    Quarterly and Year-to-Date Earnings

    Harvey L. Karp, Chairman of Mueller Industries, Inc. (NYSE: MLI), today
announced the Company's results for the second quarter and first-half period
ended June 26, 2004. For the second quarter of 2004, earnings per diluted share
were 73 cents compared with 24 cents in the second quarter of 2003. Net income
was $27.0 million for the second quarter of 2004 compared with $9.0 million for
the second quarter of fiscal 2003. Net sales for the three months ended June 26,
2004, were $380.8 million compared with net sales of $248.2 million for the same
quarter of last year.

    Net sales in the first half of 2004 were $726.8 million compared with net
sales of $480.2 million in the 2003 period. Year-to-date, net income was $45.0
million, or $1.22 per diluted share, compared with $12.9 million, or 35 cents
per diluted share, for the same period last year.


    Financial Highlights

    Regarding the results, Mr. Karp said, "Mueller's second quarter of 2004
clearly demonstrated our Company's ability to leverage the benefits of favorable
market conditions."

     * "Operating income increased to $38.7 million for the second quarter of
       2004 which compares with $11.5 million in the second quarter of 2003.
     * "Pounds of product shipped increased 13 percent to 198.5 million in the
       second quarter of 2004 compared with 175.5 million for 2003.
     * "Gross profit increased more than 70 percent to $77.1 million in the
       second quarter of 2004 compared with $44.8 million in the second quarter
       of 2003.
     * "Our Standard Products Division posted operating earnings of $37.2
       million in the second quarter, compared with $11.9 million in the second
       quarter of 2003. Standard Products Division's net sales were $278.9
       million for second quarter, compared with $178.9 million for 2003.
       Operating results increased on the strength of higher volume and margins,
       particularly copper tube where spreads returned to year 2000 levels.
     * "Results at our European operations continue to improve on better volume
       and spreads.
     * "Our Industrial Products Division posted operating earnings of $6.3
       million during the quarter on net sales of $105.9 million, which compares
       with operating income of $3.6 million and net sales of $71.6 million for
       the same period a year ago. The earnings of our brass rod business
       increased markedly as margins, volume, and costs improved.
     * "Mueller ended the quarter with $263.7 million in cash and virtually no
       debt.
     * "Our current ratio remains excellent at 4.4 to 1 and our working capital
       is $519.9 million.
     * "Capital expenditures totaled $8.8 million during the first half of 2004.
       For the fiscal year 2004, we expect capital expenditures to be in the
       range of $20 to $25 million.
     * "Stockholders' equity has grown to $858.8 million, or $24.55 per share."

    Business Outlook

    Discussing the business outlook, Mr. Karp said, "The business outlook
remains good. Housing starts for 2004 will likely exceed the robust level of
1,853,000 starts achieved in 2003. Moreover commercial construction, an
important market for our products, is improving along with our national economy.
Interest rates have recently ticked up, but by historical standards are quite
low. And the National Association of Home Builders has forecasted that 2005 will
be another outstanding year for the housing industry."
