About Iron Mountain
Iron Mountain is a real estate investment trust built on records storage. It makes money storing and managing physical documents and information for businesses, a steady legacy franchise it has run for decades.
Its growth engine is different: a multi-gigawatt data center platform. Iron Mountain builds data center colocation capacity on land it already owns, leasing space, power, and cooling to companies that need somewhere to run their computing, including AI workloads.
Founded in 1951 and headquartered in Portsmouth, New Hampshire, Iron Mountain trades on the NYSE and employs about 29,400 people.
Iron Mountain in the AI buildout
Iron Mountain sits in the Data Centers & Hardware layer of the AI buildout. Its advantage is land: it is converting property it already owns into a multi-gigawatt data center colocation platform at a time when powered, permitted sites are scarce. Data centers are the growth story and the case for viewing the company differently than a records-storage REIT. The legacy storage business still dominates revenue, so its AI exposure is a growing minority of the whole.
IRM is tracked in Data Centers & Hardware, rated Growing on the AI Exposure leaderboard.
