URI vs APO Comparison

United Rentals is the world's largest equipment rental company, principally operating in the US and Canada. It has 16% share in a highly fragmented market serving general industrial (49%), commercial construction (46%), and residential construction (5%). The company operates a $21 billion fleet of equipment, including aerial platforms, forklifts, excavators, trucks, power generators, and various other materials serving local and national accounts from nearly 1,600 locations in North America and 100 abroad. It has pursued a strategy of bundling specialty rental capabilities to offer its customers more advanced solutions in addition to its core equipment rental business, supporting its ambitions to become a one-stop shop for customers and enhance and maintain its margin profile.
