Why a DCF Doesn't Fit Iron Mountain Incorporated (IRM)
REIT - Specialty · NYSE
A cash-flow DCF is not the right model for IRM
Iron Mountain Incorporated is a bank, insurer, or real estate company. A standard discounted cash flow model values a business on its free cash flow, but for these companies free cash flow is not a clean measure of value. Banks and insurers are valued on book value, return on equity, and a price-to-earnings multiple; REITs are valued on funds from operations (FFO) and dividends, not free cash flow. Running a free cash flow DCF here would produce a misleading number, so none is shown.

Frequently Asked Questions
Why isn't a discounted cash flow model right for valuing Iron Mountain Incorporated?
As a REIT, Iron Mountain Incorporated must pay out most of its income as dividends and carries heavy non-cash depreciation on its buildings, so reported net income and free cash flow understate how much the properties actually earn. A DCF built on those figures misses the real cash the portfolio produces. A REIT is read on funds from operations and dividends instead.
How is Iron Mountain Incorporated (IRM) valued instead?
Iron Mountain Incorporated is better read through price-to-FFO, which uses funds from operations, and the dividend yield rather than price-to-earnings, together with occupancy and the quality of its properties. The IRM PE view is a starting point, but multiples based on funds from operations fit a REIT better.
