Iron Mountain (IRM)
75-year-old records-management giant pivoting to AI-era data centers — from paper boxes to gigawatt buildouts.
1. Core Product / Service
Iron Mountain's heritage business is physical records storage and information management (paper, tapes, secure shredding, art storage) — the largest in the world, serving 95% of the Fortune 1000. Since the mid-2010s, IRM has aggressively reinvested into a second growth engine: data centers (Iron Mountain Data Centers, IMDC).
Today's IMDC business:
- ~507 MW of operational capacity, scaling toward 1.4 GW total developable capacity [1][2]
- Mix of retail and hyperscale colocation across 20+ markets globally
- Specialty: secure / sovereign / underground sites (e.g. former limestone mine in Pennsylvania) for regulated workloads
- Increasing focus on hyperscale build-to-suit for AI inference and cloud capacity [3]
The 2025-2026 narrative: records management is the cash cow, data centers are the growth engine — and AI inference demand is the demand pull justifying a triple-up of capacity.
2. Target Users & Pain Points
- Hyperscalers wanting incremental capacity in non-Tier-1 markets where IRM has land + power
- Regulated industries (financial, healthcare, government) leveraging IRM's compliance heritage and secure facility designs
- Enterprises consolidating from on-prem to colo
Pain solved: secure colocation with deep compliance experience, plus increasingly hyperscale-class power densities. In 2026, IRM's main constraint isn't demand — it's how fast they can energize MW.
3. Competitive Landscape
| Company | Data Center Scale | Positioning vs IRM |
|---|---|---|
| equinix | 260+ IBX, far larger | Bigger, more interconnection-dense |
| digital-realty | ~300 facilities | More wholesale tenant base |
| qts | ~3 GW (Blackstone) | Pure hyperscale; private |
| Aligned Data Centers | ~1 GW+ | Private hyperscale rival |
| Stack Infrastructure | Smaller | IPI partners, hyperscale focus |
IRM's differentiator: records-management cash flow funds the data-center buildout, plus a unique installed base of underground/secure sites. The "boring legacy core funds the growth pivot" model is closer to Microsoft's path with Azure than to a pure-play data-center REIT.
4. Unique Observations
- Q1 2026 records: organic growth hit a 25-year high; data center revenue on track to exceed $1B in 2026 (+25% growth) [3]. Total company guidance raised on data center momentum.
- Capacity ramp: 507 MW operational →
400 MW available-to-lease energizing over the next 24 months (175 MW within 18 months) → eventual 1.4 GW total developable [1][2]. Roughly tripling MW over a multi-year horizon. - 2026 leasing pace: 22 MW leased in Q1, 10 MW in April → 32 MW year-to-date by Q1 call. Management expects to "finish meaningfully above" the 100 MW full-year target [1]. AI inference demand is the catalyst.
- AI-driven hyperscaler pull-through: IRM specifically calls out hyperscalers building inference capacity (not just training) as the demand source [1]. This is the same theme as digital-realty's 200 MW Charlotte deal — inference is decentralizing into more markets, and tier-2-market colos like IRM benefit.
- Customer concentration risk: while not as concentrated as coreweave, IRM's data center backlog is dominated by a small number of hyperscaler tenants. Records management diversification mitigates company-level risk.
- $/MW economics — implied: 1.4 GW total developable, IRM has discussed multi-billion dollar expansion. Backing into ~$10-12M/MW build cost is consistent with industry baseline. Records-management free cash flow finances ~$300-500M/year of data-center capex without straining the balance sheet.
- The "pivot" thesis is real but slow: data centers are still the minority of total revenue, but they're 100% of the growth narrative — the equity story is increasingly "records cash cow + hyperscale growth optionality."
5. Financials / Funding
- Listed: NYSE: IRM, REIT structure
- Data center revenue: on track for >$1B in 2026, +25% YoY [3]
- Operational MW: ~507 MW
- Total developable: 1.4 GW [1][2]
- 2026 leasing target: 100 MW (expected to finish meaningfully above) [1]
- 2026 organic growth: 25-year high — multi-segment momentum [2]
- Note: total company revenue is multi-billion ($6B+ TTM range), driven primarily by records management; IRM does not separately disclose all DC line items.
6. People & Relationships
- CEO: Bill Meaney (long-tenured CEO since 2013)
- President, IMDC: Mark Kidd (heads data center segment)
- Founded: 1951 (records management); IMDC entity established mid-2010s through acquisitions of Mag Mile Capital, IO Data Centers (2017), and others
- Top customers: 95% of Fortune 1000 use records-management; data-center customer list more concentrated (hyperscalers + regulated enterprises, not publicly enumerated)
- Strategic context: in many ways, the most "Wall Street-friendly" pivot story in colo because the records cash flow buffers data-center execution risk
