The nation’s biggest companies that didn’t exist in 2010

The Fortune 500 list of the largest U.S. public companies by revenue is dominated by decades-old and even century-old companies.

Still, there are a handful of exceptions. Every year, new startups are formed and conglomerates are restructured—and in some cases, these companies soon report revenues high enough to rank among the largest U.S. companies. USA Today reviewed a range of sources, including the Fortune 500, to identify America’s biggest companies that did not exist a decade ago. 

While there have been dozens of notable startups in the last decade, many that could one day break onto the Fortune 500, every company large enough to rank on this list was formed after a larger company divested some of its business. In these cases, the billions of dollars in annual revenue are largely attributable to the customer base and infrastructure established when the company was part of a larger conglomerate. 

• Biopharmaceuticals company AbbVie was founded Jan. 1, 2013, as a spinoff from Abbott Laboratories. While the new Abbott Laboratories would focus on diagnostic and medical devices, AbbVie was founded to focus on research-based pharmaceuticals. Latest annual revenue: $33.3 billion

Hewlett Packard Enterprises, or HPE, was formed Nov. 1, 2015, when it separated from Hewlett Packard. The split was executed so HPE could focus on IT, cloud, and software products and services, while HP stayed with the company’s personal computer and printer business. Latest annual revenue: $27 billion

Mondelez International was formed Oct. 1, 2012, as a spinoff from Kraft Foods. Mondelez was structured to focus on the high growth international snacks and confections segment of Kraft Foods, while the remainder company—Kraft Foods Group, which later merged with Heinz in 2015—was to focus on grocery products for the North American market. Latest annual revenue: $25.9 billion.  See the full list.
