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 2.88% dividend yield. Shareholders receive $3.3770 per share annually in quarterly payments, with the next ex-dividend date set for September 15, 2026. The stock carries a beta of 1.217, meaning it moves with more volatility than the broader market, which income investors focused on stability should weigh carefully.
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 covering secure document archiving, data center operations, and digital transformation services for over 225,000 clients globally, which supports recurring cash flows that REITs typically use to fund distributions beyond reported net income. Iron Mountain Incorporated dividend safety faces pressure from that 238.1% ratio, which sits well above levels most income investors consider sustainable on an earnings basis, and the dividend history does show at least one year-over-year decline in the available window.
Iron Mountain Incorporated dividend history shows a CAGR of 15.4% per year from 2010 to 2025. Per-share payments grew from $0.3750 to $3.2190 over that period (2026 data is partial and excluded from this calculation). The largest single-year jump in the window was 447.2% in 2012, though growth slowed considerably in later years, with 2020 through 2022 showing essentially flat payments around $2.47 per share.
| 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 stock fits dividend investors who prioritize yield over rapid income growth. The current yield of 2.88% sits in the moderate (2-4%) range and runs above the 5-year average of 2.29%, which means buyers today are locking in a historically elevated rate for this stock. The 15.4% long-term CAGR looks impressive on paper, but the growth story has cooled: payments barely moved between 2020 and 2022 before picking back up. The trade-off is clear. Iron Mountain Incorporated offers a meaningful yield backed by a global infrastructure of 1,450 facilities and a massive recurring client base, but the 238.1% payout ratio means the dividend rests on cash flow, not earnings coverage, and that limits the margin of safety income investors typically want.
