Collins Foods plans to take control of Naugles.

The Los Angeles restaurant operator said that it intends to increase its stake in Fullerton-based Naugles Inc. to 51% within the next several months. The disclosure comes one week after Collins increased its holdings in the Mexican fast-food chain to 41.2% with the purchase of a 36.2% block of shares from Naugles’ former chairman, Harold Butler. Collins will buy newly issued Naugles common stock directly from the company rather than on the open market, said Richard P. Bermingham, president of Collins.
