FAT Brands has completed its previously announced acquisition of Global Franchise Group (GFG), a move that adds five new restaurant concepts to its portfolio.

The deal closed nearly a month after the company signed an agreement to acquire GFG from Serruya Private Equity and Lion Capital for $442.5m.

As a strategic brand management company, GFG focused on franchising and operating quick-service restaurant (QSR) concepts, including Round Table Pizza, Great American Cookies, Marble Slab Creamery, Hot Dog on a Stick and Pretzelmaker.

With the deal complete, FAT Brands’ portfolio now includes more than 2,000 franchised and company-owned restaurants globally.

The deal is also expected to increase the company’s annual EBITDA by around $40m, to between $55m and $60m, as well as boost annual revenues to more than $100m.

FAT Brands CEO Andy Wiederhorn said: “This acquisition is our largest deal yet, and further diversifies our iconic restaurant portfolio into new restaurant segments and categories. As our acquisitions have grown from small chains to global restaurants, FAT Brands is poised to better position itself as a multi-concept operator in the franchise restaurant business.

“Serruya Private Equity and Lion Capital were excellent partners in bringing this transaction to completion. Serruya has been a longtime supporter of our vision and we are grateful to be working with partners who share our enthusiasm for this diverse market.”

FAT Brands funded the transaction by paying $350m in cash, with the remaining amount provided through a combination of Series B preferred stock and common stock.

Recently, the company signed a deal to develop 50 co-branded Fatburger and Buffalo’s Express locations in Mexico.
