Qdoba
Qdoba also found itself in deep trouble. Founded in 1995, the chain was initially doing very well, but after ten years, their sales started to drop. Jack in the Box used to own Qdoba but eventually sold it to Apollo Global Management in 2017.
The sudden decrease in sales has to do a lot with health scares, as fewer and fewer people trust the chain. There are currently 700 locations across the U.S., with more of them closing every year.
