    Executive summary

    Iron Mountain Q3 FY25 — Record Performance Driven by Data Center, Digital, and ALM Growth

    Iron Mountain delivered record Q3 FY25 financial results, driven by robust performance across its data center, digital solutions, and asset life cycle management segments, which collectively accounted for two-thirds of total revenue growth. The company also announced a 10% dividend increase, reflecting strong execution and a positive outlook, despite some sequential gross margin shifts due to business mix and power pass-throughs.

    Highlights

    5

    • Record quarterly revenue of $1.75 billion, up 13% on a reported basis.

    • Record adjusted EBITDA of $660 million, up 16%, with margin improving 110 basis points.

    • Record AFFO of $393 million, up 18%, and AFFO per share of $1.32, up 17%.

    • Data Center revenue grew 33% year-on-year, with a strong outlook for over 25% growth in 2026 based on signed leases.

    • Asset Life Cycle Management (ALM) revenue grew 65% reported and 36% organically.

    Concerns

    3

    • Sequential gross margin for storage was down due to data center power pass-throughs and lower data center gross margin.

    • Sequential gross margin for services was down due to business mix shift towards lower-margin ALM and Digital businesses.

    • FX strengthening is expected to be more challenging on a sequential basis in Q4 FY25.

    TargetSignificant ramp in H1 FY26

    Why it matters

    The successful ramp-up of this major new contract will significantly impact Digital Solutions revenue and overall growth.

    we recognized revenue of approximately $2 million in the third quarter and expect $4 million in the fourth quarter prior to building into tax season in the first half of next year.

    Q&A highlights

    8

    Will the $714 million 5-year contract with the U.S. Treasury ramp linearly or be front-end loaded, especially with seasonal volumes in spring 2026?

    The contract is expected to ramp linearly with slight growth over 5 years, not front-end loaded, but will have seasonality around tax season. The company is preparing for high seasonal volume in spring 2026 by staffing up.

    “it will be linear with slight growth as you go forward as people get added to the taxpayer role over that 5-year contract. So it isn't front-loaded per se. But there is a seasonality aspect to do with tax season, right, so which is generally in the spring for most people.”

    Detailed Narrative

    01

    Strategic Growth Drivers and Portfolio Mix

    Iron Mountain's growth portfolio, comprising data center, digital solutions, and asset life cycle management (ALM), was a significant contributor, driving two-thirds of the company's Q3 FY25 revenue growth. This portfolio is projected to represent nearly 30% of total revenue by the end of 2025. The physical storage business continues to demonstrate strength, growing at a mid-single-digit rate and contributing approximately 5 points to consolidated growth in 2025, underscoring a balanced and diversified growth strategy.

    02

    Digital Solutions Momentum and Treasury Contract Win

    The company is building momentum in its Digital Solutions business, marked by the successful launch of its Insight DXP 2.0 platform in late October, offering enhanced content management and AI-powered smart document processing. A significant win includes a new 5-year contract with the U.S. Department of Treasury, valued at up to $714 million, for digitization services. This expands Iron Mountain's existing scope and is expected to see high seasonal volume in spring 2026, leveraging the DXP platform's capabilities.

    03

    Robust Data Center Market and Leasing Activity

    The data center market remains very strong, with a noticeable pick-up in leasing activity and pipeline as hyperscalers renew their focus on inference and cloud capacity build-out. Iron Mountain leased 13 megawatts (MW) in Q3, including larger enterprise deals. Early in Q4, a key hyperscaler leased an entire 36 MW Chicago site, transferring and expanding a previous 25 MW London lease for a net incremental 11 MW, demonstrating strong demand and strategic customer flexibility.

    04

    Asset Life Cycle Management (ALM) Expansion

    ALM represents a major growth opportunity for Iron Mountain, operating in a large and highly fragmented market. The company is capitalizing on this through expanding business with existing customers, acquiring new clients via cross-selling, and strategic acquisitions like ACT Logistics in Australia, which strengthens its market leadership. Q3 results reflect successful execution, driven by strong enterprise volume and favorable component pricing trends.

    05

    Synergistic Business Model in Action

    Iron Mountain's synergistic business model is evident in recent commercial wins. A leading financial services company, a long-term records management and digital solutions partner, selected Iron Mountain for ALM services. Similarly, a global German company engaged Iron Mountain for ALM support across six data centers, building on existing records management, digital, and data center co-location services. These examples highlight the power of cross-selling and integrated solutions.

    06

    Capital Investment Strategy for Data Centers

    The company's approach to data center capital expenditure focuses on building to pre-leased assets rather than speculative development. Investments are directed towards high-return contracts already signed with high-credit-quality hyperscale customers. While not chasing 1-gigawatt large language model campus build-outs, Iron Mountain targets inference and cloud build-out, with data center CapEx expected to gradually rise in line with additional leasing expectations.
