About
Iron Mountain Incorporated is a global storage and information management services company that has evolved from a physical records storage business into a hybrid physical-and-digital infrastructure REIT, founded in 1951 by Herman Knaust in an abandoned iron ore mine in Livingston, New York, and now headquartered in Boston, Massachusetts, trading on NYSE (IRM). The company generated approximately $6.1 billion in revenues for FY2024 under CEO William Meaney, managing over 1,450 facilities across 60+ countries. Iron Mountain's physical Records Management segment—storing approximately 750 million cubic feet of physical records in its vast warehouse network and providing secure document destruction through Recall and SFG subsidiaries—generates highly predictable, recurring storage rental revenues from long-term contracts with corporations, healthcare providers, government agencies, and financial institutions obligated by regulatory retention requirements to preserve documents for decades.

CEO Sumit Roy leads Realty Income's strategy of growing the net lease portfolio through sale-leaseback transactions with operators seeking to unlock capital from owned real estate while maintaining long-term occupancy.
