Company snapshot — Iron Mountain Incorporated

IRM in five paragraphs: what it makes and sells, where it sits in the Closelook stack, who it is priced against, why we track it, what we watch. Research diary, not advice.

What it does
Iron Mountain stores and manages physical records and digital data for corporate customers worldwide, from paper archives to digital files. It also runs data centres and offers services that help organisations retire, recycle or resell used IT hardware. The company is structured as a specialty real estate investment trust and is based in Portsmouth, New Hampshire.
Where it sits in the stack
Iron Mountain has no seat in Closelook's Rubin or Halo build-out indices; within our wider universe it sits in the Real Estate sector, under the REIT - Specialty grouping, alongside other property-based businesses rather than the AI hardware or software layers.
Who it is priced against
Closelook's peer group carries no entry for Iron Mountain; the name the market sometimes sets beside it is Digital Realty, given the overlap in data-centre operations.
Why Closelook tracks it
Iron Mountain holds a seat in the S&P 500, the diary's broad-market reference index, but carries no seat in Rubin or Halo. It does not yet carry a Closelook score, and the diary has not quoted it in any edition so far.
What the diary watches
The diary watches whether Iron Mountain's data-centre and asset-lifecycle services grow to outweigh its traditional records-storage business, which would change how the company is read within its sector.
