Iron Mountain brought in $4.76B from its two product and service lines in fiscal 2017, the year ended December 31, 2017.

Iron Mountain brought in $6.93B from its three segments in fiscal 2017, the year ended December 31, 2017. Iron Mountain regrouped these segments after fiscal 2016, so the total does not compare directly with that year's $908.42M. Operating Segments was the largest at $4.10B (59.2%), ahead of Reportable Legal Entities at $2.89B (41.7%).
The total is net of Eliminations, which took $58.38M off revenue in fiscal 2017.
