Iron Mountain beats revenue expectations, raises full-year guidance

Iron Mountain (IRM) reported record Q2 2025 revenue of $1.71 billion, exceeding analyst estimates, which contributed to a 1.51% pre-market stock increase. Despite a slight miss on adjusted EPS and a net loss primarily due to foreign exchange effects, the company achieved record adjusted EBITDA of $628.4 million and record AFFO, driven by strong operational performance across its data center and digital segments. Consequently, IRM raised its full-year 2025 revenue and AFFO per share guidance, signaling a robust outlook for investors.

Analysis

Iron Mountain (IRM) reported a mixed but operationally strong second quarter for 2025, with record revenue of $1.71 billion surpassing analyst expectations and growing 11.6% year-over-year. While adjusted EPS of $0.48 slightly missed the $0.50 consensus, the market appears to be looking through this and the reported net loss of $43.3 million. This loss was attributed almost entirely to a non-operational $43 million currency exchange loss, which contrasts with a net income of $34.6 million in the prior-year quarter. The core operational health of the company is demonstrated by record quarterly adjusted EBITDA of $628.4 million, up 15.4% YoY, and record AFFO of $369.7 million. Growth was notably strong in the data center, digital, and asset lifecycle management segments, which collectively expanded by over 30%, validating the company's strategic focus. This high-growth performance was complemented by a solid 9.8% increase in traditional storage rental revenue. Reflecting this underlying strength, management raised its full-year 2025 guidance for both revenue and, more significantly, AFFO per share to a range of $5.04-$5.13, signaling confidence in sustained momentum.

Key Decisions for Investors

• Investors should focus on the strong operational metrics, such as the 15.4% growth in adjusted EBITDA and record AFFO, rather than the headline EPS miss or the non-operational FX-driven net loss.
• The raised full-year AFFO per share guidance is a key positive signal, providing a stronger basis for valuation and suggesting management's confidence in future cash flow generation.
• The outsized growth of over 30% in the data center and digital segments confirms the success of the company's strategic pivot, and these segments should be monitored as the primary drivers of long-term value.
• Given the stock's modest 1.51% pre-market rise, the positive revisions to guidance may not be fully priced in, presenting a potential opportunity for investors confident in the operational outlook.
