                          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.

     Certain amounts in the Consolidated Financial Statements have been
reclassified to conform to the 2003 presentation.


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 arise 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 and
retiree health benefits.  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 be required to make under its
guarantees at March 29, 2003 is $6.6 million.

Note 5 - 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

                                     -11-


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.  SPD and IPD account 100
percent of consolidated net sales and more than 77 percent of consolidated
total assets.

     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 $3.9 million, or 11 cents per diluted share, for the
first quarter of 2003, which compares with net income of $17.9 million, or 48
cents per diluted share, for the same period of 2002.

     During the first quarter of 2003, the Company's net sales were $232.0
million compared with net sales of $249.1 million over the same period of
2002.  Pounds shipped totaled 166.6 million in the current period compared
with shipments of 181.5 million in the first quarter of 2002.  This decline
in volume as well as decreased selling prices in certain product lines
resulted in the reduction in net sales.

     Cost of goods sold increased from $191.8 million in the first quarter of
2002 to $191.9 million in the same period of 2003.  This increase is
attributable to increases in raw material costs, primarily copper, partially
offset by reductions in conversion costs.  The COMEX average copper price in
the first quarter of 2003 was approximately six percent greater than in the
same period of 2002.

     Depreciation and amortization expense increased to $9.7 million for the
first quarter of 2003 compared with $9.1 million during the first quarter of
2002.  The increase was due primarily to businesses acquired in the second
half of 2002.  Selling, general, and administrative expense was $23.3 million
for the first quarter of 2003 compared with $22.0 million for the same period
of 2002.  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.

     Interest expense in the first quarter of 2003 totaled $0.3 million,
which was $0.2 million less than the first quarter of 2002.  This decrease
was due to lower funded balances in 2003.  No interest was capitalized during
the first quarter of 2003 or during the first quarter of 2002.
                                     -12-


     The Company's effective income tax rate for the first quarter of 2003
was 37.3 percent compared with 34.2 percent for the first quarter of last
year.

     During 2002, the Company sold its wholly owned subsidiary, Utah Railway
Company, and initiated steps to sell or liquidate its French manufacturing
operations, Mueller Europe S.A.  The operations and cash flows of these two
businesses have been eliminated from the ongoing operations of the Company,
and are reported as discontinued operations.

     On March 3, 2003, Mueller Europe S.A. filed a petition for liquidation
with the Commercial Court of Provins Province, France and, on March 4, the
Court declared the entity to be in liquidation. The disposition of remaining
assets and obligations of Mueller Europe S.A. is under the jurisdiction of
the Court. In the first quarter of 2003 the Company recognized operating
losses from discontinued operations incurred by Mueller Europe S.A. for the
period the business operated.


Liquidity and Capital Resources

     Cash used in operating activities in the first quarter of 2003 totaled
$6.0 million, which is primarily attributable to increased receivables,
increased inventories, and decreased liabilities, partially offset by net
income from continuing operations and depreciation and amortization.
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 quarter of 2003, the Company used $16.9 million for
investing activities, consisting primarily of $10.8 million for the purchase
of Conbraco Industries, Inc common stock, plus $6.6 million for capital
expenditures.  The Company also used $1.1 million for financing activities
during the quarter, consisting of repayments of long-term debt.  Existing
cash balances and escrowed IRB proceeds were used to fund the first quarter
investing and financing activities.

     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 to repurchase up to a total of ten million shares,
and has been 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.  The purchases will be funded primarily
through existing cash and cash from operations.  The Company may hold such
shares in treasury or use a portion of the repurchased shares for employee
benefit plans, as well as for other corporate purposes.  Through March 29,
2003, the Company has 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 March 29, 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 larger of Prime, or the Federal Funds rate
plus .50 percent.  LIBOR advances may be based upon the one, two, three, or

                                     -13-


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 $6.6 million at
March 29, 2003.

     Under the above Agreement the Company is required, among other things,
to maintain certain minimum levels of net worth and meet certain minimum
financial ratios.  The Company is in compliance with all debt covenants.

     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 $194.9 million will be adequate to meet the
Company's normal future capital expenditure and operational needs.  The
Company's current ratio is 5.1 to 1 at March 29, 2003.


Item 3.  Quantitative and Qualitative Disclosure of Market Risk

     Quantitative and qualitative disclosures about market risk are
incorporated herein by reference to Part II, Item 7A, of the Company's Report
on Form 10-K for the year ended December 28, 2002.


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.


Part II.  Other Information

Item 5.  Other Information

     The Company is aware of investigations of competition in markets in
which it participates, or has participated in the past, in Europe, Canada,
and the United States.  No charges or allegations have been filed against the
Company, which is cooperating with the investigations.  The Company does not
anticipate any material adverse effect on its business or financial condition
as a result of the investigations.
