Ignite says it will fund the acquisition through a $50 million upsizing of the company’s existing credit facility. The deal is expected to close in late second quarter. KeyBanc Capital Markets provided financial advice to Ignite. Romano’s Macaroni Grill, which opened its first restaurant in 1988, currently owns and operates 186 units and franchises five units across 36 states.
