IRON MOUNTAIN INC (IRM)

Iron Mountain demonstrates strong cash flow growth with AFFO per share increasing 16% year-over-year to $1.44 in Q2 2026 and 19% year-to-date to $2.87, well above flat performance. The quarterly dividend of $0.864 per share annualizes to approximately $3.46, yielding a payout ratio of roughly 60% of trailing AFFO per share ($2.87 annualized), comfortably below the 75% threshold. The company has raised guidance for full-year 2026 AFFO per share to $5.87–$5.93 (14% growth), indicating sustained momentum and confidence in continued dividend growth, consistent with a multi-year track record of increases.

Iron Mountain's balance sheet strength cannot be fully assessed from the provided data, as net debt/EBITDA and debt maturity ladder information are missing. However, the company demonstrates strong operational momentum with Q2 2026 Adjusted EBITDA of $727 million (up 15.7% YoY) and AFFO per share of $1.44 (up 16.1% YoY), supporting debt service capacity. The payout coverage ratio of 1.2x indicates modest cushion above the dividend, and the price-to-FFO multiple of 30.2x suggests market confidence in earnings quality. Without explicit leverage metrics or debt structure details, the score reflects operational strength offsetting the inability to confirm debt ratios fall within investment-grade parameters.

Iron Mountain demonstrates strong operating performance with organic revenue growth of 16.8% year-over-year in Q2 2026, Adjusted EBITDA growth of 15.7% (14.9% constant currency), and AFFO per share growth of 16.1%. Storage rental revenue increased 12% and service revenue grew 26.3%, with growth businesses (data center, digital, ALM) collectively growing over 50% year-over-year. However, the rubric's anchor for a score of 5 requires SSNOI growth of 3%+ consistently with occupancy data at 95%+ stable and positive spreads—metrics not disclosed in this filing. The company shows strong momentum and exceeds the 2%+ SSNOI growth implied by the score-3 anchor, but without explicit occupancy rates and spreading data, the assessment cannot reach the highest tier.

Iron Mountain operates in information management and data centers, sectors with secular tailwinds driven by digital transformation, data proliferation, and cloud infrastructure demand. The company serves over 240,000 customers including 95% of the Fortune 1000, demonstrating significant tenant diversification and creditworthiness. Growth businesses (data center, digital, ALM) grew over 50% year-over-year with 110 megawatts of data center leasing year-to-date, indicating exposure to supply-constrained, high-demand markets. However, the core physical records storage business, while stable, faces structural headwinds from digitalization trends, preventing a perfect 5 score despite strong execution and modern asset expansion.

Iron Mountain demonstrates mixed capital allocation characteristics. Management shows strong operational execution with 16-21% per-share growth (FFO up 16.1% and AFFO per share up 16.1% in Q2), and the company increased full-year guidance, indicating disciplined capital deployment. However, the price-to-FFO multiple of 30.2x is elevated relative to historical norms, and the dividend yield of 2.77% with 1.2x payout coverage suggests reliance on external capital raises to fund growth rather than purely accretive issuance. The earnings release emphasizes organic growth and operational improvements but lacks disclosure of insider ownership levels or explicit commentary on share issuance discipline, placing the company in the middle range of the rubric.
