Dunkin' Brands – Shares of the restaurant operator dropped nearly 3 percent after the company reported revenue that missed estimates.

For quarterly earnings, Dunkin' Brands beat estimates by three cents.
Chipotle Mexican Grill – Chipotle stock surged a whooping 11 percent after the restaurant chain reported adjusted quarterly profit of $1.72 per share, beating the consensus estimate of $1.37. Chipotle benefited from increased customer traffic during the quarter and a spike in online orders.
