    Mueller Industries, Inc. Reports Fourth Quarter and Fiscal 2003 Earnings



     MEMPHIS, Tenn., Feb. 3 /PRNewswire-FirstCall/ -- Harvey L. Karp, Chairman
of Mueller Industries, Inc. (NYSE: MLI), announced today that Mueller's earnings
from continuing operations for fiscal 2003 were $1.19 per diluted share,
compared with the $1.92 reported a year ago. Income from continuing operations
for the year was $44.2 million, compared with $71.2 million for the prior year.
Net sales for the twelve-month period were $999.1 million, versus $953.0 million
in 2002. Net income for 2003 was $45.4 million. For 2002, net income of $78.0
million includes a gain on the disposition of Utah Railway Company of $21.1
million and a loss on the disposition of French manufacturing operations of
$13.4 million, both net of income taxes.

     For the quarter ended December 27, 2003, income from continuing operations
was $11.0 million, or 30 cents per diluted share, which compares with $8.8
million, or 24 cents per diluted share for the same period a year ago. Net sales
for the three months ended December 27, 2003, were $267.8 million, compared with
net sales of $216.1 million for the 2002 period.


     Financial and Operating Highlights
     Regarding the 2003 results, Mr. Karp said:

     * "Mueller ended the year with $255.1 million in cash.

     * "We're virtually debt free, as cash-on-hand significantly exceeds total
       debt of $14.3 million.

     * "Our current ratio remains excellent at 5 to 1 and our working capital is
       $456.8 million.

     * "Cash from continuing operations was $73.4 million during 2003. We
       continue to generate positive cash flow; should our operating results
       improve in 2004, we expect cash flow to increase significantly.

     * "Capital expenditures totaled $27.2 million during 2003. For the fiscal
       year 2004, we expect capital expenditures to be approximately $25
       million, which is less than depreciation.

     * "We invested $10.8 million in acquisitions in early 2003, increasing our
       interest in Conbraco Industries, Inc.

     * "Stockholders' equity has grown to $814.9 million, or $23.77 per share.

     * "Pounds of product shipped were 695.8 million in 2003 compared with 694.0
       million for 2002.

     * "As core product line spreads narrowed early in the year, gross profit
       and operating income bottomed out in the first quarter, then steadily
       improved throughout the year. Selling, general, and administrative
       expenses increased over 2002 primarily due to higher distribution costs,
       employee benefit plan costs, and increased provision for doubtful
       accounts.

     * "Our Standard Products Division posted operating earnings of $54.1
       million, compared to $79.0 million in 2002. Standard Products Division's
       net sales were $717.6 million for the year, compared with $679.3 million
       for 2002. Operating results were negatively impacted by lower spreads in
       copper tube. Spreads bottomed out in the first quarter of 2003 and
       improved modestly throughout the balance of the year.

     * "Our Industrial Products Division posted operating earnings of $11.7
       million during the year on net sales of $292.0 million, which compares
       with operating earnings of $20.4 million on net sales of $279.6 million
       for 2002."

    Discussion of Income Taxes

    During 2003, the Company recognized a deferred income tax benefit related to
a 1999 tax operating loss that resulted from the sale of a subsidiary in that
tax year. Without this deferred income tax benefit, the Company's income from
continuing operations for 2003 would have been approximately $34.9 million, or
95 cents per diluted share.

    During 2002, the Company sold the Utah Railway Company. This transaction
generated a capital gain for income tax purposes. Without the income tax
benefits related to the transaction, the Company's income from continuing
operations for 2002 would have been approximately $58.5 million, or $1.58 per
diluted share.


    Business Outlook for 2004

    Discussing the outlook for the next fiscal year, Mr. Karp said, "The U.S.
housing industry is poised for another strong year in 2004. Housing starts in
2003 totaled 1.8 million units, and housing economists are predicting a
similarly high number for 2004. In addition, mortgage rates remain
extraordinarily attractive and housing affordability statistics show that more
people than ever can afford to buy homes.

    "Moreover, commercial construction, which for the past several years has
been lagging, is expected to rebound in 2004. This is an important market for
Mueller, as it absorbs many of our high value-added products.

    "All of the above is in the context of an improving national economy, which,
in the third quarter of 2003, experienced the highest quarterly growth rate in
the past 20 years."
