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.
