Chipotle Mexican Grill’s executive team boosted Wall Street’s confidence in the company by characterizing the chain’s customers as confused and predicting they would all return by next year. The occupants of the Denver-based chain’s C-Suite discussed public reaction and corporate responses to a string of Salmonella, E. coli and norovirus outbreaks linked to their restaurants on Jan. 13 at the annual ICR Conference in Florida. The invitation-only event is produced by ICR Inc., a New York City communications and advisory firm. The executives’ reassurances buoyed Chipotle’s stock, keeping it above the $400 mark as of the end of business Jan. 14. The company’s value doubled in the past five years, its stock topping $750 in 2015. But the series of six confirmed foodborne illness outbreaks that sickened more than 500 people across 10 states left Chipotle’s stock value down by $6 billion at one point late in the year.
