Rosen said: “It has been an incredible four years at FAT Brands — filled with numerous strategic acquisitions, assuming the role of co-CEO in 2023, and most recently, the IPO [initial public offering] of Twin Hospitality Group. I look forward to continuing to help drive the company forward, maintaining a consulting role focused on debt/capital markets.”

FAT Brands owns and franchises more than 2,300 restaurant units worldwide across a range of dining segments: quick-service, fast casual, casual and polished casual formats.

Its portfolio includes brands such as Round Table Pizza, Fatburger, Marble Slab Creamery and Bonanza Steakhouses

In early 2025, the company opened a tri-branded location in Roanoke, Texas, combining Great American Cookies, Marble Slab Creamery and Pretzelmaker in a single venue.
