Guernsey Holdings is a Las Vegas, Nevada multi-brand quick serve franchise investment group headquartered at 304 S Jones Blvd, Suite 5700. Founder and managing partner Mike James launched the platform in 2021 and quickly scaled Sonic Drive-In operations into one of the brand's largest franchise partners while later adding a Zaxby's equity portfolio, with dedicated brand presidents and operating partners overseeing each concept. The firm emphasizes operational turnaround, real estate development and capital allocation across multi-state markets, with Southern California and New York offices supporting the Las Vegas headquarters. Concepts are Sonic Drive-In and Zaxby's. Guernsey Holdings operates under franchise agreements and does not own those consumer brands. Restaurants operate as a multi-state U.S. quick serve portfolio spanning Sun Belt, Midwest and Pacific Northwest markets. Locations are quick serve and serve breakfast, lunch and dinner with American, burger, chicken, ice cream and yogurt and sandwich menus. Size and seating vary by concept, with a typical footprint around 1,500 square feet and about 50 seats.

The Restaurant Enterprise Index focuses primarily on companies with a substantial role in restaurant operations. Investment firms, financial sponsors, and other ownership partners are generally not included unless they also play a meaningful operating role; an otherwise qualifying entity may also be omitted when sufficient reliable information is unavailable.
The ownership hierarchy follows the entity structure from the bottom up, showing the profiled entity in relation to its parent organizations, including its ultimate parent. When the entity owns or operates concepts beneath it, up to three are displayed.
