Shares of Iron Mountain (NYSE:IRM) tumbled 5.02% in Wednesday's intraday trading session following the release of its second-quarter 2025 financial results. The data storage and information management company reported mixed results, with earnings falling short of analyst expectations despite beating revenue estimates.

Iron Mountain reported adjusted earnings per share (EPS) of $0.48, missing the analyst consensus estimate of $0.50 by 4%. However, this represents a 14.29% increase from $0.42 per share in the same quarter last year. The company's quarterly revenue came in at $1.712 billion, surpassing the analyst estimate of $1.683 billion by 1.73% and marking an 11.60% year-over-year increase.

Despite the revenue beat and raised full-year outlook, investors seemed to focus on the earnings miss and the reported net loss of $43 million for the quarter. The company's GAAP EPS showed a loss of $0.15, which likely contributed to the negative market reaction. Iron Mountain's adjusted EBITDA margin of 36.7% and adjusted EBITDA of $628 million, which beat estimates, were not enough to offset concerns about profitability. The stock's decline suggests that market participants may be worried about the company's ability to convert revenue growth into bottom-line profits in the current economic environment.
