The quarter reflected broad-based momentum, led by strong expansion in growth businesses and solid pricing in the core storage franchise. Organic revenue growth was 17.2% year over year, underscoring continued demand and effective revenue management. The company raised its 2026 FFO per share outlook.
Total revenues of $1.94 billion beat the consensus mark by 4.31% and rose 21.6% year over year.
IRM's Revenue Mix Skews to Service Upside
Storage rental revenues increased 15.4% year over year to $1.095 billion. On a constant-currency basis, storage rental revenues rose 12.6%, supported by sustained pricing actions and resilient underlying demand.
Service revenues climbed 30.6% year over year to $841.4 million, with constant-currency growth of 27.6%. The faster service line growth continued to lift total revenue growth, aided by higher activity levels across servicing and solutions-oriented offerings.
Iron Mountain's Segment Results Show Broad Strength
Global RIM revenues rose 11.8% year over year to $1.404 billion, driven by higher storage rental and service revenues. Organic growth for the segment was 8.3% on a constant-currency basis, showing that the core records management engine is still expanding, even as the company scales newer offerings.
The Global Data Center segment delivered a 47.1% revenue increase to $254.7 million, reflecting continued portfolio expansion and favorable leasing dynamics. Corporate and Other revenues increased 69.7% to $277.3 million, with management attributing growth in part to Asset Lifecycle Management strength, which is reported within this segment.

Operationally, Iron Mountain ended the quarter with 507.2 leasable megawatts in its operating portfolio and a 97.2% leased rate by megawatts on a total portfolio basis. Stabilized assets were 98.3% leased, highlighting tight utilization as the company brings additional capacity online.
Leasing activity remained healthy. The company signed 21,849 kilowatts of new and expansion leases in the quarter, while churn was just 0.4%. Renewal pricing was favorable, with cash mark-to-market at 12% and GAAP mark-to-market at 14%, indicating continued pricing power at lease rollover.

In the storage franchise, total global storage volume reached 745,276 thousand cubic feet at quarter-end. Storage facility capacity utilization improved to 81.4%, and the records management retention rate was 93.3%, reinforcing the stickiness of the long-duration storage base that supports recurring cash flows.
Pricing and productivity measures also showed up in unit economics. Storage revenue per square foot increased to $11.74, while storage NOI per square foot was $9.10. These metrics suggest ongoing benefit from revenue management initiatives, even as the company continues to invest in growth categories.
