RISK FACTORS

        Investing in our securities involves risk. You should carefully consider the risk factors incorporated by reference from our most recent Annual Report on Form 10-K, the information contained under the heading "Cautionary Note Regarding Forward-Looking Statements" in this prospectus or under any similar heading in any applicable prospectus supplement or in any document incorporated herein or therein by reference, any specific risk factors discussed under the caption "Risk Factors" in any applicable prospectus supplement or in any document incorporated herein or therein by reference and the other information contained in, or incorporated by reference in, this prospectus or any applicable prospectus supplement before making an investment decision. If any such risks occur, our business, financial condition or results of operations could be materially harmed, the market price of our securities could decline and you could lose all or part of your investment.


CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS

        We have made statements in this prospectus and the documents incorporated by reference herein that constitute "forward-looking statements" as that term is defined in the Private Securities Litigation Reform Act of 1995, other U.S. federal securities laws or "forward-looking information" as that term is defined under applicable securities laws in Canada (together, "forward-looking statements"). These forward-looking statements concern our operations, economic performance, financial condition, goals, beliefs, future growth strategies, investment objectives, plans and current expectations. These forward-looking statements are subject to various known and unknown risks, uncertainties and other factors. When we use words such as "believes," "expects," "anticipates," "estimates" or similar expressions, we are making forward-looking statements.

        Although we believe that our forward-looking statements are based on reasonable assumptions, our expected results may not be achieved, and actual results may differ materially from our expectations. In addition, important factors that could cause actual results to differ from expectations include, among others:

Table of Contents

Please read carefully the information under "Risk Factors" beginning on page 3.

        Other important factors that could cause actual results to differ materially from those in our forward-looking statements are described more fully in our most recently filed Annual Report on Form 10-K, including those described under the caption "Item 1A. Risk Factors," and other reports filed from time to time with the SEC and any prospectus supplement.

        These cautionary statements should not be construed by you to be exhaustive and they are made only as of the date of this prospectus. You should not rely upon forward-looking statements except as statements of our present intentions and of our present expectations, which may or may not occur. You should read these cautionary statements as being applicable to all forward-looking statements wherever they appear. Except as required by law, we undertake no obligation to release publicly the result of any revision to these forward-looking statements that may be made to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events. Readers are also urged to review carefully and consider the various disclosures we have made or incorporated by reference in this prospectus, as well as our other periodic reports filed with the SEC.


RATIO OF EARNINGS TO FIXED CHARGES

        The following table sets forth our consolidated ratio of earnings to fixed charges for the periods indicated:

 
  Year Ended December 31,  
 
  2011   2012   2013   2014   2015  

Ratio of Earnings to Fixed Charges

    2.2x     1.9x     1.5x     1.7x     1.5x  

        The ratios of earnings to fixed charges presented above were computed by dividing our earnings by fixed charges. For this purpose, earnings have been calculated by adding fixed charges to income (loss) from continuing operations before provision for income taxes. Fixed charges consist of interest costs, the interest component of rental expense and amortization of debt discounts and deferred financing costs, but do not include interest expense related to uncertain tax positions. We did not have any shares of preferred stock outstanding during any of the periods presented above, and therefore our ratios of earnings to combined fixed charges and preferred stock dividends are the same as the ratios of earnings to fixed charges presented above.


USE OF PROCEEDS

        Unless otherwise described in a prospectus supplement, we intend to use the net proceeds from the sale of any securities covered by this prospectus for general corporate purposes, which may include acquisitions, investments and the repayment of indebtedness outstanding at a particular time. Until we apply the proceeds from a sale of the securities covered by this prospectus for their stated purposes, we may invest those proceeds in short-term investments, including repurchase agreements, some or all or which may not be investment grade.

The applicable prospectus supplement will describe the specific terms of the debt securities and guarantees of the debt securities offered through that prospectus supplement.

Table of Contents

        In addition, Wells Fargo Bank, National Association, is a trustee under certain indentures of the Debt Issuers and may be named as trustee in any senior subordinated indenture or subordinated indenture or applicable prospectus supplements. Iron Mountain also has banking relationships with Wells Fargo Bank, National Association or its affiliates in the ordinary course of business.


DESCRIPTION OF IRON MOUNTAIN CAPITAL STOCK

        As used in this section, "we", "us" or "our" refers to Iron Mountain, and not any of its subsidiaries.

        The description below summarizes the more important terms of Iron Mountain's capital stock. We have previously filed with the SEC copies of our certificate of incorporation and bylaws. See "Where You Can Find More Information." You should refer to those documents for the complete terms of our capital stock. This summary is subject to and qualified by reference to the description of the particular terms of your securities described in the applicable prospectus supplement.

General

        Iron Mountain's authorized capital stock consists of 400,000,000 shares of common stock, par value $0.01 per share, or the Common Stock, and 10,000,000 shares of preferred stock, par value $0.01 per share, or the Preferred Stock, as of February 29, 2016.

Preferred Stock

        The following is a summary of the general terms and provisions of the Preferred Stock that we may offer by this prospectus. The applicable prospectus supplement will describe the specific terms of the Preferred Stock offered through that prospectus supplement. We will file a copy of the certificate of designations that contains the terms of each new series of Preferred Stock with the SEC each time we issue a new series of Preferred Stock, and these certificates of designations will be incorporated by reference into the registration statement of which this prospectus is a part. Each certificate of designations will establish the number of shares included in a designated series and fix the designation, powers, privileges, preferences and rights of the shares of such series as well as any applicable qualifications, limitations or restrictions. A holder of Preferred Stock should refer to the applicable

Table of Contents

certificate of designations, our certificate of incorporation and the applicable prospectus supplement for more specific information.

        Our board of directors has been authorized, subject to limitations provided in our certificate of incorporation, to provide for the issuance of shares of Preferred Stock in multiple series. No shares of Preferred Stock are currently outstanding.

        With respect to each series of Preferred Stock, our board of directors has the authority to fix the following terms:

        Holders of Preferred Stock will not have preemptive rights with respect to shares of Preferred Stock. In addition, rights with respect to shares of Preferred Stock will be subordinate to the rights of our general creditors. If we receive the appropriate payment, shares of Preferred Stock that we issue will be fully paid and nonassessable.

        As described under "Description of Iron Mountain Depositary Shares," we may, at our option, elect to offer depositary shares evidenced by depositary receipts. If we elect to do this, each depositary receipt will represent a fractional interest in a share of the particular series of the Preferred Stock issued and deposited with a depositary. The applicable prospectus supplement will specify that fractional interest.

        We currently plan to use Computershare Shareowner Services LLC as the registrar and transfer agent for any series of Preferred Stock.

Common Stock

        All outstanding shares of Common Stock are validly issued, fully paid and non-assessable. Under Delaware General Corporation Law, or DGCL, stockholders generally are not personally liable for a corporation's acts or debts.

        Voting Rights.    Holders of Common Stock are entitled to one vote per share on each matter to be decided by our stockholders, subject to the rights of holders of any series of Preferred Stock that may be outstanding from time to time. Pursuant to our certificate of incorporation, there are no cumulative voting rights in the election of directors. In an uncontested election of directors, each director shall be elected by the affirmative vote of holders of a majority of the votes cast. In a contested election, the directors shall be elected by a plurality of the votes of shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors.

        Dividend Rights and Limitations.    Holders of Common Stock will be entitled to receive ratably any dividends or distributions that our board of directors may declare from time to time out of funds legally available for this purpose.

7


Table of Contents

        Dividends and other distributions on Common Stock are also subject to the rights of holders of any series of Preferred Stock that may be outstanding from time to time and to the restrictions in our credit agreement and indentures. See "—Preferred Stock."

        Liquidation Rights.    In the event of liquidation, dissolution or winding up of our affairs, after payment or provision for payment of all of our debts and obligations and any preferential distributions to holders of shares of Preferred Stock, if any, the holders of Common Stock will be entitled to share ratably in our remaining assets available for distribution.

        Miscellaneous.    Our board of directors has the power to issue shares of authorized but unissued Common Stock without further stockholder action. The issuance of these unissued shares could have the effect of diluting the earnings per share and book value per share of currently outstanding shares of Common Stock. The holders of Common Stock have no preemptive, subscription, redemption or conversion rights.

        Reference is made to the applicable prospectus supplement relating to the Common Stock offered by that prospectus supplement for specific terms, including:

        Transfer Agent and Registrar.    The transfer agent and registrar for Common Stock is Computershare Shareowner Services LLC, 250 Royall Street, Canton, Massachusetts 02021. Its telephone number is (781) 575-2000.

Restrictions on Ownership and Transfer

        To facilitate compliance with the ownership limitations applicable to a REIT under the Internal Revenue Code of 1986, as amended, or the Code, our certificate of incorporation contains restrictions on the ownership and transfer of our stock.

        These ownership and transfer restrictions could delay, defer or prevent a transaction or a change in control that might involve a premium price for our Common Stock or otherwise be in the best interest of our stockholders. All certificates representing shares of capital stock bear legends describing or referring to these restrictions.

        For us to qualify as a REIT under the Code, our stock must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months or during a proportionate part of a shorter taxable year (other than the first year for which an election to be a REIT has been made). Also, not more 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 to include certain entities such as private foundations) during the last half of a taxable year (other than the first taxable year for which an election to be a REIT has been made). To facilitate compliance with these ownership requirements and other requirements for continued qualification as a REIT and to otherwise protect us from the consequences of a concentration of ownership among our stockholders, our certificate of incorporation contains provisions restricting the ownership or transfer of shares of stock.

        The relevant sections of our certificate of incorporation provide that, subject to the exceptions and the constructive ownership rules described below, no person (as defined in our certificate of incorporation) may beneficially or constructively own more than 9.8% in value of the aggregate of outstanding shares of stock, including Common Stock and Preferred Stock, or more than 9.8% in value or number (whichever is more restrictive) of the outstanding shares of any class or series of stock. We refer to these restrictions as the "ownership limits."

8


Table of Contents

        The applicable constructive ownership rules under the Code are complex and may cause stock owned actually or constructively by an individual or entity to be treated as owned by another individual or entity. As a result, the acquisition of less than 9.8% in value of outstanding stock or less than 9.8% in value or number of outstanding shares of any class or series of stock (including through the acquisition of an interest in an entity that owns, actually or constructively, any class or series of stock) by an individual or entity could nevertheless cause that individual or entity, or another individual or entity, to own, constructively or beneficially, in excess of 9.8% in value of outstanding stock or 9.8% in value or number of outstanding shares of any class or series of stock.

        In addition to the ownership limits, our certificate of incorporation prohibits any person from actually or constructively owning shares of stock to the extent that such ownership would cause any of our income that would otherwise qualify as "rents from real property" for purposes of Section 856(d) of the Code to fail to qualify as such.

        Our board of directors has in the past granted ownership limitation waivers and may, in its sole discretion, in the future grant such a waiver to a person, exempting them from the ownership limits and certain other REIT limits on ownership and transfer of stock described above, and may establish a different limit on ownership for any such person. However, our board of directors may not grant a waiver exempting any person whose ownership of outstanding stock in violation of these limits would result in our failing to qualify as a REIT. In order to be considered by our board of directors for an ownership limitation waiver or a different limit on ownership, a person must make such representations and undertakings as are reasonably necessary to ascertain that such person's beneficial or constructive ownership of stock will not now or in the future jeopardize our ability to qualify as a REIT under the Code and must generally agree that any violation or attempted violation of such representations or undertakings (or other action that is contrary to the ownership limits and certain other REIT limits on ownership and transfer of stock described above) will result in the shares of stock being automatically transferred to a trust as described below. As a condition of its waiver, our board of directors may require an opinion of counsel or Internal Revenue Service ruling satisfactory to our board of directors with respect to our qualification as a REIT and may impose such other conditions as it deems appropriate in connection with the granting of the waiver or a different limit on ownership.

        In connection with the waiver of the ownership limits or at any other time, our board of directors may from time to time increase the ownership limits for one or more persons and decrease the ownership limits for all other persons; provided that the new ownership limits may not, after giving effect to such increase and under certain assumptions stated in our certificate of incorporation, result in us being "closely held" within the meaning of Section 856(h) of the Code (without regard to whether the ownership interests are held during the last half of a taxable year). Reduced ownership limits will not apply to any person whose percentage ownership of total shares of stock or of the shares of a class or series of stock, as applicable, is in excess of such decreased ownership limits until such time as such person's percentage of total shares of stock or of the shares of a class or series of stock, as applicable, equals or falls below the decreased ownership limits, but any further acquisition of stock in excess of such percentage will be in violation of the ownership limits.

        Our certificate of incorporation further prohibits:

9


Table of Contents

        The foregoing provisions on transferability and ownership will not apply if our board of directors determines that it is no longer in our best interests to attempt to qualify, or to continue to qualify, as a REIT.

        Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares of stock that will or may violate the ownership limits or any of the other foregoing restrictions on transferability and ownership will be required to give notice to us immediately (or, in the case of a proposed or attempted transaction, at least 15 days prior to such transaction) and provide us with such other information as we may request in order to determine the effect, if any, of such transfer on our qualification as a REIT.

        Pursuant to our certificate of incorporation, if there is any purported transfer of our stock or other event or change of circumstances that, if effective or otherwise, would violate any of the restrictions described above, then the number of shares causing the violation (rounded up to the nearest whole share) will be automatically transferred to a trust for the exclusive benefit of a designated charitable beneficiary, except that any transfer that results in the violation of the restriction relating to our stock being beneficially owned by fewer than 100 persons will be automatically void and of no force or effect. The automatic transfer will be effective as of the close of business on the business day prior to the date of the purported transfer or other event or change of circumstances that requires the transfer to the trust. We refer below to the person that would have owned the shares if they had not been transferred to the trust as the purported transferee. Any ordinary dividend paid to the purported transferee, prior to our discovery that the shares had been automatically transferred to a trust as described above, must be repaid to a trustee designated in accordance with our certificate of incorporation upon demand. Our certificate of incorporation also provides for adjustments to the entitlement to receive extraordinary dividends and other distributions as between the purported transferee and the trust. If the transfer to the trust as described above is not automatically effective, for any reason, to prevent violation of the applicable restriction contained in our certificate of incorporation, then the transfer of the excess shares will be automatically void and of no force or effect.

        Shares of our stock transferred to the trustee are deemed to be offered for sale to us or our designee at a price per share equal to the lesser of (i) the price per share in the transaction that resulted in such transfer to the trust or, if the purported transferee did not give value for the shares in connection with the event causing the shares to be held in trust (e.g., in the case of a gift, devise or other such transaction), the market price at the time of such event and (ii) the market price on the date we accept, or our designee accepts, such offer. We have the right to accept such offer until the trustee has sold the shares of our stock held in the trust pursuant to the clauses described below. Upon a sale to us, the interest of the charitable beneficiary in the shares sold terminates and the trustee must distribute the net proceeds of the sale to the purported transferee, except that the trustee may reduce the amount payable to the purported transferee by the amount of any ordinary dividends that we paid to the purported transferee prior to our discovery that the shares had been transferred to the trust and that is owed by the purported transferee to the trustee as described above. Any net sales proceeds and extraordinary dividends in excess of the amount payable to the purported transferee shall be immediately paid to the charitable beneficiary, and any ordinary dividends held by the trustee with respect to such stock will be promptly paid to the charitable beneficiary.

        If we do not buy the shares, the trustee must, as soon as reasonably practicable (and, if the shares are listed on a national securities exchange, within 20 days) after receiving notice from us of the transfer of shares to the trust, sell the shares to a person or entity who could own the shares without violating the restrictions described above. Upon such a sale, the trustee must distribute to the purported transferee an amount equal to the lesser of (i) the price paid by the purported transferee for the shares or, if the purported transferee did not give value for the shares in connection with the event causing the shares to be held in trust (e.g., in the case of a gift, devise or other such transaction), the market price of the shares on the day of the event causing the shares to be held in the trust, and

10


Table of Contents

(ii) the sales proceeds (net of commissions and other expenses of sale) received by the trustee for the shares. The trustee may reduce the amount payable to the purported transferee by the amount of any ordinary dividends that we paid to the purported transferee before our discovery that the shares had been transferred to the trust and that is owed by the purported transferee to the trustee as described above. Any net sales proceeds in excess of the amount payable to the purported transferee will be immediately paid to the charitable beneficiary, together with any ordinary dividends held by the trustee with respect to such stock. In addition, if prior to discovery by us that shares of our stock have been transferred to a trust, such shares of stock are sold by a purported transferee, then such shares will be deemed to have been sold on behalf of the trust and, to the extent that the purported transferee received an amount for or in respect of such shares that exceeds the amount that such purported transferee was entitled to receive as described above, such excess amount shall be paid to the trustee upon demand. The purported transferee has no rights in the shares held by the trustee.

        The trustee will be indemnified by us or from the proceeds of sales of stock in the trust for its costs and expenses reasonably incurred in connection with conducting its duties and satisfying its obligations under our certificate of incorporation. The trustee will also be entitled to reasonable compensation for services provided as determined by agreement between the trustee and the board of directors, which compensation may be funded by us or the trust. If we pay any such indemnification or compensation, we are entitled on a first priority basis (subject to the trustee's indemnification and compensation rights) to be reimbursed from the trust. To the extent the trust funds any such indemnification and compensation, the amounts available for payment to a purported transferee (or the charitable beneficiary) would be reduced.

        The trustee will be designated by us and must be unaffiliated with us and with any purported transferee. Prior to the sale of any shares by the trust, the trustee will receive, in trust for the beneficiary, all distributions paid by us with respect to the shares, and may also exercise all voting rights with respect to the shares.

        Subject to the DGCL effective as of the date that the shares have been transferred to the trust, the trustee will have the authority, at the trustee's sole discretion:

However, if we have already taken corporate action, then the trustee may not rescind and recast the vote.

        In addition, if the board of directors determines that a proposed or purported transfer would violate the restrictions on ownership and transfer of our stock set forth in our certificate of incorporation, the board of directors may take such action as it deems advisable to refuse to give effect to or to prevent such violation, including but not limited to, causing us to repurchase shares of our stock, refusing to give effect to the transfer on our books or instituting proceedings to enjoin the transfer.

        From time to time, at our request, every person that is an owner of 5% or more (or such lower percentage as required by the Code or the Treasury regulations thereunder) of the outstanding shares of any class or series of our stock, must provide us written notice of its name and address, the number of shares of each class and series of our stock that the person beneficially owns and a description of the manner in which the shares are held. Each such owner must also provide us with such additional information as we may request in order to determine the effect, if any, of such owner's beneficial ownership on our qualification as a REIT and to ensure compliance with the ownership limits. In addition, each beneficial owner or constructive owner of our stock, and any person (including the

11


Table of Contents

stockholder of record) who is holding shares of our stock for a beneficial owner or constructive owner will, upon demand, be required to provide us with such information as we may request in good faith in order to determine our qualification as a REIT and to comply with the requirements of any taxing authority or governmental authority or to determine such compliance.


DESCRIPTION OF IRON MOUNTAIN DEPOSITARY SHARES

General

        As used in this section, "we", "us" or "our" refers to Iron Mountain, and not any of its subsidiaries.

        The following is a summary of the material provisions of any deposit agreement and of the depositary shares and depositary receipts representing depositary shares. Because it is a summary, it does not contain all of the information that may be important to you. If you want more information, you should read the form of deposit agreement and depositary receipts which will be filed as exhibits to the registration statement of which this prospectus is a part prior to an offering of depositary shares. See "Where You Can Find More Information." This summary is also subject to and qualified by reference to the descriptions of the particular terms of our securities described in the applicable prospectus supplement. If indicated in a prospectus supplement, the terms of such securities may differ from those described below.

        We may, at our option, elect to offer fractional interests in shares of Preferred Stock, rather than whole shares of Preferred Stock. If we exercise this option, we will appoint a depositary to issue depositary receipts representing those fractional interests. Preferred Stock of each series represented by depositary shares will be deposited under a separate deposit agreement between us and the depositary. The prospectus supplement relating to a series of depositary shares will show the name and address of the depositary. Subject to the terms of the applicable deposit agreement, each owner of depositary shares will be entitled to all of the distribution, voting, conversion, redemption, liquidation and other rights and preferences of the Preferred Stock represented by those depositary shares.

        Depositary receipts issued pursuant to the applicable deposit agreement will evidence ownership of depositary shares. Upon surrender of depositary receipts at the office of the depositary, and upon payment of the charges provided in and subject to the terms of the deposit agreement, a holder of depositary shares will be entitled to receive the shares of Preferred Stock underlying the surrendered depositary receipts.

Distributions

        The depositary will be required to distribute all cash distributions received in respect of the applicable Preferred Stock to the record holders of depositary receipts evidencing the related depositary shares in proportion to the number of depositary receipts owned by such holders on the relevant record date, which will be the same date as the record date fixed by us for the distribution paid on the applicable series of Preferred Stock.

        If the distribution is other than in cash, a depositary will be required to distribute property received by it to the record holders of depositary receipts entitled thereto, unless the depositary determines that it is not feasible to make the distribution. In that case, the depositary may, with our approval, sell the property and distribute the net proceeds from the sale to the holders.

        Depositary shares that represent shares of Preferred Stock converted or exchanged will not be entitled to distributions. The deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights we offer to holders of the Preferred Stock will be made available to holders of depositary shares. All distributions will be subject to obligations of holders to

12


Table of Contents

file proofs, certificates and other information and to pay certain charges and expenses to the depositary.

Withdrawal of Shares of Preferred Stock

        You may receive the number of whole shares of Preferred Stock and any money or other property represented by your depositary receipts after surrendering the depositary receipts at the corporate trust office of the depositary. Partial shares of Preferred Stock will not be issued. If the depositary receipts that you surrender exceed the number of depositary shares that represent the number of whole shares of Preferred Stock you wish to withdraw, then the depositary will deliver to you at the same time a new depositary receipt evidencing the excess number of depositary shares. Once you have withdrawn your shares of Preferred Stock, you will not be entitled to re-deposit those shares of Preferred Stock under the deposit agreement in order to receive depositary shares. We do not expect that there will be any public trading market for withdrawn shares of Preferred Stock.

Redemption of Depositary Shares

        If we redeem a series of the Preferred Stock underlying the depositary shares, the depositary will redeem those shares from the proceeds received by it. The depositary will mail notice of redemption not less than 30 and not more than 60 days before the date fixed for redemption to the record holders of the depositary receipts evidencing the depositary shares we are redeeming at their addresses appearing in the depositary's books. The redemption price per depositary share will be equal to the applicable fraction of the redemption price per share payable with respect to the series of the Preferred Stock. The redemption date for depositary shares will be the same as that of the Preferred Stock. If we are redeeming less than all of the depositary shares, the depositary will select the depositary shares we are redeeming by lot or pro rata as the depositary may determine.

        After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed outstanding. All rights of the holders of the depositary shares and the related depositary receipts will cease at that time, except the right to receive the money or other property to which the holders of depositary shares were entitled upon redemption. Receipt of the money or other property is subject to surrender to the depositary of the depositary receipts evidencing the redeemed depositary shares.

Voting of the Preferred Stock

        Upon receipt of notice of any meeting at which the holders of the applicable Preferred Stock are entitled to vote, a depositary will be required to mail the information contained in the notice of meeting to the record holders of the applicable depositary receipts. Each record holder of depositary receipts on the record date, which will be the same date as the record date for the Preferred Stock, will be entitled to instruct the depositary as to the exercise of the voting rights pertaining to the amount of Preferred Stock represented by the holder's depositary shares. If you do not instruct the depositary how to vote your shares, the depositary will abstain from voting those shares. The depositary will not be responsible for any failure to carry out an instruction to vote or for the effect of any such vote made so long as the action or inaction of the depositary is in good faith and is not the result of the depositary's gross negligence or willful misconduct.

Liquidation Preference

        Upon our liquidation, whether voluntary or involuntary, each holder of depositary shares will be entitled to the fraction of the liquidation preference accorded each share of Preferred Stock represented by the depositary shares, as described in the applicable prospectus supplement.

13


Table of Contents

Conversion or Exchange of Shares of Preferred Stock

        The depositary shares will not themselves be convertible into or exchangeable for Common Stock, Preferred Stock or any of our other securities or property. Nevertheless, if so specified in the applicable prospectus supplement, the depositary receipts may be surrendered by holders to the applicable depositary with written instructions to it to instruct us to cause conversion or exchange of the Preferred Stock represented by the depositary shares. Similarly, if so specified in the applicable prospectus supplement, we may require you to surrender all of your depositary receipts to the applicable depositary upon our requiring the conversion or exchange of the Preferred Stock represented by the depositary shares. We will agree that, upon receipt of the instruction and any amounts payable in connection with the conversion or exchange, we will cause the conversion or exchange using the same procedures as those provided for delivery of Preferred Stock to effect the conversion or exchange. If you are converting or exchanging only a part of the depositary shares, the depositary will issue you a new depositary receipt for any unconverted or unexchanged depositary shares.

Amendment and Termination of a Deposit Agreement

        We and the applicable depositary are permitted to amend the provisions of the depositary receipts and the deposit agreement. However, the holders of at least a majority of the applicable depositary shares then outstanding must approve any amendment that adds or increases fees or materially and adversely alters the rights of holders. Every holder of an outstanding depositary receipt at the time any amendment becomes effective, by continuing to hold the receipt, will be bound by the applicable deposit agreement, as amended.

        Any deposit agreement may be terminated by us upon not less than 30 days' prior written notice to the applicable depositary if a majority of each series of Preferred Stock affected by the termination consents to the termination. When a deposit agreement is terminated, the depositary will be required to deliver or make available to each holder of depositary receipts, upon surrender of the depositary receipts held by the holder, the number of whole or fractional shares of Preferred Stock as are represented by the depositary shares evidenced by the depositary receipts, together with any other property held by the depositary with respect to the depositary shares. In addition, a deposit agreement will automatically terminate if:

Charges of a Depositary

        We will pay all transfer and other taxes and governmental charges arising solely from the existence of a deposit agreement. In addition, we will pay the fees and expenses of a depositary in connection with the initial deposit of the shares of Preferred Stock and any redemption of the shares of Preferred Stock. However, holders of depositary receipts will pay any transfer taxes or other governmental charges and the fees and expenses of the depositary, including any duties the holders request to be performed that are outside of those expressly provided for in the applicable deposit agreement.

Resignation and Removal of Depositary

        A depositary may resign at any time by delivering to us notice of its election to do so. In addition, we may at any time remove a depositary. Any resignation or removal will take effect when we appoint

14


Table of Contents

a successor depositary and it accepts the appointment. We must appoint a successor depositary within 60 days after delivery of the notice of resignation or removal. A depositary must be a bank or trust company having its principal office in the United States that has a combined capital and surplus of at least $50 million.

Miscellaneous

        The depositary will be required to forward to holders of depositary receipts any reports and communications from us that it receives with respect to the related Preferred Stock. Holders of depositary receipts will be able to inspect the transfer books of the depositary and the list of holders of depositary receipts upon reasonable notice.

        Neither we nor the depositary will be liable if the depositary is prevented from or delayed in performing its obligations under a deposit agreement by law or any circumstances beyond its control. Our obligations and those of the depositary under a deposit agreement will be limited to performing duties in good faith and without gross negligence or willful misconduct. Neither we nor the depositary will be obligated to prosecute or defend any legal proceeding in respect of any depositary receipts, depositary shares or related Preferred Stock unless satisfactory indemnity is furnished. We and the depositary will be permitted to rely on written advice of counsel or accountants, on information provided by persons presenting Preferred Stock for deposit, by holders of depositary receipts or by other persons believed in good faith to be competent to give the information, and on documents believed in good faith to be genuine and signed by a proper party.

        If the depositary receives conflicting claims, requests or instructions from any holders of depositary receipts, on the one hand, and us, on the other hand, the depositary shall be entitled to act on the claims, requests or instructions received from us.

DESCRIPTION OF IRON MOUNTAIN WARRANTS

        As used in this section, "we", "us" or "our" refers to Iron Mountain, and not any of its subsidiaries.

If you want more information, you should read the forms of warrants and the warrant agreement which will be filed as exhibits to the registration statement of which this prospectus is a part. See "Where You Can Find More Information." This summary is also subject to and qualified by reference to the descriptions of the particular terms of our securities described in the applicable prospectus supplement. If indicated in a prospectus supplement, the terms of such securities may differ from those described below.

        We may issue, together with any other securities being offered or separately, warrants entitling the holder to purchase from or sell to us, or to receive from us the cash value of the right to purchase or sell, debt securities, shares of Preferred Stock, depositary shares or shares of Common Stock. We and a warrant agent will enter a warrant agreement pursuant to which the warrants will be issued. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants. We will file a copy of the forms of warrants and the warrant agreement with the SEC at or before the time of the offering of the applicable series of warrants.

        In the case of each series of warrants, the applicable prospectus supplement will describe the terms of the warrants being offered thereby. These include the following, if applicable:

DESCRIPTION OF THE STOCK PURCHASE CONTRACTS
AND THE STOCK PURCHASE UNITS

        As used in this section, "we", "us" or "our" refers to Iron Mountain, and not any of its subsidiaries.

16


Table of Contents

        We may issue contracts obligating holders to purchase from us, and us to sell to the holders, a specified number of shares of Common Stock at a future date or dates, which we refer to herein as "stock purchase contracts." The price per share of Common Stock and the number of shares of Common Stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula set forth in the stock purchase contracts. The stock purchase contracts may be issued separately or as part of units consisting of a stock purchase contract and debt securities or debt obligations of third parties, including U.S. treasury securities, which secure the holders' obligations to purchase the Common Stock under the stock purchase contracts. We refer to these units herein as "stock purchase units." The stock purchase contracts may require holders to secure their obligations thereunder in a specified manner. The stock purchase contracts also may require us to make periodic payments to the holders of the stock purchase units or vice versa, and such payments may be unsecured or refunded on some basis.

        The applicable prospectus supplement will describe the terms of the stock purchase contracts or stock purchase units. The description in the applicable prospectus supplement will not necessarily be complete, and reference will be made to the stock purchase contracts, and, if applicable, collateral or depositary arrangements, relating to the stock purchase contracts or stock purchase units. If material, we will discuss in the applicable prospectus supplement U.S. federal income tax considerations applicable to the stock purchase units and the stock purchase contracts offered by such prospectus supplement.


DESCRIPTION OF CERTAIN PROVISIONS OF DELAWARE LAW AND
IRON MOUNTAIN'S CERTIFICATE OF INCORPORATION AND BYLAWS

        As used in this section, "we", "us" or "our" refers to Iron Mountain, and not any of its subsidiaries.

        Iron Mountain is organized as a Delaware corporation. The following is a summary of our certificate of incorporation and bylaws and certain provisions of Delaware law, in each case as currently in effect. Because it is a summary, it does not contain all the information that may be important to you. If you want more information, you should read our entire certificate of incorporation and bylaws, copies of which we have previously filed with the SEC, see "Where You Can Find More Information," or refer to the provisions of Delaware law.

        Delaware law, our certificate of incorporation and our bylaws contain some provisions that could delay or make more difficult the acquisition of us by means of a tender offer, a proxy contest or otherwise. These provisions, as described below, are expected to discourage certain types of coercive takeover practices and inadequate takeover bids and to encourage persons seeking to acquire control of us first to negotiate with us. We believe that the benefits of increased protection of our ability to negotiate with the proponent of an unfriendly or unsolicited proposal to acquire or restructure us outweigh the disadvantages of discouraging such proposals because, among other things, negotiations with respect to such proposals could result in an improvement of their terms.

Section 203 of The Delaware General Corporation Law

        We are subject to Section 203 of the DGCL. Subject to specific exceptions, Section 203 prohibits a publicly held Delaware corporation from engaging in a "business combination" with an "interested stockholder" for a period of three years after the time the person became an interested stockholder, unless:

17


Table of Contents

        "Business combinations" include mergers, asset sales and other transactions resulting in a financial benefit to the interested stockholder. Subject to various exceptions, in general an "interested stockholder" is a person that, together with his or her affiliates and associates, owns, or within three years did own, 15% or more of our outstanding voting stock.

Other Provisions of Our Certificate of Incorporation and Bylaws

        Our bylaws provide that a vacancy on the board of directors, including a vacancy created by an increase in the size of the board of directors by the directors, may be filled by a majority of the remaining directors, or by a sole remaining director, or by the stockholders, and each person so elected shall be a director to serve for the balance of the unexpired term of the directors. In addition, our bylaws provide that, in an uncontested election of directors, each director shall be elected by a majority of the votes cast by the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. In a contested election, the directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors. Under the DGCL, any director or the entire board of directors may be removed, with or without cause, by the holders of a majority of the shares then entitled to vote at the election of directors.

        Our bylaws also provide that a majority of votes cast by the shares present in person or represented by proxy at any meeting of stockholders and entitled to vote thereat shall decide any question (other than the election of directors) brought before such meeting, except in any case where a larger vote is required by the DGCL, our certificate of incorporation, our bylaws or otherwise.

        Certain other provisions of our certificate of incorporation and bylaws could have the effect of preventing or delaying any change in control of us, including:

        These provisions and statutory anti-takeover provisions could make it more difficult for a third party to acquire, or discourage a third party from seeking to acquire, control of us.

        In addition, our bylaws designate the Court of Chancery of the State of Delaware as the sole and exclusive forum for the adjudication of certain disputes involving us, including, without limitation, any derivative action or proceeding brought on behalf of us.

18


Table of Contents

        Our certificate of incorporation includes provisions eliminating the personal liability of our directors to the fullest extent permitted by the DGCL, and our bylaws include provisions indemnifying our directors and officers to the fullest extent permitted by the DGCL. The limitation of liability and indemnification provisions in our certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though a derivative action, if successful, might otherwise benefit us and our stockholders. In addition, the value of investments in our securities may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

        The organizational documents and the DGCL provide similar indemnification for the officers and directors of certain of the Subsidiary Guarantors.


PLAN OF DISTRIBUTION

        We may sell the securities under this prospectus from time to time, in one or more of the following ways:

        If we use underwriters or dealers in the sale, the securities will be acquired by the underwriters or dealers for their own account and may be resold from time to time in one or more transactions, including:

        We, and our underwriters, dealers or agents, reserve the right to accept or reject all or part of any proposed purchase of the securities. We will set forth in a prospectus supplement and pricing supplement, if any, the terms and offering of securities, including:

19


Table of Contents

        We may enter into derivative transactions with third parties or sell securities not covered by this prospectus to third parties in privately negotiated transactions from time to time. If the applicable prospectus supplement or pricing supplement, if any, indicates, in connection with those derivative transactions, such third parties (or affiliates of such third parties) may sell securities covered by this prospectus, the applicable prospectus supplement and pricing supplement, if any, including in short sale transactions. If so, such third parties (or affiliates of such third parties) may use securities pledged by us or borrowed from us or others to settle those sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative transactions to close out any related open borrowings of securities. The third parties (or affiliates of such third parties) in such sale transactions will be underwriters and will be identified in an applicable prospectus supplement (or a post-effective amendment).

        We may loan or pledge securities to a financial institution or other third party that in turn may sell the securities using this prospectus, an applicable prospectus supplement and an applicable pricing supplement, if any. Such financial institution or third party may transfer its economic short position to investors in our securities 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 to time in one or more transactions described above. The securities may be offered to the public either through underwriting syndicates represented by managing underwriters or directly by underwriters. Generally, the underwriters' obligations to purchase the securities will be subject to conditions precedent and the underwriters 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 material relationship. We will describe in the prospectus supplement, naming the underwriter, the nature of any such relationship.

        We may authorize underwriters, dealers or agents to solicit offers by certain purchasers to purchase our securities from us at the public offering price set forth in the prospectus supplement pursuant to delayed delivery contracts providing for payment and delivery on a specified date in the future. The contracts will be subject only to those conditions set forth in the prospectus supplement, and the prospectus supplement will set forth any commissions we 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 under the Securities Act, or to contribution with respect to payments made by the underwriters, dealers or agents, under agreements between us and the underwriters, dealers and agents.

        We may grant underwriters who participate in the distribution of our securities an option to purchase additional securities to cover 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 or our purchasers, as their agents in connection with the sale of our securities. These underwriters, dealers or agents may be considered to be underwriters under the Securities Act. As a result, discounts, commissions or profits on resale received by the underwriters, dealers or agents may be treated as underwriting discounts and commissions. The prospectus supplement will identify any such underwriter, dealer or agent and describe any compensation received by them from us. Any public offering price and any discounts or concessions allowed or re-allowed or paid to dealers may be changed from time to time.

20


Table of Contents

        Any underwriter may engage in over-allotment transactions, stabilizing transactions, short-covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934, as amended, or the Exchange Act. Over-allotment involves sales in excess of the offering size, which create a short position. Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum. Short-covering transactions involve purchases of our securities in the open market after the distribution is completed to cover short positions. Penalty bids permit the underwriters to reclaim a selling concession from a 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 the securities to be higher than it would otherwise be. If commenced, the underwriters may discontinue any of the activities at any time. We make no representation or 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 the information 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 services for us for which they receive compensation.

        Direct Sales.    We 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 holders of our securities. We may also sell the securities directly to institutional investors or others who may be deemed to be underwriters within the meaning of the Securities Act with respect to any sale of those securities.

        Trading Market and Listing of Securities.    We will make applications to list any shares of Common Stock sold pursuant to a supplement to this prospectus on the NYSE. We have not determined whether we will list any of the other securities we may offer on any national exchange or over-the-counter market, and any such listing will be disclosed in the applicable prospectus supplement. It is possible that one or more underwriters may make a market in a class or series of securities, but the 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 the liquidity of the trading market for any of the securities.

Item 15.    Indemnification of Directors and Officers

Iron Mountain Incorporated

Delaware Corporate Law

        Iron Mountain is a Delaware corporation. Section 102 of the DGCL permits a corporation to include a provision in its certificate of incorporation eliminating or limiting the personal liability of a director to a corporation or its stockholders for monetary damages for certain breaches of the director's fiduciary duty, except (1) for any breach of the director's duty of loyalty to the corporation or its stockholders, (2) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) the payment of unlawful dividends or unlawful stock repurchases or redemptions or (4) transactions from which the director received an improper personal benefit. Iron Mountain's certificate of incorporation eliminates the liability of directors to the fullest extent permissible under Delaware law.

        Section 145 of the DGCL, or Section 145, authorizes a corporation to indemnify its directors, officers, employees and agents against certain liabilities (including attorneys' fees, judgments, fines and expenses) they may incur in connection with specified actions, suits or proceedings, whether civil, criminal, administrative or investigative (other than an action by or in the right of the corporation, or a derivative action), if they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had no reasonable cause to believe their conduct was unlawful. Section 145 also provides that such persons have a right to indemnification against expenses where they have been successful on the merits or otherwise in defense of such actions. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys' fees) incurred in connection with defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. Section 145 empowers a corporation to purchase and maintain insurance on behalf of any

II-1


Table of Contents

directors, officers, employees and agents, against any liability asserted against such person and incurred by such person in any such capacity, whether or not the corporation would have the power to indemnify such person against such liability under Section 145.

        Section 145 provides that the indemnification provided thereby is not exclusive of any other indemnification rights that may exist under any bylaw, agreement, vote of stockholders or disinterested directors, or otherwise.

Iron Mountain's Certificate of Incorporation and Bylaws

        Iron Mountain's certificate of incorporation includes provisions eliminating the personal liability of its directors to the fullest extent permitted by Delaware Corporate Law, and Iron Mountain's bylaws include provisions indemnifying its directors and officers to the fullest extent permitted by Delaware Corporate Law. The limitation of liability and indemnification provisions in Iron Mountain's certificate of incorporation and bylaws may discourage stockholders from bringing a lawsuit against directors for breach of their fiduciary duty. These provisions may also have the effect of reducing the likelihood of derivative litigation against directors and officers, even though a derivative action, if successful, might otherwise benefit Iron Mountain and its stockholders. In addition, the value of investments in its securities may be adversely affected to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

        Article 12 of Iron Mountain's bylaws provides indemnification to directors and officers for all actions taken by them and for all failures to take action to the fullest extent permitted by Delaware law against all expense, liability and loss reasonably incurred or suffered by them in connection with any threatened, pending or completed action, suit or proceeding (including, without limitation, an action, suit or proceeding by or in the right of Iron Mountain), whether civil, criminal, administrative or investigative. Article 12 also permits Iron Mountain, by action of its board of directors, to indemnify employees and other agents of Iron Mountain to the same extent as directors and officers. Amendments, repeals or modifications of Article 12 can only be prospective and no such change may reduce the limitations of director's liability or limit indemnification or advancement of expenses unless adopted by the unanimous vote of all of the directors then serving or the affirmative vote of the holders of a majority of the outstanding shares of stock of Iron Mountain entitled to vote in elections of directors. Article 12 further permits Iron Mountain to maintain insurance, at its expense, for the benefit of any person on behalf of whom insurance is permitted to be purchased by Delaware law against any such expenses, liability or loss.

        Under Delaware law, directors of Iron Mountain will remain liable for the following:

        Iron Mountain maintains directors' and officers' liability insurance which would indemnify its directors and officers against damages arising out of certain kinds of claims which might be made against them based on their negligent acts or omissions while acting in their capacity as such.

        Reference is made to Iron Mountain's certificate of incorporation, as filed with the Secretary of State of the State of Delaware on June 26, 2014, as corrected by the Certificate of Correction of Iron Mountain filed with the Secretary of State of the State of Delaware on June 30, 2014, included as Annex B-1 to Iron Mountain's Proxy Statement for the Special Meeting of Stockholders of Iron

Mountain Incorporated, filed with the SEC on December 23, 2014 (File No. 001-13045). Reference is also made to Iron Mountain's Bylaws, included as Exhibit 3.3 to Iron Mountain's Annual Report on Form 10-K for the year ended December 31, 2014.

The Canadian Issuer

        Part 20 of the Canadian Issuer's articles of association, or Part 20, provides that, subject to the Business Corporations Act (British Columbia), or the BCBCA, the Canadian Issuer must indemnify a director or former director of the Canadian Issuer, or an Eligible Party, and his or her heirs and legal personal representatives against all judgments, penalties or fines awarded or imposed in, or an amount paid in settlement of, a legal proceeding or investigative action (current, threatened, pending or completed) in which such person is or may be joined as a party or liable, by reason of the Eligible Party being or having been a director of the Canadian Issuer. The Canadian Issuer must, after the final disposition of the eligible proceeding, pay the expenses actually and reasonably incurred by such person in respect of that proceeding. Part 20 specifies that each director is deemed to have contracted with the Canadian Issuer on the terms of this indemnity.

        Part 20 provides that subject to the BCBCA, the Canadian Issuer may indemnify any person. The failure of a director or officer to comply with the BCBCA or the Canadian Issuer's articles of association does not invalidate any indemnity to which he or she is entitled under Part 20. Part 20 further permits the Canadian Issuer to purchase and maintain insurance for the benefit of certain specified persons, including directors and officers, against any liability incurred by such persons.

        The foregoing provisions are generally consistent with Sections 160, 161 and 165 of the BCBCA, and Section 164 of the BCBCA contemplates court-ordered indemnification. Section 163(1) of the BCBCA prohibits indemnification if (1) in relation to the subject matter of the eligible proceeding, the Eligible Party did not act honestly and in good faith with a view to the best interests of the Canadian Issuer or an associated corporation or (2) in the case of an eligible proceeding other than a civil proceeding, the Eligible Party did not have reasonable grounds for believing that their conduct in respect of which the proceeding was brought was lawful. Pursuant to Section 163(2) of the BCBCA, the Canadian Issuer cannot indemnify, or pay the expenses of, an Eligible Party in respect of a proceeding brought against such Eligible Party by or on behalf of the Canadian Issuer or an associated corporation.

Table of Contents

        (b)   The undersigned registrants hereby undertake that, for purposes of determining any liability under the Securities Act of 1933, each filing of Iron Mountain's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

        (c)   Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by a director, officer or controlling person of the registrants in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

        (d)   Each of the undersigned registrants hereby undertakes to file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act of 1939, or the Act, in accordance with the rules and regulations prescribed by the Commission under Section 305(b)(2) of the Act.
