NOTE 1 -- INTERIM FINANCIAL STATEMENTS
 
     The accompanying unaudited consolidated condensed financial statements
include the accounts of Metal Management, Inc. and its subsidiaries (herein
referred to as "MTLM" or the "Company") and have been prepared by the Company
pursuant to the rules and regulations of the Securities and Exchange Commission.
All significant intercompany accounts, transactions and profits have been
eliminated. Certain information related to the Company's organization,
significant accounting policies and footnote disclosures normally included in
financial statements prepared in accordance with generally accepted accounting
principles have been condensed or omitted. These unaudited consolidated
condensed financial statements reflect, in the opinion of management, all
material adjustments (which include only normal recurring adjustments) necessary
to fairly state the financial position and the results of operations for the
periods presented and the disclosures herein are adequate to make the
information presented not misleading. Operating results for interim periods are
not necessarily indicative of the results that can be expected for a full year.
These interim financial statements should be read in conjunction with the
Company's audited consolidated financial statements and notes thereto included
in the Company's Annual Report on Form 10-K for the year ended March 31, 1998
and in the Company's Current Report on Form 8-K dated July 1, 1998.
 
     In order to maintain consistency and comparability between periods
presented, certain amounts have been reclassified from the previously reported
financial statements in order to conform with the financial statement
presentation of the current period.
 
NOTE 2 -- MERGERS AND ACQUISITIONS
 
  Mergers accounted as Pooling-of-Interests
 
     On May 28, 1998, the Company merged with R&P Holdings, Inc. ("Bluestone")
through a tax-free stock-for-stock exchange. The Company issued 1,034,826 shares
of common stock, par value $.01 per share ("Common Stock") in exchange for all
the outstanding common stock of Bluestone. The merger is accounted for as a
pooling-of-interests under Accounting Principles Board (APB) No. 16, "Business
Combinations." All financial data of the Company, including the Company's
previously issued financial statements presented in this Form 10-Q, have been
restated to include the historical financial information of Bluestone in
accordance with generally accepted accounting principles and pursuant to
Regulation S-X. Certain reclassifications were made to Bluestone financial
statements to conform to the Company's presentation.

</TABLE>
 
     The above transactions have been accounted for by the purchase method of
accounting and are included in the Company's results of operations from the
effective date of each respective acquisition. The purchase price was allocated
based on estimates of the fair value of assets acquired and liabilities assumed.
These estimates are revised during the allocation period as necessary when
information regarding contingencies becomes available to define and quantify
assets acquired and liabilities assumed. The allocation period varies by
acquisition but does not usually exceed one year. It is not expected that the
finalization of purchase accounting will have any significant effect on the
financial position and results of operations of the Company.
 
  Acquisitions completed subsequent to June 30, 1998
 
     - In July 1998, the Company acquired the common stock of Naporano Iron &

NOTE 4 -- DEBT
 
  Senior Credit Facility
 
     On March 31, 1998, the Company and its subsidiaries entered into a three
year credit facility (the "Senior Credit Facility") with BT Commercial
Corporation, as agent for the lenders (the "Agent") and certain commercial
lending institutions. The Senior Credit Facility, as amended, provides for a
revolving credit and letter of credit facility of $250 million, subject to
borrowing base limitations (described below).

                                  (UNAUDITED)
 
The Senior Credit Facility bears interest at a floating rate per annum equal to
(at the Company's option): (i) 1.75% over LIBOR or (ii) 0.5% over the agent
lender's prime rate. The Company pays an unused line fee of .375% and is subject
to debt covenants including an interest coverage ratio and limitations with
respect to capital expenditures. The Senior Credit Facility is available for
working capital and general corporate purposes, including acquisitions. The
obligations of the Company and its subsidiaries under the Senior Credit Facility
are secured by a security interest in substantially all of the assets and
properties of the Company and its subsidiaries, including pledges of capital
stock of the Company's subsidiaries. Availability of loans and letters of credit
under the Senior Credit Facility is generally limited to a borrowing base of 85%
of eligible accounts receivable, 70% of eligible inventory and a fixed asset
sublimit ($55.6 million as of June 30, 1998) that amortizes on a quarterly
basis. At June 30, 1998, the Company had borrowings of approximately $0.1
million outstanding under the Senior Credit Facility.
 
     During the quarter, the Company borrowed under the Senior Credit Facility
to refinance existing secured debt, buyout certain operating leases and pay
prepayment penalties associated with the early retirement of debt. In connection
with the refinancing of debt, the Company recognized an extraordinary charge of
approximately $862,000 during the three months ended June 30, 1998 consisting of
the following (in thousands):

  Senior Subordinated Notes
 
     On May 13, 1998, the Company issued $180 million of 10.0% Senior
Subordinated Notes due on May 15, 2008 (the "Notes") in a private placement (the
"Subordinated Debt Placement"). Interest on the Notes is payable semi-annually.
The Company received net proceeds of $174.6 million in the Subordinated Debt
Placement. The Notes are general unsecured obligations of the Company and are
subordinated in right to payment to all senior debt of the Company, including
the indebtedness of the Company under the Senior Credit Facility. The Company's
payment obligations are jointly and severally guaranteed by the Company's
current and certain future subsidiaries. The proceeds of the Notes were used to
repay approximately $119.0 million outstanding under the Company's Senior Credit
Facility and approximately $19.1 million of notes payable to related parties.
The balance of the proceeds was invested in marketable securities held for
working capital and general corporate purposes, including acquisitions.
 
     Except as described below, the Notes are not redeemable at the Company's
option prior to May 15, 2003. After May 15, 2003, the Notes are redeemable by
the Company at the redemption prices (expressed as a percentage of the principal
amount and rounded to the nearest whole percentage) plus accrued and unpaid
interest, if redeemed during the twelve month period beginning on May 15 of each
of the years indicated below:

     Also, prior to March 15, 2001, the Company may redeem up to 35% of the
aggregate principal amount of the Notes at a redemption price of 110% of the
principal amount of the Notes, plus accrued and unpaid interest from the
proceeds of one or more sales of Common Stock. The Notes are also redeemable at
the option of the holder thereof at a repurchase price of 101% of the principal
amount thereof, plus accrued and unpaid interest in the event of certain change
of control events with respect to the Company.
 
     The Indenture governing the Notes (the "Indenture") contains certain
covenants that limit, among other things, the ability of the Company and its
subsidiaries to (i) incur additional indebtedness (including by way of
guarantee), subject to certain exceptions, unless the Company meets a fixed
charge ratio of 2 to 1 or certain other conditions apply; (ii) issue certain
types of securities containing mandatory redemption rights or which otherwise
are redeemable at the option of the holder thereof prior to the maturity of the
Notes; (iii) pay dividends or distributions, or make certain types of
investments or other payments, unless the Company meets a fixed charge coverage
ratio of 2 to 1 and the amount of the dividend or distribution, investment or
other payment (together with all such other dividend, distributions, investments
or other payments made through the date thereof) is less than 50% of the
consolidated net income of the Company from the beginning of the fiscal quarter
immediately following the date of the Indenture through the most recently ended
fiscal quarter plus the aggregate amount of net equity proceeds received by the
Company in such period; (iv) enter into certain transactions with affiliates;
(v) dispose of certain assets; (vi) incur liens securing pari passu or
subordinated indebtedness of the Company; or (vii) engage in certain mergers and
consolidations.
 
NOTE 5 -- CONVERTIBLE PREFERRED STOCK
 
     The Company's Certificate of Incorporation allows the issuance of up to
4,000,000 shares of preferred stock. During fiscal 1998, the Company issued
25,000 shares of Series A Convertible Preferred Stock, par value $.01 per share,
stated value $1,000 per share (the "Series A Preferred Stock"), and 20,000
shares of Series B Convertible Preferred Stock, par value $.01 per share, stated
value $1,000 per share (the "Series B Preferred Stock").
 
     Dividends on the Series A Preferred Stock and Series B Preferred Stock
accrue, whether or not declared by the Board of Directors, at an annual rate of
6.0% and 4.5%, respectively, of the stated value of each outstanding share of
Series A Preferred Stock and Series B Preferred Stock. Dividends are payable in
cash, or at the Company's option, in additional shares of preferred stock.

     Due to the net loss applicable to Common Stock for the three months ended
June 30, 1998, the effect of dilutive stock options and warrants were not
included as their effect would have been anti-dilutive. However, if the Company
would have reported net earnings, the incremental shares attributable to
dilutive stock options and warrants would have been approximately 2,982,000.
Also, the potentially dilutive effect of the Company's convertible preferred
stock were not used in the diluted earnings per share calculation as its effect
was anti-dilutive.
 
NOTE 7 -- RECENTLY ISSUED ACCOUNTING STANDARDS
 
     SFAS No. 131, "Disclosures about Segments of an Enterprise and Related
Information," was issued by the FASB in June 1997. This Statement establishes
standards for reporting of selected information about operating segments in
annual financial statements and requires reporting of selected information about
operating segments in interim financial reports issued to shareholders. It also
establishes standards for related disclosures about products and services,
geographic areas and major customers. The Company will not be impacted by SFAS
No. 131.
 
     SFAS No. 132, "Employers' Disclosures about Pensions and Other
Postretirement Benefits," was issued by the FASB in February 1998. This
Statement revises employers' disclosures about pension and other postretirement
benefit plans. The Company will adopt SFAS No. 132 in fiscal 1999 and does not
expect the impact to be material to the Company.
 
     SFAS No. 133, "Accounting for Derivative Instruments and Hedging
Activities," was issued by the FASB in June 1998 and is effective for fiscal
years beginning after June 15, 1999. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments and for hedging activities. SFAS
No. 133 requires that an entity recognize all derivatives as either assets or
liabilities in the statement of financial position and measure those instruments
at fair value. The Company is evaluating SFAS No. 133 to determine its impact on
the consolidated financial statements.

     This Form 10-Q includes certain statements that may be deemed to be
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. Statements in this Form 10-Q which address
activities, events or developments that the Company expects or anticipates will
or may occur in the future, including such things as future acquisitions
(including the amount and nature thereof), business strategy, expansion and
growth of the Company's business and operations and other such matters are
forward-looking statements. Although the Company believes the expectations
expressed in such forward-looking statements are based on reasonable assumptions
within the bounds of its knowledge of its business, a number of factors could
cause actual results to differ materially from those expressed in any
forward-looking statements, whether oral or written, made by or on behalf of the
Company. These factors are set forth under the caption "Investment
Considerations" appearing in the Company's annual report on Form 10-K for the
year ended March 31, 1998, as the same may be amended from time to time. Some of
the factors which could affect the Company's performance include, among other
things: the effects of leverage on the Company, immediate and future capital
requirements, risk of dilution to existing shareholders, potential inability to
control growth or to successfully integrate acquired businesses, limited
operating history, cyclicality of the metals recycling industry, potential
inability to complete pending acquisitions, commodity price fluctuations,
compliance with environmental, health and safety and other regulatory
requirements applicable to the Company, potential environmental liability, risk
of deterioration in relations with labor unions, control by principal
stockholders and dependence on key management, dependence on suppliers of scrap
metals, concentration of customer risk, competition in the scrap metals
industry, availability of scrap alternatives, stock market volatility and year
2000 compliance.
 
ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS
 
     The following discussion should be read in conjunction with the unaudited
condensed consolidated financial statements and notes thereto included under
Item 1. In addition, reference should be made to the audited consolidated
financial statements and notes thereto and related Management's Discussion and
Analysis of Financial Condition and Results of Operations included in the
Company's Annual Report on Form 10-K for the year ended March 31, 1998 and in
the Company's Current Report on Form 8-K dated July 1, 1998.
 
GENERAL OVERVIEW
 
     Metal Management is one of the largest and fastest-growing full service
metals recyclers in the United States, with 59 recycling facilities in 15
states. The Company is a leading consolidator in the metals recycling industry
and has achieved this position primarily through the implementation of its
national strategy of completing and integrating regional acquisitions. The
Company believes that its consolidation strategy will enhance the competitive
position and profitability of the operations that it acquires through improved
managerial and financial resources and increased economies of scale.
 
     Metal Management is primarily engaged in the collection and processing of
ferrous and non-ferrous metals for resale to metals brokers, steel producers,
and producers and processors of other metals. The Company collects industrial
scrap and obsolete scrap, processes it into reusable forms, and supplies the
recycled metals to its customers, including mini-mills, integrated steel mills,
foundries and metals brokers. The Company believes that it provides one of the
most comprehensive offerings of both ferrous and non-ferrous scrap metals in the
industry. The Company's ferrous products primarily include shredded, sheared,
hot briquetted, cold briquetted and bundled scrap and broken furnace iron. The
Company also processes non-ferrous metals, including aluminum, copper, stainless
steel, brass, titanium and high-temperature alloys, using similar techniques and
through application of the Company's proprietary technologies.
 
     The Company's predecessor was incorporated on September 24, 1981 as a
California corporation under the name General Parametrics Corporation, and was
re-incorporated as a Delaware corporation in June 1986 under the same name.
Prior to April 1996, the Company manufactured and marketed color thermal and dye
sublimation printers and related consumables, including ribbons, transparencies
and paper. The Company sold this business in two separate transactions in July
and December of 1996 for $1.3 million in cash and future
 
                                       12
<PAGE>   15
 
royalty streams which the Company does not anticipate will result in material
payments to the Company. On April 12, 1996, the Company changed its name to
"Metal Management, Inc."
 
     The Company's Common Stock is traded on the NASDAQ Stock Market under the
trading symbol "MTLM". The Company's principal executive offices are located at
500 North Dearborn Street, Suite 405, Chicago, Illinois 60610, and its telephone
number is (312) 645-0700.
 
ACQUISITION STRATEGY
 
     In pursuing its acquisition strategy, the Company seeks to identify
companies that (i) have a successful operating history; (ii) are located in
major metropolitan or regional markets (population of 1,000,000 or more) and
present synergies with existing or planned acquisition candidates in a
particular region; (iii) offer strong management which can be retained following
an acquisition; (iv) complement the Company's regional and national customer
base; (v) have a history of high integrity in their management and operations;
(vi) have convenient access to water or rail transportation facilities; (vii) do
not present serious environmental or regulatory issues; and (viii) either have
existing shredder operations or the ability to support the installation of such
equipment. While a target company does not have to meet all of the acquisition
criteria, it is important that a metropolitan or regional "hub" company meet
most of the criteria and that other acquisition candidates that can complement
the operations of the "hub" company are identified within a region.
 
     Once an acquisition candidate has been identified, the Company conducts
financial, legal and operational due diligence investigations of the target
company. This due diligence investigation will generally include an
environmental site assessment and a review of the target company's environmental
compliance procedures and practices, a review of the legal and regulatory
affairs of the target, and a review of the target company's financial books and
records, including an independent audit of its financial statements, in certain
cases.
 
     The Company generally enters into multi-year employment contracts with
certain senior managers of the acquired company which often provide for
incentive compensation in the form of stock options and warrants. In addition, a
significant portion of the purchase price for an acquired company is often paid
in restricted Common Stock. The Company believes that these arrangements provide
strong incentives for the management of the regional operations to maximize the
operating performance of the Company's subsidiaries.
 
     Set forth below is a table identifying the recycling operations acquired by
the Company from April 1996 through August 14, 1998:

</TABLE>
 
     Consolidated net sales for the three months ended June 30, 1998 were $215.0
million compared with consolidated net sales of $82.1 million for the three
months ended June 30, 1997. The significant increase in consolidated net sales
is principally due to the inclusion of net sales of the companies acquired by
the Company since June 30, 1997.
 
     Ferrous sales of processed materials represented 51.3% of consolidated net
sales for the three months ended June 30, 1998 compared to 33.3% of consolidated
net sales for the three months ended June 30, 1997. The significant increase in
ferrous sales, both in tons sold and as a percentage of total net sales, is due
primarily to the inclusion of a full quarter's ferrous sales of Reserve and the
Isaac Group, which were acquired during the first quarter of fiscal 1998 and
ferrous sales of Proler and Cozzi, which were acquired subsequent to June 30,
1997.
 
     Non-ferrous sales of processed materials represented 30.8% of consolidated
net sales for the three months ended June 30, 1998 compared to 44.9% of
consolidated net sales in the three months ended June 30, 1997. The decrease in
the percentage of non-ferrous sales is due to the acquisitions of the Isaac
Group, Proler and Cozzi, which primarily sell ferrous metals. The increase in
pounds and dollars of non-ferrous metals sold is due to the inclusion of
non-ferrous sales of Superior Forge and Aerospace, which were acquired
subsequent to June 30, 1997. Superior Forge and Aerospace are primarily engaged
in the sale of non-ferrous and related metals.
 
     Brokerage ferrous sales represented 15.0% of consolidated net sales for the
three months ended June 30, 1998 compared to 11.1% of consolidated net sales for
the three months ended June 30, 1997. The increase in
 
                                       15
<PAGE>   18
 
brokerage ferrous sales is due to the inclusion of a full quarter's ferrous
brokerage sales of the Isaac Group which was acquired at the end of the first
quarter of fiscal 1998 and the acquisition of Cozzi.
 
     Brokerage non-ferrous sales represented 2.6% of consolidated net sales for
the three months ended June 30, 1998 compared to 10.3% of consolidated net sales
for the three months ended June 30, 1997. The Company's brokerage non-ferrous
sales are generated primarily by Bluestone. The decrease in the brokerage of
non-ferrous metals sold was due to a weakening in non-ferrous metals markets
during the three months ended June 30, 1998 versus the three months ended June
30, 1997.
 
     Consolidated gross profit was $19.7 million (9.2% of consolidated net
sales) for the three months ended June 30, 1998 compared with consolidated gross
profit of $7.4 million (9.0% of consolidated net sales) for the three months
ended June 30, 1997. The price of scrap metal is affected by regional and
seasonal variations. Furthermore, prices for scrap metal are also impacted by
broad and global cyclical movements and as such equilibrates supply and demand.
 
     Consolidated general and administrative expenses were $11.5 million (5.4%
of consolidated net sales) for the three months ended June 30, 1998 compared
with $4.2 million (5.1% of consolidated net sales) for the three months ended
June 30, 1997. The increase in general and administrative expenses primarily
reflects the inclusion of a full quarter of administrative expenses for those
operations acquired during the three months ended June 30, 1997 and the
inclusion of administrative expenses for those operations acquired subsequent to
June 30, 1997. Corporate overhead has also increased due to additions in
corporate staff and corporate expenses (i.e. legal, audit, travel, etc.) to
support the acquisition strategy the Company is pursuing.
 
     Depreciation and amortization expense was $4.4 million (2.0% of
consolidated net sales) for the three months ended June 30, 1998 compared with
$1.3 million (1.6% of consolidated net sales) for the three months ended June
30, 1997. The increase is attributed to the inclusion of goodwill amortization
and depreciation of fixed assets of those operations acquired by the Company
subsequent to June 30, 1997.
 
     During the three months ended June 30, 1998, the Company recorded merger
expenses of $0.9 million related to the Company's merger with Bluestone. Merger
expenses consist primarily of professional fees and expenses for accountants,
attorneys, and investment bankers as well as other related charges.
 
     Interest expense was $4.9 million (2.3% of consolidated net sales) for the
three months ended June 30, 1998, versus $1.5 million (1.9% of consolidated net
sales) for the three months ended June 30, 1997. The increase is primarily due
to the issuance of the Senior Subordinated Notes and additional borrowings made
by the Company from the Senior Credit Facility to fund acquisitions.
 
     Net loss from continuing operations, after preferred stock dividends, was
$1.6 million ($0.05 per share) for the three months ended June 30, 1998 compared
to a net income of $0.3 million ($0.02 per share) for the three months ended
June 30, 1997. The net loss from continuing operations is primarily attributable
to the recognition of merger expenses of $0.9 ($0.8 million net of income taxes)
million and declining prices for scrap metals during the three months ended June
30, 1998 as compared to the three months ended June 30, 1997. Net loss from
continuing operations excluding the merger expenses was $0.8 million ($.02 per
share) for the three months ended June 30, 1998.
 
     Income tax benefit for the quarter ended June 30, 1998 was $0.5 million,
which yields an effective tax rate of 29.8%. The effective tax rate differs from
the statutory rate primarily due to the permanent differences represented by
non-deductible goodwill amortization and other non-deductible merger expenses.
 
     During the three months ended June 30, 1998, the Company recognized an
extraordinary charge of $0.9 million, net of taxes, related to the early
retirement of debt and other costs incurred in connection with the closing of
the Senior Credit Facility. See Note 4 of the consolidated condensed financial
statements.
 
                        LIQUIDITY AND CAPITAL RESOURCES

     Cash Flows from Continuing Operations. The Company utilized $0.3 million of
cash in continuing operations during the three months ended June 30, 1998 versus
$6.3 million of cash which was utilized by continuing operations during the
three months ended June 30, 1997. Cash outflows from working capital during the

acquisitions completed during the three months ended June 30, 1998. During the
three months ended June 30, 1997, the Company purchased $1.0 million of property
and equipment and utilized cash of $6.3 million for acquisitions. The increase
in cash used for investing activities during the quarter is a result of
acquisitions completed during the quarter. Management anticipates the Company
will continue to make acquisitions, make capital expenditures for new equipment,
and upgrade and expand existing equipment and facilities. The Company expects
that these expenditures may increase in the future due to the internal growth of
the Company and business combinations.
 
     Cash Flows from Financing Activities. During the three months ended June

anticipates growing through acquisitions and will require additional debt and
equity to fund future acquisitions.

require principal payments of $10.8 million on February 15, 1999 and $10.8
million on February 15, 2000.
 
  Working Capital Availability and Requirements

     Property and equipment increased from $109.9 million at March 31, 1998 to
$136.4 million at June 30, 1998. During the quarter ended June 30, 1998, the
Company made capital expenditures of $4.8 million, bought-out certain operating
leases for $9.8 million, and acquired $15.4 million of property and equipment in
connection with the acquisitions completed during the quarter. The Company
expects to make substantial investments in additional equipment and property for
expansion, for replacement of assets, and in connection with future
acquisitions.
 
     At June 30, 1998, the Company had outstanding borrowings under its Senior
Credit Facility of approximately $0.1 million. Borrowings on the Senior Credit
Facility bore interest at an rate of 9.0% during the quarter. Amounts
outstanding under the Senior Credit Facility ranged from $0.0 to $121.7 million
during the quarter.
 
                              YEAR 2000 LIABILITY
 
     The Company is in the process of reviewing its existing computer software
systems, and in connection with that process is analyzing whether or not the
Company faces a "Year 2000" problem, a problem that is expected to arise with
respect to computer programs that use only two digits to identify a year in the
date field, and which were designed and developed without considering the impact
of the upcoming change in the century. Although the Company has not yet made a
final determination as to whether the various computer systems at its operations
will give rise to a "Year 2000" problem, the Company believes that any such
problem, if it arises in the future, should not be material to the Company's
operations.
