Bertucci's sought protection from creditors under Chapter 11 of bankruptcy law, which usually allows a company to stay in business while it works out a turnaround plan.
Last month, the Bertucci's in Wellesley closed its doors.
The company noted that there is also an asset purchase agreement with Right Lane Dough Acquisitions to purchase substantially all of Bertucci's assets and take on certain liabilities.
The chain's filing says it already has a buyer, identified as Right Lane Dough Acquisitions LLC, which DE records show was formed on April 3.
"Today's filing is expected to be seamless for Bertucci's guests, trading partners and vendors, and result in minimal disruption to its operations, allowing us to strengthen the company's financial structure and position it for significant future growth", said Brian Wright, CEO.
"We are grateful for the service and loyalty of our team members and are looking forward to focusing on a return to Bertucci's roots: authentic, high quality, fresh ingredients that guests and team members alike crave and care about", Wright added.
Bertucci's has 4,200 workers at its 59 locations and the Northborough headquarters.
The chain said it has already slashed more than $5 million in costs through job cuts, lease concessions and other moves since the start of 2017.
There are Bertucci's in Amherst, Andover, Attleboro, Beverly, Braintree, Brockton, Cambridge, Canton, Chelmsford, Framingham, Hingham, Holliston, Lexington, Longmeadow, Mansfield, Marlborough, Medford, Needham, Newton, North Andover, Norwood, Peabody, Plymouth, Randolph, Reading, Swampscott, Taunton, Waltham, Wayland, West Roxbury, West Springfield, Westborough and Woburn. Brian Wright will continue to serve as CEO, and Brian Connell will continue to serve as CFO.
The chain has been trying to lure diners with its new Express Lunch, which promises to bring orders within 15 minutes.
