Iron Mountain Incorporated dividend income comes from one of the world's largest storage and information management companies, trusted by more than 225,000 organizations across roughly 50 countries. IRM currently pays a 3.02% dividend yield, with a trailing annual rate of $3.4560 per share paid quarterly. The next ex-dividend date is September 15, 2026, with the most recent quarterly payment of $0.8640 per share. A beta of 1.204 means IRM stock moves more than the broader market, so this is not a low-volatility income play.
Iron Mountain Incorporated pays out 238.1% of earnings as dividends, a payout ratio classified as high (above 75%). As a specialty REIT, IRM generates revenue from long-term contracts with over 225,000 clients storing critical records, digital assets, and sensitive documents across 1,450 facilities globally, which provides a recurring demand base that supports the payout despite the elevated ratio. Iron Mountain Incorporated dividend safety is the central concern here: a payout ratio this far above 100% means the dividend is not covered by net earnings, and any meaningful contraction in fee-based revenue or occupancy across its 90 million square feet of physical infrastructure would put the distribution under pressure.
Iron Mountain Incorporated dividend history shows a CAGR of 16.0% per year from 2010 to 2025. Per-share payments grew from $0.3483 to $3.2190 over that period (2026 data is partial and excluded from this calculation, per Iron Mountain Incorporated dividend 2026 reporting conventions for REITs). The largest annual increase in the window was 446.9% in 2012, though the history also contains at least one year-over-year decline exceeding 5%, so the growth path has not been linear.
| Period | CAGR | From | To |
|---|---|---|---|
| 3-Year | +9.2% | $2.47 (2022) | $3.22 (2025) |
| 5-Year | +5.4% | $2.47 (2020) | $3.22 (2025) |
| 10-Year | +5.4% | $1.91 (2015) | $3.22 (2025) |
IRM fits dividend investors who want above-average long-term dividend growth from a business with deep client entrenchment across physical and digital storage. The current yield of 3.02% is moderate (2-4%), and it sits above the 5-year average of 2.35%, which means income buyers are getting more yield than the stock has historically offered. The trade-off is a payout ratio of 238.1%, which is well above what earnings alone can cover, making the dividend dependent on the durability of Iron Mountain Incorporated's recurring revenue streams. Fast historical growth and a rising yield are the draws; the stretched payout ratio is the risk an investor accepts.
