                          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 September
27, 2003 was $10.0 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
entity and in determining the primary beneficiary.  The interpretation

                                      -11-

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 adoption of FIN 46 will not
have an effect on the financial position or results of operations of the
Company.

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.

Note 7 - Income Tax Benefit (Expense)

     During the third quarter of 2003, the Company recognized a deferred
income tax benefit, upon the closure of the open tax year, by reducing a
valuation allowance of $9.3 million related to an operating loss resulting
from the 1999 sale of a subsidiary.  Realization of the tax benefit occurred
during the year of sale.

     The sale of the Company's Utah Railway Company subsidiary during the
third quarter of 2002 enabled the Company to utilize previously unrecognized

                                      -14-

capital loss carryforwards.  In accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes", the recognition
of this capital loss carryforward benefit of $12.7 million was classified as
a reduction to current income taxes on continuing operations, resulting in a
net current income tax benefit for the third quarter of 2002.

Note 8 - Discontinued Operations

     During the third quarter of 2002, the Company completed the sale of its
wholly owned subsidiary, Utah Railway Company.  Proceeds from the sale were
approximately $55.4 million.  The Company recognized a gain of $21.1 million
(net of income taxes of $11.6 million) from the sale.  Also during 2002 the
Company initiated the disposal of its subsidiary, Mueller Europe S.A.  The
Company expects no further obligations or contingencies from these
discontinued operations and, therefore, during the third quarter of 2003 it
recognized a $1.7 million after tax gain to reflect adjustments to the
previous estimates on disposition.


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

General Overview

     The Company 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.  The Company'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.

                                      -15-

Results of Operations

     Income from continuing operations was $19.7 million, or 53 cents per
diluted share, for the third quarter of 2003, compared with income from
continuing operations of $25.8 million, or 70 cents per diluted share, for
the same period of 2002.  Year-to-date, income from continuing operations was
$33.2 million, or 89 cents per diluted share, compared with income from
continuing operations of $62.4 million, or $1.68 per diluted share, for 2002.

     During the third quarter of 2003, the Company's net sales were $251.1
million, which compares with net sales of $227.3 million over the same period
of 2002, an increase of 10.5 percent.  Net sales were $731.3 million in the
first nine months of 2003 compared with $736.9 million in the same period of
2002.  The average price of copper was approximately 7 percent higher in the
nine-month period of 2003 compared with the same period of 2002.  During the
third quarter of 2003, the Company's manufacturing businesses shipped 175
million pounds of product compared to 164 million pounds in the same quarter
of 2002.  The Company shipped 532 million pounds of product in the nine
months ended September 27, 2003 compared with 517 million in the same period
of 2002.

     Cost of goods sold increased from $176.3 million in the third quarter of
2002 to $202.0 million in the same period of 2003.  This increase was
attributable to higher volumes, higher material costs, and increases in
certain manufacturing costs including health care benefit costs and packaging
costs.  Selling, general, and administrative expense increased from $21.3
million in the third quarter of 2002 to $24.3 million in the third quarter of
2003.  This increase relates primarily to (i) components of the Company's
pension cost, including interest cost, expected return on plan assets, and
amortization of plan gains and losses, (ii) increased provision for bad
debts, and (iii) increased professional fees.  Depreciation and amortization
expense increased to $9.8 million and $29.2 million for the third quarter and
nine months ended September 27, 2003, respectively, compared with $9.3
million in the third quarter and $27.5 million in the first nine months of
2002.  The increase was due to recent capital expenditures and businesses
acquired during the second half of 2002.

     Third quarter operating income decreased from the comparable period in
the prior year primarily due to increased operating costs identified above.
Year-to-date operating income decreased from the comparable period in the
prior year primarily due to reduced spreads in certain product lines,
primarily domestic copper tube, and increased operating costs identified
above.  The third quarter 2003 operating income of $15.0 million represents
an increase of $3.6 million over the preceding second quarter 2003 operating
income.  This improvement is primarily due to improved spreads in certain
product lines, primarily domestic copper tube.  The Company's European
operations continued to show a modest profit during the third quarter of
2003.

     Interest expense for the third quarter of 2003 totaled $0.3 million,
even with the same period of 2002.  For the first nine months of 2003,
interest expense was $0.9 million compared with $1.2 million for the same
period of 2002.  No interest was capitalized in the nine months of 2003 or
the comparable period of 2002.  Total interest in the third quarter and first
nine months of 2003 decreased due to debt reductions.



                                      -16-

     During the third quarter of 2003, the Company recognized a deferred
income tax benefit, upon the closure of the open tax year, by reducing a
valuation allowance of $9.3 million related to an operating loss resulting
from the 1999 sale of a subsidiary.  Realization of the tax benefit occurred
during the year of sale.  Without this deferred income tax benefit, the
Company would have recognized income tax expense of approximately $4.8
million, or approximately 32 percent of pretax income from continuing
operations during the third quarter of 2003.  Without this deferred income
tax benefit, the Company's income from continuing operations would have been
approximately $10.4 million, or 28 cents per diluted share for the third
quarter and would have been approximately $23.9 million, or 65 cents per
diluted share, for the first three quarters of 2003.

     The sale of the Company's Utah Railway Company subsidiary during the
third quarter of 2002 enabled the Company to utilize previously unrecognized
capital loss carryforwards.  In accordance with Statement of Financial
Accounting Standards No. 109, "Accounting for Income Taxes", the recognition
of this capital loss carryforward benefit of $12.7 million was classified as
a reduction to current income taxes on continuing operations, resulting in a
net current income tax benefit for the third quarter of 2002.  Without the
benefit of the capital loss carryforwards, the Company would have recognized
income tax expense of approximately $7.6 million, or approximately 37 percent
of pretax income from continuing operations.  Without the benefit of the
capital loss carryforwards, the Company's income from continuing operations
would have been approximately $13.2 million, or 36 cents per diluted share
for the third quarter and would have been approximately $49.7 million, or
$1.34 per diluted share, for the first three quarters of 2002.

     The Company recognized proceeds from the sale of Utah Railway Company in
the third quarter of 2002 of approximately $55.4 million.  The Company
recognized a gain of $21.1 million (net of income taxes of $11.6 million)
from the sale.  Also during 2002 the Company initiated the disposal of its
subsidiary, Mueller Europe S.A.  The Company expects no further obligations
or contingencies from these discontinued operations and, therefore, during
the third quarter of 2003 it recognized a $1.7 million after tax gain to
reflect adjustments to the previous estimates on disposition.


Liquidity and Capital Resources

     Cash provided by operating activities in the first nine months of 2003
totaled $34.1 million, which was primarily attributable to net income from
continuing operations, depreciation and amortization, 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 nine months of 2003, the Company used $33.1 million for
investing activities, consisting primarily of $10.8 million for the purchase
of a minority interest in Conbraco Industries, Inc. common stock, and $24.1
million for capital expenditures.  The Company also used $2.7 million for
financing activities during the nine-month period, consisting primarily of
repayments of long-term debt.  Existing cash balances and escrowed IRB
proceeds were used to fund the Company's investing and financing activities.



                                      -17-

     The Company's Board of Directors has authorized the repurchase until
October 2004 of up to ten million shares of the Company's common stock
through open market transactions or through privately negotiated
transactions.  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 September 27, 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 September 27, 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 September 27, 2003.  The Company expects to enter into a new
credit agreement with similar terms prior to the maturity date of the
existing Credit Facility.

     The Company expects to invest between $30 and $35 million for capital
projects during 2003.  Management believes that cash provided by operations
and currently available cash of $219.3 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 September 27, 2003.


Item 3.  Quantitative and Qualitative Disclosures About Market Risk

     During the third quarter, the Company entered into forward contracts to

Item 4.  Controls and Procedures


     The Company maintains disclosure controls and procedures designed to
ensure information required to be disclosed in Company reports filed under
the Securities Exchange Act of 1934, as amended, (the Exchange Act) is
recorded, processed, summarized, and reported within the time periods
specified in the Securities and Exchange Commission's rules and forms.
Disclosure controls and procedures are designed to provide reasonable

                                      -18-

assurance that information required to be disclosed in Company reports filed
under the Exchange Act is accumulated and communicated to management,
including the Company's Chief Executive Officer and Chief Financial Officer,
as appropriate, to allow timely decisions regarding required disclosure.

     The Company's management, under the supervision and with the
participation of the Company's Chief Executive Officer and Chief Financial
Officer, has evaluated the effectiveness of the Company's disclosure controls
and procedures as of the end of the period covered by this report.  Based
upon that evaluation, the Company's Chief Executive Officer and Chief
Financial Officer concluded that the disclosure controls and procedures are
effective.

     There were no changes in the Company's internal control over financial
reporting during the Company's fiscal quarter ending September 27, 2003, that
have materially affected, or are reasonably likely to materially affect the
Company's internal control over financial reporting.
