Timing note: Iron Mountain’s official announcement schedules the Q2 release before the market opens Wednesday, August 5, 2026, followed by the conference call at 8:30 a.m. Eastern Time that same day. That is today, not tomorrow. This preview reflects information available before the Q2 results were published.
Iron Mountain enters the quarter with substantial momentum—and correspondingly high expectations.
Q1 revenue, adjusted EBITDA, and AFFO each grew approximately 22%, while organic revenue growth reached 17%, its highest rate in more than 25 years. Management raised full-year guidance and said it expected data-center leasing to finish “meaningfully” above its initial 100-megawatt target.
Investors have rewarded that execution. IRM closed August 4 at $125.54, up approximately 51% from January 2. At that price, the shares trade around 21.6 times the midpoint of management’s 2026 AFFO-per-share guidance and yield approximately 2.8% on the current annualized dividend.
That valuation changes the earnings hurdle. Merely meeting Q2 guidance may not be enough; the market will probably look for another beat, stronger leasing disclosures, and at least a modest increase in the full-year outlook.
The most relevant benchmarks are management’s own Q2 projections:
| Metric | Q2 2026 guidance | Q2 2025 actual | Implied growth |
|---|---|---|---|
| Revenue | Approximately $1.965B | $1.712B | ~15% |
| Adjusted EBITDA | Approximately $715M | $628M | ~14% |
| AFFO | Approximately $418M | $370M | ~13% |
| AFFO per share | Approximately $1.40 | $1.24 | ~13% |
Compared with Q1, the guidance implies modest sequential growth in revenue and EBITDA but a small decline in AFFO:
| Metric | Q1 2026 actual | Q2 guidance |
|---|---|---|
| Revenue | $1.936B | ~$1.965B |
| Adjusted EBITDA | $708M | ~$715M |
| EBITDA margin | 36.6% | ~36.4% implied |
| AFFO | $426M | ~$418M |
| AFFO/share | $1.43 | ~$1.40 |
A result close to those numbers would still represent strong year-over-year growth. But following Q1’s large outperformance, investors will likely judge the quarter against expectations for continued upside rather than against the prior-year comparison alone.
The data-center business is now the most important driver of IRM’s growth narrative.
In Q1:
The key question is not simply whether revenue grew again. Investors need evidence that leasing is keeping pace with the development pipeline.
Watch for:
A large leasing quarter with maintained returns would reinforce the view that IRM can grow into its substantial data-center capital program. Weak leasing—or vague language around expected contract timing—would be the clearest threat to the premium valuation.
Asset lifecycle management was Q1’s standout:
Some of that strength reflected favorable pricing for recovered memory and other components. Management said component prices had stabilized around levels contemplated in its original guidance, while the remaining increase in the ALM outlook was expected to come primarily from volume, enterprise expansion and data-center decommissioning.
That distinction is crucial. Investors should separate:
Watch for:
Strong volume with stable margins would support another ALM guidance increase. Revenue upside driven mostly by component prices would be lower quality.
The legacy records-management business remains essential because it supplies recurring revenue, high margins and customer relationships that IRM can use to cross-sell digital, ALM and data-center services.
Q1 Global RIM revenue grew 12% on a reported basis and 8% organically. Storage revenue grew 6% organically, and Global RIM adjusted EBITDA margin was approximately 44%. Management also said the physical records-storage business was on track for its 38th consecutive year of organic storage-rental growth.
Q2 faces a somewhat more difficult pricing comparison because the full effect of last year’s revenue-management actions appeared in the second quarter. Management nevertheless expected full-year pricing actions to remain around the “mid-single-digit-plus” level.
Watch for:
A healthy outcome would be continued mid-single-digit-plus organic storage growth with stable or improving margins. Material slowing here would matter because it would weaken the cash-generating foundation funding IRM’s newer businesses.
Digital Solutions grew more than 20% in Q1, supported by digitization projects and IRM’s AI-enabled DXP platform. The public sector is becoming a potentially meaningful source of additional growth.
For the large U.S. Treasury/IRS-related contract, management reported approximately $9 million of Q1 revenue and continued to expect:
IRM also highlighted strong government bookings and its FedRAMP High authorization, which broadens the workloads it can pursue with U.S. federal agencies.
Watch for:
Government wins could become an important source of upside, but bookings can take time to convert into reported revenue. Investors should distinguish contract announcements from actual implementation and recognized revenue.
IRM’s growth is increasingly capital-intensive. In Q1 the company invested:
Long-term debt plus its current portion stood at approximately $17.1 billion at March 31, up roughly $671 million from year-end. Net lease-adjusted leverage nevertheless improved to 4.8 times because EBITDA expanded.
Management expects full-year capital spending to be slightly below 2025 and said much of its data-center construction is supported by pre-leasing rather than speculative development. It also raised its expectation for year-over-year growth in retained cash flow.
Watch for:
Strong EBITDA growth can keep leverage under control, but a slowdown in leasing or a material increase in development spending would make the balance sheet a larger part of the debate.
Following Q1, management raised its 2026 outlook to:
| Metric | 2026 guidance | Midpoint growth |
|---|---|---|
| Revenue | $7.825B–$7.925B | ~14% |
| Adjusted EBITDA | $2.925B–$2.965B | ~14% |
| AFFO | $1.735B–$1.755B | ~13% |
| AFFO/share | $5.79–$5.86 | ~13% |
If Q2 lands exactly at company guidance, the second half would need to produce approximately:
That implies only modest second-half revenue acceleration, but stronger improvement in EBITDA and AFFO. Investors should therefore pay close attention to management’s quarterly cadence, lease-commencement schedule, margins and cash-flow assumptions.
Given the Q1 beat and comments about business momentum, a simple reaffirmation could be interpreted as conservative—or as a sign that some of the early upside is not recurring. A meaningful raise would be the cleanest positive catalyst.
The current quarterly dividend is $0.864 per share, or $3.456 annualized. Relative to the midpoint of 2026 AFFO-per-share guidance, the prospective payout ratio is approximately 59%, consistent with management’s low-60% target.
This leaves room for dividend growth, although data-center investment remains a major use of capital. Investors should watch for the balance management strikes between:
This would validate the premium valuation and reinforce IRM’s transformation from a records-storage REIT into a broader data-infrastructure and information-management growth platform.
Operationally this would be a sound quarter, but the share-price reaction could be muted given the stock’s strong year-to-date performance.
The greatest risk is not a collapse in the stable records business. It is that growth expectations for data centers and ALM prove too aggressive relative to the capital being committed.
IRM enters Q2 with excellent operating momentum but a much less forgiving valuation. The quarter should comfortably show double-digit year-over-year growth; that is already embedded in management’s guidance.
The more important questions are:
A straightforward “meet and maintain” quarter may be operationally satisfactory, but likely would not fully satisfy expectations after the stock’s roughly 51% year-to-date increase. The strongest outcome would combine an earnings beat, a materially higher leasing outlook, evidence of durable ALM volume growth, and another full-year guidance increase.
