CAL-MAINE FOODS, INC. REPORTS FOURTH QUARTER AND FISCAL 2005 RESULTS

JACKSON, Miss. (August 1, 2005) – Cal-Maine Foods, Inc. (Nasdaq/NM:CALM) today announced financial results for the fourth quarter and fiscal year ended May 28, 2005. For the fourth quarter of fiscal 2005, net sales were $81.5 million compared with net sales of $142.4 million for the fourth quarter a year ago. The Company reported a net loss of $6.6 million, or $0.28 per diluted share, compared with net income of $17.2 million, or $0.70 per diluted share, for the fourth quarter of fiscal 2004.

        For the fiscal year 2005, net sales were $375.3 million compared with net sales of $572.3 million for fiscal 2004. The Company reported a net loss of $10.4 million, or $0.43 per diluted share, compared with net income of $66.4 million, or $2.73 per diluted share, in fiscal 2004.

        Fred Adams, Jr., chairman and chief executive officer of Cal-Maine Foods, Inc., stated, “Beginning in the summer of 2003, the egg industry experienced very strong demand. This demand was related to the high-protein, low-carb diets that were very popular at the time. This strong demand, combined with moderate supply, resulted in record high egg prices for approximately 15 months. However, In the early fall of 2004, this demand trend related to the popular diets faded dramatically. In the meantime, the egg industry had geared up to produce more eggs to meet the strong demand. As a result, during the past nine to 12 months, our industry has experienced an oversupply of eggs resulting in lower prices and losses for the egg industry.

        “Beginning in March 2005, the egg industry has taken action to reduce the size of the laying flocks and the supply of eggs,” added Adams. “At midsummer, U.S.D.A. statistics indicated a reduced flock size that is now more in line with the current demand for eggs. As a result, egg prices have recovered nicely over the last six or seven weeks. We believe the egg industry will continue to adjust supply to be more in line with demand, which should allow the industry to return to profitability.

        “Feed prices in general have been favorable this year compared with the prior year. However, we have witnessed wide swings in corn and soybean prices because of dry conditions in the Midwest and widely varying forecasts. Overall, Cal-Maine is operating efficiently, and we hope to return to profitability in the year ahead,” Adams concluded.

        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 28 states across the southwestern, southeastern, mid-western and mid-Atlantic regions of the United States.
