BROOKFIELD CORPORATION vs IRON MOUNTAIN INC, two REIT stocks. A side-by-side on valuation, growth, margins, returns, and what each price is betting.
The single figure worth noting is what neither P/E tells you: Iron Mountain at 144 times GAAP earnings and Brookfield at 84, both multiples distorted, IRM's by records-storage-and-data-center depreciation, Brookfield's by asset-mark timing. Iron Mountain is transforming from physical records storage into data centers, its funds-from-operations growing as the mix shifts; Brookfield is a diversified owner-manager of infrastructure and real estate. IRM pays a 2.43% dividend on its storage-and-data cash flows; Brookfield none listed. IRM's leverage is high (shown as blank, but real); Brookfield shows none on this page. The pair prices a storage-to-data-center REIT against a diversified compounder; IRM offers a transforming cash stream with a real dividend, Brookfield capital appreciation, and both are misread through their reported earnings.
