Another View: Iron Mountain Through Earnings Multiples

Iron Mountain might look cheap on intrinsic value models, with the SWS view pointing to a future cash flow value of $175.63 against a $118.13 price. The P/E picture tells a very different story. The stock trades on 84x earnings versus a peer average of 17.2x and a fair ratio of 42.3x, which suggests a rich valuation if profitability or growth expectations slip.

This kind of gap can work either way for investors. If earnings progress stalls or sentiment cools, a move toward that 42.3x fair ratio could mean a lot of downside without any change in profits.
