An estimated 18% now and 28% by the end of 2028, on METR's long-run pace at four in five, from the workforce Iron Mountain Incorporated's own annual report describes and BLS staffing patterns for its industries, never from a roster. It is an estimate with a stated method. It is not a forecast of jobs lost or of savings, and it says nothing about what the company will do.
How many people does Iron Mountain Incorporated employ?
29,400 as of December 31, 2025, as its annual report for the period ending December 31, 2025 states as the sum of the parts it gives. About 40% in the U.S.

What does Iron Mountain Incorporated's annual report say about AI?
14 sentences in the filing name AI. Its annual reports for fiscal 2021 to 2025 name it in 2, 2, 4, 6 and 14 sentences, year by year. They are counted and quoted on this page, never judged: a count says how much a filing talks about AI, not what the company does with it.
How is this estimated?
Claude Fable 5.1 read the annual report under the Index's written rubric (version 1) on October 3, 2026: the stated headcount, the share in the U.S. when stated, and the workforce as a blend of industry staffing patterns. The estimates are the site's industry estimates weighted by those shares, from O*NET tasks with estimated lengths and METR's measurements of how long a task AI models can finish. A company can write to info@stratussc.com to have its reading checked against its filing.
