Iron Mountain stock falls 2.57 percent as Q2 growth holds

Iron Mountain stock fell 2.57 percent to USD 115.09 on the NYSE on September 23, 2026, giving back part of its recent advance even as second-quarter revenue reached USD 2.03 billion. The earnings profile shows a company growing faster in data centers and digital services than in its traditional storage operations.

Revenue growth clears expectations

Iron Mountain reported second-quarter revenue of USD 2.03 billion, an 18.5 percent increase from the same period a year earlier, according to MarketBeat. Adjusted earnings per share reached USD 0.60 in the quarter, exceeding the USD 0.54 consensus estimate by USD 0.06.

The comparison matters because the revenue increase was accompanied by a return to profitability and operating income of USD 373.5 million in the second quarter. That combination gives the current valuation a clearer operating foundation than a price move alone.

Data centers widen the growth mix

Data center revenue climbed to USD 262.9 million from USD 189.4 million a year earlier, while storage rental revenue increased 37.5 percent, according to Zacks. Segment adjusted EBITDA rose to USD 137.3 million, and its margin expanded to 52.2 percent from 50.8 percent.

Iron Mountain says its platform spans more than 30 data centers across three continents and serves 1,300 data center customers. The company also lists digital platforms, information governance and IT asset lifecycle management among its operating areas, giving investors several growth channels beyond physical records storage.

Stock retreats from yearly high

Iron Mountain was quoted at USD 115.09 on September 23, 2026 at 4:00 p.m. ET, down USD 3.04 from the previous close of USD 118.13. Its market capitalization stood at USD 34,242,115,536, while the 52-week range ran from USD 77.77 to USD 134.68.

The price was 14.55 percent below the 52-week high, while the stock remained 47.98 percent above its 52-week low. The figures put the daily decline into perspective: the shares weakened in the session, but the broader one-year trading band still reflects a materially higher valuation than the yearly floor.
