                        MUELLER INDUSTRIES, INC. REPORTS
                    FOURTH QUARTER AND FISCAL 2008 EARNINGS

     Harvey L. Karp, Chairman of Mueller Industries, Inc. (NYSE: MLI), announced
today that Mueller's net income for the fiscal year ended December 27, 2008 was
$80.8 million, or $2.17 per diluted share, which compares with $115.5 million,
or $3.10 per diluted share, for 2007.  Net sales for 2008 were $2.56 billion
compared with $2.70 billion in 2007.

     For the fourth quarter of 2008, the Company's net income was $7.8 million,
or 21 cents per diluted share, on net sales of $435.4 million.  This compares
with net income of $28.8 million, or 78 cents per diluted share, on net sales of
$621.7 million for the fourth quarter of 2007.  During the fourth quarter of
2008, the Company recognized several special items that, in aggregate, decreased
net income by $2.0 million, or 5 cents per diluted share.  The special items are
described below.

Financial and Operating Highlights

     Mr. Karp said:

     -  "The reduction in net sales was primarily due to lower unit shipments as
        well as the lower average cost of copper, the Company's principal raw
        material, which is generally passed through to customers by changes in
        selling prices.  The price of copper was volatile during 2008 and
        declined substantially during the fourth quarter; the Comex average
        price of copper during the fourth quarter was $1.75 per pound in 2008
        versus $3.25 in 2007.

     -  "Cash provided by operating activities was $180.9 million in 2008
        compared with $185.8 million during 2007.

     -  "For the full year, our Plumbing & Refrigeration segment posted
        operating earnings of $106.8 million on net sales of $1.40 billion which
        compares with operating earnings of $178.4 million on net sales of $1.57
        billion in 2007.  Operating earnings decreased primarily due to lower
        shipment volumes and higher per unit conversion costs on lower
        production volumes.

                                   Page 1 of 7


     -  "Our OEM segment posted operating earnings of $45.3 million during the
        year on net sales of $1.18 billion, which compares with operating
        earnings of $38.2 million on net sales of $1.14 billion for 2007.  Weak
        demand in the later part of the year reduced shipments.

     -  "Our current ratio remains strong at 3.7 to 1 and our working capital
        is $553.2 million, of which over $275 million is cash on hand.

     -  "As of year end, our financial leverage was modest with a debt to total
        capitalization ratio of 20.7 percent.  During 2008, we purchased
        approximately $149.0 million of our outstanding 6% Subordinated
        Debentures at discounts off of face value.  Gains attributable to these
        repurchases totaled $19.1 million in the fourth quarter and $21.6
        million for the year.

     -  "The special items referred to above are: (i) an impairment charge
        totaling $18.0 million to reduce the carrying value of goodwill, (ii)
        additional environmental provisions of $15.0 million pertaining to
        estimated environmental settlements and obligations, (iii) a nontaxable
        gain of $19.1 million related to the repurchase of debentures, (iv) LIFO
        income of $14.9 million due to reduction of the quantities of LIFO
        inventory, and (v) a charge of $4.9 million to write-down certain
        inventories to the lower-of-cost-or-market that resulted from falling
        copper and other metal prices.  The goodwill impairment is an estimate
        that will be adjusted after valuation procedures, including third party
        valuations, are completed as required by generally accepted accounting
        principles.

     -  "Our return on average equity was 11.5 percent for 2008 which compares
        with 17.8 percent for 2007.

     -  "Total stockholders' equity was $700.7 million which equates to a book
        value per share of $18.86 of which $7.51 per share is in cash.
        Stockholders' equity was reduced by the impact of foreign currency
        translations of our operations based in Mexico and the United Kingdom as
        their respective currencies declined in value relative to the U.S.
        dollar during the quarter.

                                   Page 2 of 7


     -  "Capital expenditures during 2008 totaled $22.3 million and capital
        expenditures in 2009 are expected to be between $20 million and $25
        million.

     -  "Late in the year, our European copper tube operation was damaged by
        fire.  Production was curtailed for approximately four weeks to make the
        necessary temporary repairs.  Certain production equipment and portions
        of the building structures were extensively damaged requiring further
        assessment which is underway; rehabilitation alternatives are also being
        evaluated.  The total value of the loss, including business
        interruption, cannot be determined at this time but is expected to be
        covered by our property insurance."

Business Outlook for 2009

     Regarding the outlook for 2009, Mr. Karp said, "Mueller's operating results
for 2008 were gratifying, considering the state of the U.S. economy and the
decline in global markets.  We are now in the second year of a recession which
appears likely to be the longest downturn since World War II.

     "Mueller's strategy for 2009 is to promptly readjust our operations to the
on-going flow of business.  We see many opportunities to improve our operations
and reduce costs.  It is our objective to emerge from the current economic
malaise a stronger, more efficient and lower-cost competitor.

     "Our strong balance sheet will enable us to fund our capital improvement
programs from internal sources.  We are also investigating acquisition
opportunities which are directly related to our core business capabilities. We
have always been cautious in evaluating acquisition candidates, and we will
continue to do so."
