Munger Mode rating: 3 out of 5 — Hold. Our own rating from the research report below, on business quality first: moat durability and management, with price separating the top three.
We like simple businesses, and they don't come much simpler than renting a metal box with a lock on it. Extra Space Storage is the best operator in American self-storage — a genuinely well-run company with capable, honest management, sector-leading operating results, and two lovely capital-light side businesses bolted onto the real estate. If you handed us the whole company at a sensible price, we'd take it and sleep well. But we are not being handed the whole company at a sensible price. We are being offered shares at roughly 18 times this year's Core FFO, with $13.6 billion of debt sitting on top, in an industry that has proven — twice in the last decade — that it cannot restrain itself from building too many storage sheds when times are good.
