Pam Nicholson

Enterprise’s revenue in fiscal 2016 topped $20 billion, cementing its status as the world’s largest rental-car company. Helping drive that growth is Nicholson’s push into markets like New Zealand, ­Ecuador, and the Gulf region, where it launched new franchises over the past year. The owner of National Car Rental and Alamo Rent A Car brands expanded its airport rental business. It has continued building out its car sales division (with double-digit growth last year), as well as its fast-growing car-­sharing businesses. Uber, watch out.
