Iron Mountain has executed Amendment No. 6 to its Credit Agreement dated June 18, 2025, implementing significant changes to its term loan structure. The amendment includes two key modifications: (1) a revised amortization schedule for existing 2022 Term A Loans, and (2) the addition of $286.7 million in incremental term loans.
Key financial details:
- Total outstanding Amended and Upsized 2022 Term A Loans: $500 million
- New quarterly amortization payments: 1.25% of the aggregate principal amount
- Proceeds from incremental term loans used to reduce revolving credit facility borrowings
The amendment maintains most other material provisions of the original Credit Agreement unchanged. JPMorgan Chase Bank serves as the administrative agent, with its Toronto Branch acting as Canadian administrative agent. This refinancing action suggests proactive management of the company's debt structure and liquidity position.
