Exhibit 99.1

    MUELLER INDUSTRIES, INC. REPORTS FOURTH QUARTER AND FISCAL 2006 EARNINGS

    MEMPHIS, Tenn., Feb. 6 /PRNewswire-FirstCall/ -- Harvey L. Karp, Chairman of
Mueller Industries, Inc. (NYSE: MLI), announced today that Mueller's income from
continuing operations for fiscal 2006 was $148.9 million, or $4.00 per diluted
share, which compares with $89.2 million, or $2.40 per diluted share, for 2005.
Net sales for 2006 were $2.51 billion compared with $1.73 billion in 2005. The
increase in net sales is primarily due to the increased cost of copper, the
Company's principal raw material, which is generally passed through to customers
by changes in selling prices.

    For the fourth quarter of 2006, the Company's net income was $5.2 million,
or 14 cents per diluted share, on net sales of $544.2 million. This compares
with net income of $35.8 million, or 97 cents per diluted share, on net sales of
$483.6 million for the quarter ended December 31, 2005. The fourth quarter of
2006 includes a pre-tax charge of approximately $14.2 million (or 26 cents per
diluted share after tax) to write-down inventories to the lower-of-cost-
or-market that resulted from falling copper prices. Additionally, the fourth
quarter results were adversely impacted by lower unit volumes due to the much
anticipated "correction" in the residential construction market.

    Financial and Operating Highlights
    Mr. Karp said:

    * "The COMEX average price of copper was $3.19 per pound in the fourth
      quarter of 2006 and closed the year at $2.85 per pound. During 2006,
      copper had reached the price of $4.08 per pound, which is a historic high.

    * "Our current ratio remains strong at 3.0 to 1 and our working capital is
      $520.7 million, of which $200.5 million is cash on hand.

    * "Cash provided by operating activities was $64.5 million in 2006 compared
      with $106.1 million during 2005. Additional investments in accounts
      receivable and inventories were required because of higher raw material
      costs.

    * "For the full year, our Plumbing & Refrigeration segment posted operating
      earnings of $197.4 million on net sales of $1.72 billion which compares
      with operating earnings of $125.5 million on net sales of $1.28 billion in
      2005. During the fourth quarter of 2006, market conditions for our core
      product lines remained challenging; unit volumes, particularly copper
      tube, were down substantially compared with the fourth quarter of 2005.
      Operating margins were curtailed during the fourth quarter due to weakness
      in demand, price reductions, and higher unit costs on lower production
      volume.

    * "Our OEM segment posted operating earnings of $44.8 million during the
      year on net sales of $835.3 million, which compares with operating
      earnings of $27.0 million on net sales of $460.3 million for 2005.
      Included in the OEM segment is our Chinese joint venture which reported
      total operating income of $6.4 million for 2006.

    * "Of the $14.2 million inventory write-down, $11.2 million occurred in
      Europe where FIFO inventory accounting is employed. In the U.S., LIFO
      inventory accounting is primarily used for the cost of the copper
      component in inventory, which moderates swings in inventory valuations.

    * "Capital expenditures during 2006 totaled $41.2 million of which $17.9
      million relates to our Chinese joint venture."



    Business Outlook for 2007

    Regarding the outlook for 2007, Mr. Karp said, "After more than five years
of vigorous growth, the housing industry is experiencing the widely predicted
'correction.' The 'correction' is underway but may have already bottomed-out.

    "We note that the inventory of unsold new homes is declining, while building
permits, the key indicator of future business, increased at the end of 2006.
Also, mortgage rates are near historical lows and demographic factors are
positive for the housing market.

    "We expect the commercial and retail sectors of Mueller's business will
perform well during the year."

    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;
