Most Popular Narrative: 22% Undervalued

On the most followed view, Iron Mountain’s fair value sits at $144.91, comfortably above the recent $112.51 close. This view places more weight on long-term cash generation than on the latest share price move.

Use of cash flow from the physical records management business, which management describes as highly cash generative with stable to slightly rising volumes and consistent pricing, together with net lease adjusted leverage of about 4.8x and a US$1.5b senior notes issue maturing in 2035, underpins continued funding of growth projects in data centers, ALM and digital without relying on equity issuance, which can support future AFFO per share and dividend capacity.

See why 48 investors see Iron Mountain as 22% undervalued.

Result: Fair Value of $144.91 (UNDERVALUED)
