BOSTON -- August 22, 2013

Iron Mountain Incorporated (NYSE: IRM), the storage and information management
company, today announced that, pursuant to its previously announced tender
offer (the “Tender Offer”) to purchase for cash up to $137.5 million (the
“Maximum Repurchase Amount”) aggregate principal amount of outstanding 8-3/8%
Senior Subordinated Notes due 2021 (CUSIP No. 46284P AM6) (the “Notes”), a
total of approximately $306.3 million principal amount of Notes (the “Tendered
Notes”) were validly tendered by 5:00 p.m., New York City time, on August 21,
2013 (the “Early Tender Deadline”). The Tender Offer is being made on the
terms and subject to the conditions set forth in the Offer to Purchase, dated
August 8, 2013 (the “Offer to Purchase”), and the related Letter of
Transmittal (“Letter of Transmittal”).

Since the Tendered Notes exceed the Maximum Repurchase Amount, the Tendered
Notes will be subject to proration in accordance with the terms of the Offer
to Purchase. The proration factor will be approximately 45%, and with regard
to any particular holder subject to rounding down to the nearest integral
multiple of $1,000. Iron Mountain will pay the total consideration of
$1,097.50 per $1,000 principal amount of Notes accepted for purchase in the
Tender Offer, which includes an early tender premium payment of $30 per $1,000
principal amount of Notes. Iron Mountain expects to make payment today for the
Notes accepted for purchase and will fund its payment obligation for such
Notes with a portion of the proceeds from its offering of $600 million in
aggregate principal amount of its 6% USD Senior Notes due 2023, which were
issued on August 13, 2013. Iron Mountain does not expect to accept for payment
any additional tenders of Notes after the Early Tender Deadline.
