Doug Pendergast, who headed Krystal Co. from 2012 to 2014 when the fast-food chain relocated its headquarters from Chattanooga to Atlanta, is stepping down from his latest job as president and CEO of the Quiznos sandwich chain.
Katie Scherping, Quiznos chief financial officer, will serve as interim president and CEO.
Company executives said that Pendergast would stay to help with the transition until June 24, but Scherping will take the reigns immediately.
Pendergast joined the Denver-based chain in January 2015, not long after Quiznos emerged from bankruptcy protection following the completion of a financial restructuring. The chain was also shrinking, reaching about 1,000 locations at the end of fiscal 2014, compared with more than 5,000 in 2006.
