Dividend Snapshot
Key Metrics
Current Yield
3.00%
At the Sep 14, 2026 price
The annual dividend as a percentage of the share price. A 3% yield is about $3 of dividends a year for every $100 invested at today's price.Annualized Dividend
$3.4560
The most recent payment scaled to a full year by how often it's paid. A $0.25 quarterly dividend annualizes to $1.00.Frequency
Q Quarterly
How often the dividend is paid: Q = quarterly (4x a year), M = monthly, S = semi-annual, A = annual.Rank Score
50.1
As of Sep 14, 2026
Our 0-100 house score blending yield quality, payout sustainability (the trailing-twelve-month payout ratio), profitability (TTM return on equity), valuation (TTM price-to-book) and payment reliability, recomputed daily. Higher means a stronger profile on those factors in our model — a research score, not advice or a recommendation to buy.RSI (14)
42
As of Sep 14, 2026
Relative Strength Index (0-100), a price-momentum gauge. Above 70 is often called 'overbought', below 30 'oversold'. A technical signal, not a dividend metric.52-Week Range
$78.86 – $133.06
Closes through Sep 11, 2026
The lowest and highest price over the past year — shows where today's price sits in its recent range.Payout Ratio (TTM)
238.12% (EPS-based)
12 months to Jun 30, 2026 (Q2 FY2026)
The share of earnings paid out as dividends over the trailing twelve months (TTM): dividends paid divided by net income across the company's four most recent reported quarters, dated by the latest quarter end. A fiscal-year tag such as FY2025 means only annual figures were available. Lower leaves more cushion; above 100% means paying out more than the company earned. It shows n/a for funds and when net income over the period was negative; for REITs and BDCs it is marked EPS-based, since they are judged on FFO/AFFO or net investment income instead.Years Paying

Quote & Key Data
Dividend Growth
Why the Yield Moved (90 Days)
IRM's dividend yield rose from 2.70% to 3.00% over the past ~90 days (+0.30 pp). Of that move, +0.00 pp came from changes in the dividend rate and +0.30 pp from the share price ($128.21 on Jun 16, 2026 → $115.18 on Sep 14, 2026). A yield that rises because the price fell is not an improvement in the payout itself.
Yield vs Its Own History
Across 333 daily observations over the past 16 months (through Sep 11, 2026), IRM's current yield is higher than approximately 32% of them. Our stored price history for IRM covers the past 16 months; 3- and 5-year averages are not yet computable from it and are deliberately not shown.
