             MUELLER INDUSTRIES, INC. REPORTS FIRST QUARTER RESULTS

    MEMPHIS, Tenn., April 21 /PRNewswire-FirstCall/ --

    Quarterly Earnings

    Harvey L. Karp, Chairman of Mueller Industries, Inc. (NYSE: MLI), today
announced the Company's results for the first quarter of 2005. Net income for
the first quarter was $15.2 million, or 41 cents per diluted share, which
compares with $18.0 million, or 49 cents per diluted share, for the first
quarter of fiscal 2004. Net sales for the three months ended April 2, 2005 were
$401.7 million, compared with net sales of $346.0 million for the first quarter
of 2004. The current period includes approximately $5.0 million pre-tax of
additional interest expense (approximately 9 cents per diluted share) related
primarily to the Subordinated Debentures issued in the fourth quarter of 2004.

    Financial and Operating Highlights

    Regarding the first quarter financial results, Mr. Karp said, "Mueller's
financial position remains sound.

     * "Operating income increased to $27.2 million, despite lower profitability
       at two of our core product lines, copper tube and brass rod.

     * "Pounds of product shipped by our core product lines totaled 189.4
       million in the first quarter of 2005 compared with 197.6 million for
       2004. The COMEX average copper price in the first quarter of 2005 was
       $1.47 per pound compared with $1.23 per pound for the first quarter of
       2004.

     * "Our Standard Products Division posted operating earnings of $24.6
       million, compared with $25.0 million in 2004. Standard Products
       Division's net sales were $293.9 million for the quarter, compared with
       $249.7 million for 2004. We realized improved results in our copper and
       plastic fittings businesses as well as contributions from acquired
       businesses, that were offset somewhat by decreases in copper tube
       profitability due to lower volumes and spreads.

     * "Operating income at Industrial Products Division was $6.5 million
       compared with $3.4 million (after a $3.9 million impairment charge
       related to Overstreet-Hughes) for the first quarter of 2004. Net sales
       were $111.3 million in the first quarter of 2005 which compares with
       $99.8 million for 2004. Results at our brass rod mill decreased on lower
       volumes and spreads.

     * "Mueller ended the quarter with almost $70 million in cash.

     * "Our current ratio remains excellent at 2.4 to 1 and our working capital
       is $290.9 million.

     * "Capital expenditures totaled $4.8 million during the first quarter of
       2005. For the fiscal year 2005, we expect capital expenditures to be in
       the range of $20 to $25 million.

     * "Stockholders' equity has grown to $365.2 million."



    Business Outlook

    Discussing the outlook, Mr. Karp said, "We are carefully assessing business
conditions with a view toward reacting promptly as need arises. Recently,
interest rates have risen; nonetheless, 30-year fixed rate mortgages are still
very attractive and housing starts and permits are at a historically high level
of 2 million units (seasonally adjusted annual rate). Importantly, commercial
construction is rising and GDP and employment remain relatively strong."

    Mueller Industries, Inc. is a leading manufacturer of copper tube and
fittings; brass and copper alloy rod, bar and shapes; aluminum and brass
forgings; aluminum and copper impact extrusions; plastic fittings and valves;
refrigeration valves and fittings; and fabricated tubular products. Mueller's
