                        MUELLER INDUSTRIES, INC. REPORTS
                     FOURTH QUARTER AND FISCAL 2007 EARNINGS

         Harvey L. Karp, Chairman of Mueller Industries, Inc. (NYSE: MLI),
announced today that Mueller's net income for the fiscal year ended December 29,
2007 was $115.5 million, or $3.10 per diluted share, which compares with $148.9
million, or $4.00 per diluted share, for 2006. Net sales for 2007 were $2.70
billion compared with $2.51 billion in 2006.

         For the fourth quarter of 2007, the Company's net income was $28.8
million, or 78 cents per diluted share, on net sales of $621.7 million. This
compares with net income of $5.2 million, or 14 cents per diluted share, on net
sales of $544.2 million for the fourth quarter of 2006.


Financial and Operating Highlights

         Mr. Karp said:

         o  "The increase in net sales is primarily due to the acquisition of
            Extruded Metals, Inc. as well as the higher average cost of copper,
            the Company's principal raw material, which is generally passed
            through to customers by changes in selling prices. The COMEX average
            price of copper was $3.25 per pound in the fourth quarter of 2007.

         o  "During the fourth quarter of 2007, the Company recognized LIFO
            income of $10.0 million (or 17 cents per diluted share after tax)
            resulting from a decrease in inventory quantities accounted for
            under the LIFO method. The fourth quarter of 2006 included a pre-tax
            charge of approximately $14.2 million (or 26 cents per diluted share
            after tax) due to a write-down of inventories to the lower of cost
            or market.

         o  "Our return on average equity was 17.8 percent for 2007.

         o  "Our current ratio remains strong at 2.8 to 1 and our working
            capital is $605.3 million, of which over $300 million is cash on
            hand.

                                   Page 1 of 6


         o  "Cash provided by operating activities was $185.8 million in 2007
            compared with $64.5 million during 2006.

         o  "As of year end, our financial leverage was modest with a debt to
            total capitalization ratio of 33.3 percent.

         o  "Total stockholders' equity was $710.5 million which equates to a
            book value per share of $19.16 of which $8.32 per share is in cash.

         o  "For the full year, our Plumbing & Refrigeration segment posted
            operating earnings of $178.4 million on net sales of $1.57 billion
            which compares with operating earnings of $197.4 million on net
            sales of $1.72 billion in 2006. Operating earnings includes LIFO
            income of $10.0 million in 2007. Also, in the fourth quarter of
            2007, we wrote down the goodwill carrying value of our Mexican
            operations by $2.8 million due to an impairment charge.

         o  "Our OEM segment posted operating earnings of $38.2 million during
            the year on net sales of $1.14 billion, which compares with
            operating earnings of $44.8 million on net sales of $835.3 million
            for 2006.

         o  "Capital expenditures during 2007 totaled $29.9 million; cash flow
            to fund capital expenditures in 2008 are expected to be less than
            depreciation.

         o  "After year end, we acquired approximately $25.5 million of our
            outstanding 6% Subordinated Debentures at approximately 90 percent
            of face value. Accordingly, these were reclassified to the current
            portion of long-term debt on our balance sheet."


Business Outlook for 2008

         Regarding the outlook for 2008, Mr. Karp said, "Despite the challenges
presented by the decline in the housing market, and the volatility in the prices
of copper and energy, Mueller had its two best years ever in 2006 and 2007.

         "The year 2008 will also be challenging as the national economy is
slowing down and the housing market continues to contract. However, the U.S.
economy has proven itself to be remarkably resilient, and we believe that later
this year the housing market will bottom out and then gradually start to
improve.

                                   Page 2 of 6


         "Also, we anticipate that our non-residential businesses, which
constitute a significant portion of our total, will have another good year in
2008.

         "Mueller is well positioned to take advantage of opportunities in our
marketplace. On average, we have made one or more acquisitions per year over the
past decade. We will continue our quest to acquire sound companies which are
compatible with our core businesses."
