Del Taco has closed its previously announced recapitalization in advance of the planned acquisition of the company by Levy Acquisition Corp., a blank check company formed in October 2013 for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar business combination.

Restaurateur Larry Levy, the CEO and chairman of the board of LAC, together with his family and a group of new investors have made a private investment of $120 million in the common stock of Del Taco and now own approximately 46 percent of the quick-service concept. Levy has assumed the chairmanship of Del Taco.
