             Mueller Industries, Inc. Reports Second Quarter Results

      MEMPHIS, Tenn., July 24 /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 2007. Net income for
the second quarter was $36.4 million, or 98 cents per diluted share,
constituting the third highest quarter in the Company's history. This compares
with $58.8 million, or $1.57 per diluted share, for the extraordinary second
quarter of fiscal 2006, which was the Company's best quarter ever. Net sales for
the three months ended June 30, 2007 were $772.6 million, compared with net
sales of $779.7 million for the second quarter of 2006.

      Year-to-date, the Company earned $55.3 million, or $1.49 per diluted
share, on net sales of $1.38 billion. This compares with net income of $92.1
million, or $2.48 per diluted share, on net sales of $1.33 billion for the first
half of 2006.

      Earnings and sales for the second quarter were affected by the decline in
the residential construction sector, which saw housing starts down approximately
25 percent compared with last year.

      However, the commercial construction market continues to strengthen and
has increased by approximately 18 percent over last year. The Company's profit
margins in the commercial construction sector have historically been better than
in the other markets the Company serves.

      Financial and Operating Highlights

      Regarding the second quarter of 2007, Mr. Karp said:

      --    "Mueller ended the quarter with almost $250 million in cash; our
            current ratio remains excellent at 2.48 to 1 and our working capital
            is $557.3 million.

      --    "The COMEX average price of copper was $3.46 per pound in the second
            quarter of 2007, which compares with $3.37 per pound in the second
            quarter of 2006.

      --    "Our Plumbing & Refrigeration segment posted operating earnings of
            $51.7 million on net sales of $455.5 million which compares with
            operating earnings of $78.3 million on net sales of $551.2 million
            in the second quarter of 2006. Our European businesses were
            profitable on the strength of our trading activities.

      --    "Our OEM segment posted operating earnings of $18.0 million during
            the second quarter of 2007 on net sales of $322.2 million, which
            compared with operating earnings of $21.5 million on net sales of
            $242.1 million for the same period in 2006.

      --    "Selling, general, and administrative expense was $39.0 million in
            the second quarter of 2007 which is comparable to the same period of
            2006.

      --    "Capital expenditures during the first half of 2007 totaled $15.6
            million. We expect to invest between $30 and $40 million for capital
            expenditures during 2007."


      Business Outlook for 2007

      Regarding the outlook for 2007, Mr. Karp said, "The residential
construction sector remains weak, although the rate of decline has subsided. We
believe the housing market is near the bottom, and will begin to improve in the
first half of 2008. Positive factors include low mortgage rates, high
employment, an expanding economy, and population growth. Also, we expect the
commercial construction market to remain strong."
