Remember Jared Fogle, the guy who lost a bunch of weight by exercising and eating only Subway sandwiches? Well, he was just dropped as Subway’s spokesman because of his involvement in a child pornography investigation. 

But the company has a lot more to worry about than losing Jared: company co-founder and CEO Fred DeLuca is fighting leukemia, it has yet yet to adjust to the demands of millennials and business isn’t doing so well. Last year, U.S. sales dropped 3.3 percent — the worst drop among big fast-food chains. That might be because of over-expansion.

“Their competitors sometimes turn out to be other Subway owners who could be right down the block from them,” says Susan Berfield who wrote about Subway’s trouble for Bloomberg Businessweek. 

It’s Subway’s 50th year in business, but the sandwich restaurant is probably not where it wants to be to celebrate. However, it’s worth noting that even though sales might be dropping, Subway is still a huge business and the largest fast-food chain in the world.
