CAL-MAINE FOODS, INC. REPORTS FIRST QUARTER FISCAL 2008 RESULTS

JACKSON, Miss. (October 1, 2007) ¾ Cal-Maine Foods, Inc. (NASDAQ: CALM) today announced results for its first quarter of fiscal 2008 ended September 1, 2007.

For the first quarter of fiscal 2008, net sales were $178.6 million, compared with net sales of $115.3 million for the first quarter of fiscal 2007. The Company reported net income of $18.0 million, or $0.76 per basic and diluted share, for the first quarter of fiscal 2008 compared with a net loss of $5.4 million, or $0.23 per basic and diluted share, for the year-earlier period.

Fred Adams, Jr., chairman and chief executive officer of Cal-Maine Foods, Inc., stated, “Our sales volumes and overall profitability were strong for the first quarter of fiscal 2008. We benefited from excellent egg prices during a quarter that is seasonally weak. We were pleased with our overall operating efficiency and ability to achieve favorable margins in spite of higher feed costs. Demand for eggs was good from both retail and food service customers in the U.S. and we also experienced strong export sales to Europe and Japan. USDA statistics indicate that the overall egg supply will be moderate in the months ahead.”

Cal-Maine Foods, Inc. is primarily engaged in the production, grading, packing and sale of fresh shell eggs. The Company, which is headquartered in Jackson, Mississippi, currently is the largest producer and distributor of fresh shell eggs in the United States and sells the majority of its shell eggs in approximately 29 states across the southwestern, southeastern, mid-western and mid-Atlantic regions of the United States.
