BusinessWeek reports Denny’s Corp.’s franchisee group has weighed in on a proxy battle between the restaurant chain and a group of dissident stockholders.

The group of investors, who call themselves the Committee to Enhance Denny’s, have criticized what they call the restaurant chain’s “culture of wasteful spending,” its loss of customers to competitor IHOP and the lack of stock ownership by members of the board.

They have pushed board nominees who they say would work to cut costs by $15 million, adjust management’s bonus system and work to reverse weak sales trends at the chain.

Denny’s has fired back over the group’s claims and on Thursday released a letter from Craig Barber, chairman of the Denny’s Franchisee Association, to Denny’s Chairwoman Debra Smithart-Oglesby. The letter disputes the dissident investors’ claims that Denny’s management has not been responsive to its franchisees.

The letter from the association, which represents about 85 percent of the company’s franchised restaurants, said management has taken steps to support franchisees. It did note that the association has not taken a position on the nominees.

Denny’s new business model aims to have 90 percent of its locations run by franchisees
