Is this normal for this company?
Each figure against the range this same company has produced recently. Neither end of a range is the good end.
Share price divided by the earnings actually reported over the four most recent quarters. The range is the same calculation at each of this company's last few results, so roughly the past year.
Profit as a share of sales, from the company's own quarterly statements. The range covers the 5 quarters we hold, and the figure shown is its most recent one.
How these ranges are built
Every number here is the company's own reported figure, not a comparison with other companies. The ranges come from this company's own results and its share price. Where it reports in a different currency from the one its shares trade in, the price-to-earnings range is left out rather than mixing the two.
What does Iron Mountain Incorporated do?

Does Iron Mountain Incorporated pay a dividend?
Yes - Iron Mountain Incorporated currently pays a dividend of about 2.8% a year, which is £28 a year for every £1,000 invested (the yearly payout as a share of the price). A dividend is a slice of profit handed to shareholders; the yield moves as the price moves, and a company can cut or stop it. An ISA doesn't shelter the US tax on this one →
What do the numbers say about Iron Mountain Incorporated's dividend?
There's no rating here, and we don't judge whether the dividend will continue - that would be advice. Here are the figures income investors usually look at, and what each one means, so you can weigh it up yourself.
Figures are from the latest available data and can be distorted by one-off results. Past payments don't predict future ones, and a dividend can be cut at any time. This lays out the numbers to help you understand them - it is not a view on what will happen.
Most recent ex-dividend date: 15 Jun 2026. To receive a dividend you must already own the shares before the ex-dividend date; become a holder on or after it and the previous owner keeps that payment. Why the price usually falls that morning →
What do Iron Mountain Incorporated's numbers mean?
How has it performed?
Growth of £1,000, the worst fall, and year by year
Over about 2 years to 2026-09-11. This is the share price only - reinvesting the dividends would add to it. And it's the USD return - as a UK investor your actual £ return also moves with the exchange rate. Past performance is not a guide to the future, and it could just as easily have fallen.
How much has Iron Mountain Incorporated actually fallen?
Over the last 2 years of daily prices, Iron Mountain Incorporated fell as much as −40% from a high to a later low. Falls like this are normal when you own a share.
Past falls are not a forecast - it can fall further, or recover.
How has it done year by year?
Calendar-year total return - the share price with dividends reinvested - from adjusted closing prices. The current year is only part-complete. Past returns are not a guide to the future.

What this does and doesn't tell you
This is a recent snapshot of the share register, and it moves. We don't read anything into who owns what - a high institutional share is common for any large listed company and is not a signal about it.
Based on beta - how much the price swings versus the whole market. Bumpier isn't bad; it just means a rougher ride, which matters more the sooner you might need the money.
Prices move on results, news and the mood of the whole market - no single headline explains a day, and a quiet week is usually just noise, not a signal.
How much money does Iron Mountain Incorporated make?
Revenue and profit by quarter, and how much of each sale turns into profit.
Where does each £100 of Iron Mountain Incorporated's sales go?
A rough split of the latest full-year figures: of every £100 of sales, about £46 covers making the product or service, £48 goes on running costs, tax and interest, and about £6 is left as profit. Margins vary a lot by industry, and one-off items can distort a single year.
