Dunkin’ Brands Group Inc., operator of the Dunkin’ Donuts coffee chain, on Wednesday filed to raise as much as $400 million in an initial public offering to pay down debt.

JPMorgan Chase, Barclays Capital and Morgan Stanley will underwrite, according to a regulatory filing. Dunkin’ didn’t disclose the pricing per share or an offering date. The stock will be listed on the Nasdaq Stock Market. The new ticker will be DNKN.

Dunkin’ was taken private five years ago by private equity firms Bain Capital, Carlyle Group and Thomas H. Lee Partners in a deal valued at $2.43 billion. The chain has picked a good time for an IPO as consumers are feeling more confident and spending more money eating out, said Jack Russo, of Edward Jones & Co. in St. Louis.

“The food-service environment in general has improved over the last six to nine months,” the analyst said.

Dunkin’, based in Canton, Mass., is also seeking to enter the growing single-cup coffee business by partnering with Green Mountain Coffee Roasters Inc. to make K- Cups for Green Mountain’s Keurig brewing machine.
