                               PROSPECTUS SUMMARY
 
     The following summary is qualified in its entirety by reference to the more
detailed information appearing elsewhere in this Prospectus or incorporated by
reference herein. All information herein giving effect to the offering made
hereby (the "Offering") assumes no exercise of the Underwriters' over-allotment
option. Except where the context otherwise requires, the term "Company" as used
herein refers to IMCO Recycling Inc. and its subsidiaries.
 
                                  THE COMPANY
 
     The Company is the largest aluminum recycler in the United States and
believes that it is the largest aluminum recycler in the world. The Company's
principal business is the processing of secondary aluminum, which includes used
aluminum beverage cans ("UBCs"), scrap, and dross (a by-product of aluminum
production). The Company converts UBCs, scrap and dross into molten metal in
furnaces at facilities owned and/or operated by the Company. The Company then
delivers the processed aluminum to customers in molten form or ingots. The
Company recovers magnesium in a similar process and also recycles zinc. Most of
the Company's processing capacity is utilized to recycle customer-owned
materials, for which the Company charges a fee (a service called "tolling").
During fiscal 1996, approximately 82% of the Company's total pounds of metal
processed involved tolling of aluminum. The balance of the Company's business
involves the purchase of scrap and dross for processing and recycling by the
Company for subsequent resale ("buy/sell" business).
 
     The Company's business has benefited from the trend to include recycled
aluminum in finished products as well as the growth in the production and
recycling of UBCs and the increasing utilization of aluminum in automotive
(including automobiles and trucks) components. Over the past two decades, U.S.
production of recycled aluminum has risen 184% while total U.S. aluminum supply
has increased only 82%. Recycled aluminum now constitutes approximately 34% of
overall aluminum supply, compared to 22% in 1976.
 
     The Company's customers include some of the world's major aluminum
producers and aluminum fabricators, diecasters, extruders and other processors.
Most of the metal processed by the Company is used to produce products for the
transportation, packaging and construction industries, which constitute the
three largest aluminum markets. Much of the Company's recent growth has been
directed toward serving the transportation sector, which has been the largest
and fastest-growing aluminum market in recent years due to the increasing use of
aluminum in automotive components.
 
GROWTH STRATEGY
 
     The Company's strategy is to participate in sectors of the nonferrous
metals recycling industry in which it believes it can provide customers with a
technology-based, value-added service and in which it can develop significant
market share. The Company believes that it has been successful in
differentiating its aluminum recycling services from those of its competitors
through (1) operational and design technologies that produce higher metal
recovery yields, (2) the strategic location of facilities in close proximity to
customers, providing for both stronger ties to its customers and greater
convenience and accessibility for its customers, (3) the ability to deliver
recycled aluminum in molten form for just-in-time delivery, thereby saving
customers the expense of remelting aluminum ingots and (4) advanced
environmental technology and practices, including dedicated disposal facilities
and a proprietary process used by the Company to recover aluminum from by-
products of the recycling process. To achieve its objectives, the Company
focuses on internal expansion as well as growth through strategic acquisitions,
vertical integration of its aluminum operations and services, operational
efficiencies through technological innovation, customer service and
environmental efficiencies.
 
     Strategic Expansion. Since 1993, the Company has increased its number of
facilities and capacity through acquisitions of existing facilities,
construction of new facilities, and expansion of existing facilities. As of
March 31, 1993, the Company owned and operated five recycling plants, which had
an aggregate annual processing capacity of 735 million pounds of aluminum and 50
million pounds of other metals. As of
                                        1
<PAGE>   5
 
August 31, 1997, the Company owned and operated 15 recycling and processing
plants, which have an aggregate annual processing capacity of 2,055 million
pounds of aluminum and 50 million pounds of other metals. In addition, the
Company owns a 50% interest in an aluminum recycling joint venture in Germany,
which has an annual melting capacity of 280 million pounds and is constructing
an aluminum recycling facility in Swansea, Wales, which will have an annual
melting capacity of 100 million pounds. The Company expects that currently
planned expansions of existing facilities will add approximately 145 million
pounds of annual processing capacity during 1998. See "Business -- Growth of
Business." Expansion of the Company's network of facilities in the U.S. has
enabled the Company to allocate processing work among its facilities, thereby
maximizing utilization of capacity and absorbing excess demand. The Company
intends to continue to expand its business by targeting growing markets, such as
the automotive market, constructing additional aluminum recycling facilities,
expanding and improving its existing facilities and acquiring or partnering with
similar recycling businesses or other metals processors. See "Recent
Developments -- Pending Alchem Acquisition" below. In addition, the Company
plans to continue seeking foreign sites for its recycling facilities where
market conditions warrant.
 
     Vertical Integration. The Company also seeks business opportunities that
combine its traditional recycling services with downstream processing operations
that more directly serve manufacturers and other end-users. For example, the
Company's acquisition of Rock Creek Aluminum, Inc. in early 1997 expanded the
Company's scope of activities from solely recycling operations to include the
mechanical processing of aluminum dross and scrap into deoxidization agents,
desulphurizers and slag conditioners to be sold to steel producers for use in
steel production. Further, the proposed acquisition of Alchem Aluminum, Inc., if
completed, will permit the Company to expand from molten metal deliveries to the
Alchem facility to the manufacture and sale of specification aluminum alloy
products for automotive equipment manufacturers. See "Recent Developments"
below.
 
     Technological Innovation. The Company's facilities and equipment have been
continually improved and updated through plant modernization programs, including
technological advancements designed to improve operational efficiencies. Between
January 1, 1992 and June 30, 1997, the Company made capital expenditures and
joint venture investments totaling $99 million in new plant and equipment
(excluding acquisitions of existing companies or facilities). These investments
have increased the Company's productivity, market share and total processing
capacity. During 1994 and 1995, the Company's facilities operated at greater
than 100% of their aggregate stated capacities. For the first eight months of
1997, the Company's capacity utilization rate was reduced to an average of
approximately 94%, primarily as a result of the addition of new capacity and the
commencement of operations at the Coldwater, Michigan facility. In August 1997,
the Company's facilities operated at 98% of their aggregate stated capacity.
 
     Customer Service. The Company is dedicated to maintaining customer
satisfaction and seeks to develop new methods and processes to better serve its
customers. The Company believes it provides its customers with the highest level
of service by offering (1) higher metal recovery rates, (2) a higher quality of
metal recovered, (3) advanced environmental technology and practices and (4)
conveniently located facilities. By December 1997, the Company expects to have
the capability to provide 74% of its processed aluminum in molten form. Through
long-term relationships with primary producers and other customers, the Company
maximizes its production capabilities while providing customers with a reliable
source for their product requirements. As of August 31, 1997, approximately 45%
of the Company's annual aluminum processing capacity was subject to multi-year
contracts, which generally contain price escalators directly related to
production costs, such as labor and natural gas expenses.
 
     Environmental Efficiencies. The Company is developing a "closed loop"
production system in which virtually all materials used in the recycling process
are reclaimed or consumed, thus greatly reducing the need for and expense of
landfilling. Management believes that considerable progress has been made in
this area through the operation of its Kentucky salt cake processing plant and
its patented wet-milling process employed to recycle salt cake at both its
Arizona facility and the SALTS joint venture. While no assurances can be given
that an economically efficient closed loop recycling system will be developed
for all of the Company's facilities and processes, management believes that
continued progress toward this goal is desirable for the Company's customers due
to the opportunities for cost savings and further assurances of environmental
safety. In addition,
                                        2
<PAGE>   6
 
customers benefit from the enhanced environmental facilities employed by the
Company, such as the lined landfill at its Morgantown, Kentucky facility, which
is built to hazardous waste standards. See "Business -- The Recycling Process."
 
GROWTH OF BUSINESS
 
     By implementing its growth strategy, the Company has (1) increased its
customer base, (2) expanded the geographic scope of its services, both
domestically and abroad and (3) enhanced its technological leadership in the
secondary aluminum recycling industry. Principal events in this regard have
been:
 
     - The acquisition in 1994 of Metal Resources, Inc. and subsequent expansion
       of its Loudon, Tennessee aluminum recycling facility.
 
     - The acquisitions in 1995 of Metal Mark, Inc. and its aluminum recycling
       facilities in Chicago Heights, Illinois and Sikeston, Missouri and the
       Ravenswood Aluminum, Inc. aluminum recycling facility in Bedford,
       Indiana.
 
     - The establishment in 1996 of the Company's aluminum recycling joint
       venture in Germany, the Company's first international venture.
 
     - The construction in 1996 of the Company's salt cake processing facility
       at Morgantown, Kentucky.
 
     - The construction in 1996 and 1997 of an aluminum recycling facility in
       Coldwater, Michigan.
 
     - The acquisitions in January 1997 of IMSAMET, Inc., which owns three
       aluminum processing and recycling facilities and Rock Creek Aluminum,
       Inc., which owns two aluminum processing facilities.
 
     - The construction of the Swansea, Wales aluminum recycling facility in
       1997.
 
     - The proposed acquisition of Alchem Aluminum, Inc., which operates a
       secondary aluminum production facility.
 
See "Business -- Growth of Business."
 
RECENT DEVELOPMENTS
 
     IMSAMET and Rock Creek Acquisitions. In January 1997, the Company completed
the acquisitions of IMSAMET, Inc. ("IMSAMET") and Rock Creek Aluminum, Inc.
("Rock Creek"). IMSAMET owns or has a majority interest in three aluminum
recycling plants located in Idaho, Arizona and Utah, and owns a 50% interest in
a facility in Utah, which uses a proprietary process to reclaim materials from
salt cake. IMSAMET's recycling facilities have a combined annual melting
capacity of 420 million pounds. Rock Creek operates two facilities in Ohio that
utilize milling, shredding, blending, testing and packaging equipment to process
various types of raw materials, including aluminum dross and scrap, into
deoxidation agents, desulphurizers and slag conditioners for use in the steel
industry. Rock Creek's facilities have a total annual processing capacity of
approximately 150 million pounds.
 
     Pending Alchem Acquisition. On September 18, 1997, the Company announced
that it had entered into a non-binding letter of intent to acquire all of the
capital stock of Alchem Aluminum, Inc. ("Alchem"), in exchange for cash and
1,208,339 shares of Common Stock (the "Alchem Acquisition"). Alchem is a
producer of specification aluminum alloys for automotive manufacturers and their
suppliers. Completion of the Alchem Acquisition will permit the Company to
increase its participation in the automotive industry, broaden its customer base
and expand its product range to include specification alloys. If the acquisition
is completed, the Company estimates that approximately 30% of its annual
domestic capacity will be dedicated to supplying the transportation sector. The
acquisition is expected to increase the Company's total annual processing
capacity in 1998 to approximately 2.6 billion pounds.
 
     The shares of Common Stock to be issued to the Alchem shareholders will be
contractually restricted from resale, and the Company plans to agree to grant
the Alchem shareholders certain registration rights with respect to such shares
of Common Stock. The amount of cash to be paid will be determined by deducting

aggregate amount of Alchem's obligations for borrowed money outstanding as of
the closing date of the acquisition from $26,250,000. At September 30, 1997, the
amount of Alchem's indebtedness for borrowed money outstanding was $13,416,000.
 
     Alchem has been operating its facility located in Coldwater, Michigan since
1972. Alchem and the Company have also been operating under a joint venture
agreement entered into in October 1995 to construct and operate an aluminum
recycling plant adjacent to Alchem's processing plant in Coldwater. This joint
venture plant began operating in February 1997 and is expected to reach full
capacity in October 1997. Alchem's facility has an annual processing capacity of
180 million pounds; the joint venture facility with the Company has an annual
capacity of 150 million pounds. For its fiscal year ended October 31, 1996,
Alchem had net sales of $112 million. For the six months ended June 30, 1997,
Alchem had net sales of $74 million. The Alchem Acquisition is expected to close
in October 1997; however, there can be no assurance of when or whether it will
be completed. See "Business -- Pending Alchem Acquisition."

                           FORWARD-LOOKING STATEMENTS
 
     Certain information contained in or incorporated by reference into this
Prospectus may be deemed to be forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933 and Section 21E of the Securities
Exchange Act of 1934 and is subject to the "Safe Harbor" provisions of those
sections. This information includes, without limitation, statements concerning
future revenues, future earnings, future costs, future margins and future
expenses; pending or future acquisitions or corporate combinations (including
the Alchem Acquisition), plans for domestic or international expansion, and
anticipated technological advances; future capabilities of the Company to
achieve "closed loop recycling" on a commercially efficient basis, prospects for
the Company's joint venture partners to purchase a portion of the Company's
interests, and future or extensions of existing long-term supply contracts with
its customers; the outcome of and any liabilities resulting from any claims,
investigations or proceedings against the Company or its subsidiaries; future
levels of dividends (if any), the future mix of business, future asset
recoveries, and future operations, future demand, future industry conditions,
future capital expenditures, and future financial condition. These statements
are based on current expectations and involve a number of risks and
uncertainties. Although the Company believes that the expectations reflected in
such forward-looking statements are reasonable, it can give no assurance that
such expectations will prove to be correct.
 
     When used in or incorporated by reference into this Prospectus, the words
"anticipate," "estimate," "expect," "may," "project" and similar expressions are
intended to be among the statements that identify forward-looking statements.
Important factors that could affect the Company's actual results and cause
actual results to differ materially from those results that might be projected,
forecast, estimated or budgeted by the Company in such forward-looking
statements include, but are not limited to, the following: fluctuations in
operating levels at the Company's facilities, the mix of buy/sell business as
opposed to tolling business, retention and financial condition of major
customers, effects of future costs, collectibility of receivables, the inherent
unpredictability of adversarial or administrative proceedings, effects of
environmental and other governmental regulations, currency exchange
fluctuations, the price of and demand for aluminum on world markets and future
levels and timing of capital expenditures.
 
     These statements are further qualified by the following: any estimates of
future operating rates at the Company's plants are based on current expectations
by management of the Company of future levels of volumes and prices for the
Company's services or metal, and are subject to fluctuations in customer demand
for the Company's services and prevailing conditions in the metal markets, as
well as certain components of the Company's cost of operations, including energy
and labor costs. Many of the factors affecting revenues and, costs are outside
of the control of the Company, including general economic and financial market
conditions and governmental regulation and factors involved in administrative
and other proceedings. The future mix of buy/sell vs. tolling business is also
dependent on customers' needs and overall demand, world and U.S. market
conditions then prevailing in the respective metal markets, and the operating
levels at the Company's various facilities at the relevant time.

York Stock Exchange was $18 5/8 per share.
 
     Dividends as may be determined by the Board of Directors may be declared
and paid on the Common Stock from time to time out of funds legally available
therefor. The credit agreement governing the Company's senior credit facility
(the "Credit Agreement") currently limits the aggregate annual amount of cash
dividends the Company can pay. The limitations are as follows: $3.5 million per
year for 1997 and 1998, $4.0 million per year for 1999 and 2000, and $6.0
million per year after 2000. The Company intends to continue paying dividends on

                                USE OF PROCEEDS
 
     The net proceeds from the sale of the shares of Common Stock offered hereby
at an assumed public offering price of $19 per share are estimated to be
approximately $53,650,000 ($61,772,500 if the Underwriters' over-allotment
option is exercised in full), after deducting underwriting discounts and
commissions and estimated Offering expenses to be paid by the Company.
 
     The Company intends to apply the net proceeds from the Offering to reduce
outstanding indebtedness under the Credit Agreement, which was originally
incurred in January 1997 to finance the IMSAMET acquisition and to refinance
outstanding indebtedness. Indebtedness under the Credit Agreement bears a
fluctuating interest rate based on LIBOR or the prime rate, plus a credit margin
that is based on the Company's ratio of total debt to earnings before interest,
taxes, depreciation and amortization. As of September 30, 1997, the effective
interest rate under the Credit Agreement was 7.5% per annum. The terms of the
Credit Agreement currently provide for a term loan, which has a final maturity
of seven years, and a revolving loan, which has a final maturity of five years.
The aggregate principal amount of indebtedness outstanding under the Credit
Agreement as of September 30, 1997 was $107,855,000. See "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion of the Company's financial condition and results
of operations should be read in conjunction with the consolidated financial
statements of the Company and the notes thereto included elsewhere in this
Registration Statement.
 
GENERAL
 
     Most of the Company's processing consists of aluminum, magnesium and zinc
tolled for its customers. To a lesser extent, the Company's processing consists
of buy/sell business, which involves purchases of scrap metal and dross for
processing and resale. The Company's buy/sell business revenues include the cost
of the metal, the processing cost, and the Company's profit margin in the
selling price. Tolling revenues reflect only the processing cost and the
Company's profit margin. Accordingly, the tolling business generally produces
lower revenues and costs of sales than does the buy/sell business. Changes in
the mix of these two businesses from time to time can cause revenues to vary
significantly from period to period while not significantly affecting gross
profit, since both types of business generally produce approximately the same
gross profit per pound of metal processed.
 
     During the 1990s, aluminum inventories on the worldwide commodity exchanges
have fluctuated from severe excesses to relatively balanced positions. In times
of excess, aluminum prices declined, negatively affecting the profitability of
the major aluminum producers who are some of the Company's largest customers.
Environments of low profitability for the Company's customers have inhibited,
during those times, the Company's ability to pass cost increases through to its
customers. In early 1994, worldwide inventories of aluminum began falling for a
number of reasons, including an increase in demand for aluminum, particularly in
the United States, and consequently prices for aluminum began to rise. During
1995, worldwide aluminum prices declined from their 1994 levels, particularly in
the fourth quarter, and continued to fall until the end of 1996. For the first
six months of fiscal 1997, the U.S. domestic aluminum industry has benefited
from increases in aluminum prices and an increase in demand. It is not possible
to predict the future price of aluminum or the level of worldwide inventories of
aluminum and whether, or to what extent, such factors will affect the Company's
future business.
 
     The following table sets forth for the periods indicated the total pounds
of material processed (aluminum, magnesium and zinc); the percentage of total
pounds processed represented by (i) tolled aluminum, (ii) purchased aluminum and
(iii) magnesium and zinc; total revenues and total gross profits:

RESULTS OF OPERATIONS
 
  Six Months Ended June 30, 1997 vs. Six Months Ended June 30, 1996
 
     Production. During the six months ended June 30, 1997, the pounds of metal
processed by the Company increased 25% to 922 million pounds, compared to the
739 million pounds processed during the six months ended June 30, 1996. Aluminum
processing at the Company's newest joint venture plant in Coldwater, Michigan
(which began production in March 1997) and the IMSAMET facilities (which were
acquired in January 1997) were the primary reasons for the increased production.
With the exception of its Bedford,
 
                                       15
<PAGE>   19
 
Indiana plant, the Company's other aluminum plants processed approximately the
same amount of material in the six months ended June 30, 1997 as they processed
in the six months ended June 30, 1996.
 
     Revenues. During the six months ended June 30, 1997, revenues increased 57%
to $159,127,000, compared to revenues of $101,183,000 during the six months
ended June 30, 1996. The acquisitions of IMSAMET and Rock Creek and the new
Coldwater, Michigan plant accounted for 86% of the revenue increase for the six
month period ended June 30, 1997. The remainder of the increase was due
primarily to the combination of higher aluminum selling prices and higher levels
of buy/sell business for the Company's other aluminum plants. As discussed
above, an increase in buy/sell business generally results in a much higher
increase in revenue than would be produced by a similar increase in tolling
business. During 1997, the Company has had additional metal for sale due to the
operation of its salt cake processing facilities in Morgantown, Kentucky
(constructed in 1996) and Goodyear, Arizona (acquired in 1997). The increase in
buy/sell business during the six months ended June 30, 1997 also resulted in
higher inventory levels during that period. Tolling activity represented 83% of
the Company's total pounds melted during the six months ended June 30, 1997, as
compared to 84% during the six months ended June 30, 1996.
 
     Gross Profit. During the six months ended June 30, 1997, gross profits
increased 42% to $22,277,000, compared to gross profits of $15,697,000 during
the six months ended June 30, 1996. The acquisitions of IMSAMET and Rock Creek
in January 1997 and the new Coldwater plant accounted for approximately 80% of
the increase in gross profits for the six months ended June 30, 1997. In
addition, gross profits during the six months ended June 30, 1997 were higher
due to the elimination of the operating loss at the Company's Corona, California
plant, which was closed in the third quarter of 1996, and higher aluminum
prices, which increased margins from the Company's buy/sell business.
 
     SG&A Expenses. During the six months ended June 30, 1997, selling, general
and administrative expenses increased 50% to $8,799,000, compared to $5,869,000
during the six months ended June 30, 1996. The $2,930,000 increase was due
principally to higher employee, professional, consulting and goodwill
amortization expenses associated with the IMSAMET and Rock Creek acquisitions.
 
     Interest Expense. During the six months ended June 30, 1997, interest
expense increased 130% to $3,659,000, compared to interest expense of $1,590,000
during the six months ended June 30, 1996. The increase in interest expense was
primarily attributable to the additional debt outstanding in the first six
months of 1997 (due to borrowings in January 1997 to fund the IMSAMET
acquisition) as compared to the same period of 1996. See "-- Liquidity and
Capital Resources" below.
 
     Extraordinary Item. In connection with the acquisitions of IMSAMET and Rock
Creek in January 1997, the Company borrowed funds under the Credit Agreement.
See "Liquidity and Capital Resources" below. A portion of the sums borrowed
under the Credit Agreement was used to retire substantially all of the Company's
outstanding indebtedness prior to its stated maturity. This early debt
retirement generated an extraordinary loss of $1,318,000 (net of income taxes of
approximately $850,000) for the first quarter of 1997. There was no
extraordinary item in 1996.
 
     Net Earnings. During the six months ended June 30, 1997, earnings before
provision for income taxes, minority interests and extraordinary item increased
12% to $10,088,000, compared to $9,043,000 during the six months ended June 30,
1996. This increase in earnings was primarily the result of higher gross
profits, which were in turn partially offset by the increases in selling,
general and administrative expenses and interest expense. During the six months
ended June 30, 1997, the Company's effective income tax rate was 40%, compared
to 39% during the six months ended June 30, 1996. For the six months ended June
30, 1997, net earnings decreased 19% to $4,529,000, compared to $5,561,000 for
the six months ended June 30, 1996, due principally to the extraordinary item in
the first quarter of 1997.
 
  Fiscal Year 1996 vs. Fiscal Year 1995
 
     Production. During 1996, the pounds of metal processed by the Company
increased 10% to 1,451 million pounds, compared to 1,323 million pounds
processed in 1995. Increases from the Bedford and Metal Mark
 
                                       16
<PAGE>   20
 
facilities (which were acquired during the fourth quarter of 1995) were the
principal reasons for the increase in production volumes.
 
     Revenues. During 1996, revenues increased 49% to $210,871,000, compared to
revenues of $141,167,000 in 1995. The percentage increase in revenues was
greater than the relative increase in volumes processed due to higher levels of
buy/sell business during 1996 as compared to 1995. The increased levels of
buy/sell business were principally attributable to the Metal Mark facilities
acquired in October 1995, which have historically maintained an approximate
one-to-one ratio of tolling to buy/sell business.
 
     Gross Profit. During 1996, gross profits decreased 17% to $25,538,000,
compared to gross profits of $30,939,000 in 1995. During the third quarter of
1996, the Company recorded charges in cost of sales totaling $4,177,000,
resulting from management decisions to close the Company's Corona, California
recycling facility and to accelerate the closure of the first cell of the
Company's dedicated solid waste landfill in Morgantown, Kentucky. The Corona
facility had operated far below its capacity and had recorded losses throughout
1996 due to a precipitous decline in demand for aluminum from the Far East, the
plant's largest market.
 
     Before these third quarter charges to cost of sales, 1996's gross profits
of $29,715,000 were 4% lower than 1995's gross profits. This decline was due to
higher energy and salt cake disposal costs and because the Company's Corona and
Bedford plants experienced lower operating rates than anticipated. In addition,
gross profits were affected negatively by a decline in industry conditions
during 1996.
 
     SG&A Expenses. During 1996, selling, general and administrative costs
increased 17% to $11,774,000, compared to $10,027,000 in 1995. This increase
occurred as a result of the addition of key personnel required to manage the
Company's accelerated growth since 1994 and because of the added selling,
general and administrative costs associated with acquisitions in 1995.
 
     Interest. During 1996, interest expense increased 219% to $3,421,000,
compared to interest expense of $1,073,000 in 1995. This increase was the result
of additional long-term debt outstanding during 1996 which was incurred to fund
the Company's fourth quarter 1995 acquisitions of the Metal Mark and Bedford
facilities, the first quarter 1996 investment in the Company's joint venture in
Germany and the 1996 construction of the new Coldwater, Michigan facility.
Interest income rose to $623,000 compared to $424,000 in 1995. This increase was
due to higher average balances of invested cash during 1996.
 
     Net Earnings. During 1996, the Company's income before income taxes
decreased 47% to $10,852,000, compared to $20,363,000 in 1995. As discussed
above, approximately 44% of this decrease was due to the additional third
quarter charges to costs of sales of $4,177,000, resulting from management
decisions to close the Company's Corona, California facility and to accelerate
the closure of the first cell of the Company's landfill in Morgantown, Kentucky.
Excluding these items, 1996's net income before income taxes would have been
$15,029,000, or 26% lower than 1995's net income before income taxes. This 26%
percentage decline was greater than the 4% decline in gross profits (excluding
the third quarter charges to cost of sales) due to the higher selling, general
and administrative expenses and the higher interest expense.
 
     The Company's lower income before income taxes caused the tax expense
provision to fall to $4,132,000 in 1996 compared to $7,893,000 in 1995. The
effective tax rate was approximately 38% in 1996 compared to 39% in 1995.
 
  Fiscal Year 1995 vs. Fiscal Year 1994
 
     Production. During 1995, the pounds of metal processed by the Company
increased 31% to 1,323 million pounds, compared to the 1,013 million pounds
processed in 1994. Increases from the Bedford and Metal Mark plants acquired
late in 1995, and the Loudon plant which was acquired in September of 1994 and
expanded in 1995, along with increased volume from all plant locations,
accounted for the higher production.
 
     Revenues. During 1995, revenues increased 40% to $141,167,000, compared to
revenues of $101,116,000 in 1994. The percentage increase in revenues was
greater than the percentage increase in volumes processed because the level of
buy/sell business was slightly greater in 1995 as compared to 1994.
 
                                       17
<PAGE>   21
 
     Gross Profit. During 1995, gross profits increased 37% to $30,939,000,
compared to $22,638,000 in 1994. Most of this increase was attributed to the
increased pounds processed during 1995.
 
     SG&A Expenses. During 1995, selling, general and administrative costs
increased 56% to $10,027,000, compared to $6,440,000 in 1994. This increase
occurred because of the addition of key personnel required to manage the
Company's accelerated growth and because of selling, general and administrative
costs associated with acquisitions accomplished during 1995.
 
     Interest. Interest expense was approximately the same amount in 1995 as it
was in 1994. During 1995, interest income increased 175% to $424,000, compared
to $154,000 in 1994; this increase was due to higher average balances invested
in cash.
 
     Net Earnings. During 1995, income before income taxes increased 49% to
$20,363,000, compared to $13,703,000 in 1994. During 1994, the Company recorded
nonrecurring litigation expenses related to a lawsuit which reduced 1994's
income before taxes by $1,635,000. Excluding this item, the increase for 1995
would have been approximately 33%, or an amount similar to the percentage
increases recorded in volumes processed and gross profits.
 
     In 1995, the Company's increased income before income tax and higher tax
rates caused income tax expense to rise 51% to $7,893,000, compared to
$5,232,000 in 1994. The effective tax rate was approximately 39% in 1995
compared to 38% in 1994.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     The Company has historically financed its operations from internally
generated cash, its working capital credit facilities and funds from long-term
borrowings.
 
  Cash Flows
 
     Cash Flows from Operations. During the six months ended June 30, 1997,
operations provided $16,870,000 of cash, compared to the $1,102,000 of cash used
during the six months ended June 30, 1996. Changes in the components of
operating assets and liabilities (excluding those attributable to investing and
financing transactions) were the principal reasons for this difference. In the
six months ended June 30, 1997, changes in operating assets and liabilities
provided $2,013,000 in cash, while in the six months ended June 30, 1996,
changes in operating assets and liabilities used $12,386,000 in cash. This
condition was attributable to an increase in the Company's buy/sell business,
which resulted in a significant usage of cash during the six months ended June
30, 1996. Income before noncash charges increased $3,573,000 during the six
months ended June 30, 1997 compared to the six months ended June 30, 1996, which
also increased 1997's net cash provided from operating activities. As of June
30, 1997, the relationship of current assets to current liabilities, or current
ratio, was 2.02 to 1, compared to 2.58 to 1 as of December 31, 1996.
 
     Operations provided cash of $6,744,000 in 1996, compared with $25,716,000
in 1995. Decreased earnings, along with an increase in working capital
requirements in 1996, were the primary factors causing the decline in cash
provided from operations. Changes in operating assets and liabilities resulted
in a net use of cash of $15,291,000 in 1996, compared to providing cash of
$2,591,000 in 1995. The 1996 decline was principally the result of increased
buy/sell activities which caused an increase in inventory levels and accounts
receivable. As of December 31, 1996, the Company's current ratio was 2.58 to 1
as compared to 2.41 to 1 as of December 31, 1995.
 
     Working capital fluctuates as the mix of buy/sell business and tolling
business changes for the reasons discussed above. The Company's working capital
requirements are expected to increase for the remainder of 1997 and in 1998 due
to anticipated higher levels of buy/sell business and increased processing
volumes due to the IMSAMET and Rock Creek acquisitions and, if completed, the
Alchem Acquisition (See "-- Effects of the Alchem Acquisition"), and the initial
operations at the two new plants in Coldwater, Michigan and Swansea, Wales.
Nonetheless, the Company believes that its cash on hand, the availability of
funds under its credit facilities and, after giving effect to the Offering, its
anticipated internally generated funds will be sufficient to fund its current
needs and meet its obligations for the foreseeable future.
 
                                       18
<PAGE>   22
 
     Cash Flows from Investing Activities. During the six months ended June 30,
1997, net cash used by investing activities increased 358% to $79,020,000,
compared to $17,270,000 for the six months ended June 30, 1996. The increase in
net cash used in the six months ended June 30, 1997 was primarily due to the
Company's first quarter 1997 acquisition of IMSAMET. In addition, during the six
months ended June 30, 1997, the total payments for property, plant and equipment
increased 325% to $19,026,000, compared to $4,480,000 for the six months ended
June 30, 1996.
 
     During 1996, net cash used by investing activities decreased 17% to
$30,345,000, compared to $36,406,000 in 1995, respectively.
 
     During 1996, capital spending for property, plant and equipment (excluding
acquisitions), increased 8% to $16,711,000, compared to $15,538,000 in 1995. The
construction of the new facility in Coldwater, Michigan was the most significant
capital spending project in 1996. Capital spending in 1995 was primarily for
construction of a new salt cake processing facility and a landfill expansion,
both in Morgantown, Kentucky. In 1996, the Company also invested approximately
$14,000,000 in the VAW-IMCO joint venture in Germany. In 1995, the acquisitions
of Bedford and Metal Mark required $20,137,000.
 
     Capital expenditures for property, plant and equipment in 1997 are expected
to total approximately $35,000,000. Major projects include the construction of
the new aluminum recycling facilities in Coldwater, Michigan and Swansea, Wales,
the expansion of the Company's Loudon, Tennessee facility, the relocation of the
Company's zinc recycling facility, the purchase of various environmental
equipment and the expansion of the Company's landfill in Morgantown, Kentucky.
 
     Cash Flows from Financing Activities. For the six months ended June 30,
1997, net cash provided from financing activities increased 219% to $59,861,000,
compared to $18,729,000 for the six months ended June 30, 1996. In connection
with its January 1997 acquisitions, the Company entered into the Credit
Agreement, borrowing $110,000,000 at the closing; the Company used approximately
$61,000,000 for the IMSAMET and Rock Creek acquisitions and $49,000,000 to
retire substantially all of the Company's then-outstanding debt. Financing
activities also included cash payments of $1,253,000 in dividends during the six
months ended June 30, 1997.
 
     During 1996, financing activities provided $19,993,000 in net cash,
compared to $16,514,000 during 1995. On May 8, 1996, the Company received net
proceeds of approximately $5,569,000 from the issuance of $5,740,000 principal
amount of Solid Waste Disposal Facilities Revenue Bonds (Series 1996) by the
City of Morgantown, Kentucky. These bonds were issued in connection with the
Company's construction of its salt cake processing plant in Morgantown, which
was completed in January 1996. The indebtedness under the 1996 bonds bears
interest at the rate of 7.65% per annum and matures on May 1, 2016. In April
1997, the Company received additional net proceeds of $4,450,000 from the
issuance of $4,600,000 of Solid Waste Disposal Facilities Revenue Bonds (Series
1997) by the City of Morgantown, Kentucky. These bonds were issued in connection
with the Company's expansion of its landfill in Morgantown and additional
construction costs of its salt cake processing facility in Morgantown. The
indebtedness under the 1997 bonds bears interest at the rate of 7.45% per annum
and matures on May 1, 2022.
 
     In September 1995, the Company borrowed $5,000,000 under a variable rate
converting revolving loan, pursuant to terms it had previously negotiated with a
commercial lending institution, in order to take advantage of expansion
opportunities and to acquire the Bedford and Metal Mark facilities. As of
December 31, 1996 the interest rate thereunder was 6.75%. In addition, in
November 1995, the Company borrowed $15,000,000 of unsecured debt, representing
half of the commitment the Company received from a private placement of notes.
The remaining $15,000,000 of notes were issued on April 1, 1996 with the
proceeds primarily used to fund the Company's investment in the VAW-IMCO joint
venture. The notes issued in 1995 and 1996 had fixed annual interest rates of
7.28% and 7.41%, respectively. Both of these notes were paid in full in January
1997 with funds borrowed under the Credit Agreement described below.
 
     In 1995, the Company increased its borrowing limit to $10,000,000 under a
restated revolving credit facility (the "Revolving Facility"). On May 31, 1996,
the Company further increased its limit to $12,000,000. Under the Revolving
Facility, the Company had a subfacility for the issuance of standby letters of
credit. To
 
                                       19
<PAGE>   23
 
meet working capital needs, on December 30, 1996, the Company drew $2,000,000
under this revolving facility at an interest rate of 8.25%. This debt was also
subsequently repaid in January 1997.
 
     The January 1997 Credit Agreement provides for up to $125,000,000 of senior
secured credit facilities consisting of a $105,000,000 term loan and a
$20,000,000 revolving credit facility. Of the $20,000,000 revolving credit
facility, $4,000,000 is to be used, as needed, by the Company for standby
letters of credit. As of June 30, 1997, the Company had $97,965,000 in total
borrowings outstanding under the term loan and $13,100,000 in total borrowings
outstanding under the revolving credit facility. The term loan has a fixed
maturity of seven years, and the revolving credit facility has a final maturity
of five years.
 
     As of June 30, 1997, the Company had standby letters of credit outstanding
under the Credit Agreement and with another commercial bank in the aggregate
amounts of $1,752,000 and $1,044,000, respectively.
 
     The Credit Agreement facilities bear a fluctuating interest rate based on
LIBOR or the prime rate, plus a credit margin which is based on the Company's
rate of total debt to earnings before interest, taxes, depreciation and
amortization. In order to reduce the floating interest rate exposure on the term
loan, the Company entered into an interest rate cap transaction ("Rate Cap
Transaction") with the administrative agent for the lending syndicate in April
1997. Under the terms of the agreement governing Rate Cap Transaction, the
floating interest rate for 40% of the term loan borrowings under the Credit
Agreement is capped at 8% per annum. The costs associated with this Rate Cap
Transaction will be amortized as interest expense over the four year term of the
agreement.
 
     The Credit Agreement imposes certain restrictions, including: (i) certain
prohibitions on additional indebtedness and limitations on acquisitions, subject
to certain exceptions, (ii) maintenance of certain financial ratios and (iii)
limitations on investments, dividends and capital expenditures. The limitations
on cash dividends are as follows: $3,500,000 per year for 1997 and 1998,
$4,000,000 per year for 1999 and 2000 and $6,000,000 per year after 2000. The
Credit Agreement is secured by substantially all of the Company's assets, a
first lien mortgage on seven facilities and a pledge of the capital stock of
substantially all of the Company's subsidiaries. Substantially all of the
Company's subsidiaries have also guaranteed the indebtedness under the Credit
Agreement.
 
     The Company is in the process of renegotiating the terms of the Credit
Agreement. See "-- Effects of the Alchem Acquisition" below.
 
  Other
 
     During the first quarter of 1997, the Company entered into forward sale
contracts and a series of put and call option contracts with a metals broker to
cover the future selling prices on a portion of the aluminum generated by the
Company's salt cake processing facility. These contracts are settled in the
month of the corresponding production. The contracts did not have a significant
effect on the Company's results of operations for the six months ended June 30,
1997.
 
     On May 8, 1997, Harvard Industries, Inc. ("Harvard") announced that it had
filed for protection under Chapter 11 of the U.S. Bankruptcy Code. The Company
sells aluminum to Doehler-Jarvis, Inc. ("Doehler-Jarvis"), a subsidiary of
Harvard. As of June 30, 1997, the Company had $3,530,000 of outstanding
unsecured receivables from Doehler-Jarvis (net of reflected reserve). Harvard
has previously indicated that it intends to pay 100% of all pre-petition claims
by vendors. While the Company currently believes that Harvard's bankruptcy will
not have a material adverse effect on the Company's financial position or
results of operations, no assurance can be given as to the amount and timing of
the Company's ultimate recovery, if any, of its claims. The Company's revenues
from Doehler-Jarvis totaled $12,955,000 and $17,490,000 for the six months ended
June 30, 1997 and the year ended December 31, 1996, respectively. The Company
believes that the loss of this customer will not have a material adverse effect
on the Company's financial position or results of operations.

  Effects of the Alchem Acquisition
 
     The closing of the Offering is not conditioned upon the closing of the
Alchem Acquisition, which is subject to the conditions contained in the letter
of intent and the proposed purchase agreement for such acquisition. Although the
Company believes that such conditions will be fully satisfied on or before the
closing date of the Alchem Acquisition, many of these conditions are beyond the
control of the Company and there can be no assurance of when or whether the
Alchem Acquisition will occur. See "Business -- Pending Alchem Acquisition."
 
     Since a high percentage of Alchem's business is buy/sell business and not
tolling, the Company expects to experience higher levels of buy/sell business
relative to tolling following the Alchem Acquisition. These higher levels of
buy/sell business are expected to increase the Company's working capital
requirements and subject the Company to a greater degree to risks associated
with price fluctuations in the aluminum market. At this time, the Company
estimates that, after giving effect to the Alchem Acquisition, its percentage of
annual total pounds processed represented by aluminum tolling transactions
should decrease from approximately 82% to approximately 77%.
 
     If the closing of the Alchem Acquisition does not occur, the financial
condition and business of the Company will be materially different than if the
acquisition is completed. For pro forma results of operations excluding the
Alchem Acquisition, see the Pro Forma Condensed Consolidated Financial
Statements included elsewhere in this Prospectus.
 
     Both the January 1997 acquisitions and indebtedness incurred to finance the
acquisitions and refinance the existing Company debt resulted in higher working
capital requirements and increased debt service requirements for the Company. In
addition, certain covenants contained in the Credit Agreement restrict the
aggregate amount of expenditures for acquisitions and investments, as well as
future capital expenditures in any fiscal year, that the Company may make. The
Company expects to obtain waivers from its lenders with respect to these
restrictions with regard to the Alchem Acquisition.
 
     Additionally, the Company is in the process of renegotiating the terms of
the Credit Agreement with its lenders. The Company expects to amend and restate
the Credit Agreement to consolidate the unpaid amount of the outstanding
indebtedness under the term facility with the revolving facility, resulting in a
reducing revolving credit facility of up to $175,000,000. The Company
anticipates that, assuming that the indebtedness under the reducing revolving
credit facility is fully drawn, the facility will be amortized in required
increasing annual repayments beginning in 1999, from $20 million in 1999 to $75
million in 2003. The Company also expects that the pricing and the terms of many
of the financial and other covenants of the Credit Agreement will be
renegotiated. Although the Company expects to amend and restate the Credit
Agreement by the end of October 1997, no definitive agreement to do so has yet
been executed, and no assurances can be given that the Credit Agreement will be
amended and restated by that time, or at all. See "Use of Proceeds."
 
     The closing of the Alchem Acquisition is not conditioned upon the amendment
and restatement of the Credit Agreement. However, the Company expects to fund
the cash portion of the consideration for the Alchem Acquisition and to repay
all or a portion of the Alchem indebtedness from borrowings under the amended
and restated Credit Agreement.
 
     Following the Alchem Acquisition, the Company plans to continue to pursue
acquisitions that meet its criteria and continue the construction of new
facilities and expansion of its existing plants, where demand and market
conditions warrant. The Company does not currently anticipate any significant
change in its estimated 1997 capital budget for property, plant and equipment of
$35 million. The Company believes that its sources of liquidity will continue to
be adequate to fund its cash requirements.

                                    BUSINESS
 
     The Company is the largest aluminum recycler in the United States and
believes that it is the largest aluminum recycler in the world. The Company's
principal business is the processing of secondary aluminum, which includes used
aluminum beverage cans ("UBCs"), scrap, and dross (a by-product of aluminum
production). The Company converts UBCs, scrap and dross into molten metal in
furnaces at facilities owned and/or operated by the Company. The Company then
delivers the processed aluminum to customers in molten form or ingots. The
Company recovers magnesium in a similar process and also recycles zinc. Most of
the Company's processing capacity is utilized to recycle customer-owned
materials, for which the Company charges a fee (a service called "tolling").
During fiscal 1996, approximately 82% of the Company's total pounds of metal
processed involved tolling of aluminum. The balance of the Company's business
involves the purchase of scrap and dross for processing and recycling by the
Company for subsequent resale ("buy/sell" business).
 
     The Company's business has benefited from the trend to include recycled
aluminum in finished products as well as the growth in the production and
recycling of UBCs and the increasing utilization of aluminum in automotive
(including automobiles and trucks) components. Over the past two decades, U.S.
production of recycled aluminum has risen 184% while total U.S. aluminum supply
has increased only 82%. Recycled aluminum now constitutes approximately 34% of
overall aluminum supply, compared to 22% in 1976.
 
     The Company's customers include some of the world's major aluminum
producers and aluminum fabricators, diecasters, extruders and other processors.
Most of the metal processed by the Company is used to produce products for the
transportation, packaging and construction industries, which constitute the
three largest aluminum markets. Much of the Company's recent growth has been
directed toward serving the transportation sector, which has been the largest
and fastest-growing aluminum market in recent years due to the increasing use of
aluminum in automotive components.
 
     The Company is a Delaware corporation with its principal executive offices
located at 5215 North O'Connor Blvd., Suite 940, Irving, Texas 75039. Its
telephone number is (972) 869-6575.
 
GROWTH STRATEGY
 
     The Company's strategy is to participate in sectors of the nonferrous
metals recycling industry in which it believes it can provide customers with a
technology-based, value-added service and in which it can develop significant
market share. The Company believes that it has been successful in
differentiating its aluminum recycling services from those of its competitors
through (1) operational and design technologies that produce higher metal
recovery yields, (2) the strategic location of facilities in close proximity to
customers, providing for both stronger ties to its customers and greater
convenience and accessibility for its customers, (3) the ability to deliver
recycled aluminum in molten form for just-in-time delivery, thereby saving
customers the expense of remelting aluminum ingots and (4) advanced
environmental technology and practices, including dedicated disposal facilities
and a proprietary process used by the Company to recover aluminum from by-
products of the recycling process. To achieve its objectives, the Company
focuses on internal expansion as well as growth through strategic acquisitions,
vertical integration of its aluminum operations and services, operational
efficiencies through technological innovation, customer service and
environmental efficiencies.
 
     Strategic Expansion. Since 1993, the Company has increased its number of
facilities and capacity through acquisitions of existing facilities,
construction of new facilities, and expansion of existing facilities. As of
March 31, 1993, the Company owned and operated five recycling plants, which had
an aggregate annual processing capacity of 735 million pounds of aluminum and 50
million pounds of other metals. As of August 31, 1997, the Company owned and
operated 15 recycling and processing plants, which have an aggregate annual
processing capacity of 2,055 million pounds of aluminum and 50 million pounds of
other metals. In addition, the Company owns a 50% interest in an aluminum
recycling joint venture in Germany, which has an annual melting capacity of 280
million pounds and is constructing an aluminum recycling facility in Swansea,
Wales, which will have an annual melting capacity of 100 million pounds. The
Company expects that currently planned expansions of existing facilities will
add approximately 145 million pounds of annual processing capacity during 1998.
See "Business -- Growth of Business." Expansion of the Company's network
 
                                       22
<PAGE>   26
 
of facilities in the U.S. has enabled the Company to allocate processing work
among its facilities, thereby maximizing utilization of capacity and absorbing
excess demand. The Company intends to continue to expand its business by
targeting growing markets, such as the automotive market, constructing
additional aluminum recycling facilities, expanding and improving its existing
facilities and acquiring or partnering with similar recycling businesses or
other metals processors. See "Recent Developments -- Pending Alchem Acquisition"
below. In addition, the Company plans to continue seeking foreign sites for its
recycling facilities where market conditions warrant.
 
     Vertical Integration. The Company also seeks business opportunities that
combine its traditional recycling services with downstream processing operations
that more directly serve manufacturers and other end-users. For example, the
Company's acquisition of Rock Creek Aluminum, Inc. in early 1997 expanded the
Company's scope of activities from solely recycling operations to include the
mechanical processing of aluminum dross and scrap into deoxidization agents,
desulphurizers and slag conditioners to be sold to steel producers for use in
steel production. Further, the proposed acquisition of Alchem Aluminum, Inc., if
completed, will permit the Company to expand from molten metal deliveries to the
Alchem facility to the manufacture and sale of specification aluminum alloy
products for automotive equipment manufacturers. See "Recent Developments"
below.
 
     Technological Innovation. The Company's facilities and equipment have been
continually improved and updated through plant modernization programs, including
technological advancements designed to improve operational efficiencies. Between
January 1, 1992 and June 30, 1997, the Company made capital expenditures and
joint venture investments totaling $99 million in new plant and equipment
(excluding acquisitions of existing companies or facilities). These investments
have increased the Company's productivity, market share and total processing
capacity. During 1994 and 1995, the Company's facilities operated at greater
than 100% of their aggregate stated capacities. For the first eight months of
1997, the Company's capacity utilization rate was reduced to an average of
approximately 94%, primarily as a result of the addition of new capacity and the
commencement of operations at the Coldwater, Michigan facility. In August 1997,
the Company's facilities operated at 98% of their aggregate stated capacity.
 
     Customer Service. The Company is dedicated to maintaining customer
satisfaction and seeks to develop new methods and processes to better serve its
customers. The Company believes it provides its customers with the highest level
of service by offering (1) higher metal recovery rates, (2) a higher quality of
metal recovered, (3) advanced environmental technology and practices and (4)
conveniently located facilities. By December 1997, the Company expects to have
the capability to provide 74% of its processed aluminum in molten form. Through
long-term relationships with primary producers and other customers, the Company
maximizes its production capabilities while providing customers with a reliable
source for their product requirements. As of August 31, 1997, approximately 45%
of the Company's annual aluminum processing capacity was subject to multi-year
contracts, which generally contain price escalators directly related to
production costs, such as labor and natural gas expenses.
 
     Environmental Efficiencies. The Company is developing a "closed loop"
production system in which virtually all materials used in the recycling process
are reclaimed or consumed, thus greatly reducing the need for and expense of
landfilling. Management believes that considerable progress has been made in
this area through the operation of its Kentucky salt cake processing plant and
its patented wet-milling process employed to recycle salt cake at both its
Arizona facility and the SALTS joint venture. While no assurances can be given
that an economically efficient closed loop recycling system will be developed
for all of the Company's facilities and processes, management believes that
continued progress toward this goal is desirable for the Company's customers due
to the opportunities for cost savings and further assurances of environmental
safety. In addition, customers benefit from the enhanced environmental
facilities employed by the Company, such as the lined landfill at its
Morgantown, Kentucky facility, which is built to hazardous waste standards. See
"Business -- The Recycling Process."

GROWTH OF BUSINESS
 
     Since 1992, the Company has grown its number of plant facilities and
capacity through acquisitions of existing facilities, construction of new
facilities and expansions of existing facilities. Beginning in 1994, this growth
strategy was accelerated.
 
     In September 1994, the Company purchased its aluminum recycling facility in
Loudon, Tennessee. In September 1995, the Company purchased all of the assets of
an aluminum recycling facility in Bedford, Indiana from Ravenswood Aluminum Inc.
In addition, in October 1995, the Company acquired Metal Mark, Inc. ("Metal
Mark"), which owned and operated aluminum recycling facilities located in
Chicago Heights, Illinois and Sikeston, Missouri. Metal Mark's principal
businesses are processing aluminum dross for domestic automotive producers and
manufacturers of castings for the automotive industry, and recycling aluminum
automotive scrap.
 
     In December 1995, the Company formed a joint venture, VAW-IMCO GuSS und
Recycling GmbH ("VAW-IMCO"), with VAW aluminium AG, the largest aluminum company
in Germany. The Company has a 50% interest in this German venture which owns and
operates two recycling and foundry alloy facilities. The plants principally
serve the European automotive markets.
 
     In January 1996, the Company completed the construction of a salt cake
processing facility which is located adjacent to the Company's Morgantown,
Kentucky plant. This facility processes salt cake, a by-product generated from
the Company's aluminum recycling plants, through the use of materials separation
technology, and recovers additional amounts of aluminum for resale that would
otherwise be landfilled. See "-- Environmental Matters."
 
     In 1996, the Company began construction of an aluminum recycling facility
in Coldwater, Michigan in a joint venture with Alchem. The Company is the 75%
managing member of the venture, which has a long-term supply agreement for the
delivery of hot metal to Alchem, the 25% member. See "-- Pending Alchem
Acquisition." The Coldwater plant started production during the first quarter of
1997 and will be equipped for full capacity in October 1997. The Company also
has recently entered into a commitment to construct with Alchem a joint venture
facility at the Company's Loudon, Tennessee site. This facility, which is
expected to begin production in March 1998, will supply molten metal to an
automobile has brake component manufacturer under a long-term scrap management,
tolling and supply agreement.
 
     In 1997, the Company also commenced construction of an aluminum recycling
facility in Swansea, Wales, U.K. Construction of the Wales facility is expected
to be completed in December 1997. The plant site is adjacent to a plant owned by
a subsidiary of Aluminum Company of America, Inc. ("Alcoa"), which will be its
principal customer under a long-term tolling agreement.
 
     In 1997, the Company began expansion programs at its Sapulpa and Loudon
facilities as well as at the one of the VAW-IMCO facilities in Germany. These
expansions, when completed in 1998, are expected to result in an additional 145
million pounds of processing capacity per year.
 
     In January 1997, the Company completed the acquisitions of IMSAMET and Rock
Creek. IMSAMET owns or has a majority interest in three aluminum recycling
plants located in Idaho, Arizona and Utah, and owns a 50% interest in a Utah
facility that uses a proprietary process to reclaim materials from salt cake.
IMSAMET's recycling facilities together have an annual melting capacity of 420
million pounds. Rock Creek operates two facilities in Ohio that utilize milling,
shredding, blending, testing and packaging equipment to process various types of
raw materials, including aluminum dross and scrap, into aluminum products used
as metallurgical additions in the steel making process. Rock Creek's facilities
have a total annual processing capacity of approximately 150 million pounds.
 
     At August 31, 1997, the Company owned and operated 15 domestic processing
and recycling plants located in ten states that have an aggregate annual melting
capacity of 2,055 million pounds of aluminum and approximately 50 million pounds
of other metals. As noted above, in addition to these wholly owned facilities,
the Company is a 50% owner of VAW-IMCO, which has a total annual processing
capacity of 280 million pounds of aluminum.

PENDING ALCHEM ACQUISITION
 
     On September 18, 1997, the Company announced that it had entered into a
non-binding letter of intent to acquire in a privately-negotiated transaction
all of the capital stock of Alchem, in exchange for cash and 1,208,339 shares of
Common Stock. The amount of cash to be paid will be determined by deducting from
$26,250,000 the aggregate amount of Alchem's obligations for borrowed money
outstanding as of the closing date of the acquisition. At September 30, 1997,
the amount of Alchem's indebtedness for borrowed money outstanding was
$13,416,000. A total of 150,000 shares of Common Stock will be held in escrow by
the Company for three years from the closing date of the acquisition as
potential recourse for the Company for breaches of representations and covenants
by the Alchem shareholders. All shares of Common Stock to be issued in
connection with the Alchem Acquisition will be contractually restricted from
resale. Pursuant to the terms of the purchase agreement to be entered into by
the Alchem shareholders and the Company, up to 350,000 shares of Common Stock
may be transferred after one year from the closing date, up to an additional
350,000 shares may be transferred after two years from the closing date and all
remaining shares may be transferred after three years. In addition, the Company
plans to grant "piggyback" registration rights beginning in 1998 and rights to
one demand registration commencing after the third anniversary of the closing
date to the Alchem shareholders with regard to the shares of Common Stock issued
in connection with the Alchem Acquisition. The Company intends to account for
the Alchem Acquisition using the purchase method of accounting.
 
     Alchem is a producer of specification aluminum alloys for automotive
manufacturers and their suppliers and has been operating its facility located in
Coldwater, Michigan, since 1972. Alchem and the Company have also been operating
under a joint venture agreement entered into in 1995 to construct and operate an
aluminum recycling plant adjacent to Alchem's processing facility in Coldwater.
This plant began operating in February 1997 and is expected to reach full
capacity in October 1997. Alchem's facility has an annual melting capacity of
180 million pounds; the joint venture facility with the Company has an annual
capacity of 150 million pounds. For its fiscal year ended October 31, 1996,
Alchem had net sales of $112 million. For the six months ended June 30, 1997,
Alchem had net sales of $74 million.
 
     The Alchem Acquisition will permit the Company to increase its
participation in the automotive industry, broaden its customer base and expand
its product range to include specification alloys. When the acquisition is
completed, it is estimated that approximately 30% of the Company's annual
domestic capacity will be supplied to the transportation sector. The acquisition
is expected to increase the Company's total 1998 processing capacity to
approximately 2.6 billion pounds.
 
     The closing of the Offering is not conditioned upon the closing of the
Alchem Acquisition, which will be subject to the conditions contained in the
letter of intent and in the purchase agreement to be entered into in connection
with the acquisition. Although the Company believes that such conditions will be
fully satisfied on or before the anticipated closing date of October 31, 1997,
many of these conditions are beyond the control of the Company and there can be
no assurance of when or whether the closing of the Alchem Acquisition will
occur. Closing conditions that remain unfulfilled include the satisfaction of
usual and customary closing conditions, including the absence of any injunction
or other legal restraint, the consent of third parties and governmental
entities, the accuracy in all material respects of the representations and
warranties made in the purchase agreement and the performance of pre-closing
agreements.
 
     Upon the closing of the Alchem Acquisition, it is expected that William
Warshauer, the primary shareholder of Alchem, his family and certain affiliates
of Alchem will own approximately 1.2 million shares of Common Stock, or 8.7 % of
the outstanding shares of Common Stock (7.2% after giving effect to the
Offering). See "Principal Stockholders."
 
     If the closing of the Alchem Acquisition does not occur, the financial
condition and business of the Company will be materially different than if the
acquisition is completed. See the Pro Forma Condensed Consolidated Financial
Statements and "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources."

PRODUCTS AND SERVICES
 
     The Company recycles aluminum and delivers the recycled metal to customers
as molten aluminum or ingots. The Company's customers include most of the major
United States aluminum producers, aluminum diecasters, extruders and other
processors of aluminum products. A principal element of the Company's strategic
plan calls for entering into new markets, specifically the expanding aluminum
automotive components market. In 1995, the Company entered this market with the
acquisition of Metal Mark and the formation of the VAW-IMCO joint venture. In
1996, the Company commenced construction of the Coldwater, Michigan joint
venture plant, which also serves this market.
 
     The Company's facilities and equipment have been continually improved and
updated through plant and equipment upgrades and modernization programs. Between
January 1, 1992 and June 30, 1997, the Company made capital and joint venture
investments totaling $99 million in new plant and equipment (excluding
acquisitions of existing firms or facilities). These investments have enabled
the Company to increase its productivity, market share and total processing
capacity.
 
     In addition, the Company plans to increase its emphasis on seeking foreign
sites for its recycling facilities where market conditions warrant. General
political and economic conditions in these countries could affect the overall
financial prospects of the Company. Foreign operations are generally subject to
several risks, including foreign currency exchange rate fluctuations, strict
environmental regulations, changes in the methods and amounts of taxation,
foreign exchange controls and government restrictions on the repatriation of
hard currency.
 
     The Company's business has benefited from the trend to include recycled
materials in finished products, and in particular, from the growth in the use
and recycling of aluminum beverage cans. The recycling of UBCs in the United
States has increased because of numerous economic, legislative and environmental
factors. According to industry estimates, the number of aluminum beverage cans
produced has increased from 34.7 billion in 1979 to an annual average of
approximately 100 billion for 1994 to 1996, and the number of UBCs recycled
increased from 8.5 billion to approximately 60 billion during the same period.
 
     The Company's principal customers include Alcoa, Kaiser Aluminum & Chemical
Corporation ("Kaiser"), Commonwealth Industries, Inc. ("Commonwealth"), Alumax
Inc. and Ravenswood Aluminum Corporation ("Ravenswood"), all of which use
aluminum recycled by the Company to produce can sheet, building construction
materials or automotive products.
 
     The Company also recycles magnesium dross for primary magnesium producers.
In addition, it produces a line of magnesium anodes that are recycled from
post-consumer scrap and sold to end users and independent distributors for
corrosion protection of steel structures.
 
     The Company believes that Interamerican Zinc, Inc., a subsidiary of the
Company ("IZI"), is the largest recycler of hot-dip zinc dross for continuous
galvanizers in the U.S. IZI's principal customers during 1996 and 1997 consisted
of most of the major U.S. steel companies.
 
     The Company's Rock Creek subsidiary manufactures a variety of aluminum
products and manufactures products that are eventually used as metallurgical
additions in the steel making process such as slag conditioners, deoxidizers,
steel desulfurizers and hot topping compounds. Rock Creek utilizes milling,
shredding, blending, testing and packaging equipment to process various types of
raw materials, including aluminum dross and scrap, into aluminum products for
the steel industry. In addition, Rock Creek manufactures a wide range of
proprietary briquetted products and offers toll briquetting services.
 
SALES AND LONG-TERM CONTRACTS
 
     The Company's principal customers (see "-- Products and Services") use
recycled aluminum to produce can sheet, building, automotive and other products.
The Company provides products and services to a number of primary and
fabricating facilities of Alcoa. For the first six months of 1997 and for 1996,
1995 and 1994, Alcoa accounted for approximately 10%, 13%, 23% and 30%,
respectively, of the Company's total revenues. Commonwealth accounted for
approximately 7%, 8%, 9% and 12% of revenues for the first six months of 1997
 
                                       26
<PAGE>   30
 
and for 1996, 1995 and 1994, respectively. The loss of either Alcoa or
Commonwealth as customers would have a material adverse effect upon the business
of the Company and its future operating results.
 
     Customarily, agreements with customers in the aluminum recycling industry
have been short-term. These usually result from a bidding process where aluminum
producers and metal traders offer to sell materials or to have materials tolled.
Consequently, the Company historically has maintained no significant backlog of
orders. However, the Company has secured some longer term commitments for its
recycling services with Alcoa, Commonwealth, Alchem, Aluminium Norf GmbH
("AluNorf"), Kaiser, Wise Metals Recycling LLC ("Wise Metals"), PBR Automotive
USA LLC and Ravenswood. As of August 31, 1997, approximately 45% of the
Company's annual aluminum processing capacity was subject to multi-year
contracts.
 
     The Company has entered into a 10-year supply contract with Commonwealth's
Uhrichsville plant to process all of that facility's scrap aluminum, UBCs and
dross at the Company's Uhrichsville plant. The agreement expires in 2002. See
"-- Properties." In 1994, the Company entered into a three-year processing
agreement with Alcoa under which the Company's Rockwood plant provides secondary
metal for its Alcoa, Tennessee facility. This agreement was modified in 1995 to
reflect greater volumes and to include the Company's Loudon plant as an approved
supplier under the terms of the contract. This agreement will extend for
additional one year terms at the end of each contract year unless terminated by
either party. If terminated by either party, the agreement will continue in
effect until the second anniversary date of the last day of the contract year
during which the termination notice was given.
 
     The Company has also entered into a similar supply agreement with an
English subsidiary of Alcoa pursuant to which the Company's Swansea facility
will provide Alcoa's adjacent facility with secondary tolled aluminum. The
agreement has a five-year primary term, to commence when initial operations
begin at the Company plant, with provisions for automatic three-year extensions.
In July 1997, the Company entered into a five and one-half year agreement with
Wise Metals to deliver ten million pounds of molten aluminum per month to supply
ARCO Aluminum Inc.'s Kentucky rolling mill.
 
     The Company's Post Falls, Idaho facility is subject to a processing
contract to supply, on a tolling basis, molten and ingot aluminum deliveries of
recycled can sheet and other aluminum scrap to Kaiser's nearby Trentwood,
Washington aluminum fabrication mill. The term of this agreement expires in June
1998, but the Company is negotiating and expects to secure a two-year extension
of the term of this agreement. In September 1997, the VAW-IMCO joint venture
entered into a five-year agreement with AluNorf to process 22,000 metric tons of
dross per year.
 
     Certain of these agreements contain cross-indemnity provisions, including
provisions obligating the Company to indemnify the supplier for certain
environmental liabilities that the supplier may incur in connection with the
transactions contemplated by the agreements.
 
     These agreements also typically contain escalation provisions that are
intended to cover changes in certain of the Company's processing costs. The
Company may seek similar dedicated long-term arrangements with customers in the
future. Increased emphasis on dedicated facilities to customers and dedicated
contracts with customers carries the inherent risk of increased dependence on a
single or few customers with respect to a particular Company facility. In such
cases, the loss of such a customer could have a material adverse effect on the
Company's financial condition and results of operation, and any timely
replacement of volumes attributable to such a customer could prove difficult.
 
     The primary metals industry and the metals recycling industry are subject
to cyclical fluctuations, depending upon the availability and price of
unprocessed scrap metal and the level of demand in the metal consuming
industries. Temporary reductions in can stock production by one of the Company's
customers have previously affected the Company's results of operations, and no
assurances can be given that such conditions will not recur.
 
THE RECYCLING PROCESS
 
     The raw material received for aluminum processing is loaded into furnaces
where natural gas heat is applied along with a flux mixture (salt and potash).
Some of the Company's aluminum facilities operate
 
                                       27
<PAGE>   31
 
rotary furnaces, which are significantly more flexible than reverberatory
furnaces and can process UBCs, dross and various types of aluminum scrap. The
Company believes that its rotary furnaces are more efficient and cleaner than,
and provide rates of recovery superior to, conventional rotary furnaces.
 
     Materials are melted in the furnaces, and the recovered metal is poured
directly into an ingot mold or hot metal crucible for delivery to customers.
Magnesium is recycled by the same method in a rotary furnace at the Sapulpa,
Oklahoma plant. Some of the Company's plants deliver molten aluminum in
crucibles directly to their customers' manufacturing facilities. The molten
aluminum is poured directly into the customer's furnace, saving the customer the
time and expense of remelting aluminum ingots. The Company normally charges an
additional fee for transportation and handling of molten aluminum. The Sapulpa,
Oklahoma, Goodyear, Arizona, Wendover, Utah and the Metal Mark plants are
restricted, due to the geographical locations of their customers, to delivering
the aluminum in ingot form.
 
     The aluminum recycling process from the Company's rotary furnaces produces
a by-product called "salt cake," which is formed from the contaminants and
coatings on aluminum scrap and dross and the salts added during the aluminum
recycling process. Salt cake is composed of salts, metallic aluminum, aluminum
oxide and small amounts of other materials. The by-product of processing
materials through reverberatory furnaces is dross.
 
     The Company disposes of its salt cake and certain airborne contaminants
("baghouse dust") in landfills that are used exclusively by the Company or that
are permitted specifically to handle the types of materials generated by the
Company. Salt cake is not currently listed as a "hazardous waste" under the
Resource Conservation and Recovery Act of 1976 ("RCRA") or as a "hazardous
substance" under the Comprehensive Environmental Response, Compensation and
Liability Act of 1980 ("CERCLA"). The Company has built and operates a lined
landfill at its Morgantown facility, the design of which exceeds current
requirements for disposal of salt cake and meets RCRA Subchapter "C" hazardous
waste standards.
 
     In 1996, the Company completed the construction of a facility adjacent to
its Morgantown plant to further process the salt cake through the use of
materials separation technology and extract additional aluminum that is left
after the melting process. The Company believes that this salt cake processing
facility is a critical step needed for "closed loop recycling," involving no or
minimal waste disposal. The facility's process involves crushing the salt cake
and separating the aluminum out of the salt cake. The residual product is then
landfilled in the Company's Morgantown landfill. See "-- Environmental Matters."
 
     The Company's IMSAMET facilities also recycle salt cake and other
by-products from the aluminum recycling process. The IMSAMET Arizona facility
processes aluminum scrap and turnings and recycles concentrates from purchased
dross and salt cake. These concentrates are first treated in the facility's
patented wet milling process, which reduces the volume of material handled, thus
allowing for more efficient utilization of capacity. Aluminum oxide, a
by-product of the wet milling process, is further treated and sold for use in
the production of cement.
 
     Located near the Bonneville Salt Flats, the IMSAMET Utah facility processes
aluminum concentrates from the adjacent 50% owned joint venture, Solar Aluminum
Technology Services ("SALTS"), and produces ingot. The SALTS facility recycles
salt cake from the IMSAMET Idaho and Utah plants into aluminum concentrates,
aluminum oxide and salt brine. The clear brine is delivered to the venture's
partner, where its chemical content is recycled for multiple uses, including
reuse as a flux.
 
     In IZI's zinc recycling process, dross is first melted in an electric
induction furnace and then transferred to a reactor which removes the impurities
(iron and zinc oxide, which are sold as a by-product). The remaining molten zinc
is poured into a reverberatory holding furnace in which it is blended and then
cast into ingots, which are returned to customers. IZI holds patent rights to
its process in the United States and 13 other countries.

(a) The acreage at Morgantown, Kentucky includes both the aluminum and salt cake
    processing facilities as well as landfill cells.
 
(b) The Company's former Adrian, Michigan facility had been leased by IZI. This
    lease expired in September 1997. This facility was relocated to a
    Company-owned site adjacent to the Coldwater, Michigan joint venture
    facility in September 1997.
 
(c) These facilities are leased.
 
(d) These facilities process salt cake only.
 
(e) These facilities process aluminum products for use in the steel industry.
 
(f) Represents 100% of the capacity of these facilities. The Goodyear, Arizona
    facility is 70% owned by the Company and the Coldwater, Michigan aluminum
    recycling facility is 75% owned by the Company.
 
(g) Represents 100% of the capacity of the two VAW-IMCO facilities.
 
     The average operating rates for all of the Company's facilities for 1994,
1995 and 1996 were 101%, 106%, and 92%, respectively, of stated capacity. The
lower operating rate during 1996 was due principally to the effect of the
closure of the Company's Corona, California facility during the third quarter of
1996. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
     Commonwealth has a currently exercisable option to acquire up to a 49%
equity interest in the Uhrichsville plant at a price equal to the equity
percentage amount specified by Commonwealth, multiplied by the depreciated book
value of the plant, or the subsidiary owning the plant, plus a premium to
compensate the Company for its recycling technology. The option price may be
above or below the fair value of the Uhrichsville plant. Should Commonwealth
exercise its option, there can be no assurance that the production
 
                                       29
<PAGE>   33
 
or earnings attributable to the purchased interest could be replaced, and the
Company's net earnings and cash flow could be adversely affected.
 
     In 1996, the Company began its 50% participation in the VAW-IMCO joint
venture in Germany. The venture owns and operates two recycling and foundry
alloy facilities located at Grevenbroich and Toging, Germany. Annual melting
capacity for these two plants is approximately 280 million pounds.
 
     The Company's new aluminum recycling facility in Coldwater, Michigan is 75%
owned by the Company and 25% owned by Alchem, the facility's primary customer.
The facility, when fully completed in October 1997, will contain three furnaces
with a total annual capacity of 150 million pounds and will primarily serve the
automotive market. The Company is the operator of the facility and delivers
molten aluminum to Alchem. Alchem currently has certain rights to purchase
additional equity interests in the venture, not to exceed 40% of the total joint
venture equity, if the facility is expanded or if Alchem increases its supply
commitments. See "-- Pending Alchem Acquisition."
 
     In 1997, the Company began constructing an aluminum recycling facility in
Swansea, Wales, U.K. Construction of the Wales facility is expected to be
completed in December 1997. The facility will have two furnaces and will have an
annual capacity of 100 million pounds, approximately 53 million of which are
dedicated to a multi-year contract with Alcoa. See "-- Sales and Long Term
Contracts."
 
     Solid Waste Disposal Facilities. The Company completed a new landfill cell
adjacent to its plant in Morgantown, Kentucky in 1996. All of the waste
generated from the salt cake processing facility at the Morgantown site is
deposited in this landfill. Management anticipates that this new landfill cell,
which is designed to be expanded several times throughout its life, will serve
the Company's landfilling needs for the majority of the salt cake generated by
facilities currently owned by the Company in the Eastern United States. In late
1997, the Company expects to begin construction on the first expansion phase of
this landfill cell. The Company also owns a landfill at its Sapulpa, Oklahoma
plant which is estimated to have three years useful life remaining. The IMSAMET
Arizona facility recycles its own salt cake and sells the by-products to third
parties, and the Utah and Idaho facilities ship their salt cake to the 50%-owned
SALTS joint venture for further processing. See "-- The Recycling Process."
 
     Administrative Facilities. In Irving, Texas, the Company leases
approximately 21,700 square feet of office space for certain of its executive,
financial and management functions. This lease expires in January 2000.
 
     The Company believes that its plants and equipment are maintained in good
operating condition. Substantially all of the properties and equipment at the
Company's plants are mortgaged to secure its senior indebtedness.
 
OPERATIONS
 
     In its aluminum tolling operations, the Company accepts UBCs, dross and
scrap owned by its customers and processes this material for a tolling charge
per pound of incoming weight. In order to retain control of their metal
supplies, customers have typically desired to toll, rather than sell, their
scrap materials. Tolling requires no metal inventory to be purchased or held by
the Company. In addition, tolling limits the Company's exposure to the risk of
fluctuating metal prices since the Company does not own the material being
processed. The Metal Mark acquisition and the operation of the Morgantown,
Kentucky salt cake processing facility have changed the Company's historical
ratio of tolling to buy/sell business. Only about 50% of Metal Mark's business
has traditionally involved tolling; the remainder is buy/sell business. The
Alchem Acquisition will further increase the Company's percentage of buy/sell
business. "See "Management's Discussion and Analysis of Financial Condition and
Results of Operations -- Liquidity and Capital Resources -- Effects of the
Alchem Acquisition."
 
     When purchasing metals in the open market for its buy/sell business, the
Company attempts to reduce the risk of fluctuating metal prices by arranging for
the sale of the aluminum anticipated to be recovered and by avoiding large
inventories of ingot or scrap material except to the extent necessary to allow
its plants to
 
                                       30
<PAGE>   34
 
operate without interruption. See also "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Liquidity and Capital
Resources."
 
     The Company constantly seeks improvements in operational efficiencies at
its existing plants and at its acquired facilities through technological
advancements, automation of its operational procedures, and modifications in
processing and material throughput methods. For example, the Wendover, Utah
plant for the first six months of 1996 (prior to the Company's acquisition),
recorded a net operating loss of approximately $400,000 on processing volumes of
25.5 million pounds. For the first six months of 1997, this same plant recorded
a net operating profit of $100,000 on processing volumes of 26.6 million pounds,
which the Company believes is largely due to the Company's implementation of
operational efficiencies at the plant following its acquisition.
 
     The Company's production network of plants have generally achieved high
overall operating rates due to strong demand for the Company's recycling
services and the strategic location of many of the Company's plants nearby major
customers' production facilities. Expansion of the Company's network of
facilities in the U.S. has enabled the Company to allocate processing work among
its facilities, thereby maximizing utilization of available capacity and taking
advantage of excess demand.
 
     The Company also believes that its advanced scrap preparation equipment and
recycling technologies have also increased the demand for its services by
producing higher recovery rates for the aluminum processed and better quality of
its recycled aluminum than many of its competitors.
 
COMPETITION
 
     The aluminum recycling industry is fragmented and highly competitive. The
Company believes that its position as the largest U.S. recycler of secondary
aluminum is a positive competitive factor. The principal factors of competition
in the industry are price, recovery rates, environmental and safety regulatory
compliance, and services (e.g., the ability to deliver molten aluminum). Freight
costs also limit the geographic areas in which the Company can compete
effectively.
 
     The major aluminum producers, some of which are the Company's largest
customers, have generally discontinued processing dross, instead focusing their
resources on other aspects of aluminum production. UBCs and other scrap are
processed by both the secondary recycling industry and the major producers. The
Company competes both with other secondary recyclers and their customers when
purchasing and processing scrap for the buy/sell business.
 
     The amount of the Company's tolling business can also vary depending upon
the extent that the major aluminum producers' used metal materials are
internally recycled. The aluminum producers generally vary their rate of
internal recycling depending upon furnace availability, inventory levels, the
price of aluminum, and their own internal demand for metal. The major aluminum
producers are larger and have greater financial resources than the Company. A
decision by these producers to expand their recycling operations could reduce
demand for certain of the Company's products and services.
 
SOURCE AND AVAILABILITY OF RAW MATERIALS AND ENERGY
 
     Except as noted below, the Company has historically not had, and does not
anticipate having, difficulties in obtaining raw materials for its operations.
In the case of buy/sell business, the primary sources of aluminum and magnesium
for recycling are dross and scrap, which are purchased from both the major
aluminum producers and metal traders.
 
     Prior to 1996, fluctuations in market prices for both aluminum and
magnesium had not significantly affected the availability of these metals to the
Company. However, during 1996, the Company had difficulty obtaining significant
quantities of UBCs to operate at a profitable level at its Corona, California
and Bedford, Indiana facilities, since these plants were then designed to
process only UBC material. As a result, management decided to close the Corona
facility in 1996. At the Bedford facility, the Company has modified one of the
existing furnaces and installed an additional furnace which will enable it to
process a greater variety of aluminum scrap in the future, including processing
for the automotive industry.
 
                                       31
<PAGE>   35
 
     The availability of zinc dross is dependent upon the demand for galvanized
steel, which has historically paralleled fluctuations in customer demand in the
automotive, appliance and construction industries.
 
     The Company's operations are fueled by natural gas, which represents the
second largest component of operating costs. In an effort to acquire the most
favorable natural gas costs, the Company has, at times, secured long-term supply
commitments for its natural gas requirements. Occasionally, when deemed
necessary, the Company purchases its natural gas on a spot-market basis. Most of
the Company's long-term supply contracts with its customers contain natural gas
price escalators. The Company may, from time to time, fix its natural gas costs
by entering into supply or hedging agreements with its suppliers. The Company
understands that most of its competitors' operations also are fueled by natural
gas; therefore, it believes that increases in the prices for natural gas do not
adversely affect the Company's competitive position. The Company believes it
will continue to have access to adequate energy supplies to meet its needs for
the foreseeable future.
 
SEASONALITY
 
     UBC collections have historically been highest in the summer months and
lowest in the winter months. Therefore, the Company has at times experienced
lower volumes during the winter. In recent years, however, the Company's
processing volumes have fluctuated mostly due to its startup of additional
capacity rather than the seasonality of UBC collections.
 
TRANSPORTATION
 
     The Company receives UBCs, dross and scrap, and ships its recycled metal by
both rail and truck. Most of the Company's plants own their own rail siding or
have access to rail lines nearby. The Company owns and leases various trucks and
trailers to support its business. Customarily, the transportation costs of scrap
materials to be tolled are paid by the Company's customers, while the
transportation costs of aluminum and magnesium purchased and sold by the Company
may be paid either by customers or the Company.
 
EMPLOYEES
 
     As of June 30, 1997, the Company had 1,250 employees, consisting of 265
employees engaged in administrative and supervisory activities and 985 employees
engaged in production and maintenance. The production and maintenance employees
at the Rockwood plant are represented by the United Steelworkers of America
under a five-year collective bargaining agreement that expires in August 2000.
The production and maintenance workers at the Uhrichsville plant are represented
by the United Mine Workers of America under an agreement that expires on
November 30, 1998. The production and maintenance workers at the Bedford plant
are represented by the International Brotherhood of Electrical Workers under an
agreement that expires in April 2000. The production and maintenance workers at
the Sikeston plant are represented by the United Steelworkers of America under
an agreement which expires in March 2001. Labor relations with employees have
been satisfactory.
 
     Alchem currently employs 195 employees, 48 of whom are engaged in
administrative and supervisory activities and 147 of whom are engaged in
production and maintenance. None of the Alchem employees are represented by a
union.
 
ENVIRONMENTAL MATTERS
 
     The Company's operations, like those of other basic industries are subject
to federal, state, local and foreign laws, regulations and ordinances that (i)
govern activities or operations that may have adverse environmental effects,
such as discharges to air and water, as well as handling and disposal practices
for solid and hazardous wastes, and (ii) impose liability for the costs of
cleaning up, and certain damages resulting from, past spills, disposals, or
other releases of hazardous substances (together, "Environmental Laws"). It can
be anticipated that more rigorous Environmental Laws will be enacted that could
require the Company to make substantial expenditures in addition to those
referred to herein, including future regulations, under the Federal Clean Air
Act ("CAA") and otherwise, which are expected to impose stricter emission
requirements
 
                                       32
<PAGE>   36
 
on the aluminum industry. While the Company believes that current pollution
control measures at most of the emission sources at its facilities will meet
these anticipated future requirements, additional measures at some of the
Company's facilities may be required.
 
     The Company's operations may generate certain discharges and emissions,
including in some cases off-site dust and odors, which are subject to the CAA
and other Environmental Laws. From time to time, operations of the Company have
resulted or may result in certain noncompliance with applicable requirements
under Environmental Laws. In addition, historical or current operations at or in
the vicinity of the Company's facilities may have resulted in soil or
groundwater contamination. However, based on environmental investigations
conducted by the Company and its consultants and certain indemnities associated
with the Company's acquisitions, the Company believes that any such
noncompliance or liability under current Environmental Laws would not have a
material adverse effect on the Company's financial position.
 
     In 1996, the Company entered into a settlement agreement with the Missouri
Department of Natural Resources ("MDNR") pertaining to certain air violations at
its Sikeston facility. Since entering into the settlement agreement, the Company
has received additional notices of violation from the MDNR, which relate to
fugitive dust emissions from its truck loading and unloading operations and
certain other air compliance matters. In addition, the Company recently
responded to a request for information from the United States Environmental
Protection Agency regarding air issues at the Sikeston facility. Since
purchasing the Sikeston facility in 1995, the Company has made significant
upgrades to the air pollution control equipment located at the facility. There
can be no assurance, however, that future violations will not occur or that the
violations identified by the MDNR will not result in enforcement action against
the Company.
 
     The processing of UBCs, dross and scrap generates solid waste in the form
of salt cake and baghouse dust. Currently, such material is either disposed of
at off-site landfills or at the Company's permitted Sapulpa and Morgantown
disposal sites. For example, the Rockwood, Loudon and Bedford plants currently
dispose of the majority of their solid waste by transporting it to the
Morgantown plant where the Company, in 1996, began operating a salt cake
processing facility which prepares salt cake for landfilling. At the
Uhrichsville plant, under the Company's supply agreement with Commonwealth, the
disposal of all salt cake generated by the Company as a result of its processing
for Commonwealth is the responsibility of Commonwealth. Salt cake from all other
material processed at the Uhrichsville plant is either shipped to the Morgantown
plant for disposal or landfilled with a local solid waste management firm. In
1996, the Chicago Heights and Sikeston plants disposed of the majority of their
salt cake with third-party landfills; however, a portion of their salt cake was
shipped to Morgantown. The IMSAMET Arizona facility recycles its own salt cake
and sells the by-products to third parties, and the Utah and Idaho facilities
ship their salt cake to the 50%-owned SALTS joint venture for further
processing. See "The Recycling Process."
 
     If salt cake were ever classified as a hazardous waste or substance under
RCRA or CERCLA, the Company's handling and disposal of salt cake would be
required to be modified. To dispose of its salt cake, the Company may then be
required to take other actions including obtaining a RCRA Subchapter "C" permit
for its Morgantown landfill, obtaining other permits (including transportation
permits), and consider landfilling additional amounts of salt cake with third
parties not under the Company's direct control. Based on current annual
processing volumes and remaining landfill capacity, the estimated remaining life
of the landfill at the Sapulpa plant is three years. The Company has constructed
a landfill at its Morgantown plant and estimates its remaining useful life to be
approximately eighteen months. Later this year, the Company expects to begin
construction on its first expansion phase at this landfill cell and estimates
that once completed, this expansion cell will have a remaining useful life of
approximately five years. A planned second expansion is expected to provide an
additional ten years of useful life. Landfill closure costs for the
Company-owned landfills are currently estimated to exceed $4,000,000. The
Company is currently providing for this expenditure by accruing, on a current
basis, these estimated costs as the landfills are used.
 
     In addition, the Company may incur liability for off-site disposals of salt
cake and other materials. In that regard, the Illinois Environmental Protection
Agency ("IEPA") recently notified IZI that it may be a potentially responsible
party ("PRP") pursuant to the Illinois Environmental Protection Act for the
cleanup of contamination at a site in Marion County, Illinois to which IZI,
among others, in the past sent zinc oxide
 
                                       33
<PAGE>   37
 
for processing and resale. IZI has joined a group of PRPs which is planning to
negotiate with the IEPA regarding the cleanup of the site. Although the site has
not been fully investigated and final cleanup costs not yet determined, based on
current cost estimates and information regarding the amount and type of
materials sent to the site by IZI, the Company does not believe, although there
can be no assurance, that its liability at this site will have a material
adverse effect on its financial position.
 
     Due to relatively high costs and limited coverage, the Company does not
carry environmental impairment liability insurance. The Company made capital
expenditures for environmental control facilities of approximately $3.8 million
in 1996, most of which was for landfill capacity additions. Estimated
environmental expenditures for 1997 and 1998, which primarily relate to the
Company's landfills and air pollution control projects, are approximately $6.3
million and $4.8 million, respectively.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 20,000,000 shares
of Common Stock, $0.10 par value and 8,000,000 shares of preferred stock, $0.10
par value ("Preferred Stock"). As of September 30, 1997, there were 12,543,343
shares of Common Stock issued and outstanding, and no shares of Preferred Stock
had been issued.
 
     Each outstanding share of Common Stock is entitled to one vote on all
matters submitted to a vote of stockholders, including the election of
directors. The holders of Common Stock do not have cumulative voting rights.
Dividends may be paid to holders of Common Stock when, as and if declared by the
Board of Directors out of funds legally available therefor. Holders of Common
Stock have no conversion, redemption or preemptive rights. All shares of Common
Stock, when validly issued and fully paid, will be non-assessable. In the event
of any liquidation, dissolution or winding up of the Company, holders of Common
Stock are entitled to share ratably in the assets of the Company remaining after
provision for payment of creditors and after the liquidation preference, if any,
of any Preferred Stock outstanding at the time.
 
     The Company is authorized to issue Preferred Stock from time to time, in
one or more series with such rights, preferences, privileges and restrictions,
including dividend rights, voting rights, conversion rights, terms of redemption
and liquidation preferences as may be fixed or designated by the Board of
Directors without any further vote or action by the stockholders. Under certain
circumstances, the issuance of such Preferred Stock may render more difficult or
tend to discourage a merger, tender offer or proxy contest, the assumption of
control by a holder of a large block of the Company's securities or the removal
of incumbent management. The Board of Directors of the Company, without
stockholder approval, may issue Preferred Stock with voting and conversion
rights and dividend and liquidation preferences which could adversely affect the
holders of Common Stock. No shares of Preferred Stock are outstanding, and the
Company currently has no plans to issue any Preferred Stock.
 
     The Company is subject to Section 203 of the Delaware General Corporation
Law ("Section 203") which contains certain restrictions on the ability of an
"interested stockholder" (defined as a stockholder owning 15% or more of a
corporation's voting stock) to engage in a "business combination" with such
corporation. For purposes of Section 203, "business combination" is defined
broadly to include mergers, asset sales and other transactions resulting in a
financial benefit to the interested stockholder. Since the Company has not
amended its Certificate of Incorporation or Bylaws to prohibit the application
of Section 203, such section may inhibit an interested stockholder's ability to
acquire additional shares of Common Stock or otherwise engage in a business
combination with the Company.
 
     The Company's Certificate of Incorporation and Bylaws contain provisions
(i) limiting the personal liability of its directors for monetary damages
resulting from breaches of their duty of care to the extent permitted by Section
102(b)(7) of the Delaware General Corporation Law, and (ii) making
indemnification of the Company's directors and officers mandatory to the fullest
extent permitted by the Delaware General Corporation Law, including
circumstances in which indemnification is otherwise discretionary.
 
     The Board of Directors of the Company is divided into three classes that
are elected for staggered three-year terms. The holders of a majority of the
outstanding voting stock may remove a director with or without cause. The number
of directors to constitute the entire Board of Directors may be determined only
by the Board of Directors. Any new director elected or chosen to fill a vacancy
will serve for the remainder of the full term of the class in which such vacancy
occurred, rather than until the next election of directors. These provisions of
the Company's Certificate of Incorporation further provide that the affirmative
vote of holders of 60% of the Company's outstanding voting stock is required to
amend these provisions as well as related provisions of the Company's Bylaws.
 
     The provisions of the Company's Certificate of Incorporation and Bylaws
summarized in certain of the preceding paragraphs may be deemed to have an
anti-takeover effect and may delay, defer or prevent a tender offer or takeover
attempt that a stockholder might consider in such stockholder's best interest,
including those attempts that might result in a premium over the market price
for the shares held by stockholders.
 
     The Transfer Agent and Registrar for the Company's Common Stock is Chase
Mellon Securities Trust Company.

     Subject to the terms and conditions set forth in a purchase agreement (the
"Purchase Agreement"), the Company has agreed to sell to each of the
Underwriters named below (the "Underwriters"), and each of the Underwriters, for
whom Merrill Lynch, Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and
Raymond James & Associates, Inc. ("Raymond James") are acting as representatives
(the "Representatives"), has severally agreed to purchase from the Company the
number of shares of Common Stock set forth below opposite their respective names
at the public offering price less the underwriting discount set forth on the
cover page of this Prospectus. In the Purchase Agreement, the several

to purchase all of the shares of Common Stock being sold pursuant to the
Purchase Agreement if any of the shares of Common Stock being sold pursuant to
the Purchase Agreement are purchased.

</TABLE>
 
     The Representatives have advised the Company that the Underwriters
initially propose to offer the shares of Common Stock to the public at the
public offering price set forth on the cover page of this Prospectus, and to
certain dealers at such price less a concession not in excess of $          per
share. The Underwriters may allow, and such dealers may reallow, a discount not
in excess of $          per share on sales to certain other dealers. After the
Offering, the public offering price, concession and discount may be changed.
 
     The Company has granted to the Underwriters an option, exercisable for 30
days after the date of the Offering, to purchase up to 450,000 additional shares
of Common Stock solely to cover over-allotments, if any, at the public offering
price set forth on the cover page hereof less the underwriting discount. If the
Underwriters exercise this option, each of the Underwriters will have a firm
commitment, subject to certain conditions, to purchase approximately the same
percentage of the option shares that the number of shares of Common Stock to be
purchased initially by that Underwriter bears to the total number of shares to
be purchased initially by the Underwriters.
 
     The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act of 1933, as amended,
or to contribute to payments the Underwriters may be required to make in respect
thereof.
 
     The Company, each of its directors and each of its executive officers have
agreed not to offer, sell or otherwise dispose of any shares of Common Stock,
without the prior consent of Merrill Lynch, for a period of 120 days from the
date of this Prospectus, except that the Company may, without such consent,
grant options or issue shares of Common Stock upon the exercise of outstanding
options pursuant to the Company's stock option and incentive plans.
 
     Until the distribution of the Common Stock is completed, rules of the
Securities and Exchange Commission may limit the ability of the Underwriters and
certain selling group members to bid for and purchase the Common Stock. As an
exception to these rules, the Representatives are permitted to engage in certain
transactions that stabilize the price of the Common Stock. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of Common Stock.
 
                                       39
<PAGE>   43
 
     If the Underwriters create a short position in the Common Stock in
connection with the Offering, i.e., if they sell more shares of Common Stock
than are set forth on the cover page of the Prospectus, the Representatives may
reduce that short position by purchasing Common Stock in the open market. The
Representatives may also elect to reduce any short position by exercising all or
part of the over-allotment option described above.
 
     The Representatives may also impose a penalty bid on certain Underwriters
and selling group members. This means that if the Representatives purchase
shares of Common Stock in the open market to reduce the Underwriters' short
position or to stabilize the price of the Common Stock, they may reclaim the
amount of the selling concession from the Underwriters and selling group members
who sold those shares as part of the Offering.
 
     In general, purchases of a security for the purpose of stabilization or to
reduce a short position could cause the price of the security to be higher than
it might be in the absence of such purchases. The imposition of a penalty bid
might also have an effect on the price of the Common Stock to the extent that it
discourages resales of the Common Stock.
 
     Neither the Company nor any of the Underwriters makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Stock. In addition, neither
the Company nor any of the Underwriters makes any representation that the
Representatives will engage in such transactions or that such transactions, once
commenced, will not be discontinued without notice.
 
     Merrill Lynch has from time to time provided investment banking and
financing services to the Company, for which it has received customary
compensation, and may continue to do so in the future.
 
     Thomas A. James, who is a member of the Company's board of directors, is
also the Chairman of Raymond James. Because of Mr. James' directorships and
executive positions, the National Association of Securities Dealers, Inc.
("NASD") may view the Offering as a participation by Raymond James, an NASD
member, in the distribution in a public offering of the securities of its
affiliate. As a result, the Offering is being made pursuant to the provisions of
Rule 2720 of the NASD's Conduct Rules. In accordance with such Rule 2720, the
Underwriters will not make sales of Common Stock offered hereby to customers'
discretionary accounts without the prior specific written approval of such
customers.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Haynes and Boone, L.L.P., Houston, Texas. Certain legal
matters will be passed upon for the Underwriters by Skadden, Arps, Slate,
Meagher and Flom LLP, New York, New York.

             PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
                                  (UNAUDITED)
 
     The accompanying unaudited Pro Forma Condensed Consolidated Financial
Statements have been prepared by recording pro forma adjustments to the
historical consolidated financial statements of the Company. The Pro Forma
Consolidated Balance Sheet as of June 30, 1997 has been prepared as if the
Alchem Acquisition and the Offering, were consummated on June 30, 1997. The Pro
Forma Consolidated Statements of Earnings for the year ended December 31, 1996
and for the six months ended June 30, 1997 have been prepared as if the IMSAMET
and Rock Creek acquisitions, the Alchem Acquisition and the Offering had been
consummated on January 1, 1996.
 
     The Pro Forma Condensed Consolidated Statement of Earnings for the year
ended December 31, 1996 has been derived from (i) the historical audited
consolidated financial statements of the Company for the year ended December 31,
1996, included elsewhere in this Prospectus, (ii) the historical audited
consolidated financial statements of IMSAMET, Inc. ("IMSAMET") for the year
ended December 31, 1996, incorporated by reference in this Prospectus, (iii) the
historical unaudited financial statements of Rock Creek Aluminum, Inc. ("Rock
Creek") for the year ended December 31, 1996 and (iv) the audited financial
statements of Alchem Aluminum, Inc. ("Alchem") for its fiscal year ended October
31, 1996.
 
     The Pro Forma Condensed Consolidated Statement of Earnings for the six
months ended June 30, 1997 and the Pro Forma Condensed Consolidated Balance
Sheet at June 30, 1997 have been derived from (i) the historical unaudited
consolidated financial statements of the Company as of and for the six-month
period ended June 30, 1997, included elsewhere in this Prospectus and (ii) the
historical unaudited financial statements of Alchem for the eight month period
ended June 30, 1997.
 
     The Pro Forma Condensed Consolidated Financial Statements are not
necessarily indicative of the financial position or results of operations that
would have occurred had the transactions been effected on the assumed dates.
Additionally, future results may vary significantly from the results reflected
in the Pro Forma Consolidated Statements of Earnings due to normal fluctuations
in operating levels, changes in prices, future transactions and other factors.
These statements should be read in conjunction with the Company's Consolidated
Financial Statements included elsewhere in this Prospectus.

                         PRO FORMA FINANCIAL STATEMENTS
 
A. PRO FORMA ADJUSTMENTS FOR THE IMSAMET ACQUISITION
 
     In January 1997, the Company acquired all of the outstanding common stock
of IMSAMET, a wholly owned subsidiary of EnviroSource, Inc. for approximately
$58,000,000 in cash, not including acquisition costs. The purchase price was
funded through borrowings under the Credit Agreement. The acquisition was
accounted for using the purchase method of accounting. The pro forma adjustments
to the historical statement of earnings to reflect the IMSAMET acquisition as if
it had been consummated on January 1, 1996 are as follows:
 
          A1. To reverse management fees charged to IMSAMET by its former
     parent.
 
          A2. To reflect additional depreciation expense based on the fair value
     of the assets acquired. Pro forma depreciation is computed on a
     straight-line basis over the estimated useful lives of the assets acquired.
 
          A3. To eliminate expenses related to the IMSAMET corporate office,
     which would not have been incurred.
 
          A4. To record the net increase in amortization expense resulting from
     goodwill acquired and from debt issuance costs incurred to obtain the
     Credit Agreement. Goodwill is amortized on a straight-line basis over a 40
     year life, and debt issuance costs are amortized over the seven-year term
     of the Credit Agreement.
 
          A5. To adjust interest expense to (i) eliminate interest expense on
     the existing debt of the Company which was retired ($3,120,000), (ii)
     eliminate interest expense incurred by IMSAMET on debt to its former parent
     ($1,533,000), and (iii) record interest expense on borrowings under the
     Credit Agreement ($7,927,000). Pro forma interest expense on borrowings
     under the Credit Agreement was computed using LIBOR plus 1.5%. An increase
     of .125% in the assumed interest rate would increase pro forma interest
     expense related to the IMSAMET Acquisition by $138,000 for the year ended
     December 31, 1996.
 
          A6. To adjust income tax expense based on the combined effective
     federal and state income tax rates.
 
          A7. To adjust minority interests related to additional depreciation
     expense.
 
B. PRO FORMA ADJUSTMENTS FOR THE ROCK CREEK ACQUISITION
 
     In January 1997, the Company acquired, in a privately negotiated
transaction, all of the outstanding common stock of Rock Creek in exchange for
618,137 shares of the Company's common stock. The acquisition was accounted for
using the purchase method of accounting. The pro forma adjustments to the
historical statement of earnings to reflect the Rock Creek acquisition as if it
had been consummated on January 1, 1996 are as follows:
 
          B1. To eliminate sales and cost of sales for transactions between Rock
     Creek and the Company.
 
          B2. To adjust amortization expense for the goodwill acquired. Goodwill
     is amortized on a straight-line basis over a 40 year life.
 
          B3. To adjust income tax expense based on the combined effective
     federal and state income tax rates.
 
          B4. To reflect the issuance of 618,137 shares of the Company's common
     stock in the transaction.

                 PRO FORMA FINANCIAL STATEMENTS -- (CONTINUED)
 
C. PRO FORMA ADJUSTMENTS FOR THE ALCHEM ACQUISITION
 
     In September 1997, the Company announced that it had entered into a
non-binding letter of intent to acquire, in a privately negotiated transaction,
all of the capital stock of Alchem in exchange for cash and 1,208,339 shares of
common stock. The amount of cash to be paid will be determined by deducting the
aggregate amount of Alchem's obligations for borrowed money outstanding as of
the closing date of the acquisition from $26,250,000. At June 30, 1997, the
amount of Alchem's indebtedness for borrowed money outstanding was $11,348,000.
Assuming that such amount of Alchem indebtedness is outstanding at the closing
date, the total cash to be paid by the Company to Alchem would be $14,902,000.
The cash portion of the acquisition price and the repayment of Alchem's
indebtedness is assumed to be funded by borrowings under the proposed $175
million reducing revolving credit facility ("Revolver"). The acquisition, which
is expected to close in October 1997, will be accounted for using the purchase
method of accounting. The pro forma adjustments to the historical financial
statements for the pending Alchem Acquisition are as follows:
 
          C1. To adjust cost of sales to conform Alchem's accounting policy for
     inventory (LIFO) to a method approximating the Company's accounting policy
     (average cost).
 
          C2. To eliminate the results of Alchem's operations for the two months
     ended December 31, 1996 to conform with the Company's interim accounting
     period.
 
          C3. To eliminate sales and cost of sales for transactions between
     Alchem and the Company and Rock Creek.
 
          C4. To reflect additional depreciation expense based on the fair value
     of the assets acquired. Pro forma depreciation is computed on a
     straight-line basis over the estimated useful lives of the assets acquired.
 
          C5. To adjust amortization expense for the goodwill acquired and
     Alchem's debt issuance costs written-off. Goodwill is amortized on a
     straight-line basis over a 40 year life.
 
          C6. To record the net increase in interest expense due to assumed
     borrowings of $26,250,000 under the Revolver using LIBOR plus 1.5%, less
     interest expense on the Alchem indebtedness retired. An increase of .125%
     in the assumed interest rate would increase pro forma interest expense
     related to the Alchem Acquisition by $32,000 and $16,000 for the year ended
     December 31, 1996 and the six months ended June 30, respectively.
 
          C7. To adjust income tax expense based on the combined effective
     federal and state income tax rates.
 
          C8. To record borrowings of $26,250,000 under the Revolver to fund the
     cash portion of the purchase price and repayment of Alchem's indebtedness.
 
          C9. To reclassify the current portion of borrowings under the Credit
     Agreement to long-term pursuant to the proposed terms of the Revolver.
 
          C10. To record the acquisition of the capital stock of Alchem for
     1,208,339 shares of the Company's common stock and $14,902,000 in cash. The
     shares of common stock to be issued were valued at $19.0344 per share
     (which is the average closing price for the Company's common stock for the
     20 consecutive trading days preceding September 15, 1997, the date of the
     letter of intent), less a 25% discount to reflect the contractual
     restrictions on the resale of such shares. The actual amount of cash to be
     paid will be determined by subtracting Alchem's actual outstanding
     obligations for borrowed money at the date of closing from $26,250,000.

          C11. To record the repayment of the Alchem indebtedness.
 
          C12. To eliminate accounts receivable and accounts payable between
     Alchem and the Company.
 
          C13. To record the accrual of severance pay, deferred income taxes and
     other merger related costs.
 
          C14. To adjust assets and liabilities under the purchase method of
     accounting based on the Company's purchase price. The Company's purchase
     price has been allocated to the consolidated assets and liabilities of
     Alchem based on preliminary estimates of fair values with the remaining
     purchase price allocated to goodwill. The information presented herein may
     differ from the actual purchase price allocation.
 
     The preliminary allocation of the purchase price included in the pro forma
balance sheet is summarized as follows (in thousands):

     recycling plant.
 
D. PRO FORMA ADJUSTMENTS FOR THE OFFERING
 
     The Pro Forma Condensed Consolidated Financial Statement assume the
issuance of 3,000,000 shares of the Company's common stock pursuant to the
Offering at a price of $19.00 per share resulting in net proceeds to the Company
of $53,650,000. The pro forma adjustments to the historical financial statements
for the Offering are as follows:
 
          D1. To reduce interest expense due to the use of the proceeds of the
     Offering to repay long-term debt. See Note D4. Interest expense on the
     remaining outstanding borrowings under the Credit Agreement was computed
     using LIBOR plus .75%. An increase of .125% in the assumed interest rate
     would increase pro forma interest expense by $90,000 and $45,000 for the
     year ended December 31, 1996 and the six months ended June 30, 1997,
     respectively.
 
          D2. To record additional income tax expense based on the reduction in
     interest expense resulting from the repayment of long-term debt.
 
          D3. To record the issuance of 3,000,000 shares of common stock at
     $19.00 per share, less the estimated underwriting discount and transaction
     costs of $3,350,000.
 
          D4. To record the use of proceeds from the Offering to repay long-term
     debt.

                      IMCO RECYCLING INC. AND SUBSIDIARIES
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   (INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
            (DOLLARS IN TABLES ARE IN THOUSANDS, EXCEPT SHARE DATA)
 
NOTE A -- SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Consolidation:
 
     The accompanying consolidated interim financial statements include the
accounts of IMCO Recycling Inc. and all of its subsidiaries (the "Company"). All
significant intercompany accounts and transactions have been eliminated upon
consolidation. Investments in affiliated companies, owned 50% or less, are
recorded by the Company on the equity method.
 
     The Company's principal business involves the owning and operating of
aluminum recycling facilities. The Company recycles scrap material for a fee and
returns the material to its customers, some of whom are the world's largest
aluminum companies. The Company also buys scrap on the open market and recycles
and sells it.
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities, the
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Interim Financial Information:
 
     The accompanying unaudited interim consolidated financial statements have
been prepared in accordance with generally accepted accounting principles for
interim financial information and Article 10 of Regulation S-X. Accordingly,
they do not include all of the information and footnotes required by generally
accepted accounting principles for complete financial statements. In the opinion
of management, all adjustments (consisting of normal recurring accruals)
considered necessary for a fair presentation of the Company's financial position
at June 30, 1997 and the results of its operations and cash flows for the six
months ended June 30, 1996 and 1997 have been included. Operating results for
the six months ended June 30, 1997 are not necessarily indicative of the results
that may be expected for the year ending December 31, 1997.
 
  Cash Equivalents:
 
     The Company considers all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. The carrying amount
approximates fair value because of the short maturity of those instruments.
 
  Inventories:
 
     Inventories are stated at the lower of average cost or market.
 
  Credit Risk:
 
     A majority of the Company's accounts receivable are due from companies in
the aluminum industry. Credit is extended based on evaluation of the customers'
financial condition and, generally, collateral is not required. Credit losses
are within management's expectations and historically have been very low.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
   (INFORMATION FOR THE SIX MONTHS ENDED JUNE 30, 1996 AND 1997 IS UNAUDITED)
            (DOLLARS IN TABLES ARE IN THOUSANDS, EXCEPT SHARE DATA)
 
  Property and Equipment:
 
     Property and equipment are stated at cost. Major renewals and improvements
are capitalized, while maintenance and repairs are expensed when incurred.
Depreciation is computed using the straight-line method over the estimated
useful lives of the related assets.
 
     Landfill closure costs are currently estimated to be in excess of
$4,000,000 and are being accrued as space in the landfills are used. Landfill
costs are depreciated as space in the landfill is used.
 
     The Company reviews its property and equipment for impairment when changes
in circumstances indicate that the carrying amount of an asset may not be
recoverable. Impairment is measured as the amount by which the carrying amount
of the asset exceeds the estimated fair value of the asset less disposal costs.
 
     Interest is capitalized in connection with the construction of major
facilities. Capitalized interest costs for 1994, 1995 and 1996 were $309,000,
$438,000 and $237,000, respectively.
 
  Amortization of Intangibles:
 
     The excess of original acquisition cost over the fair value of net assets
acquired is amortized on a straight-line basis over their expected life,
currently from 7 to 40 years. Management regularly reviews the remaining
goodwill with consideration toward recovery through future operating results.
Goodwill is evaluated by the Company on an undiscounted basis. Deferred debt
issuance costs, included in other assets, are being amortized over the term of
the long-term debt based upon the average amount of debt outstanding. Patents
are amortized over their remaining legal lives.
 
  Net Earnings Per Share:
 
     Earnings per common share are based upon the weighted average number of
common and common equivalent shares outstanding in each period. Common
equivalent shares relate solely to outstanding warrants and stock options.
 
     In February 1997, the Financial Accounting Standards Board issued Statement
of Financial Accounting Standards ("SFAS") No. 128, "Earnings per Share," which
is required to be adopted on December 31, 1997. At that time, the Company will
be required to change the method currently used to compute earnings per share
and to restate all prior periods. Under the new requirements for calculating
primary earnings per share, the dilutive effect of stock options will be
excluded. The effect of SFAS No. 128 on the calculation of earnings per share
for the three years ended December 31, 1996 and the six month periods ended June
30, 1996 and 1997 is not expected to be material.
 
  Stock-Based Compensation:
 
     The Company follows Accounting Principles Board Opinion No. 25, "Accounting
for Stock Issued to Employees" ("APB 25") and related interpretations in
accounting for its employee stock options. Under APB 25, if the exercise price
of employee stock options equals the market price of the underlying stock on the
date of grant, no compensation expense is recorded.
 
  Prior Year Reclassifications:
 
     Certain reclassifications have been made to prior year statements to
conform to the current year presentation.

NOTE B -- ACQUISITIONS AND INVESTMENTS
 
     In September 1994, the Company purchased the stock of Phoenix Smelting
Corporation, which operated an aluminum recycling facility in Loudon, Tennessee,
through its wholly owned subsidiary, Metal Resources, Inc. ("Loudon"). The value
of the transaction, which was accounted for as a purchase, was approximately
$10,000,000, including the Company's repayment of approximately $5,100,000 of
debt and the issuance of 299,882 shares of the Company's common stock.
 
     In September 1995, the Company purchased all of the assets of an aluminum
recycling facility located in Bedford, Indiana from a private aluminum company.
The transaction was accounted for as a purchase for approximately $8,500,000 in
cash.
 
     In October 1995, the Company acquired all of the outstanding stock of
Alumar Associates, Inc., which owned Metal Mark, Inc. Metal Mark, Inc. owned and
operated three aluminum recycling plants located in Chicago Heights, Illinois;
Sikeston, Missouri; and Pittsburg, Kansas and owned 50% of a fourth facility in
East Chicago, Indiana. The value of the transaction, which was accounted for as
a purchase, was approximately $16,745,000, including the assumption of
$8,245,000 of long-term debt of Alumar. The remainder of the purchase price
consisted of $4,000,000 in cash and 208,213 shares of the Company's common
stock.
 
     During 1996, the Company began construction of an aluminum recycling
facility in Coldwater, Michigan through its joint venture, IMCO Recycling of
Michigan L.L.C. The Company is a 75% managing member of the venture, which will
have a long-term supply agreement for the delivery of molten metal to its 25%
member, Alchem Aluminum, Inc. The Company's share of the total cost of the plant
is expected to be approximately $12,000,000, of which approximately $7,200,000
had been expended as of December 31, 1996. The plant commenced operations in
February 1997.
 
     In May 1996, the Company contributed approximately $14,000,000 for a 50%
interest in VAW-IMCO GuSS und Recycling GmbH, a joint venture in Germany. This
joint venture was formed to own and operate two aluminum recycling facilities
previously owned by VAW aluminium AG, an aluminum products manufacturing company
in Germany. The plants primarily serve the European automotive market.
 
     In January 1997, the Company acquired all of the outstanding common stock
of IMSAMET, Inc. ("IMSAMET"), a wholly owned subsidiary of EnviroSource, Inc.,
for approximately $58,000,000 in cash, not including acquisition costs. IMSAMET
operates and owns or has a majority interest in three aluminum recycling plants
located in Post Falls, Idaho; Wendover, Utah and Goodyear, Arizona. In addition,
IMSAMET has a 50% interest in a joint venture facility, adjacent to the Utah
plant, which uses a proprietary process to reclaim materials from salt cake. The
acquisition was accounted for using the purchase method of accounting.
Accordingly, the purchase price was allocated to the net assets acquired based
on their estimated fair values. The estimated excess of the purchase price over
the fair value of net assets acquired is being amortized over forty years on a
straight-line basis.
 
     The preliminary allocation of the purchase price of IMSAMET is as follows:

     Also in January 1997, the Company acquired in a privately-negotiated
transaction all of the outstanding common stock of Rock Creek Aluminum, Inc.
("Rock Creek") in exchange for 618,137 shares of the Company's common stock. The
acquisition was accounted for using the purchase method of accounting. The
estimated excess of the purchase price over the fair value of net assets
acquired was $6,000,000 and is being amortized over forty years on a
straight-line basis. Rock Creek owns and operates two Ohio facilities located in
Elyria and Rock Creek. These facilities utilize milling, blending, testing and
packaging equipment to process various types of raw materials, including
aluminum dross and scrap, various minerals and slags.
 
     The following table sets forth pro forma results of operations of the
combined entities of the Company IMSAMET and Rock Creek for the year ended
December 31, 1996, assuming the acquisitions had been consummated on January 1,
1996. The pro forma combined information is presented for comparative purposes
only and does not purport to represent the actual results which would have
occurred had the acquisition been consummated on such date or of future results
of the combined companies under the ownership and management of the Company:

Industries, Inc. ("Commonwealth"), formerly Barmet Aluminum Corporation, to
construct, own and operate the Uhrichsville plant adjacent to Commonwealth's
rolling mill in Uhrichsville, Ohio and to supply Commonwealth with all of its
recycled aluminum needs. The Uhrichsville plant, including costs for capitalized
interest and for the 1994 expansion, cost approximately $20,750,000.
Commonwealth has an option to acquire up to a 49% equity interest in the
Company's subsidiary that owns the Uhrichsville plant.

     At December 31, 1996, the Company had a $556,000 valuation allowance to
reduce certain deferred tax assets to amounts that are more likely to be
realized. The allowance includes $237,000 net operating loss assets generated by
the Loudon facility prior to its acquisition by the Company. The majority of the
remaining $319,000 relates to the Company's ability to utilize state investment
tax credits generated by the Company's Corona, California facility, which was
closed in 1996.
 
     At December 31, 1996, the Company had $1,470,000 of unused income tax
credit carryforwards, $168,000 of which expire in 1998, $96,000 of which expire
in 2010, and $1,206,000 of which do not expire. The

     In 1995, the Company increased its short-term working capital line of
credit borrowing limit to $10,000,000 under a restated revolving credit facility
(the "Revolving Facility"). On May 31, 1996, the Company further increased its
limit to $12,000,000. Under the Revolving Facility, the Company had a
subfacility for the issuance of standby letters of credit. To meet working
capital needs, on December 30, 1996, the Company borrowed $2,000,000 under this
Revolving Facility at an interest rate of 8.25%.
 
     The 7.65% Morgantown, Kentucky Solid Waste Disposal Facilities Revenue
Bonds (Series 1996) are due on May 1, 2016. The bonds were issued in 1996 in
conjunction with the Company's construction of its salt cake processing plant in
Morgantown, Kentucky. The bonds were issued at a 1% discount, which is being
amortized over the life of the bonds.
 
     The 7.45% Morgantown, Kentucky Solid Waste Disposal Facilities Revenue
Bonds (Series 1997) are due on May 1, 2022. The bonds were issued in April 1997
in connection with the Company's expansion of its landfill in Morgantown and
additional construction costs of its salt cake processing facility in
Morgantown.
 
     The Variable Rate Term Loan and the Variable Rate Converting Revolving Loan
had fluctuating interest rates based on the Company's ratio of total debt to
earnings before interest, tax, depreciation and amortization. The interest rate
on the Variable Rate Term Loan was 6.8125% and 6.75% at December 31, 1995 and
1996,

respectively. The interest rate on the Variable Rate Converting Revolving Loan
was 6.875% and 6.75% at December 31, 1995 and 1996, respectively.
 
     In connection with the January 1997 acquisitions (Note B), the Company
entered into a new $125,000,000 credit agreement ("Credit Agreement") with
certain lenders, including Merrill Lynch & Co. (as syndication agent) and Texas
Commerce Bank National Association (as administrative agent). The Company
received $110,000,000 at the closing and used approximately $61,000,000 for
acquisitions. The remaining $49,000,000 of the proceeds was used to repay all of
the MONY Senior Notes, the Variable Rate Term Loan, the Variable Rate Converting
Revolving Loan and $2,000,000 in borrowings outstanding under the Revolving
Facility. The early debt retirement generated a loss of $1,318,000 (net of
income taxes), which is reported as an extraordinary item in the six months
ended June 30, 1997.
 
     The Credit Agreement provides for $125,000,000 of senior secured credit
facilities consisting of a $105,000,000 term loan ("1997 Variable Rate Term
Loan"), with a final maturity of seven years, and a $20,000,000 revolving credit
agreement ("1997 Variable Rate Revolving Loan"), with a final maturity of five
years. Of the $20,000,000 revolving credit agreement, $4,000,000 is to be used,
as needed, by the Company for standby letters of credit. Borrowings under the
credit facilities bear a fluctuating interest rate based on LIBOR or the prime
rate, plus a credit margin that is based on the Company's rate of total debt to
earnings before interest, taxes, depreciation and amortization.
 
     In order to reduce the floating interest rate exposure on the 1997 Variable
Rate Term Loan, the Company entered into an interest rate cap transaction ("Rate
Cap Transaction") agreement with Texas Commerce Bank on April 7, 1997. Under the
terms of the Rate Cap Transaction agreement, the floating interest rate for 40%
of the term loan borrowings under the Credit Agreement is capped at 8% per
annum. The costs associated with the Rate Cap Transaction will be amortized as
interest expense over the four year term of the agreement.
 
     The Credit Agreement imposes certain restrictions, including: (i) a
prohibition of certain other indebtedness, (ii) maintenance of certain financial
ratios, and (iii) limitations on investments, dividends, and capital
expenditures. The annual limitations on cash dividends are as follows:
$3,500,000 for 1997 and 1998, $4,000,000 for 1999 and 2000 and $6,000,000 per
year, after the year 2000. The Credit Agreement is secured by substantially all
of the Company's assets, as well as a pledge of the capital stock of
substantially all of the Company's subsidiaries.
 
     At June 30, 1997, the Company had standby letters of credit outstanding
with Texas Commerce Bank National Association and American National Bank and
Trust Company in the amounts of $1,752,000 and $1,044,000, respectively.
 
     Scheduled maturities of long-term debt subsequent to June 30, 1997 are as

NOTE G -- EMPLOYEE BENEFIT PLANS
 
     The Company has a profit-sharing retirement plan covering most of its
employees who meet defined service requirements. Contributions are determined
annually by the Board of Directors and may be as much as 15% of covered
salaries. Contributions for 1994, 1995 and 1996 were $1,039,000, $1,331,000 and
$1,366,000, respectively.
 
     In July 1996, the Company amended and restated the profit-sharing
retirement plan to allow elective contributions as described in the Internal
Revenue Code Section 401(k). Subject to certain dollar limits, employees may
contribute a percentage of their salaries to this plan, and the Company will
match a portion of the employees' contributions. The Company's match of employee
contributions totaled $189,000 for 1996.
 
NOTE H -- STOCK OPTION PLANS
 
     In 1990, the Company adopted an amended and restated stock option plan.
This plan provides for the granting of nonqualified and incentive stock options.
The number of shares of common stock authorized for issuance under the plan is
1,200,000 shares. Options granted under the plan have various vesting periods
and are exercisable for a period of 10 years from the date of grant, although
options may expire earlier because of termination of employment.
 
     In 1992, the Company adopted the 1992 Stock Option Plan, which provides for
the granting of nonqualified and incentive stock options to employees, officers,
consultants and nonemployee members of the Board of Directors. Options granted
to employees under this plan have various vesting periods. Annually, nonemployee
directors will be granted nonqualified stock options exercisable after six
months from the date of grant, equal to that number of shares determined by
dividing the annual director fee amount by the fair market value of a share of
common stock as of the date of grant. All options granted under this plan, once
vested, are exercisable for a period of up to 10 years from the date of grant,
although options may expire earlier because of termination of employment or
service.
 
     In 1996, the Company adopted the Annual Incentive Program, which provides
certain of the Company's key employees with annual incentive compensation tied
to the achievement of pre-established and objective performance goals. This plan
provides for the granting of stock options to key management employees, pursuant
to the plan formula, in the event that the Company's return on total assets (as
defined in the plan) for any bonus year exceeds 15%. Nonqualified and incentive
stock options may be granted, and the terms of the plan concerning the stock
options are substantially the same as the corresponding terms of the 1992 Stock
Option Plan.
 
     The 1992 Stock Option Plan and the 1996 Annual Incentive Program allow for
the payment of all or a portion of the exercise price and tax withholding
obligations in shares of the Company's common stock delivered and/or withheld.
Such payment or withholding will be valued at fair market value as of the date
of exercise. Participants making use of this feature will automatically be
granted a reload stock option to purchase a number of shares equal to the number
of shares delivered and/or withheld. When a reload stock option is granted, a
portion of the shares issued to the participant will be designated as restricted
stock for a period of five years, although the restriction may be removed
earlier under certain circumstances. Reload stock options have an exercise price
equal to the fair market value as of the date of exercise of the original
options and will expire on the same date as the original options.

     Statement of Financial Accounting Standards (SFAS) No. 123, "Accounting for
Stock-Based Compensation" requires disclosure of pro forma net earnings and net
earnings per common share information computed as if the Company had accounted
for its employee stock options granted subsequent to December 31, 1995 under the
fair value method set forth in SFAS No. 123. The fair value of the Company's
outstanding stock options was estimated at the date of grant using a
Black-Scholes option pricing model with the following weighted average
assumptions:

     The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable. In addition, option valuation models require the
input of highly subjective assumptions including the expected stock price
volatility. Because the Company's employee stock options have characteristics
significantly different from those of traded options, and because changes in the
subjective input assumptions can materially affect the fair value estimate, in
management's opinion, the existing models do not necessarily provide a reliable
single measure of the fair value of its employee stock options. For purposes of
pro forma disclosures, the estimated fair value of the options is amortized to
expense over the option's vesting period. In addition, because SFAS No. 123 is
applicable only to options granted subsequent to December 31, 1994, the pro
forma information does not reflect the pro forma effect of all previous stock
option grants of the Company. Therefore, the pro forma information is not
necessarily indicative of future amounts until SFAS No. 123 is applied to all
outstanding stock options.
 
     The Company's pro forma information is as follows:

NOTE I -- OPERATIONS
 
     During 1994, 1995 and 1996, sales to Aluminum Company of America ("Alcoa")
totaled 30%, 23% and 13%, respectively, of revenues. Sales to Commonwealth
totaled 12% of revenues in 1994. No other customer accounted for more than 10%
of revenues in 1994, 1995 and 1996. The loss of Alcoa or Commonwealth would have
a material adverse effect upon the business of the Company and its future
operating result. However, a significant portion of the processing for these
customers is performed pursuant to long-term agreements.
 
     During the third quarter of 1996, the Company recorded a charge to cost of
sales of $3,577,000 resulting from management's decision to close the Company's
Corona, California aluminum recycling plant.
 
     On May 8, 1997, Harvard Industries, Inc. ("Harvard") announced that it had
filed for protection under Chapter 11 of the U.S. Bankruptcy Code. The Company
sells aluminum to Doehler-Jarvis, Inc. ("Doehler-Jarvis"), a subsidiary of
Harvard. At June 30, 1997, the Company had $3,530,000 of outstanding unsecured
receivables from Doehler-Jarvis, net of related reserves. Harvard has previously
indicated that it intends to pay 100% of all pre-petition claims by vendors.
While the Company currently believes that Harvard's bankruptcy will not have a
material adverse effect on the Company's financial position or results of
operations, no assurance can be given as to the amount and timing of the
Company's ultimate recovery of its claims. The Company's revenues from
Doehler-Jarvis totaled $17,490,000 and $12,955,000 for the year ended December
31, 1996 and the six months ended June 30, 1997, respectively. The Company
believes that the loss of this customer will not have a material adverse effect
on the Company's financial position or results of operations.
 
     The Company's operations, like those of other basic industries are subject
to federal, state, local and foreign laws, regulations and ordinances that (i)
govern activities or operations that may have adverse environmental effects,
such as discharges to air and water, as well as handling and disposal practices
for solid and hazardous wastes and (ii) improve liability for the costs of
cleaning up, and certain damages resulting from, past spills, disposals, or
other releases of hazardous substances (together, "Environmental Laws"). It

can be anticipated that more rigorous laws and regulations will be enacted that
could require the Company to make substantial expenditures in addition to those
referred to herein.
 
     From time to time, operations of the Company have resulted or may result in
certain noncompliance with applicable requirements under Environmental Laws.
However, the Company believes that any such noncompliance under current
Environmental Laws would not have a material adverse effect on the Company's
financial position.
 
     The Illinois Environmental Protection Agency ("IEPA") recently notified IZI
that it may be a potentially responsible party ("PRP") pursuant to the Illinois
Environmental Protection Act for the cleanup of contamination at a site in
Marion County, Illinois to which IZI, among others, sent zinc oxides for
processing and resale in the past. IZI has joined a group of PRPs which is
planning to negotiate with the IEPA regarding the cleanup of the site. Although
the site has not been fully investigated and final cleanup costs have not yet
been determined, based on current cost estimates and information regarding the
amount and type of materials sent to the site by IZI, the Company does not
believe, although there can be no assurance, that its liability at this site
will have a material adverse effect on its financial position.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     The Company has authority under Article 145 of the General Corporation Law
of the State of Delaware to indemnify its officers, directors, employees and
agents to the extent provided in such statute. Article Eighth of the Company's
Certificate of Incorporation and Article VI of the Company's Bylaws provide for
indemnification of the Company's officers, directors, employees and agents.
 
     Article 102 of the General Corporation Law of the State of Delaware and
Article Eighth of the Company's Certificate of Incorporation permit the
limitation of directors' personal liability to the corporation or its
stockholders for monetary damages for breach of fiduciary duties as a director
except in certain situations including the breach of a director's duty of
loyalty or acts or omissions not made in good faith.
 
     Reference is also made to the indemnification provisions of Section 6 of
the Purchase Agreement filed as Exhibit 1.1 hereto under which the Underwriters
have agreed to indemnify the Company, its directors and officers and certain
other persons against certain liabilities, including liabilities under the
Securities Act of 1933, with respect to information furnished in writing to the

ITEM 17. UNDERTAKINGS.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer, or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
     The undersigned registrant hereby undertakes that (1) for purposes of
determining any liability under the Act, the information omitted from the form
of prospectus filed as part of this registration statement in reliance upon Rule
430A and contained in a form of prospectus filed by the registrant pursuant to
Rule 424(b)(1) or (4) or 497(h) under the Act shall be deemed to be part of this
registration statement as of the time it was declared effective; and (2) for the
purpose of determining any liability under the Act, each post-effective
amendment that contains a form of prospectus shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.
 
     The undersigned registrant hereby undertakes that, for purposes of
determining any liability under the Act, each filing of the registrant's annual
report pursuant to section 13(a) or section 15(d) of the Securities and Exchange
Act of 1934 (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Securities Exchange Act of 1934)
that is incorporated by reference in the registration statement shall be deemed
to be a new registration statement relating to the securities offered therein,
and the offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.

Re: Public Offering of Common Stock
 
Gentlemen:
 
     As securities counsel for IMCO Recycling Inc., a Delaware corporation (the
"Company"), we have examined the Company's Certificate of Incorporation and
By-Laws, each as amended, and such other corporate records, documents and
proceedings, and such questions of law, as we have deemed relevant for the
purpose of this opinion, together with the Company's Registration Statement (the
"Registration Statement") on Form S-3, as filed with the Securities and Exchange
Commission covering, among other things, the registration under the Securities
Act of 1933, as amended, of 3,450,000 shares (collectively, the "Shares") of the
Company's Common Stock.
 
     On the basis of such examination, we are of the opinion that the Shares
have been duly authorized and, subject to payment therefor as described in the
Registration Statement, the Shares will be duly and validly issued and fully
paid and nonassessable.
 
     We hereby consent to the use of our name in the Registration Statement and
the related prospectus contained therein, and we also consent to the filing of
this opinion as an exhibit to the Registration Statement.
 
Very truly yours,
 
  /s/ HAYNES AND BOONE, L.L.P.
