GoodMoat Analysis

Based on data as of March 26, 2026

Iron Mountain appears unfavourable from a value investing perspective. The current price of $100.53 is significantly above the GoodMoat Target of $69.80, indicating a negative margin of safety. The stock's extreme P/E ratio of 205.5 and negative free cash flow yield are major concerns.

Read full analysis
Based on the GoodMoat Investment Framework, Iron Mountain's valuation metrics present significant challenges. The primary valuation tool is the Discounted Cash Flow (DCF) model, which yields a GoodMoat Target of $69.80. At a current price of $100.53, this indicates a negative margin of safety of approximately -44%, placing it firmly in the 'Unfavourable' band (less than 10% MoS). This suggests the stock is trading well above its estimated intrinsic value. The P/E ratio of 205.5 is exceptionally high, far exceeding typical value thresholds. While a high P/E can sometimes be justified for a high-growth company, a 16.6% revenue growth rate does not support such an extreme multiple. The negative Free Cash Flow (FCF) Yield of -3.1% is a critical red flag, as it fails the framework's check for a positive and growing FCF conversion. This combination of negative cash flow and extreme valuation multiples, when compared against the framework's benchmarks, suggests the stock is expensive relative to its current financial quality and offers no margin of safety for a value-oriented investor. Analysis based on data as of 2024-05-15.
