Fred Adams, Jr., chairman and chief executive officer of Cal-Maine Foods, Inc., stated, "The results for the fourth quarter reflect good demand for eggs and strong egg prices. The overall supply of eggs was slightly lower than the same period last year, which contributed to a more favorable market balance. Feed costs continued to be very high, reflecting the rising costs of corn and soybean meal.

"For fiscal 2008, our results reflect very good egg prices, record high feed costs, and a solid performance by the Cal-Maine management team. As we look ahead, we see continued strong demand for eggs, a slightly higher, but manageable, egg supply, and further volatility with respect to corn and soybean meal prices. All of our operations are running smoothly, and we are optimistic about Cal-Maine's business for the year ahead."

For the fourth quarter of fiscal 2008, Cal-Maine will pay a cash dividend of approximately $.516 per share to holders of its common stock. A cash dividend of approximately $.49 per share will be paid to holders of its Class A common stock, which represents 95 percent of the amount paid to holders of common stock. The amount paid could vary slightly based on the amount of outstanding shares on the record date. The dividend is payable August 14, 2008, to shareholders of record on July 30, 2008.
