                   MUELLER INDUSTRIES, INC. REPORTS 45 PERCENT
                     INCREASE IN FIRST QUARTER 2008 EARNINGS


      Harvey L. Karp, Chairman of Mueller Industries, Inc. (NYSE: MLI),
announced today that Mueller's net income increased 45 percent in the first
quarter of 2008 to $27.4 million, or 73 cents per diluted share. This compares
with $18.9 million, or 51 cents per diluted share, for the same period of 2007.
First quarter net sales for 2008 were $704.1 million compared with $609.8
million in 2007. The increase in net sales was primarily attributable to
acquired businesses. The change in net sales was also affected by the increased
cost of copper, the Company's principal raw material, which was largely passed
through to customers, offset by lower unit volume.

Financial and Operating Highlights

      Regarding the first quarter of 2008, Mr. Karp said:

      o     "Our Plumbing & Refrigeration segment posted operating earnings of
            $25.1 million on net sales of $383.9 million which compares with
            prior year earnings of $26.9 million on net sales of $370.0 million.
            Operating results were affected by lower spreads and unit shipments
            in copper tube and DWV plastic fittings. Other key product lines
            performed well.

      o     "Our OEM segment posted operating earnings of $25.6 million during
            the first quarter of 2008 on net sales of $326.2 million, which
            compares with operating earnings of $5.5 million on net sales of
            $243.7 million for the same period in 2007. The acquisition of
            Extruded Metals, a brass rod mill, at the end of February 2007 was
            an important contributor to the improvement in our operating income
            during the quarter. We believe there are additional opportunities to
            rationalize production as we integrate our brass rod mill
            operations.

                                   Page 1 of 6


      o     "Other income includes a gain of $2.4 million related to the early
            retirement of debt.

      o     "During the first quarter of 2008, capital expenditures totaled $8.6
            million. We expect to invest between $30 and $40 million for capital
            expenditures during 2008.

      o     "The COMEX average price of copper was $3.53 per pound in the first
            quarter of 2008, which compares with $2.70 in the first quarter of
            2007.

      o     "Our current ratio remains solid at 2.8 to 1. We ended the quarter
            with $274.3 million in cash and $634.9 million in working capital.

      o     "Our return on average equity was 18.5 percent for the four quarters
            ended March, 2008.

      o     "As of year end, our financial leverage was modest with a debt to
            total capitalization ratio of 32.3 percent.

      o     "Total stockholders' equity was $737.8 million which equates to a
            book value per share of $19.89 of which $7.39 per share is in cash."


Business Outlook for 2008

      Regarding the outlook for 2008, Mr. Karp said, "The housing construction
market continues to contract. Housing starts have already declined almost 60
percent over the past 2 1/2 years. However, we believe the market is close to a
bottom, and that it will soon commence a gradual, but perhaps fitful,
improvement. Mortgage rates remain at historically low levels and will provide
an incentive for buyers to return to the housing market.

      "On the other hand, the private non-residential construction market, an
important market for Mueller, continues to show strength. So far this year it
has grown at an annualized rate of 13 percent.

      "Economists are divided over whether our nation has entered into a
recession. If, in fact, we are in a recession, our goal is to emerge from the
downturn, a stronger and more formidable competitor."

      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;
refrigeration valves and fittings; and fabricated tubular products. Mueller's
operations are located throughout the United States and in Canada, Mexico, Great
Britain, and China. Mueller's business is importantly linked to: (1) the
construction of new homes; (2) the improvement and reconditioning of existing
homes and structures; and (3) the commercial construction market which includes
office buildings, factories, hotels, hospitals, etc.
