CAL-MAINE FOODS REPORTS
FIRST QUARTER FISCAL 2011 RESULTS





JACKSON,
Miss. (September 27, 2010) 3⁄4 Cal-Maine Foods, Inc.
(NASDAQ: CALM) today announced results for the first quarter of fiscal 2011
ended August 28, 2010.





For the
first quarter of fiscal 2011, net sales were $190.4 million, compared with net
sales of $187.7 million for the first quarter of fiscal
2010.  The Company reported net income of $4.8 million, or
$0.20 per basic and diluted share, for the first quarter of fiscal 2011
compared with a net loss of $3.8 million, or $0.16 per basic and
diluted share, for the year-earlier period.  The financial results for
the first quarter of fiscal 2011 include a business interruption insurance
gain recognition of approximately $2.6 million, net of income taxes,
related to fire damage sustained at the Company’s Farwell, Texas, facility
on July 9, 2009.





Fred Adams, Jr., chairman and chief
executive officer of Cal-Maine Foods, Inc., stated, “We are pleased with our
financial and operating results for the first quarter, marking a solid start to
fiscal 2011 for Cal-Maine Foods.  Our improved sales were
primarily driven by increased consumer demand for our value-added specialty
eggs, which carry higher retail sales prices.  Overall, we experienced
a modest improvement in both volume and average selling prices compared with the
first quarter of fiscal 2010.  Our retail business has remained very
steady, while our food service sales have been affected by reduced restaurant
traffic, as consumers are not dining out as frequently.





“The recent nationwide egg recall had
minimal effect on Cal-Maine’s results this quarter.  While egg prices
initially moved higher in late August, prices have since dropped back below
levels prior to the recall.  Consumer demand for eggs has also dropped
off since the recall; however, it is still too soon to predict
the long-term effect on demand trends.





“Cal-Maine’s
operations have continued to run efficiently and we benefitted from lower feed
costs in the first quarter of fiscal 2011 compared with a year ago,” added
Adams.  “However, corn prices have risen recently and will likely
remain volatile in the year ahead.”





For the
first quarter of fiscal 2011, Cal-Maine will pay a cash dividend of
approximately $0.067 per share to holders of its common and Class A common
stock.  The amount paid could vary slightly based
on the amount of outstanding shares on the record date.  The
dividend is payable November 11, 2010, to shareholders of record
on October 27, 2010.





Selected operating statistics for the
first quarter of fiscal 2011 compared with the prior year period are shown
below:
