                          MUELLER INDUSTRIES, INC.
                 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                                 (Unaudited)

General

     Certain information and footnote disclosures normally included in
financial statements prepared in accordance with accounting principles
generally accepted in the United States have been condensed or omitted.
Results of operations for the interim periods presented are not necessarily
indicative of results which may be expected for any other interim period or
for the year as a whole.  This Quarterly Report on Form 10-Q should be read
in conjunction with the Company's Annual Report on Form 10-K, including the
annual financial statements incorporated therein by reference.

     The accompanying unaudited interim financial statements include all
adjustments which are, in the opinion of management, necessary to a fair
statement of the results for the interim periods presented.

Note 1 - Earnings Per Common Share

     Basic per share amounts have been computed based on the average number
of common shares outstanding.  Diluted per share amounts reflect the increase
in average common shares outstanding that would result from the assumed
exercise of outstanding stock options, computed using the treasury stock
method.

Note 2 - Commitments and Contingencies

     The Company is subject to normal environmental standards imposed by
federal, state, local, and foreign environmental laws and regulations.  Based
upon information currently available, management believes that the outcome of
pending environmental matters will not materially affect the overall
financial position and results of operations of the Company.

     In addition, the Company is involved in certain litigation as either
plaintiff or defendant as a result of claims that have arisen in the ordinary
course of business which management believes will not have a material effect
on the Company's financial condition or results of operations.

     The Company has guarantees which are letters of credit issued by the
Company generally to guarantee the payment of insurance deductibles, retiree
health benefits, and certain operating costs of a foreign subsidiary.  The
terms of the Company's guarantees are generally one year but are renewable
annually as required.  The maximum potential amount of future payments the
Company could have been required to make under its guarantees at June 28,
2003 was $14.1 million.

Note 3 - Recently Issued Accounting Standards

     In January 2003, the Financial Accounting Standards Board issued
Interpretation No. 46, "Consolidation of Variable Interest Entities" (FIN 46).
FIN 46 provides accounting requirements for business enterprises to
consolidate related entities in which they are determined to be the primary
beneficiary as a result of their variable economic interests.  The
interpretation provides guidance in judging multiple economic interests in an


                                      -11-

entity and in determining the primary beneficiary.  The interpretation
outlines disclosure requirements for variable interest entities (VIEs) in
existence prior to January 31, 2003, and provides consolidation requirements
for VIEs created after January 31, 2003.  The Company is currently evaluating
the impact of FIN 46 and does not expect the adoption of FIN 46 to have a
material effect on its earnings or its financial position.

Note 6 - Stock-Based Compensation

     The Company accounts for its stock-based compensation plans using the
intrinsic value method prescribed in Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees", and related Interpretations.
No stock-based employee compensation expense is reflected in net income
because the exercise price of the Company's incentive employee stock options
equals the market price of the underlying stock on the date of grant.  The
following table illustrates the effect on net income and earnings per share
if the Company had applied the fair value recognition provisions of Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS No. 123), to stock-based employee compensation.

Item 2.  Management's Discussion and Analysis of Financial Condition and
Results of Operations


General Overview

     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, and Great Britain.

     The Company's businesses are managed and organized into two segments:
Standard Products Division (SPD) and Industrial Products Division (IPD).  SPD
manufactures and sells copper tube, copper and plastic fittings, and valves.
Outside of the United States, SPD manufactures and sells copper tube in
Europe.  SPD sells these products to wholesalers in the HVAC (heating,
ventilation, and air-conditioning), plumbing, and refrigeration markets, to
distributors to the manufactured housing and recreational vehicle industries,
and to building material retailers.  IPD manufactures and sells brass and
copper alloy rod, bar, and shapes; aluminum and brass forgings; aluminum and
copper impact extrusions; refrigeration valves and fittings; fabricated
tubular products; and gas valves and assemblies.  IPD sells its products
primarily to original equipment manufacturers (OEMs), many of which are in
the HVAC, plumbing, and refrigeration markets.

     New housing starts and commercial construction are important
determinants of the Company's sales to the HVAC, refrigeration and plumbing
markets because the principal end use of a significant portion of the
Company's products is in the construction of single and multi-family housing
and commercial buildings.  Profitability of certain of the Company's product
lines depends upon the "spreads" between the cost of raw material and the
selling prices of its completed products.  The open market prices for copper
cathode and scrap, for example, influence the selling price of copper tubing,
a principal product manufactured by the Company.  The Company attempts to
minimize the effects of fluctuations in material costs by passing through
these costs to its customers.  Spreads fluctuate based upon market
conditions.


Results of Operations

     Net income was $9.0 million, or 24 cents per diluted share, for the
second quarter of 2003, compared with net income of $18.5 million, or 50
cents per diluted share, for the same period of 2002.  Year-to-date, net
income was $12.9 million, or 35 cents per diluted share, compared with net
income of $36.4 million, or 98 cents per diluted share, for 2002.

     During the second quarter of 2003, the Company's net sales were $248.2
million, which compares with net sales of $260.5 million over the same period
of 2002, or a five percent decrease.  Net sales were $480.2 million in the

first half of 2003 compared with $509.6 million in the same period of 2002.
The average price of copper was approximately three percent higher in the
first half of 2003 compared with the same period of 2002.  During the second


                                      -15-

quarter of 2003, the Company's manufacturing businesses shipped 175 million
pounds of product compared to 187 million pounds in the same quarter of 2002.
The Company shipped 342 million pounds of product in the first half of 2003
compared with 368 million in the same period of 2002.  This decline in volume
as well as decreased selling prices in certain product lines, primarily
copper tube, resulted in the reduction in net sales.

     Cost of goods sold increased from $201.4 million in the second quarter
of 2002 to $203.5 million in the same period of 2003.  This increase was
attributable to higher material costs and increases in certain manufacturing
costs including health care benefit costs and packaging costs.  Selling,
general, and administrative expense increased from $22.4 million in the
second quarter of 2002 to $23.6 million in the second quarter of 2003.  This
increase relates primarily to components of the Company's pension cost,
including interest cost, expected return on plan assets, and amortization of
plan gains and losses, and increased professional fees.   Depreciation and
amortization expense increased to $9.7 million and $19.5 million for the
second quarter and first half of 2003, respectively, compared with $9.2
million in the second quarter and $18.2 million in the first half of 2002.
The increase was due to recent capital expenditures and businesses acquired
during the second half of 2002.

     Second quarter and first half operating income decreased from the
comparable periods in the prior year primarily due to reduced spreads in
certain product lines, primarily domestic and European copper tube.  The
Company's European operations showed a modest profit for the second quarter
of 2003.

     Interest expense for the second quarter of 2003 totaled $0.3 million,
even with the same period of 2002.  For the first six months of 2003,
interest expense was $0.6 million compared with $0.8 million for the same
period of 2002.  No interest was capitalized in the first half of 2003 or the
first half of 2002.  Total interest in the second quarter and first half of
2003 decreased due to debt reductions.

     The Company's effective income tax rate for the first half of 2003 was
33.5 percent compared with 34.2 percent for the first half of 2002.


Liquidity and Capital Resources

     Cash provided by operating activities in the first half of 2003 totaled
$14.1 million, which was primarily attributable to net income from continuing
operations, depreciation and amortization, deferred income taxes, decreased
inventories, and increased current liabilities partially offset by increased
receivables.  Fluctuations in the cost of copper and other raw materials
affect the Company's liquidity.  Changes in material costs directly impact
components of working capital, primarily inventories and accounts receivable.

     During the first six months of 2003, the Company used $26.1 million for

investing activities, consisting primarily of $10.8 million for the purchase
of Conbraco Industries, Inc common stock, plus $16.0 million for capital
expenditures.  The Company also used $1.8 million for financing activities
during the six-month period, consisting primarily of repayments of long-term
debt.  Existing cash balances and escrowed IRB proceeds were used to fund the
first half investing and financing activities.

                                      -16-

     During 1999, the Company's Board of Directors authorized the repurchase
of up to four million shares of the Company's common stock through open
market transactions or through privately negotiated transactions.  This
authorization was expanded up to a total of ten million shares, and was
extended through October 2003.  The Company has no obligation to purchase any
shares and may cancel, suspend, or extend the time period for the purchase of
shares at any time.  Any purchases will be funded primarily through existing
cash and cash from operations.  The Company may hold any shares purchased in
treasury or use a portion of the repurchased shares for employee benefit
plans, as well as for other corporate purposes.  Through June 28, 2003, the
Company had repurchased approximately 2.4 million shares under this
authorization.

     The Company has an unsecured $200 million revolving credit facility (the
Credit Facility), which matures in November 2003.  At June 28, 2003, there
were no outstanding borrowings under the Credit Facility.  Borrowings under
the Credit Facility bear interest, at the Company's option, at (i) LIBOR plus
a variable premium or (ii) the greater of Prime, or the Federal Funds rate
plus .50 percent.  LIBOR advances may be based upon the one, two, three, or
six-month LIBOR.  The variable premium over LIBOR is based on certain
financial ratios, and can range from 25 to 40 basis points.  Additionally, a
facility fee is payable quarterly on the total commitment and varies from
12.5 to 22.5 basis points based upon the Company's capitalization ratios.
When funded debt is 50 percent or more of the commitment, a utilization fee
is payable quarterly on the average loan balance outstanding and varies from
0 to 20 basis points based upon the capitalization ratio.  Availability of
funds under the Credit Facility is reduced by the amount of certain
outstanding letters of credit, which totaled approximately $6.9 million at
June 28, 2003.

     Under the Credit Facility the Company is required, among other things,
to maintain certain minimum levels of net worth and meet certain minimum
financial ratios.  At June 28, 2003 the Company was in compliance with all
debt covenants.

     The Company expects to invest between $35 and $40 million for capital
projects during 2003.  Management believes that cash provided by operations
and currently available cash of $207.4 million will be adequate to meet the
Company's normal future capital expenditure and operational needs.  The
Company's current ratio was 5 to 1 at June 28, 2003.


Item 3.  Quantitative and Qualitative Disclosures About Market Risk


     Quantitative and qualitative disclosures about market risk are
incorporated herein by reference to Part II, Item 7A, of the Company's Report

Item 4.  Controls and Procedures


     An evaluation was performed, under the supervision and with the
participation of the Company's management, including the Chief Executive
Officer (CEO) and Chief Financial Officer (CFO), of the effectiveness of the
design and operation of the Company's disclosure controls and procedures,
within 90 days before the filing date of this quarterly report.  Based on
that evaluation, the Company's management, including the CEO and CFO,
concluded that the Company's disclosure controls and procedures were
effective in timely alerting them to material information relating to the
Company (including its consolidated subsidiaries) required to be included in
the Company's periodic SEC filings.  There have been no significant changes
in the Company's internal controls or in other factors that could
significantly affect internal controls subsequent to their evaluation.
