| Fiscal year | FY2025 ended December 31, 2025 | FY2024 ended December 31, 2024 | FY2023 ended December 31, 2023 | FY2022 ended December 31, 2022 |
|---|---|---|---|---|
| Revenue | $6.9 billion | $6.1 billion | $5.5 billion | $5.1 billion |
| Operating income | $1.2 billion | $1.0 billion | $922 million | $1.0 billion |
| Operating margin | 16.9% | 16.4% | 16.8% | 20.6% |
| Net income | $152 million | $184 million | $187 million | $562 million |

| Operating cash flow | $1.3 billion | $1.2 billion | $1.1 billion | $928 million |
| Capital expenditures | $2.3 billion | $1.8 billion | $1.3 billion | $875 million |
| Free cash flow | -$932 million | -$595 million | -$226 million | $52 million |
Operating margin held roughly steady between fiscal 2024 and 2025, which separates pricing and cost discipline from revenue growth alone. Free cash flow (operating cash flow minus capital expenditures) was -$932 million against net income of $152 million; cash generation fell short of reported earnings, which is worth reconciling in the cash flow statement.

Where These Numbers Come From
Every figure on this page is a value Iron Mountain reported in its own SEC filings, read from the SEC's XBRL data (accession 0001020569-26-000013 for fiscal year 2025). Ratios are computed from those reported values. Figures were retrieved on October 7, 2026; a later amendment or a new annual report can change them, and the filing itself always takes precedence over this summary.
Each fiscal year is labeled by the calendar year in which it ended, so a company that names the same period differently in its own filings (many retailers whose year ends in January) may use another label. A year is left out of the table when the SEC data set holds no value for it. A figure shown as "Not reported" means the company did not file a value under the standard tag Swoopr reads, not that the amount was zero. This page is educational and describes reported history only; it is not a forecast or a recommendation.
