Chipotle Mexican Grill shares edged lower in light trading after news broke about one of its Billerica, Massachusetts, restaurants shutting down after employees became ill. The store closed voluntarily, the Massachusetts Department of Health told NBC Boston.
"After learning that four of our employees were not feeling well, our restaurant in Billerica, Mass., was closed for a full sanitization," Chipotle said, in a statement late Tuesday. "We do not know know if the employees are ill with Norovirus and no customers illnesses are connected to this restaurant."
Shares of natural pet food brand Blue Buffalo popped after the bell after reporting better-than-expected earnings in the fourth fiscal quarter. The company reported sales of $265.2 million, an 11.4 percent increase and above the $259.2 million expected by Wall Street, according to the Associated Press.
The company said it would invest in two new manufacturing centers and a research-and-development center in the next three years, according to a company release.
