Executive summary

Iron Mountain Q4 FY25 — Record Performance Driven by Data Center, ALM, and Digital Growth

Iron Mountain delivered a record fourth quarter and full year 2025, marking its fifth consecutive year of double-digit growth across key financial metrics. This strong performance was fueled by robust expansion in data center, Asset Lifecycle Management, and digital solutions, complemented by a resilient physical storage business. The company enters 2026 with significant momentum, projecting continued double-digit top and bottom-line growth, underpinned by a substantial data center pipeline and cross-selling opportunities.

Highlights

  • Record Q4 revenue of $1.84 billion, up 17% year-over-year.

  • Adjusted EBITDA grew 17% to $705 million, achieving a record 38.3% margin.

  • AFFO increased 17% to $430 million, with AFFO per share up 16% to $1.44.

  • Data center revenue surged 39% in Q4, with 43 megawatts leased and a strong backlog supporting over 25% revenue growth in 2026.

  • Asset Lifecycle Management (ALM) revenue grew 56% organically in Q4, driven by hyperscale and enterprise businesses.

Concerns

Detailed narrative

Data Center Momentum

Iron Mountain's data center business is experiencing robust demand, with 43 megawatts leased in Q4 2025 and an expectation to lease over 100 megawatts in 2026. The company's land bank includes 400 megawatts of available capacity, with half expected to energize within the next 18 months, primarily in key markets like Northern Virginia, Richmond, Madrid, London, and India.

This strong pipeline and current backlog are projected to drive over 25% revenue growth in 2026 and 20%+ growth in 2027.

Asset Lifecycle Management (ALM) Expansion

The ALM business saw significant organic growth of 56% in Q4 2025, contributing to a 63% total increase for the full year. This growth is driven by both hyperscale and enterprise segments, with the number of Fortune 1000 customers utilizing ALM services increasing to 360 from 270 in the prior year.

The company views ALM as a future multibillion-dollar business, with strong momentum from commercial wins and increased customer penetration.

Digital Solutions & DXP Growth

Digital solutions achieved an all-time high revenue of over $500 million in 2025, marked by double-digit growth. The AI-powered DXP platform secured a record number of deals in Q4, with average deal values more than double the prior year. New project wins and recurring business, now over 40% of digital revenue, are expected to sustain strong growth in 2026.

Resilient Physical Storage Business

The legacy physical storage business, a nearly $5 billion high-margin segment, achieved mid-single-digit revenue growth in 2025, marking its 37th consecutive year of organic storage rental revenue growth. This segment provides substantial cash flow, funding growth investments, and serves as a foundation for cross-selling to over 240,000 customers. The company remains committed to growing this business through innovation and revenue management strategies.

Operational Efficiency & Profitability

Iron Mountain demonstrated strong operational execution in 2025, expanding profitability with adjusted EBITDA increasing 15% and margin improving 90 basis points at the enterprise level. The adjusted EBITDA margin reached a record 38.3% in Q4. The company expects further EBITDA margin expansion in 2026, driven by SG&A leverage and the adoption of AI tools to improve efficiency.

Treasury Contract & Government Opportunities

The multiyear contract with the Department of Treasury recognized $6 million in Q4 2025 revenue, with a conservative outlook of $45 million for 2026 as the department ramps up outsourcing. The contract is expected to generate over $100 million annually from 2027 onwards. Iron Mountain's FedRAMP certification (moderate, with high pending) for its InSight SaaS platform positions it well for further federal government opportunities.
