Bob Blessing has announced that he will retire as Chief Development Officer of Chipotle Mexican Grill, Inc., effective October 31, 2013. Leadership of Chipotle's development activities will be assumed by Mark Crumpacker, Chief Marketing Officer, whose title will change to Chief Marketing and Development Officer.

Chipotle Mexican Grill, Inc. approved to amend the certificate of incorporation to eliminate the classification of the Board of Directors and provide for annual elections of all directors, at the shareholders meeting held on May 17, 2013.

Chipotle Mexican Grill, Inc. announced that it is adding premium Patrón margaritas to the menu in its U.S. restaurants. The new margarita is hand-made for each customer using Patrón Silver tequila, triple sec, a blend of fresh lime and lemon juices, and organic agave nectar. The Patrón margarita will be available in about 900 Chipotle restaurants beginning April 29, 2013. Served on the rocks with a wedge of lime, the premium Patrón margarita is a simple recipe using only a few ingredients, and will be offered to customers alongside another margarita option made with Sauza tequila. The Sauza margarita will be available as a house option at a lower price, but will be made using the same recipe as the Patrón version.
