Chipotle Mexican Grill Inc. shares rose after its sales beat expectations and the burrito chain forecast an acceleration in the fourth quarter.

Same-store sales growth — a gauge of how restaurants open for more than year are performing — was 5% in the third quarter, higher than the 4.4% analysts polled by Bloomberg had anticipated. For the fourth quarter, the company is anticipating a more aggressive expansion clip, guiding to a mid- to high-single digit range.
