In a research report issued Friday, Canaccord analyst Lynne Collier reiterated a Hold rating on shares of Chipotle Mexican Grill, Inc. (NYSE:CMG), while lowering the price target to $400 (from $440), after the fast food chain confirmed that the norovirus was the culprit of more than 130 cases of illness in a Sterling, VA Chipotle location. Separately, it was highlighted that a restaurant location in Dallas, TX had a rodent problem which was videotaped by a consumer.

Collier commented, “Following additional news events highlighting CMG in a negative light, we are decreasing our estimates as we believe the sales recovery will be at a slower pace than we originally thought. Minor issues, such as the recent norovirus event, will continue to be magnified by the press and social media, providing on-going risk for investors. In terms of valuation, shares presently trade at 15.5x NTM consenus EBITDA estimates.” (To watch Collier’s track record, click here)
