Roark Capital Group bolsters its restaurant portfolio with the fast-casual sandwich concept.  

Atlanta-based private equity firm Roark Capital Group acquired a majority interested in Jimmy John’s Sandwiches. No management changes are planned and terms of the deal were not disclosed.

Previous partners Weston Presido, a San Franciso-based private equity firm, sold its minority stake as part of the agreement.

Jimmy John’s Sandwiches, based in Champaign, Ill., operates more than 2,500 fast-casual sandwich shops in the U.S. that generate more than $2 billion in annual revenues, per a release announcing the deal. The Chicago Tribune speculates the new investment with Roark sets the company up for international expansion.
