Iron Mountain Investment Narrative Recap

To own Iron Mountain, you generally need to believe that its shift from legacy physical storage toward higher value data centers and digital solutions can offset pressure on older, paper-based workflows. The recent drop in short interest points to easing bearish pressure, but it does not materially change the near term picture, where the key catalyst is execution on growth projects and the biggest risk remains heavy leverage and capital needs for data center expansion.

One recent development that stands out in this context is the February 2026 earnings and guidance update, where Iron Mountain reported full year 2025 revenue of US$6,901.74 million and provided 2026 guidance of up to US$7,775 million. This anchors the conversation around whether rising confidence in the stock, reflected in lower short interest, lines up with its ability to fund ongoing expansion while managing interest costs and the strain on free cash flow.

Yet beneath improving sentiment, investors should be aware of how Iron Mountain's elevated leverage could affect...
