Cochran joined Cracker Barrel in 2009 as executive vice president and chief financial officer. She was named as its president and chief operating officer the following year, before moving to her current job in September 2011.

Dollar General shares fell 94 cents, or 2 percent, to $47 in morning trading. Its shares peaked for the past year at $56.04 in July. They fell as low as $38.85 last December.
