Ells will need all the help he can get for fixing the company.

Since the food safety scare, Wall Street has been losing faith in the company. The value of the chain’s stock has fallen by 34% in the last year.

The move to entrust Ells with even more authority over the company’s direction didn’t inspire confidence in everyone watching. “He just doesn’t have the skill set to run a big company like this, and he doesn’t have the skill set to turn it around, either,” says Howard Penney, a consumer analyst at Hedgeye Risk Management.

Penney said Chipotle’s three major missteps were taking too long to admit there was a problem, giving away millions of dollars of free food to try and fix it, and continuing to build more restaurants in spite of it.

That’s going to be some challenge for Ells to fix.
