Iron Mountain (IRM) Q3 revenue $2.0 billion vs $2.01 billion est.; raises full-year guidance

Iron Mountain reported third-quarter 2026 revenue of $1.99 billion, up 13.5% year over year but just below the $2.01 billion analyst estimate, with net income of $129 million and record adjusted EBITDA of $748 million at a 37.6% margin. The company signed 102 megawatts of data center leases in the quarter, bringing year-to-date leasing to 137 megawatts, and raised its full-year 2026 guidance while lifting its quarterly dividend 15%. CEO William L. Meaney attributed the results to cross-selling across ALM and digital and said the leasing pipeline supports future growth. Investors will watch whether the revenue miss against consensus is offset by the guidance raise and dividend increase, and how quickly the leased data center capacity converts into revenue.
