You probably know Iron Mountain as those big white trucks and the massive underground bunkers where your lawyer sends old boxes of paper to die. For decades, that was basically the whole story. But if you’re looking at iron mountain incorporated stock today, you’re not just buying a physical storage company anymore. Honestly, the shift happening under the hood is wild.
The company is halfway through a massive identity crisis—the good kind. They call it "Project Matterhorn." It’s basically their master plan to stop being "the box guys" and start being "the data guys." And looking at the numbers from early 2026, it seems like the pivot is actually working.
The 2026 Dividend Bump and Why It Matters
Let’s talk about the money first. Iron Mountain (IRM) isn’t just a regular stock; it’s a Real Estate Investment Trust (REIT). Because of that, they’re legally required to pay out at least 90% of their taxable income to shareholders.
Just this month, in January 2026, the company followed through on a promised 10% dividend hike. This isn't a one-off fluke. It's the fourth year in a row they've bumped the payout. We're looking at a quarterly dividend of $0.864 per share now. If you've been holding the stock for a while, that yield on cost is starting to look pretty juicy.
But why are they raising it? Usually, companies raise dividends when they have nowhere else to put the cash. That’s not the case here. They are spending billions—literally billions—on building out data centers. The fact that they can hike the dividend while also building a massive digital empire is a tightrope walk that's actually impressing Wall Street.
The Numbers You Actually Care About
- Current Dividend: $0.864 per quarter (effective Jan 2026).
- Data Center Growth: Management is forecasting 25%+ revenue growth in the data center segment for the rest of 2026.
- Customer Loyalty: They still boast a 98% retention rate. Once you put your data or boxes in the Mountain, you basically never leave.
Iron Mountain Incorporated Stock: More Than Just Cardboard Boxes
If you look at the Q3 and Q4 results leading into this year, a weird pattern emerged. The physical storage business—the one with the boxes—is still growing, but only at a mid-single-digit pace. It’s the "boring" foundation. It’s predictable. It’s the cash cow that funds all the crazy new stuff.
The real engine now is the Global Data Center business.
Iron Mountain currently operates 30 data centers across the globe. They aren't just small server rooms, either. We’re talking about massive facilities in Northern Virginia, London, and Phoenix. They recently signed a 36-megawatt lease for an entire site in Chicago. That’s massive. When a single lease can move the needle that much, you know the scale is shifting.
The Asset Lifecycle Management (ALM) Sleeper Hit
There is this other part of the business called ALM that most people sort of ignore. Basically, when a giant company like Google or JPMorgan finishes with their old servers, they can't just throw them in a dumpster. They need someone to securely wipe the data and recycle the hardware.
Iron Mountain bought a company called Regency Technologies to supercharge this. In 2025, this segment grew over 60%. It’s a $30 billion market that’s mostly fragmented, and Iron Mountain is basically trying to eat the whole thing.
What Most People Get Wrong About the Risks
Okay, so it sounds like a slam dunk, right? Not quite. There’s a reason the stock can be volatile.
First off, there’s the debt. Building data centers is incredibly expensive. You have to buy the land, secure the power (which is getting harder and harder with the AI boom), and build the cooling infrastructure. As of late 2025, their net debt was sitting around $15 billion.
Now, they’ve managed to get their leverage down to about 5.0x, which is the lowest it’s been in a decade. But still, $15 billion is a big number. If interest rates stay higher for longer than expected, servicing that debt eats into the money they could be giving you in dividends.
The AI Wildcard
Everyone is talking about AI. For iron mountain incorporated stock, AI is a double-edged sword. On one hand, AI needs massive amounts of data center space, which Iron Mountain provides. On the other hand, AI makes it easier for companies to digitize their old paper records.
If every company suddenly decides to scan every box they have in storage and then shred the paper, Iron Mountain loses that steady "box rent" they’ve relied on for 50 years. They are trying to get ahead of this by being the ones who do the scanning—like that massive $714 million contract they won with the U.S. Treasury—but it’s a transition that has to be timed perfectly.
Is the Valuation Realistic or Just Hype?
Right now, analysts like those at Truist and JPMorgan are leaning bullish, with price targets often hovering in the $110 to $120 range. But let's be real: the stock has had a massive run.

Some valuation models, like a Discounted Cash Flow (DCF), suggest the stock could be worth way more—some estimates go as high as $200—if you assume their data center growth continues at this breakneck pace for ten years. But that's a big "if."
The price-to-sales ratio is around 3.7x. Compare that to other specialized REITs that trade at 5x or 6x, and you could argue it's still "cheap." But you have to decide if you’re buying a slow-growth storage company or a high-growth tech play. The market is currently trying to price it as both.
How to Actually Play This
If you're looking at adding this to your portfolio, you've gotta decide what your goal is.
Are you an income seeker? The 3.8% to 4% yield is solid, and the history of raises is a good sign. But it’s not the 7% yield you might find in some riskier mortgage REITs. You’re trading a bit of yield for the "growth" potential of the data centers.

If you’re a growth investor, you’re betting on "Project Matterhorn." You’re betting that CEO William Meaney can successfully turn this tanker around before the physical storage business starts to fade.
Actionable Insights for Investors
- Watch the "Backlog": Iron Mountain often reports how many megawatts of data center space are "pre-leased." This is basically guaranteed future revenue. If this number starts to dip, the growth story is in trouble.
- Monitor the Treasury Contract: The $714 million deal with the U.S. Treasury is a huge test. If they execute this well, it’s a signal to every other government agency that Iron Mountain is the go-to for digital transformation.
- Check the Payout Ratio: They want to keep the dividend payout in the "low 60s" as a percentage of Adjusted Funds From Operations (AFFO). If that ratio creeps up toward 80% or 90%, the dividend growth will probably stall.
- Don't Ignore the "Old" Business: Physical storage still makes up the majority of their revenue. A sudden drop in organic storage volume would be a massive red flag, even if data centers are booming.
Basically, Iron Mountain is a hybrid beast. It has the safety of a 1950s storage business and the upside of a 2026 tech company. It’s a weird mix, but in a market that's obsessed with data and AI, it’s a mix that's currently winning. Just keep a close eye on that debt pile—it's the only thing that could really trip them up in the long run.
Start by looking into their most recent 10-K filing to see the specific breakdown of their $15.4 billion debt maturity schedule. If most of that debt is fixed-rate and long-term, the interest rate risk is much lower than the headlines might suggest. From there, compare their "Lease-up" rates in the data center segment against competitors like Equinix or Digital Realty to see if they are actually gaining market share or just riding the tide.
