Frequently Asked Questions
What is the PE ratio of IRM?
The trailing twelve-month PE ratio of IRM reflects how much investors pay per dollar of Iron Mountain Incorporated's earnings. This metric is most useful when compared to REIT - Specialty peers and the company's own historical range.
Is IRM overvalued based on PE ratio?
IRM's PE of 138.7x combined with a PEG ratio of 1.14 provides a growth-adjusted perspective. A PEG near 1.0 suggests the PE ratio is reasonably justified by the earnings growth rate. Keep in mind that PE-based valuation works best for profitable, mature companies — for high-growth or cyclical REIT - Specialty, a DCF analysis may be more appropriate.
How do I value IRM stock using PE ratio?
To value Iron Mountain Incorporated using PE: (1) Compare the current PE (138.7x) against the REIT - Specialty median to assess relative pricing, (2) check the PEG ratio (1.14) to adjust for growth expectations, (3) review the 5-year PE range to identify where the stock sits historically, and (4) estimate fair value by multiplying a target PE by forward EPS estimates. This relative approach complements DCF's absolute valuation.
What is the PEG ratio of IRM?
IRM's PEG ratio is 1.14, calculated by dividing the PE ratio (138.7x) by the expected earnings growth rate. A PEG near 1.0 suggests the stock is fairly priced relative to growth. Note that PEG accuracy depends on the reliability of growth estimates.
Should I use PE ratio or DCF for IRM stock valuation?
PE ratio gives a quick relative read — how IRM is priced versus REIT - Specialty peers. DCF provides an absolute value based on projected free cash flows. For the most reliable valuation, use PE as a quick comparability screen and DCF for a deeper fundamental analysis. Each method has blind spots: PE ignores capital structure and cash flow quality, while DCF is sensitive to growth and discount rate assumptions.
