If you held common stock of Iron Mountain in your name at any time during 2015, an IRS Form 1099-DIV will be provided to you by Computershare, Iron Mountain's transfer agent. If you held shares in "street name" during 2015, the IRS form provided by your bank, brokerage firm or nominee may report only the gross distributions paid to you. Therefore, you may need the information included in this press release to properly complete your federal tax return.

This information has been prepared using the best available information to date. Iron Mountain's federal income tax return for the year ended December 31, 2015 has not yet been filed. Please note that federal tax laws affect taxpayers differently, and we cannot advise you on how distributions should be reported on your federal income tax return. Please also note that state and local taxation of REIT distributions vary and may not be the same as the federal rules. Stockholders are encouraged to consult with their tax advisors as to the specific tax treatment of the distributions they received from us.
