CAL-MAINE
FOODS REPORTS THIRD QUARTER FISCAL 2010 RESULTS





JACKSON,
Miss. (March 29, 2010) 3⁄4 Cal-Maine Foods, Inc.
(NASDAQ: CALM) today reported results for the third quarter and nine months
ended February 27, 2010.





Net sales
for the third quarter of fiscal 2010 were $271.2 million compared with net sales
of $270.0 million for the same quarter of fiscal 2009.  The
Company reported net income of $34.5 million, or $1.45 per basic share, for
the third quarter of fiscal 2010 compared with net income of
$30.8 million, or $1.30 per basic share, for the third quarter of
fiscal 2009.





For the
first nine months of fiscal 2010, net sales were $688.1 million compared with
net sales of $715.2 million for the prior-year period.  The Company
reported net income of $46.8 million, or $1.97 per basic share, for
the first nine months of fiscal 2010 compared with net income of
$69.2 million, or $2.91 per basic share, for the year-earlier
period.





“We are
pleased with Cal-Maine’s results for the third quarter of fiscal 2010,” said
Fred Adams, Jr., chairman and chief executive officer of Cal-Maine Foods,
Inc.  “We benefitted from a favorable balance of supply and demand for eggs
during the quarter, and our sales at the retail level were very
good.   Restaurant and other food service sales continued to
reflect weak demand as consumers are not dining out as frequently in this
economic environment.  However, egg product sales were fairly
good.   Our feed costs were also lower for the quarter compared
with the prior-year period, improving our profitability.  Overall, our
management team did a good job and all of our operations are running
smoothly.





“We
continue to see a favorable balance between egg supply and egg demand for the
coming year.  However, feed costs could continue to be volatile,” added
Adams.





For the
third quarter of fiscal 2010, Cal-Maine will pay a cash dividend of
approximately $0.48 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
May 13, 2010, to shareholders of record on April 28,
2010.





Selected
operating statistics for the third quarter of fiscal 2010 compared with the
prior-year period are shown below:
