This isn't time first Chipotle has hit a bump in the road. The company posted a meager 2.2 percent gain at established restaurants in 2009, leading to questions that the burrito chain may have plateaued after double-digit growth in two of the previous three years. But that, it turned out, was a rare off year. Chipotle's sales surged 17 percent in 2014 and the company's shares still trade at about 32 times earnings, second only to Starbucks among restaurant companies in the S&P 500.
