Id Content
F1 Pursuant to the Reporting Person's election to participate in the Iron Mountain Incorporated Directors Deferred Compensation Plan with respect to certain restricted stock units ("RSUs") received on May 12, 2021, which RSUs vest on the grant date, the shares of phantom stock (the "Phantom Shares") will become payable in shares of Iron Mountain Incorporated common stock ("Common Stock") following the Reporting Person's disability or cessation of service as a director. Each Phantom Share is the economic equivalent of one share of Common Stock
F2 The amount of Phantom Shares beneficially owned was incorrectly disclosed due to a calculation error. This amendment corrects the number of beneficially owned shares following the reported transaction from 63,518.9549 to 68,700.7898.
