Explanation of Responses:

Id Content
F1 On January 6, 2025, the Reporting Person filed a Form 4 which inadvertently included an incorrect distribution type due to an administrative error. This amendment is being filed solely to reflect that the shares of phantom stock (the "Phantom Shares") were distributed in shares of Iron Mountain Incorporated common stock ("Common Stock") instead of in cash. Only whole shares of Common Stock were transferred in-kind; fractional shares were sold and settled in cash.
F2 Pursuant to the Reporting Person's election to participate in the Iron Mountain Incorporated Directors Deferred Compensation Plan (the "Plan"), the Phantom Shares will become payable in shares of Common Stock on various dates selected by the Reporting Person or as otherwise provided in the Plan. Each Phantom Share is the economic equivalent of one share of Common Stock.
F3 Settlement of the Phantom Shares is in Common Stock.
