA Rules. Certain provisions under FIRPTA create certain exemptions from FIRPTA and otherwise modify the application of the foregoingFIRPTA rules for particular types of non-U.S. investors, including "qualified foreign pension funds" and their wholly owned foreign subsidiaries and certainwidely held, publicly traded "qualified collective investment vehicles." Non-U.S. stockholders are urged to consult their own tax advisors regarding theapplicability of these or any other special FIRPTA rules to their particular investment in our common stock.

Estate Tax. If our stock is owned or treated as owned by an individual who is not a citizen or resident (as specially defined for U.S. federal estate taxpurposes) of the United States at the time of such individual's death, the stock will be includable in the individual's gross estate for U.S. federal estate taxpurposes, unless an applicable estate tax treaty provides otherwise, and may therefore be subject to U.S. federal estate tax.

Non-U.S. stockholders are urged to consult their tax advisors regarding the U.S. federal, state, local and foreign income and other tax consequencesof owning and disposing of our stock.

Taxation of Tax-Exempt Stockholders

Tax-exempt entities, including qualified employee pension and profit sharing trusts and individual retirement accounts, generally are exempt from U.S.federal income taxation. However, they may be subject to taxation on their unrelated business taxable income ("UBTI"). While some investments in real estatemay generate UBTI, the IRS has ruled that dividend distributions from a REIT to a tax-exempt entity do not constitute UBTI. Based on that ruling, and providedthat (i) a tax-exempt stockholder has not held our stock as "debt financed property" within the meaning of the Code (i.e., where the acquisition or holding of theproperty is financed through a borrowing by the tax-exempt stockholder) and (ii) our stock is not otherwise used in an unrelated trade or business, distributionsthat we make and income from the sale of our stock generally should not give rise to UBTI to a tax-exempt stockholder.

Tax-exempt stockholders that are social clubs, voluntary employee benefit associations, supplemental unemployment benefit trusts, and qualified grouplegal services plans exempt from U.S. federal income taxation under Sections 501(c)(7), (c)(9), (c)(17) and (c)(20) of the Code are subject to different UBTIrules, which generally require such stockholders to characterize distributions that we make as UBTI.

In certain circumstances, a pension trust that owns more than 10% of our stock could be required to treat a percentage of any dividends received from us asUBTI if we are a "pension-held REIT." We will not be a pension-held REIT unless (i) we are required to "look through" one or more of our pension truststockholders in order to satisfy the REIT "closely held" test and (ii) either (a) one pension trust owns more than 25% of the value of our stock or (b) one or morepension trusts, each individually holding more than 10% of the value of our stock, collectively own more than 50% of the value of our stock. Certain restrictionson ownership and transfer of our stock generally should prevent a tax-exempt entity from owning more than 10% of the value of our stock and generally shouldprevent us from becoming a pension-held REIT.

Tax-exempt stockholders are urged to consult their tax advisors regarding the U.S. federal, state, local and foreign income and other taxconsequences of owning and disposing of our stock.

Other Tax Considerations

Legislative or Other Actions Affecting REITs

The present U.S. federal income tax treatment of REITs may be modified, possibly with retroactive effect, by legislative, judicial or administrative action atany time. The REIT rules are constantly under review by persons involved in the legislative process and by the IRS and the Treasury, which may result instatutory changes as well as revisions to regulations and interpretations. For example, the "Tax Cuts and Jobs Act" (the "Act") significantly changed the U.S.federal income tax laws applicable to businesses and their owners, including REITs and their shareholders. We cannot predict the long-term effect of the Act orany future law changes on REITs or their shareholders. Changes to the U.S. federal tax laws and interpretations thereof could adversely affect an investment inour common stock.

Medicare 3.8% Tax on Investment Income

Certain U.S. stockholders who are individuals, estates or trusts and whose income exceeds certain thresholds are required to pay a 3.8% Medicare tax ondividends and certain other investment income, including capital gains from the sale or other disposition of our common stock.

Foreign Account Tax Compliance Act

Sections 1471 to 1474 of the Code and existing guidance issued thereunder require withholding at a rate of 30% on dividends in respect of our commonstock held by or through certain foreign financial institutions (including investment funds), unless such institution enters into an agreement with the Treasury toreport, on an annual basis, information with respect to shares in the institution held by certain U.S. persons and by certain non-U.S. entities that are wholly orpartially owned by U.S. persons and to withhold on certain payments. Accordingly, the entity through which our common stock is held will affect thedetermination of whether such withholding is required. Similarly, dividends in respect of our common stock held by an investor that is a non-financial non-U.S.entity which does not qualify under certain exemptions will be subject to withholding at a rate of 30%, unless such entity either (i) certifies that such entity doesnot have any "substantial United States owners" or (ii) provides certain information regarding the entity's "substantial United States owners," which we or theapplicable withholding agent will in turn provide to the Secretary of the Treasury. An intergovernmental agreement between the United States and an applicableforeign country, or future Treasury regulations or other guidance, may modify these requirements. We will not pay any additional amounts to stockholders inrespect of any amounts withheld. Non-U.S. stockholders are encouraged to consult their tax advisors regarding the possible implications of these rules on theirinvestment in our common stock.

State, Local and Foreign Taxes

We and our subsidiaries and stockholders may be subject to state, local or foreign taxation in various jurisdictions including those in which we or theytransact business, own property or reside. Our state, local or foreign tax treatment and that of our stockholders may not conform to the U.S. federal income taxtreatment discussed above. Any foreign taxes that we incur do not pass through to stockholders as a credit against their U.S. federal income tax liability.Prospective investors should consult their tax advisors regarding the application and effect of state, local and foreign income and other tax laws on an investmentin our stock.

prospectus and the applicable prospectus supplement, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may usesecurities pledged by us or any selling securityholder or borrowed from us or any securityholder or others to settle those sales or to close out any related openborrowings of securities, and may use securities received from us or any selling securityholder in settlement of those derivative transactions to close out anyrelated open borrowings of securities. The third parties (or affiliates of such third parties) in such sale transactions by us or any selling securityholder will beunderwriters and will be identified in an applicable prospectus supplement (or a post-effective amendment). We may also sell securities under this prospectusupon the exercise of rights that may be issued to our securityholders.

We or any selling securityholder may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using thisprospectus and an applicable prospectus supplement. Such financial institution or third party may transfer its economic short position to investors in oursecurities or in connection with a simultaneous offering of other securities offered by this prospectus.

Underwriters, Agents and Dealers

If underwriters are used in the sale of our securities, the securities will be acquired by the underwriters for their own account and may be resold from time totime in one or more transactions described above. The securities may be offered to the public either through underwriting syndicates represented by managingunderwriters or directly by underwriters. Generally, the underwriters' obligations to purchase the securities will be subject to conditions precedent and theunderwriters will be obligated to purchase all of the securities if they purchase any of the securities. We may use underwriters with which we have a materialrelationship and will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

We or any selling securityholder may sell the securities through agents from time to time. When we or any selling securityholder sell securities throughagents, the prospectus supplement will name any agent involved in the offer or sale of securities and any commissions we or any selling securityholder pay tothem. Generally, any agent will be acting on a best efforts basis for the period of its appointment.

We or any selling securityholder may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase our securities from us orany selling securityholder at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment anddelivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectussupplement will set forth any commissions we or any selling securityholder pay for solicitation of these contracts.

Underwriters, dealers and agents may contract for or otherwise be entitled to indemnification by us against certain civil liabilities, including liabilities underthe Securities Act, or to contribution with respect to payments made by the underwriters, dealers or agents, under agreements between us or any sellingsecurityholders and the underwriters, dealers and agents.

We or any selling securityholder may grant underwriters who participate in the distribution of our securities an option to purchase additional securities tocover over-allotments, if any, in connection with the distribution.

Underwriters, dealers or agents may receive compensation in the form of discounts, concessions or commissions from us, any selling securityholders or ourpurchasers, as their agents in connection with the sale of our securities. These underwriters, dealers or agents may be considered to be underwriters under theSecurities Act. As a result, discounts, commissions or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discountsand commissions. The

68

Table of Contents

prospectus supplement for any securities offered by us or any selling securityholders will identify any such underwriter, dealer or agent and describe anycompensation received by them from us. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changedfrom time to time.

Any underwriter may engage in over-allotment transactions, stabilizing transactions, short-covering transactions and penalty bids in accordance withRegulation M under the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permitbids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short-covering transactions involve purchases of oursecurities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession froma dealer when the securities originally sold by the dealer are purchased in a transaction to cover short positions. Those activities may cause the price of thesecurities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. We make no representationor prediction as to the direction or magnitude of any effect these transactions may have on the price of our securities. For a description of these activities, see theinformation under the heading "Underwriting" in the applicable prospectus supplement.

Underwriters, broker-dealers or agents who may become involved in the sale of our securities may engage in transactions with and perform other servicesfor us for which they receive compensation.

Stabilization Activities

In connection with an offering through underwriters, an underwriter may, to the extent permitted by applicable rules and regulations, purchase and sellsecurities in the open market. These transactions, to the extent permitted by applicable rules and regulations, may include short sales, stabilizing transactions andpurchases to cover positions created by short sales. Short sales involve the sale by the underwriters of a greater number of securities than they are required topurchase in the offering. "Covered" short sales are sales made in an amount not greater than the underwriters' option to purchase additional securities from us inthe offering, if any. If the underwriters have an over-allotment option to purchase additional securities from us, the underwriters may consider, among otherthings, the price of securities available for purchase in the open market as compared to the price at which they may purchase securities through the over-allotmentoption. "Naked" short sales, which may be prohibited or restricted by applicable rules and regulations, are any sales in excess of such option or where theunderwriters do not have an over-allotment option. The underwriters must close out any naked short position by purchasing securities in the open market. Anaked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the securities in the openmarket after pricing that could adversely affect investors who purchase in the offering.

Accordingly, to cover these short sales positions or to otherwise stabilize or maintain the price of the securities, the underwriters may bid for or purchasesecurities in the open market and may impose penalty bids. If penalty bids are imposed, selling concessions allowed to syndicate members or other broker-dealersparticipating in the offering are reclaimed if securities previously distributed in the offering are repurchased, whether in connection with stabilization transactionsor otherwise. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevailin the open market. The imposition of a penalty bid may also affect the price of the securities to the extent that it discourages resale of the securities. Themagnitude or effect of any stabilization or other transactions is uncertain.

Direct Sales

We or any selling securityholder may also sell securities directly to one or more purchasers without using underwriters or agents. In this case, no agents,underwriters or dealers would be involved. We may sell securities upon the exercise of rights that we may issue to our securityholders. We or any sellingsecurityholder may also sell securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Actwith respect to any sale of those securities.

At-the-Market Offerings

To the extent that we make sales through one or more underwriters or agents in at-the-market offerings, we will do so pursuant to the terms of a sales agencyfinancing agreement or other at-the-market offering arrangement between us and the underwriters or agents. If we engage in at-the-market sales pursuant to anysuch agreement, we will issue and sell our securities through one or more underwriters or agents, which may act on an agency basis or on a principal basis.During the term of any such agreement, we may sell securities on a daily basis in exchange transactions or otherwise as we agree with the underwriters or agents.The agreement will provide that any securities sold will be sold at prices related to the then prevailing market prices for our securities. Therefore, exact figuresregarding proceeds that will be raised or commissions to be paid cannot be determined at this time. Pursuant to the terms of the agreement, we may agree to sell,and the relevant underwriters or agents may agree to solicit offers to purchase, blocks of our common stock or other securities. The terms of each such agreementwill be set forth in more detail in a prospectus supplement to this prospectus.

Trading Market and Listing of Securities

Any common stock sold pursuant to a prospectus supplement will be listed on the NASDAQ Global Select Market. The securities other than common stockmay or may not be listed on a national securities exchange. It is possible that one or more underwriters may make a market in a class or series of securities, butthe underwriters will not be obligated to do so and may discontinue any market making at any time without notice. We cannot give any assurance as to theliquidity of the trading market for any of the securities.

Item 14. Other Expenses of Issuance and Distribution

The following table itemizes the expenses incurred in connection with the issuance and registration of the securities being registered hereunder. All of theamounts shown are estimates.

Item 15. Indemnification of Directors and Officers

Insofar as the following provisions permit indemnification of directors, officers or persons controlling us for liability arising under the Securities Act, wehave been informed that, in the opinion of the U.S. Securities and Exchange Commission, this indemnification is against public policy as expressed in theSecurities Act and is therefore unenforceable.

Maryland Law

The following applies to CyrusOne Inc., CyrusOne Finance Corp. ("FinCo"), CyrusOne LP and CyrusOne GP.

Maryland law permits a Maryland corporation to include in its charter a provision limiting the liability of its directors and officers to the corporation and itsstockholders for money damages, except for liability resulting from (i) actual receipt of an improper benefit or profit in money, property or services or (ii) activeand deliberate dishonesty that is established by a final judgment and which is material to the cause of action. The charters of CyrusOne Inc. and FinCo eachcontain a provision that eliminates the liability of its respective directors and officers to the maximum extent permitted by Maryland law.

The MGCL requires a corporation (unless its charter provides otherwise, which the charters of CyrusOne Inc. and FinCo do not) to indemnify a director orofficer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he or she is made a party by reason of his or her service inthat capacity. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines,settlements and

reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of theirservice in those or other capacities unless it is established that:

• the act or omission of the director or officer was material to the matter giving rise to the proceeding and (1) was committed in bad faith or (2) wasthe result of active and deliberate dishonesty;

• the director or officer actually received an improper personal benefit in money, property or services; or

• in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful.

Under the MGCL, a Maryland corporation may not indemnify a director or officer in a suit by or in the right of the corporation in which the director orofficer was adjudged liable to the corporation or in a proceeding in which the director or officer was adjudged liable on the basis that personal benefit wasimproperly received. A court may order indemnification if it determines that the director or officer is fairly and reasonably entitled to indemnification, eventhough the director or officer did not meet the prescribed standard of conduct or was adjudged liable on the basis that personal benefit was improperly received.However, indemnification for an adverse judgment in a suit by or in the right of the corporation or for a judgment of liability on the basis that personal benefitwas improperly received, is limited to expenses.

In addition, the MGCL permits a Maryland corporation to advance reasonable expenses to a director or officer upon the corporation's receipt of:

• a written affirmation by the director or officer of his or her good faith belief that he or she has met the standard of conduct necessary forindemnification by the corporation; and

• a written undertaking by or on behalf of the director or officer to repay the amount paid or reimbursed by the corporation if it is ultimatelydetermined that the director or officer did not meet the standard of conduct.

CyrusOne Inc.'s charter authorizes it to obligate CyrusOne Inc., and CyrusOne Inc.'s bylaws obligate it, to the maximum extent permitted by Maryland lawin effect from time to time, to indemnify and, without requiring a preliminary determination of the ultimate entitlement to indemnification, pay or reimbursereasonable expenses in advance of final disposition of a proceeding to:

• any present or former director or officer of CyrusOne Inc. who is made or threatened to be made a party to, or witness in, a proceeding by reasonof his or her service in that capacity; or

• any individual who, while a director or officer of CyrusOne Inc. and at its request, serves or has served as a director, officer, partner, trustee,member or manager of another corporation, real estate investment trust, limited liability company, partnership, joint venture, trust, employeebenefit plan or any other enterprise and who is made or threatened to be made a party to the proceeding by reason of his or her service in thatcapacity.

CyrusOne Inc.'s charter and bylaws also permit it to indemnify and advance expenses to any person who served a predecessor of CyrusOne Inc. in any ofthe capacities described above and to any employee or agent of CyrusOne Inc. or a predecessor of CyrusOne Inc.

ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to:

FinCo's charter and bylaws also permit it to indemnify and advance expenses to any person who served a predecessor of FinCo in any of the capacitiesdescribed above and to any employee or agent of FinCo or a predecessor of FinCo.

Maryland Law permits a Maryland limited partnership to indemnify any partner, employee or agent from and against any and all claims whatsoever, exceptin the case of an action or failure to act by a partner that constitutes willful misconduct or recklessness, and subject to any standards or restrictions set forth in itspartnership agreement. The partnership agreement of CyrusOne LP provides that CyrusOne Inc., its directors, officers and employees, CyrusOne GP, as generalpartner, and its trustees, officers and employees, employees of our operating partnership and any other persons that the general partner may designate areindemnified to the fullest extent permitted by law, but that CyrusOne LP shall not indemnify any indemnitee for any liability (i) if it is established that the act oromission of the indemnitee constituted fraud, intentional harm or gross negligence on the part of the indemnitee, (ii) arising from an action or proceedinginitiated by the indemnitee (other than to enforce such indemnitee's rights to indemnification or advance of expenses) or (iii) with respect to any claim as towhich the indemnitee is found to be liable to CyrusOne LP.

CyrusOne GP's declaration of trust contains a provision that eliminates the liability of its trustees and officers to the maximum extent permitted by Marylandlaw, which limits the liability of trustees and officers to the same extent as described above for directors and officers of CyrusOne Inc. and FinCo. Maryland lawpermits a Maryland statutory trust to indemnify any trustee, officer, employee or agent against any and all claims or demands whatsoever. CyrusOne GP'sdeclaration of trust obligates it, to the maximum extent permitted by Maryland law in effect from time to time, to indemnify and, without requiring a preliminarydetermination of the ultimate entitlement to indemnification, pay or reimburse reasonable expenses in advance of final disposition of a proceeding to any presentor former trustee or officer of CyrusOne GP against any claim or liability to which such person may become subject by reason of such status, except for liabilityfor such person's gross negligence or intentional harm.

Re: Certain U.S. Federal Income Tax Matters Ladies and Gentlemen:

We have acted as special tax counsel to CyrusOne Inc., a Maryland corporation (“CyrusOne”), in connection with the filing by CyrusOneof a shelf registration statement on Form S-3 with the Securities and Exchange Commission, dated as of the date hereof (together with the prospectus filedtherewith, the “Registration Statement”) pursuant to which CyrusOne may offer, from time to time, debt securities of CyrusOne, CyrusOne LP and CyrusOneFinance Corp., and common stock, preferred stock, warrants, rights, and units of CyrusOne.

In connection with this opinion, we have examined and relied on originals or copies, certified or otherwise identified to our satisfaction, ofthe Registration Statement and such other documentation and information provided by you as we have deemed necessary or appropriate as a basis for theopinion set forth herein. In addition, you have provided us with, and we are relying upon, a certificate (the “Officers’ Certificate”) containing certain factualrepresentations and covenants of officers of CyrusOne, which relate to, among other things, the actual and proposed operation of CyrusOne and each of theentities in which CyrusOne holds or has held a direct or indirect interest (collectively, the “Company”). Although we are not aware of any facts inconsistentwith the statements, representations and covenants in the Officers’ Certificate, we have not made an independent investigation of all of the facts, statements,representations and covenants set forth in the Officers’ Certificate, the Registration Statement or in any other document. In particular, we note that theCompany may engage in transactions in connection with which we have not provided legal advice and have not reviewed, and of which we may be unaware.We have, consequently, assumed and relied on representations that the information presented in the Officers’ Certificate, the Registration Statement and otherdocuments, or otherwise furnished to us, accurately and completely describe all material facts with respect to the matters addressed in the

Officers’ Certificate. We have assumed that such statements, representations and covenants are true without regard to any qualification as to knowledge,belief, intent or materiality. Our opinion is conditioned on the continuing accuracy and completeness of such statements, representations and covenants. Anymaterial change or inaccuracy in the facts, statements, representations, and covenants referred to, set forth, or assumed herein or in the Officers’ Certificatemay affect our conclusions set forth herein.

In our review of certain documents in connection with our opinion as expressed below, we have assumed the legal capacity of all naturalpersons, the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of alldocuments submitted to us as certified, conformed, photostatic, or electronic copies, and the authenticity of the originals of such copies. Where documentshave been provided to us in draft form, we have assumed that the final executed versions of such documents will not differ materially from such drafts.

Our opinion is also based on the correctness of the following assumptions: (i) each of the entities comprising the Company has been andwill be operated in accordance with the laws of the jurisdiction in which it was formed and in the manner described in the relevant organizational documents,(ii) there will be no changes in the applicable laws of the State of Maryland or of any other state or jurisdiction under the laws of which any of the entitiescomprising the Company have been formed, and (iii) each of the written agreements to which the Company is a party has been and will be implemented,construed and enforced in accordance with its terms.

In rendering our opinion, we have considered and relied upon the Internal Revenue Code of 1986, as amended (the “Code”), the regulationspromulgated thereunder (the “Regulations”), administrative rulings and other interpretations of the Code and the Regulations by the courts and the InternalRevenue Service (“IRS”), all as they exist at the date hereof. It should be noted that the Code, the Regulations, judicial decisions, and administrativeinterpretations are subject to change or differing interpretation at any time and, in some circumstances, with retroactive effect. A material change that ismade after the date hereof in any of the foregoing bases for our opinion could affect our conclusions set forth herein. There can be no assurance, moreover,that our opinion will be accepted by the IRS or, if challenged, accepted by a court.

Based on the foregoing, we are of the opinion that, commencing with its taxable year ended on December 31, 2013, CyrusOne has beenorganized and has operated in conformity with the requirements for qualification and taxation as a real estate investment trust (“REIT”) under the Code, andits proposed method of operation will enable it to meet the requirements for qualification and taxation as a REIT under the Code.

As noted in the Registration Statement, CyrusOne’s qualification and taxation as a REIT depend upon its ability to meet, through actualoperating results,

2

certain requirements relating to the sources of its income, the nature of its assets, its distribution levels and the diversity of its stock ownership, and variousother qualification tests imposed under the Code, the results of which are not reviewed by us. Accordingly, no assurance can be given that the actual resultsof CyrusOne’s operation for any one taxable year will satisfy the requirements for taxation as a REIT under the Code.

Other than as expressly stated above, we express no opinion on any issue relating to CyrusOne or to any investment therein.

This opinion is expressed as of the date hereof, and we are under no obligation to supplement or revise our opinion to reflect any legaldevelopments or factual matters arising subsequent to the date hereof or the impact of any information, document, certificate, record, statement,representation, covenant or assumption relied upon herein that becomes incorrect or untrue.

We consent to the filing of this opinion as an exhibit to the Registration Statement and to the reference to Skadden, Arps, Slate, Meagher &Flom LLP under the headings “U.S. Federal Income Tax Considerations” and “Legal Matters” in the Registration Statement. In giving this consent, we donot thereby admit that we are in the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended, or the rules andregulations of the Securities and Exchange Commission.

Very truly yours,
