Chipotle Mexican Grill Inc (CMG  ) reported second-quarter financial results on Wednesday. Here's a rundown of the report and a look at why shares are getting cooked after the close.

Q2 Earnings: Chipotle said second-quarter revenue increased 13.6% year-over-year to $2.51 billion, which missed the consensus estimate of $2.53 billion, according to Benzinga Pro. The company reported quarterly earnings of $12.65 per share, which beat analyst estimates of $12.31 per share.

Food, beverage and packaging costs in the second quarter were 29.4% of total revenue, a decrease of about 100 basis points year-over-year, driven by lower avocado costs.

Chipotle said it opened 47 new restaurants in the quarter, and 40 of those locations included a Chipotlane.
