           MUELLER INDUSTRIES, INC. REPORTS SECOND QUARTER RESULTs

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

    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 of 2005. Net income for
the second quarter was $17.2 million, or 46 cents per diluted share, which
compares with $27.0 million, or 73 cents per diluted share, for the second
quarter of fiscal 2004. Net sales for the three months ended July 2, 2005 were
$410.5 million, compared with net sales of $380.8 million for the second quarter
of 2004. The current period includes approximately $4.8 million pre-tax of
interest expense (approximately 9 cents per diluted share) related primarily to
the Subordinated Debentures issued in the fourth quarter of 2004.

    Year-to-date, the Company earned $32.4 million, or 87 cents per diluted
share, on net sales of $812.2 million. This compares with net income of $45.0
million, or $1.22 per diluted share, on net sales of $726.8 million for the
first half of 2004.

    Financial and Operating Highlights

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

     - "Operating income decreased to $25.3 million, as the precipitous increase
       in copper prices led to reduced margins in our copper tube and brass rod
       product lines. Trading as high as $1.69 per pound in June, the COMEX
       copper price for the second quarter of 2005 averaged $1.53 per pound
       compared with $1.23 per pound for the second quarter of 2004.

     - "Pounds of product shipped by our core product lines totaled 182.2
       million in the second quarter of 2005 compared with 198.5 million for
       2004.

     - "Our Standard Products Division posted quarterly operating earnings of
       $23.2 million, compared with $37.2 million in 2004. Standard Products
       Division's net sales were $302.4 million for the quarter, compared with
       $278.9 million for 2004. We realized solid results from our copper and
       plastic fittings businesses. However, operating profit declined on lower
       volume and margins in our copper tube business. The volatility of copper
       caused some of our customers to scale back their purchases.

     - "Operating income at Industrial Products Division was $7.3 million
       compared with $6.3 million for the second quarter of 2004. Net sales were
       $110.9 million in the second quarter of 2005 which compares with $105.9
       million for 2004. Results at our brass rod mill decreased on lower
       volumes, while other product lines reported improved results.



     - "Mueller ended the quarter with $69 million in cash; the higher balances
       of accounts receivable and inventories caused by rising copper prices
       were readily funded with cash on-hand.

     - "Our current ratio remains excellent at 2.5 to 1 and our working capital
       is $307.8 million.

     - "Capital expenditures totaled $8.9 million during the first half 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 $375.4 million."

    Business Outlook

    Discussing the outlook, Mr. Karp said, "The housing industry continues to
show strength. Housing starts are approximately 4 to 5 percent ahead of last
year. Non-residential construction is also growing, yet remains well below its
peak level in 2000. Interest and mortgage rates are at very attractive levels
and the general economy is growing at a robust rate. And more specifically, we
have noted recent improvement in margins in our copper tube business, which is
our largest business unit by far."
