United Rentals, Inc.

United Rentals, Inc. is the largest equipment rental company in the world, operating a fleet of approximately 1.1 million units worth $22.5 billion at original equipment cost across 1,768 locations in the United States and Canada, with smaller operations in Europe, Australia, and New Zealand. The company generated $16.1 billion in total revenue in fiscal 2025, of which 86% came from equipment rentals — renting everything from aerial work platforms and earthmoving machinery to trench safety systems and portable power solutions to construction and industrial customers.

This is a story about density and debt. United Rentals has built the only genuine nationwide platform in an industry still populated by thousands of independent operators, and the economics of that network — procurement power, fleet sharing across branches, the ability to serve national accounts — are real and durable. But the platform was built with borrowed money, and it still consumes capital at a rate that makes the distinction between growth investment and maintenance spending blurry. The file turns on whether URI's scale advantages compound into widening returns on capital, or whether the leverage inherent in both the balance sheet and the operating model makes the business more cyclical than its defensive diversification suggests.
