Iron Mountain is turning its records-management base into a faster-growing information infrastructure platform, with data centers, digital solutions, and asset lifecycle management driving the next leg of growth. The business is improving, but the stock still screens expensive versus earnings and leverage remains elevated.
Investment thesis: Iron Mountain Incorporated (IRM) is converting a sticky records-management franchise into a faster-growing information infrastructure platform. In Q2 2026, revenue rose 19% to $2.03B, adjusted EBITDA increased 16% to $727M, and AFFO grew 17% to $433M. Data centers, digital solutions, and asset lifecycle management collectively grew more than 50% year over year and represented 35% of quarterly revenue.
The growth engine is credible. Management raised 2026 guidance to $7.94B-$8.01B of revenue, $2.95B-$2.98B of adjusted EBITDA, and $1.76B-$1.78B of AFFO. Data center leasing reached 110 megawatts year to date, while ALM revenue increased 88% in Q2. The core records business also delivered 5% organic storage growth and 9% organic service growth.
The counterweight is valuation and leverage. IRM trades at 84.8 times trailing earnings, 59.2 times forward earnings, and 2.7 times PEG, while 2025 year-end equity was negative $644.9M and debt was $16.75B. The result is a strong business with a demanding share price. For a moderate-risk investor with a medium-term horizon, the appropriate stance is Hold rather than chasing the growth narrative.
Iron Mountain was founded in 1951, converted to a REIT in 2014, and is based in Portsmouth, New Hampshire. The company employs approximately 29,400 people and serves more than 240,000 customers across 61 countries, including approximately 95% of the Fortune 1000.
IRM operates across physical records management, digital solutions, data centers, and asset lifecycle management. Its 2025 Form 10-K describes a business built around security, chain of custody, regulatory compliance, and long-standing customer relationships. No single customer accounted for more than approximately 3% of 2025 revenue, giving the company broad customer diversification.
Global Records and Information Management remains the foundation. The 2025 segment data lists $5.29B of revenue, or 86.8% of the reported segment total. In Q2 2026, Global RIM produced approximately $1.4B of revenue, up $110M year over year, and adjusted EBITDA of $621M at a 43.0% margin.
The records business is not standing still. Q2 storage revenue increased 7% on a reported basis and 5% organically. Service revenue increased 11% on a reported basis and 9% organically, led by digital revenue growth of more than 25%. This mix gives the legacy segment a useful combination of recurring storage revenue and higher-growth service activity.
Global Data Center revenue was $803M in 2025, or 13.2% of the reported segment total. Q2 2026 revenue reached $263M, up 39% year over year, with adjusted EBITDA of $137M and a 52.2% margin. ALM generated $288M in Q2, up 88% year over year. Management expects full-year ALM revenue to approach $1B, although the hyperscale channel includes timing effects from large projects.

Insight DXP is IRM's flagship digital platform. Version 2.0, launched in October 2025, added enhanced content management, smart document processing, workflow tools, and AI agents. The platform is designed to classify content, enrich metadata, apply governance rules, and help customers manage physical and digital information through a secure workflow.
The product has concrete customer activity behind it. A three-year managed services agreement with a fintech company covers 45 countries and is expected to process 500,000 inbound items annually. An Australian financial-services customer selected DXP to digitize 40 million images and automate records retention and destruction through Policy Center.
Management said the recurring portion of the digital business had risen above 45% of digital revenue. Forrester also recognized IRM as a top provider of document mining and analytics platforms, with Insight DXP scoring strongly in agentic AI functionality, data privacy, validation rules, globalization, and platform breadth.
IRM's strongest advantage is the combination of trust, scale, and chain-of-custody control. The 2025 Form 10-K identifies security, reliability, pricing, technology, and geographic scale as central competitive factors in records management. Customers in financial services, healthcare, government, legal services, and life sciences have a practical reason to avoid changing providers when sensitive information is involved.
The same advantage is extending into ALM. Management estimates the enterprise ALM market at $35B, with approximately 75% tied to the enterprise channel. IRM's global logistics network, data-erasure controls, refurbishment capabilities, and customer relationships allow it to sell ALM alongside records, digital, and data center services.
Compliance credentials reinforce the sales proposition. IRM achieved portfolio-wide HITRUST r2 accreditation in June 2026, while its data centers also carry certifications including ISO 27001, SOC 2, PCI-DSS, HIPAA, NIST 800-53, and FISMA High. The company also cites FedRAMP High authorization and Google Partner of the Year recognition.
The operating network is unusually broad. At December 31, 2025, IRM stored more than 740 million cubic feet of physical records, operated 31 data centers across 21 global markets, and ran 34 ALM facilities across eight global markets. Its data center platform included 488 megawatts of leasable capacity, with another 852 megawatts under construction or held for development.
Q2 execution supports the expansion plan. IRM invested $553M of growth capital expenditure and $38M of recurring capital expenditure during the quarter. Year-to-date operating cash flow reached $888M, up $315M year over year, while management attributed the improvement in first-half free cash flow to business growth, a better cash cycle, and the completion of Project Matterhorn restructuring costs.
The data center supply chain remains tied to power and construction timing. IRM had approximately 325 megawatts expected to energize over the following 24 months after Q2 and July leasing activity. London, Amsterdam, Mumbai, Richmond, Europe, India, and Northern Virginia were named as important locations in the leasing pipeline.
IRM operates in several markets with different growth profiles. Physical records management provides recurring revenue and mid-single-digit organic storage growth. Digital solutions benefit from enterprise digitization and information-governance demand. Data centers address cloud and AI infrastructure requirements, while ALM addresses secure IT decommissioning, refurbishment, recycling, and resale.
The data center market is the most visible growth driver. IRM leased 13 megawatts in Q2 and another 75 megawatts in July, taking year-to-date leasing to 110 megawatts. A 51-megawatt Mumbai lease with a major global hyperscaler carries a 10-year term, while London and Amsterdam leases were linked to demand for AI inference capacity.
ALM also has substantial runway. Management said the hyperscale data center decommissioning market could expand from $3B to approximately $6B over four to five years. Enterprise ALM revenue is expected to exceed $600M for the full year and has grown roughly 15 to 20 times over the prior five to six years, according to the Q2 call.

IRM's customer base is large, diversified, and concentrated in industries where security and compliance have economic value. The 2025 filing names commercial, legal, financial, healthcare, technology, insurance, life sciences, energy, entertainment, business services, and government organizations as customer verticals.
The cross-selling opportunity remains significant because approximately 5% of customers bought services from more than one IRM business unit at the end of 2025. Recent wins show the model in practice: a global financial institution selected Smart Sort to process 10 million files, a Canadian financial institution selected IRM for national IT decommissioning, and an Australian government department awarded a contract covering 100,000 IT assets annually.
Customer concentration is manageable at the company level, with no single customer contributing more than approximately 3% of 2025 revenue. The main customer risk is operational rather than concentration-based: a security failure, service interruption, or chain-of-custody breach could affect reputation and create regulatory costs.
Records management remains fragmented, with regional storage operators and internal corporate systems competing against IRM. Digital content and workflow competitors include OpenText (OTEX), Oracle (ORCL), IBM (IBM), and Hyland. The competition is based on price, reliability, security, technology, and the ability to manage information across jurisdictions.
Equinix (EQIX) and Digital Realty (DLR) are the clearest public data center comparisons, although IRM's business also includes records, digital, and ALM services. Data center competition centers on power availability, location, connectivity, security, and rental rates. IRM's 10-K states that five of the largest global hyperscalers are among its data center customers.
IRM's differentiation is breadth rather than a single product. Its 240,000-customer base, 61-country footprint, physical storage network, data center capacity, and secure asset-processing capabilities allow it to pursue global contracts that smaller specialists cannot easily replicate. That advantage is strongest where customers want one provider for security-sensitive work across multiple regions.
Foreign exchange affected the 2026 outlook. On the Q2 call, management said currency contributed approximately $14M of year-over-year revenue, below the prior assumption because the U.S. dollar strengthened after the previous call. IRM operates in 61 countries, so currency movement remains a direct factor in reported results.
Regulation is both a market opportunity and a risk. The 2025 Form 10-K describes increasingly complex data privacy and cybersecurity rules and cites potential fines, litigation, remediation costs, and reputational damage from violations or breaches. The filing also identifies environmental compliance and remediation obligations tied to certain current and former properties.
IRM's clean-energy positioning supports its data center sales effort. The company has matched 100% of data center energy consumption with clean energy annually since 2017 and offers Green Power Pass, allowing customers to report power consumed at IRM facilities as clean power in public reporting.
Debt stood at $16.75B against negative 2025 year-end equity of $644.9M, leaving Iron Mountain with a balance sheet that supports growth but limits flexibility.

Get Full Access →Iron Mountain has built a stronger growth story than its legacy records label implies. Q2 2026 established operating momentum across all major growth engines: data center revenue rose 39%, ALM revenue rose 88%, digital revenue grew more than 25%, and Global RIM storage revenue grew 5% organically.
The investment case remains balanced. A 240,000-customer base, global compliance capabilities, recurring storage revenue, and a large data center pipeline support durable growth. Debt, negative equity, capital intensity, margin mix pressure, and an 84.8 times trailing P/E restrain the upside at the current price. With the report's $125.00 fair-value estimate above the $117.57 reference price but below the $144.00 consensus target, Hold is the disciplined medium-term conclusion.
