                                    PART I

ITEM 1.   BUSINESS

     (a)  GENERAL DEVELOPMENT OF BUSINESS

     BACKGROUND OF COMPANY

     Tower Automotive, Inc. and its Subsidiaries (collectively referred to as
the "Company") is a leading designer and producer of high-quality body structure
components and assemblies used by the major North American automotive original
equipment manufacturers ("OEMs"), Ford, Chrysler and General Motors, and certain
foreign OEMs with manufacturing operations in North America ("Transplants"),
including Honda, Toyota, Nissan and Mazda.  The Company's current products range
from large structural stampings and assemblies, such as body pillars, chassis,
suspension and floor pan components and major housing assemblies, to engineered
mechanical parts, such as hood and deck lid hinges and brake components.  Since
its inception in April 1993, the Company's revenues have grown rapidly through a
focused strategy of internal growth and a highly disciplined acquisition
program.  During the last three years, the Company has successfully completed
and fully integrated four acquisitions.  As a result of such acquisitions and
internal growth, revenues have increased from approximately $86 million in 1993
to approximately $400 million in 1996, representing a compound annual growth
rate of approximately 71%.  The Company's North American content per vehicle has
increased from $6.23 in 1993 to $26.74 in 1996.

     The Company operates in the large and highly fragmented structural 
segment of the automotive supply industry, which has recently begun to 
undergo significant consolidation.  To lower costs and improve quality, OEMs 
are reducing their supplier base by awarding sole-source contracts to 
full-service suppliers who are able to supply larger portions of a vehicle on 
a global basis. OEM's criteria for supplier selection include not only cost, 
quality and responsiveness, but also full-service design, engineering and 
program management capabilities.  OEMs are increasingly seeking suppliers 
capable of providing complete systems or modules rather than suppliers who 
only provide separate component parts.  In addition, OEMs are increasingly 
requiring their suppliers to have the capability to design and manufacture 
their products in multiple geographic markets.  As a full-service supplier 
with strong OEM relationships, the Company expects to continue to benefit 
from these trends within the structural segment of the automotive supply 
industry.

     The Company was formed to acquire R.J. Tower Corporation (the 
"Predecessor" or "R.J. Tower"), the acquisition of which was completed in 
April 1993 for an aggregate cost of approximately $26 million.  Since April 
1993, the Company has successfully completed or announced five strategic 
acquisitions including:

     MSTI. In May 1996, the Company acquired MascoTech Stamping Technologies, 
Inc. ("MSTI") from MascoTech, Inc. ("MascoTech") for approximately $79 
million (including the payment of related fees and expenses), plus additional 
earn-out payments if certain operating targets are achieved by the MSTI 
facilities in the first three years following the acquisition.  The MSTI 
acquisition:  (i) expanded the Company's product capabilities into chassis 
and suspension components; (ii) provided chassis and suspension technology as 
well as value-added processing technologies including assembling, painting 
and welding; and (iii) increased the Company's content per vehicle on key 
light truck and sport utility vehicles such as the Ford F-Series, 

                                     -2-

<PAGE>

Explorer and Windstar and the Chrysler Ram and Dakota as well as on high 
volume passenger cars such as the Ford Taurus/Sable.

     TRYLON. In January 1996, the Company acquired Trylon Corporation 
("Trylon") from MascoTech for approximately $25 million in cash, including 
transaction costs.  The Trylon acquisition:  (i) broadened the Company's 
product offerings to include small, precision metal stampings and assemblies, 
which were previously outsourced to third parties; (ii) established a 
relationship between the Company and General Motors; and (iii) increased 
content on Ford models, primarily the Villager.

     KALAMAZOO. In June 1994, the Company acquired Kalamazoo Stamping and Die
Company ("Kalamazoo"), a supplier of structural stampings and assemblies, for
approximately $12 million in cash.  The acquisition of Kalamazoo added
additional structural components to the Company's product offerings and
increased model penetration with Ford.

     EDGEWOOD. In May 1994, the Company acquired Edgewood Tool and 
Manufacturing Company and its affiliate, Ann Arbor Assembly Corporation 
(collectively, "Edgewood") for approximately $30 million in aggregate 
consideration.  Edgewood is a leading supplier of hood and deck lid hinges as 
well as structural stampings and assemblies.  The acquisition of Edgewood:  
(i) added engineered mechanical stampings, primarily hood and deck lid 
hinges, and additional structural components to the Company's product 
offerings; (ii) increased model penetration with the Company's existing 
customers; and (iii) provided the Company with a significant new customer, 
Mazda.

     AUTOMOTIVE PRODUCTS COMPANY. On January 27, 1997, the Company entered 
into an agreement to acquire and assume substantially all of the assets and 
liabilities of the Automotive Products Company (APC), a division of A.O. 
Smith Corporation, for $625 million in cash, subject to certain adjustments.  
APC, which had revenues of approximately $860 million for the year ended 
December 31, 1996, designs and manufactures frames, frame components, engine 
cradles, suspension components and modules for the North American automotive 
and heavy truck industries.  This acquisition is expected to close during the 
second quarter of 1997.

     In connection with this acquisition, the Company agreed to enter into a 
new credit facility with a bank which will provide a total financing 
availability of up to $865 million.  The specific terms and conditions of 
this new credit facility are currently being negotiated with the bank  The 
new credit facility will also include certain restrictive covenants, which 
the Company expects will be similar in nature to those in its existing credit 
agreement.  This facility will become effective contemporaneously with the 
completion of the acquisition discussed above.

     On February 18, 1997, the Company filed a registration statement on Form 
S-3 with the Securities and Exchange Commission related to the proposed sale 
of up to 8,500,000 shares of the Company's Common Stock by the Company to the 
public.  The Company expects this offering will be completed early in the 
second quarter of 1997.  Proceeds from this offering will be used to fund a 
portion of the purchase price related to the acquisition discussed above.

     The Company completed an initial public offering (the "IPO") of its 
Common Stock in August 1994 and the sale of an additional 2,232,900 shares in 
June 1996.  The Company's principal executive offices are located at 4508 IDS 
Center, Minneapolis, Minnesota 55402, and its telephone number is (612) 
342-2310.

     BUSINESS STRATEGY

     The Company's business objective is to capitalize upon the 
consolidation, globalization and system/modular sourcing trends in the 
automotive supply industry in order to enhance its position to be the leading 
provider of structural and suspension components to OEMs on a worldwide 
basis.  Key elements of the Company's operating and growth strategies are 
outlined below:

     OPERATING STRATEGY:

     FULL-SERVICE TECHNICAL DESIGN, ENGINEERING AND PROGRAM MANAGEMENT 
CAPABILITIES.  The Company strives to maintain a competitive advantage 
through investment in research and product development, advanced engineering 
and program management.  The Company works with OEMs throughout the product 
development process from concept vehicle and prototype development through 
the design and implementation of manufacturing processes to provide 
full-service capabilities to its customers.  In some cases, the Company 
places design engineers at customer facilities to coordinate its product 
design efforts with those of its OEM customers.

     EFFICIENT MANUFACTURING/CONTINUOUS IMPROVEMENT PROGRAMS.  In response to 
OEMs' increasingly stringent demands, the Company has implemented 
manufacturing practices designed to maximize product quality and timeliness 
of delivery and eliminate waste and inefficiency.  The Company has continued 
to upgrade its manufacturing equipment and processes through substantial 
investment in new equipment, maintenance of existing equipment and 
utilization of manufacturing engineering personnel.

     GLOBAL PRESENCE.  The Company strives to offer manufacturing and support 
services to its customers on a global basis through a combination of 
international wholly owned facilities and by entering into joint ventures and 
partnerships with foreign suppliers.  Since 1993, in furtherance of its 
global expansion strategy, the Company has opened a European sales and 
engineering office to service U.K. and German OEM customers and has 
established an industrial partnership with The Kirchhoff Group ("Kirchhoff") 
in Germany.  The Company also has relocated certain technical personnel 
resources to locations where OEMs are developing "world cars."

     DECENTRALIZED, PARTICIPATIVE CULTURE.  The Company's decentralized 
approach to managing its manufacturing facilities encourages decision making 
and employee participation in areas such as manufacturing processes and 
customer service. The Company's management team meets frequently at various 
Company locations in order to maintain a unified Company culture.  To 
increase employee productivity, the Company utilizes incentive programs for 
all salaried and hourly employees and provides incentives for employees who 
take advantage of its continuous improvement programs and who provide cost 
savings ideas.

     GROWTH STRATEGY:

     STRATEGIC ACQUISITIONS.  The Company continues to believe that 
consolidation in the automotive supply industry will provide further 
attractive opportunities to acquire high-quality companies that complement 
its existing business.  The Company seeks to make acquisitions that (i) 
provide additional product, manufacturing and technical capabilities; (ii) 
broaden the Company's geographic coverage domestically and strengthen its 
ability to supply products on a global basis; (iii) increase the number of 
models for which the Company supplies products and the content supplied for 
existing models; and (iv) add new customers.  The Company intends to 

                                     -4-

<PAGE>

seek future acquisitions or develop strategic alliances that will strengthen 
the Company's ability to supply its products on a global basis.

     MODULAR PRODUCT OPPORTUNITIES.  The Company has capitalized on the 
system/modular sourcing trend among OEMs by offering customers higher 
value-added supply capabilities through an increasing focus on the production 
of assemblies consisting of multiple component parts that are welded or 
otherwise fastened together by the Company.  The Company has the ability to 
supply OEMs with modules consisting of integrated assemblies and component 
parts that can be installed as a unit in a vehicle at the OEM assembly plant.

     INCREASE VEHICLE PENETRATION.  The Company has developed strong 
relationships with certain OEM engineering and purchasing personnel which 
allow it to identify business opportunities and to react to customer needs in 
the early stages of vehicle design.  The Company believes that these 
relationships give it a competitive advantage over smaller and less capable 
suppliers in marketing its broad range of products and in developing new 
product concepts, such as expanded use of modules, that complement its 
existing product lines.

     PURSUIT OF "WORLD CAR" OPPORTUNITIES.  The Company has been working 
closely with certain customers on the development of "world cars," which are 
designed by OEMs in one vehicle center to a single global standard but 
produced and sold in different geographic markets.  Suppliers for a specific 
"world car" are often required to provide their products on a worldwide 
basis.  The Company believes that it has a competitive advantage in 
potentially supplying certain world cars given its international presence, 
full-service capabilities and existing position as a leading supplier on the 
Ford Escort and DEW98 luxury car, as well as on other existing vehicle 
platforms which may eventually evolve into world cars.

     PRODUCTS

     The Company's current products consist of a broad array of stamped, 
formed, welded and assembled metal components, many of which are critical to 
the structural integrity of a vehicle.  These stampings and assemblies are 
attached directly to the frame of an automobile at the OEM assembly plant and 
comprise the major structure of a vehicle.  Engineered assemblies 
manufactured by the Company, such as hood and deck lid hinges, are attached 
to larger structural components.  These parts use various grades and 
thicknesses of steel including hot and cold rolled, galvanized, organically 
coated, stainless and aluminized steel.  The Company does not produce exposed 
sheet metal components, such as exterior body panels.

     Although a portion of the Company's products are sold directly to OEMs 
as finished products, most are used by the Company to produce assemblies 
consisting of multiple parts that are welded or otherwise fastened together 
by the Company. Systems and assemblies currently produced by the Company 
include front and rear structural suspension systems comprised of control 
arms, suspension links and axle assemblies consisting of stamped metal 
trailing axles, assembled brake shoes, hoses and tie rods.

     CUSTOMERS AND MARKETING

     The North American automotive market is dominated by General Motors, 
Ford and Chrysler, with Transplants representing approximately 20% of this 
market in 1996.  The Company currently supplies its products primarily to 
Ford, Chrysler, Honda, General Motors, Toyota, Nissan and Mazda.

                                     -5-

<PAGE>

     OEMs typically award contracts that cover parts to be supplied for a 
particular car model.  Such contracts range from one year to over the life of 
the model, which is generally three to seven years and do not require the 
purchase by the customer of any minimum number of parts.  The Company 
supplies parts for a broad cross-section of both new and mature models, 
thereby reducing its reliance on any particular model.  For example, the 
Company supplies parts for substantially all models produced by Ford, Honda 
and Chrysler.  The following table presents an overview of the major models 
for which the Company supplies products:

</TABLE>

     Most of the parts the Company produces have a lead time of two to five 
years from product development to production.  See "Design and Engineering 
Support."  Since 1988, the Company has been the leading supplier for hood and 
deck hinges at Ford and Chrysler and is responsible for the design and 
production of such products.  The selling prices of these products are 
generally negotiated between the Company and its customers and are typically 
not subject to a competitive bid process.

     Sales of the Company's products to OEMs are made directly by the 
Company's sales and engineering force, headquartered at the technical center 
located in Farmington Hills, Michigan.  Through the technical center, the 
Company services its OEM customers and manages its continuing programs of 
product design improvement and development.  The Company's sales and 
engineering force consists of approximately 150 individuals, some of whom are 
periodically placed at various customer facilities to facilitate the 
development of new programs.

     DESIGN AND ENGINEERING SUPPORT

     The Company strives to maintain a technological advantage through 
investment in product development and advanced engineering capabilities.  The 
Company's manufacturing engineering capabilities enable it to design and 
build high-quality and efficient manufacturing systems, processes and 
equipment and to continually improve its production processes and equipment.  
The Company's manufacturing engineers are located at each of its 
manufacturing facilities. The Company's engineering staff currently consists 
of approximately 140 full-time engineers, whose responsibilities range from 
research and development, advanced product development, product design, 
testing and initial prototype development to the design and implementation of 
manufacturing processes.

     Because assembled parts must be designed at an early stage in the 
development of new vehicles or model revisions, the Company is increasingly 
given the opportunity to utilize its product engineering resources early in 
the planning process.  Advanced development engineering 

                                     -6-

<PAGE>

resources create original engineering designs, computer-aided designs, 
feasibility studies, working prototypes and testing programs to meet customer 
specifications.  The Company's advanced development capabilities have 
resulted in several innovations in hinge design that have provided 
significant benefits to the Company's customers.  The Company also has full 
service design capability for chassis components.

     GLOBAL INITIATIVES

     The Company has formed, or is in the process of forming, strategic 
alliances with other suppliers throughout the world, including in Europe, 
Asia and Latin America.  The Company has recently opened a European sales and 
engineering office to service its U.K. and German OEM customers.  In 
addition, the Company has a joint manufacturing and marketing agreement with 
Kirchhoff, a German automobile parts supplier, pursuant to which the Company 
and Kirchhoff have agreed to provide manufacturing and marketing services to 
each other when and as required by each company's OEM customers.  A current 
focus of the Company's acquisition strategy is to acquire European suppliers, 
which would provide the Company with a manufacturing presence in Europe and 
afford the Company access to new customer opportunities.

     COMPETITION

     The Company operates in a highly competitive, fragmented market segment 
of the automotive supply industry, with a limited number of competitors 
generating revenues in excess of $200 million.  The number of the Company's 
competitors has decreased in recent years and is expected to continue to 
decrease due to the supplier consolidation resulting from changing OEM 
policies.  The Company's largest competitors include The Budd Company, a 
subsidiary of Thyssen AG ("Budd"), Magna International, Inc. ("Magna"), 
Midway Products Corp., Modern Tool & Die Co., L&W Engineering and divisions 
of OEMs with internal stamping and assembly operations, all of which have 
substantial financial resources.  The Company competes with Magna across most 
of the Company's product lines, and with its other significant competitors in 
various segments of its product lines.  For example, the Company competes 
with Budd for large stampings, while it competes with ITT Automotive for 
hinge business.  Aetna Industries, Active Tool & Die Co., AG Simpson, 
Lobdell-Emory Mfg. Co. and L&W Engineering compete with the Company for 
medium-size structural stampings.

     The Company principally competes for new business both at the beginning 
of the development of new models and upon the redesign of existing models.  
New model development generally begins two to five years before the marketing 
of such models to the public.  Once a producer has been designated to supply 
parts for a new program, an OEM usually will continue to purchase those parts 
from the designated producer for the life of the program, although not 
necessarily for a redesign.  Competitive factors in the market for the 
Company's products include product quality and reliability, cost and timely 
delivery, technical expertise and development capability, new product 
innovation and customer service.

     SUPPLIERS AND RAW MATERIALS

     The primary raw material used to produce the majority of the Company's 
products is steel.  The Company purchases hot and cold rolled, galvanized, 
organically coated, stainless and aluminized steel from a variety of 
suppliers. The Company employs just-in-time manufacturing and sourcing 
systems enabling it to meet customer requirements for faster deliveries while 
minimizing its need to carry significant inventory levels.  The Company has 
not experienced any significant shortages of raw materials and normally does 
not carry inventories of raw materials 

                                     -7-

<PAGE>

or finished products in excess of those reasonably required to meet 
production and shipping schedules.  Raw material costs represented 
approximately 53% of the Company's revenues in 1996 and steel represented 
approximately 70% to 75% of raw material costs in 1996.

     Honda and Chrysler purchase all of the steel used by the Company for 
their models directly from steel producers.  In addition, Ford is in the 
process of implementing a similar program.  As a result, the Company will 
have minimal exposure to changes in steel prices for parts supplied to Ford, 
Honda and Chrysler, which collectively represented 86% of the Company's 
revenues in 1996.

     The Company expects that the content level of metal in cars and light 
trucks will remain constant or increase slightly due to the trend toward 
increased vehicle size and a greater emphasis on metal recycling.  Although 
the search for improved fuel economy and weight reduction has resulted in 
attempts to reduce the sheet metal content of light vehicles, an efficient, 
cost-effective substitute for steel used in the Company's products has not 
been found.  While various polymers have been used recently for fenders, 
hoods and decks, such products do not have the inherent strength or 
structural integrity on a cost-effective basis to be used for structural 
components.  The Company is involved in ongoing evaluations of the potential 
for the use of aluminum and of specialty steel in its products.

     Other raw materials purchased by the Company include dies, fasteners, 
tubing, springs, rivets and rubber products, all of which are available from 
numerous sources.

     EMPLOYEES

     As of December 31, 1996, the Company had approximately 2,900 employees, 
of whom approximately 1,100 are covered under collective bargaining 
agreements, one of which expires in July 1997.  The Company currently 
anticipates that it will enter into a new collective bargaining agreement 
prior to the expiration of such agreement. The remaining collective 
bargaining agreements expire in 1999.  The Company believes that its future 
success will depend in part on its ability to continue to recruit, retain and 
motivate qualified personnel at all levels of the Company.  The Company has 
instituted a large number of employee programs to increase employee morale 
and expand the employees' participation in the Company's business.  The 
Company has not experienced any work stoppages and considers its relations 
with its employees to be good.

to differ materially from those that might be anticipated based on some of 
the statements made in this report.  Investors are cautioned that all 
forward-looking statements involve risks and uncertainty.  Among the factors 
that could cause actual results to differ materially are the following:

    -  RELIANCE ON MAJOR CUSTOMERS AND SELECTED MODELS.  The Company's two 
largest customers, Ford and Chrysler, represented approximately 67% and 10%, 
respectively, of the Company's 1996 revenues.  The loss of Ford, Chrysler or 
any of the Company's other significant customers or a significant decrease in 
demand for certain key models or a group of related models sold by any of 
their major customers could have a material adverse effect on the Company. 

                                     -8-

    -  INDUSTRY CYCLICALITY AND SEASONALITY.  The automotive market is highly 
cyclical and is dependent on consumer spending.  Economic factors adversely 
affecting automotive production and consumer spending could adversely impact 
the Company. 

    -  FAILURE TO OBTAIN BUSINESS RELATED TO NEW AND REDESIGNED MODEL 
INTRODUCTIONS. The failure of the Company to obtain new business on new 
models or to retain or increase business on redesigned existing models could 
adversely affect the Company.

     Management believes that substantially all of its property and equipment 
is in good condition.  In order to increase efficiency, the Company expects 
to make capital expenditures for equipment upgrades at the facilities 
recently acquired in the MSTI acquisition.

     The Company believes that its existing facilities will be adequate to 
meet its production demands for the foreseeable future.  The Company's 
facilities were specifically designed for the manufacturing of the Company's 
products.  The utilization and capacity of such facilities are dependent upon 
the mix of products being produced by the Company.

ITEM 3.   LEGAL PROCEEDINGS

     ENVIRONMENTAL MATTERS

     The Company believes it conducts its operations in substantial 
compliance with applicable environmental and occupational health and safety 
laws.  The Company does not expect to incur material capital expenditures for 
environmental compliance during its current or succeeding fiscal year.  
However, as is the case with manufacturers in general, if a release of 
hazardous substances occurs on or from the Company's properties or at any 
associated offsite disposal location, if contamination from prior activities 
is discovered at any of the Company's properties or if non-compliance with 
environmental regulations or permits is discovered, the Company may be held 
liable and the amount of such liability could be material.  In connection 
with the Trylon and MSTI acquisitions, MascoTech has agreed to indemnify the 
Company for certain environmental matters, including replacement of 
underground storage tanks at the Traverse City facilities and any remediation 
that may be required at the Kendallville facility.

ITEM 4.   SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

Operations and Financial Condition" which appears in the Company's 1996

ITEM 8.   FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

     The information required by Item 8 is incorporated herein by reference 
to the consolidated financial statements, notes thereto and Report of 
Independent Public Accountants thereon which appear beginning on page F-2 of 
the Company's preliminary prospectus dated March 25, 1997 which is attached 
hereto as Exhibit 99.1.

     Management of the Company is responsible for the financial information 
and representations contained in the consolidated financial statements and 
other sections of the 1996 Annual Report.  The consolidated financial 
statements have been prepared in conformity with generally accepted 
accounting principles and therefore include certain amounts based on 

                                     -10-

<PAGE>

management's best estimates and judgments.  The financial information 
contained elsewhere in the 1996 Annual Report is consistent with that in the 
consolidated financial statements.

     The Company maintains internal accounting control systems which 
management believes provide reasonable assurance that the Company's assets 
are properly safeguarded and accounted for, that the Company's books and 
records properly reflect all transactions, and that the Company's policies 
and procedures are implemented by qualified personnel.  Reasonable assurance 
is based upon the recognition that the cost of an internal control system 
should not exceed the related benefits.

     The Audit Committee of the Board of Directors meets with representatives 
of management and Arthur Andersen LLP, the Company's independent public 
accountants, on financial reporting matters and the evaluation of internal 
accounting controls.  The independent public accountants have free access to 
meet with the Audit Committee, without the presence of management, to discuss 
any appropriate matters.

     Arthur Andersen LLP is engaged to express an opinion as to whether the 
consolidated financial statements present fairly, in all material respects 
and in accordance with generally accepted accounting principles, the 
financial position, results of operations and cash flows of the Company.  
Solely for purposes of planning and performing their audit of the Company's 
1996 financial statements, Arthur Andersen LLP obtained an understanding of, 
and selectively tested, certain aspects of the Company's system of internal 
controls.

(1)  On April 15, 1993, the Company acquired R.J. Tower Corporation (prior
thereto, the "Predecessor") in a transaction by an investor group led by a
subsidiary of Onex Corporation, J2R Partners and certain others, including
members of management.  Accordingly, the information provided for the year ended
December 31, 1992 and for the three and one-half month period ended April 14,
1993 is not comparable.  In addition, operating data of the Predecessor for the
period January 1, 1993 to April 14, 1993 have been combined for discussion
purposes with the operating data of the Company for the eight and one-half month
period ended December 31, 1993, without giving effect to purchase accounting or
the impact of the financing of the acquisition of R.J. Tower.

                       MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                    RESULTS OF OPERATIONS AND FINANCIAL CONDITION




COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995

REVENUES

    Revenues for the year ended December 31, 1996 increased by $177.1 million,
or 79.5%, to $399.9 million compared to $222.8 million for the year ended
December 31, 1995.  Approximately $134.3 million of the increase in revenues
over 1995 is attributable to the acquisitions of MascoTech Stamping
Technologies, Inc. ("MSTI") in May 1996 and Trylon Corporation ("Trylon") in
January 1996.  The remaining increase is due to new business awarded to the
Company, including business relating to the Ford Escort, Econoline and
Expedition, Dodge Ram Club Cab pick-up and Toyota Camry.  These increases were
partially offset by production decreases in the first half of the year on key
models served by the Company, including the Ford Aerostar, Villager, Econoline
and Chrysler Intrepid/Concorde/Vision.

COST OF SALES

    Cost of sales as a percentage of revenues for the year ended December 31,
1996 was 84.6% compared to 83.2% for the year ended December 31, 1995.  The
decrease in gross margin was due to a higher proportion of components purchased
from outside suppliers as a result of the MSTI and Trylon acquisitions and
launch costs associated with new business.  These decreases were partially
offset by operating efficiencies and enhanced productivity.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses increased to $20.0 million, or
5.0% of revenues, for the year ended December 31, 1996 compared to $14.3
million, or 6.4% of revenues, for the year ended December 31, 1995. The
percentage decrease related to revenues reflects the economies of scale of
higher gross sales.  The increased expense was due primarily to incremental
costs associated with the Company's acquisitions of MSTI and Trylon in 1996.

AMORTIZATION EXPENSE

    Amortization expense for the year ended December 31, 1996 was $2.2 million
compared to $1.2 million for the year ended December 31, 1995.  The increase was
due to incremental goodwill amortization related to the acquisitions of MSTI and
Trylon.

<PAGE>

INTEREST EXPENSE

    Interest expense for the year ended December 31, 1996 was $5.1 million
compared to $1.8 million for the year ended December 31, 1995.  The increase was
due principally to increased borrowings incurred to fund the acquisitions of
MSTI and Trylon, partially offset by the application of the proceeds from the
June 1996 offering of 2,232,900 shares of common stock at $24.50 per share, and
the absence of capitalization of interest costs for the new Bardstown, Kentucky
plant that was under construction during 1995.

INCOME TAXES

    The effective income tax rate was 39.9% for the year ended December 31,
1996 and 40.0% for the year ended December 31, 1995.  The effective rates
differed from the statutory rates primarily as a result of state taxes and
nondeductible goodwill amortization.

COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994

REVENUES

    Revenues for the year ended December 31, 1995 increased $57.3 million, or
34.6%, to $222.8 million compared to $165.5 million for the year ended December
31, 1994.  Revenues increased despite production decreases on key vehicles
served by the Company including the Ford Escort, Taurus/Sable, and Econoline and
Chrysler Intrepid/Concorde/Vision.  These decreases were offset by new business
that began production during the year and the full year effects of the Company's
acquisitions of Edgewood Tool and Manufacturing Company and its affiliate, Ann
Arbor Assembly Corporation (Edgewood) in May 1994 and Kalamazoo Stamping and Die
Company (Kalamazoo) in June 1994.

COST OF SALES

    Cost of sales, as a percentage of revenues, decreased to 83.2% for the year
ended December 31, 1995 compared to 86.4% for the year ended December 31, 1994.
The improvement in gross margin was a result of the productivity improvement
initiatives in place and synergies realized from the acquisitions of Edgewood
and Kalamazoo.  These were partially offset by higher raw material costs.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

    Selling, general and administrative expenses increased to $14.3 million, or
6.4% of revenues, for the year ended December 31, 1995 compared to $7.4 million,
or 4.5% of revenues, for the year ended December 31, 1994.  The increased
expense was due in part to the full year effect of the acquisitions of Edgewood
and Kalamazoo combined with the

<PAGE>

incremental engineering, technical and development costs associated with future
programs.

OTHER

    Amortization expense increased to $1.2 million for the year ended December
31, 1995 from $.8 million for the year ended December 31, 1994 due to
incremental goodwill amortization related to the Company's 1994 acquisitions.
Interest expense decreased to $1.8 million in 1995 from $1.9 million in 1994.
The decrease is due to the effect of the application of the proceeds from the
Company's IPO to reduce indebtedness.  The provision for income taxes was at an
effective rate of 40.0% for the year ended December 31, 1995 and 40.7% for the
year ended December 31, 1994.  The effective rates were higher than federal
statutory rates as a result of nondeductible goodwill amortization and state
income taxes.

SEASONALITY

    The Company's performance is dependent on automotive vehicle production,
which is seasonal in nature.  The third calendar quarter is historically the
weakest, due to the impact of OEM plant shutdowns in July for vacation and model
changeovers.  Additionally, general industry levels are only a partial
explanation of volume changes throughout the year.  Individual vehicle platforms
are also a cause of variations in revenues depending upon market response and
acceptance of the specific platform models.

LIQUIDITY AND CAPITAL RESOURCES

    At December 31, 1996, the Company had no indebtedness outstanding under the
revolving credit facility portion of its Credit Agreement.  The Credit
Agreement, as amended, consists of a revolving credit facility with a committed
amount of $75.0 million (subject to eligible accounts receivable and inventory,
as defined in the Credit Agreement, which exceeded $75.0 million at December 31,
1996).  The Credit Agreement matures in January 2001 and bears interest at
variable rates equal to, at the Company's option, either a prime-based rate or
LIBOR plus a variable margin.  The Credit Agreement is secured by substantially
all of the assets of the Company and provides for the issuance of up to $50
million in letters of credit to collateralize the outstanding IRBs described
below.

    At December 31, 1996, the Company also had $43.8 million of indebtedness
outstanding pursuant to IRBs issued with the City of Bardstown, Kentucky.
Proceeds from these IRBs were used to finance construction of a 240,000 square
foot manufacturing facility and the related purchase of equipment.  The
Bardstown IRBs, which mature on June 1, 2024 and March 1, 2025, are
collateralized by a letter of credit.  As of December 31, 1996, $34.2 million of
the proceeds had been expended or committed for the first phase of the facility
and related equipment.  The unexpended

<PAGE>

proceeds from the Bardstown IRBs of $10.8 million at December 31, 1996, are
invested in treasury securities and will be used to finance the second phase of
the facility.  These IRBs bear interest at a floating rate which is adjusted
weekly as determined by the bond remarketing agent (5.8% at December 31, 1996).
The second phase of the facility, which includes the purchase and installation
of additional processing equipment, is anticipated to be completed by the end of
1998.

    At December 31, 1996, the Company had $2.9 million in outstanding
indebtedness relating to IRBs issued in connection with the construction of its
Auburn, Indiana plant.  The Auburn IRBs are collateralized by a letter of
credit, certain equipment and a mortgage on the Company's Auburn, Indiana plant.
The Auburn IRBs are payable in annual installments of $720,000 through September
2000 and bear interest at a floating rate which is adjusted weekly as determined
by the bond remarketing agent (4.4% at December 31, 1996).

    On January 16, 1996, the Company acquired all of the outstanding common
stock of Trylon for total cash consideration of approximately $25 million, which
included transaction costs.  To finance the acquisition, the Company incurred a
$25.0 million term loan, which was repaid in May 1996 using a portion of the
proceeds from the sale of the Senior Notes and borrowings under its revolving
credit facility.

    On May 31, 1996, the Company purchased all of the outstanding common stock
of MSTI from MascoTech, Inc. (MascoTech) for an aggregate purchase price of
approximately $79 million, including payment of related fees and expenses.
Pursuant to the terms of the acquisition, the Company is required to make
additional earn-out payments to MascoTech if certain operating targets are
achieved by the MSTI facilities in the first three years following the
acquisition.  If all such operating targets are met, the total payments will not
exceed $30 million.

    The Company financed the cash portion of the purchase price of MSTI through
the issuance in two series of Senior Notes having an aggregate principal amount
of $65.0 million.  The $40.0 million of Series A Senior Notes have a final
maturity on June 1, 2006 and require annual principal payments commencing on
June 1, 2000 and continuing every year thereafter until their final maturity.
The $25.0 million of Series B Senior Notes have a final maturity on June 1, 2008
and require annual principal payments commencing on June 1, 2004 and continuing
every year thereafter until their final maturity.  The Senior Notes require the
Company to make semi-annual interest payments commencing December 1, 1996.  Net
proceeds from the sale of the Senior Notes in excess of the amounts used to
finance the cash portion of the MSTI acquisition were used, together with
borrowings under the revolving credit facility, to repay in full the remaining
balance outstanding on the $25 million term loan incurred by the Company in
connection with the Trylon acquisition.

    In June 1996, the Company completed an offering of 2,232,900 shares of
Common Stock at an offering price of $24.50 per share (Offering).  Approximately
$32

<PAGE>

million of the net proceeds from the Offering were used by the Company to retire
borrowings under its Credit Agreement.  The remaining proceeds are included in
cash and cash equivalents in the December 31, 1996 consolidated balance sheet
and will be used for other general corporate purposes, which may include
prepayment of other indebtedness, acquisitions or capital expenditures.

    During the year ended December 31, 1996, the Company generated $30.0
million of cash from operations, which was partially used to fund capital
expenditures.

    The Company has made substantial investments in manufacturing technology
and product design capability to support its products.  The Company made capital
expenditures of approximately $16.3 million for the year ended December 31,
1996, primarily for equipment and dedicated tooling purchases related to new or
replacement programs.


    On January 27, 1997, the Company entered into an agreement to acquire and
assume substantially all of the assets and liabilities of Automotive Products
Company (APC), a division of A.O. Smith Corporation, for $625 million in cash,
subject to certain adjustments.  APC, which had revenues of approximately $860
million for the year ended December 31, 1996, designs and manufactures frames,
frame components, engine cradles, suspension components and modules for the
North American automotive and heavy truck industries.  This acquisition is
expected to close during the second quarter of 1997.  This acquisition will be
accounted for as a purchase and, accordingly, APC's assets and liabilities will
be recorded at fair value as of the acquisition date, with any excess purchase
price recorded as goodwill.

    In connection with this acquisition, the Company agreed to enter into a new
credit facility.  This new facility will provide a total financing commitment of
up to $865 million.  The specific terms and conditions of this new credit
facility are currently being negotiated with the bank.  The new credit facility
will also include certain restrictive covenants, which the Company expects will
be similar in nature to those in its existing credit agreement.  This facility
will become effective contemporaneously with the completion of the acquisition
of APC.

    As part of this refinancing, the Company expects a portion of the proceeds
from the new credit facility will be used to retire the Senior Notes.  If the
Senior Notes are retired, the Company will record an extraordinary loss of
approximately $3 million, net of income taxes, related to prepayment penalties
and the write-off of previously capitalized deferred financing costs.

    On February 18, 1997, the Company filed a registration statement on Form
S-3 with the Securities and Exchange Commission related to the proposed sale of
up to 8,500,000 shares of the Company's Common Stock to the public.  The Company
expects this offering will be completed early in the second quarter of 1997.
Proceeds from this

<PAGE>

offering will be used to fund a portion of the purchase price related to the
acquisition of APC.

    The Company believes the borrowing availability under a new credit
agreement, together with funds generated by operations, should provide the
Company with the liquidity and capital resources to pursue its business strategy
through 1997, with respect to working capital, capital expenditures and other
operating needs.  Under present conditions, management does not believe access
to funds will restrict its ability to pursue its acquisition strategy.

EFFECTS OF INFLATION

    Inflation generally affects the Company by increasing the interest expense
of floating rate indebtedness and by increasing the cost of labor, equipment and
raw materials.  Management believes that inflation has not significantly
impacted the Company's business over the past 12 months.  However, because
selling prices generally cannot be increased until a model changeover, the
effects of inflation must be offset by productivity improvements and volume from
new business awards.

                      NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


1.  ORGANIZATION AND BASIS OF PRESENTATION:

    Tower Automotive, Inc. (the Company) designs and manufactures structural
    metal stampings and assemblies for use by original equipment manufacturers
    in the North American automotive industry and has manufacturing facilities
    located in Michigan, Indiana, Kentucky and Ohio.

2.  SIGNIFICANT ACCOUNTING POLICIES:

    PRINCIPLES OF CONSOLIDATION:

    The accompanying consolidated financial statements include the accounts of
    Tower Automotive, Inc. and its wholly owned subsidiaries.  All material
    intercompany accounts and transactions have been eliminated in
    consolidation.

    CASH EQUIVALENTS:

    Cash equivalents consist of highly liquid investments with an original
    maturity of three months or less.  Cash equivalents are stated at cost
    which approximates fair value.

    INVENTORIES:

    Inventories are valued at the lower of first-in, first-out (FIFO) cost or
    market.

    Inventories consisted of the following (in thousands):

                                          December 31,

                                    --------       --------




    CUSTOMER TOOLING AND OTHER DESIGN COSTS:

    Customer tooling represents costs incurred by the Company in the
    development of new tooling used in the manufacture of the Company's
    products.  Once customer approval is obtained for the manufacture of a new
    product, the Company is reimbursed by its customers for the cost of certain
    of the tooling, at which time the tooling becomes the property of the
    customers.

    In addition, the Company has certain other tooling and design costs related
    to previously proven product designs which are reimbursed by the Company's
    customers as the related product is sold through an incremental increase in
    each product's unit selling price.

<PAGE>

    Such costs are capitalized and amortized using the unit of production
    method over the life of the related tool.  Amounts capitalized and included
    in other assets were $3.7 million at December 31, 1996 and $3.8 million at
    December 31, 1995.  If the Company forecasts that the amount of capitalized
    tooling and design costs exceeds the amount to be realized through the sale
    of product, a loss is recognized currently.

    PROPERTY, PLANT AND EQUIPMENT:

    Property, plant and equipment acquired in the acquisitions discussed in
    Note 3 was recorded at its fair value, determined based on appraisals, as
    of the respective acquisition dates.  Additions to property, plant and
    equipment following the acquisitions are stated at cost.  For financial
    reporting purposes, depreciation and amortization are provided using the
    straight-line method over the following estimated useful lives:

         Buildings and improvements    15 to 30 years
         Machinery and equipment        3 to 20 years

    Accelerated depreciation methods are used for tax reporting purposes.

    Start-up costs related to major facilities and new platforms are
    capitalized and amortized over the life of the related platform, generally
    five years.  The unamortized start-up cost balance was $1,011,000 at
    December 31, 1996 and $876,000 at December 31, 1995.

    Interest is capitalized during the construction of major facilities and is
    amortized over the related estimated useful lives.  Interest costs of
    $1,157,000 were capitalized during the year ended December 31, 1995.  No
    interest was capitalized during the year ended December 31, 1996.

    Maintenance and repairs are charged to expense as incurred.  Major
    betterments and improvements which extend the useful life of the related
    item are capitalized and depreciated.  The cost and accumulated
    depreciation of property, plant and equipment retired or otherwise disposed
    of are removed from the related accounts, and any residual values are
    charged or credited to income.

    OTHER ASSETS:

    Goodwill represents the excess of the purchase price over the fair value of
    the net assets acquired and is being amortized on a straight-line basis
    over 40 years.  Debt issue costs are amortized on a straight-line basis
    over the term of the related obligations.

    The Company periodically evaluates whether events and circumstances have
    occurred which may affect the estimated useful life or the recoverability
    of the remaining balance of its goodwill and other long-lived assets.  If
    such events or circumstances were to indicate that the carrying amount of
    these assets were not recoverable, the Company would estimate the future
    cash flows expected to result from the use of the assets and their eventual
    disposition.  If the sum of the expected future cash flows (undiscounted
    and without interest charges) were less than the carrying amount of
    goodwill, the Company would recognize an impairment loss.

<PAGE>

    INCOME TAXES:

    The Company accounts for income taxes under the liability method, whereby
    deferred income taxes are recognized at currently enacted income tax rates
    to reflect the tax effect of temporary differences between the financial
    reporting and tax bases of assets and liabilities.

    NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE:

    Net income per common and common equivalent share is computed by dividing
    net income applicable to common stockholders by the weighted average number
    of common and common stock equivalent shares outstanding during each period
    presented.  Common stock issued and common stock options granted within one
    year immediately preceding the initial public offering of common stock
    (Common Stock) discussed in Note 4 at prices below the public offering
    price have been reflected in the net income per share calculation as if
    they had been outstanding for all periods presented.  Net income for
    purposes of computing net income per common and common equivalent share
    reflects the elimination of interest expense on the convertible
    subordinated notes, net of the related income tax benefit.

    USE OF ESTIMATES:

    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 and
    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.  The ultimate results could differ from those
    estimates.

3.  ACQUISITIONS:

    On May 4, 1994, the Company acquired the operating assets and assumed
    certain operating liabilities and indebtedness of Edgewood Tool and
    Manufacturing Company (Edgewood), a manufacturer of hood and deck lid
    hinges and structural metal components for the automotive industry, for
    total consideration of $24.6 million in cash and assumed indebtedness and
    the issuance of $5.0 million of Convertible Subordinated Notes.  In
    addition, the Company entered into a five year employment agreement with
    Edgewood's former president and issued an option to acquire 102,984 shares
    of Common Stock at an exercise price of $6.55 per share.

    On June 29, 1994, the Company acquired the capital stock of Kalamazoo
    Stamping and Die Company (Kalamazoo), a supplier of structural metal
    stampings and assemblies for the automotive industry, for net consideration
    of approximately $12.3 million in cash.

    On January 16, 1996, the Company acquired all of the outstanding common
    stock of Trylon Corporation (Trylon) for total consideration of
    approximately $25 million.  The acquisition was financed with the proceeds
    of a $25 million term loan.  Trylon manufactures metal stampings and
    assemblies for the North American automotive industry from four facilities
    in Traverse City, Michigan.


                                        - 3 -


<PAGE>

    On May 31, 1996, the Company acquired all of the outstanding common stock
    of MascoTech Stamping Technologies, Inc. (MSTI), a wholly owned subsidiary
    of MascoTech, Inc. (MascoTech).  Consideration consisted of $55 million in
    cash, 785,000 shares of the Company's Common Stock and warrants to acquire
    200,000 shares of the Company's Common Stock at an exercise price of $18
    per share.  The Company may also make additional payments of up to $30
    million to MascoTech if certain operating targets are achieved by the MSTI
    facilities in the first three years following the acquisition.  Based on
    results of operations of the MSTI facilities through December 31, 1996, no
    contingent payments are due.  MSTI manufactures metal chassis and
    suspension components and assemblies for the North American automotive
    industry from facilities in Ohio, Indiana and Michigan.

    These acquisitions have been accounted for using the purchase method of
    accounting and, accordingly, the assets acquired and liabilities assumed
    have been recorded at fair value as of the dates of the acquisitions.  The
    assets and liabilities of Trylon and MSTI have been recorded based upon
    preliminary estimates of fair value as of the dates of acquisition.  The
    Company does not believe the final allocations of the purchase price will
    be materially different than the preliminary allocations.  The excess of
    the purchase price over the fair value of the assets acquired and
    liabilities assumed has been recorded as goodwill.  Results of operations
    for these acquisitions have been included in the accompanying consolidated
    financial statements since the dates of acquisition.  The accompanying
    unaudited consolidated pro forma results of operations for the years ended
    December 31, 1996 and 1995 give effect to the Offering (as defined in Note
    4) and the acquisitions of Trylon and MSTI as if they were completed at the
    beginning of the respective periods.  The unaudited pro forma financial
    information does not purport to represent what the Company's results of
    operations would actually have been if such transactions in fact had
    occurred at such date or to project the Company's results of future
    operations (in thousands, except per share data):

4.  STOCKHOLDERS' INVESTMENT:

    PUBLIC OFFERINGS OF COMMON STOCK:

    In August 1994, the Company completed an initial public offering, including
    shares issued pursuant to the underwriters' over-allotment option, of
    4,887,500 shares of its Common Stock at $11.50 per share resulting in net
    proceeds to the Company of approximately $51.3 million.

    During 1996, the Company completed an offering of 2,232,900 shares of its
    Common Stock at an offering price of $24.50 per share (the Offering)
    resulting in net proceeds of approximately $51.3 million.  Proceeds from
    the Offering were used by the Company to retire borrowings under its
    secured credit agreement and for general corporate purposes.

    PRIVATE PLACEMENTS:

    During 1993, the Company sold 522,640 shares of its Common Stock to certain
    employees for aggregate proceeds of approximately $981,000.  Approximately
    $434,000 of this amount was financed through notes to the Company which
    bear interest at prime plus 1% (9.25% at December 31, 1996 and 9.5% at
    December 31, 1995) and are due in 1998.  These notes are reflected as a
    reduction of stockholders' investment in the accompanying consolidated
    financial statements.  Approximately $330,000 and $248,000 of these notes
    had been collected as of December 31, 1996 and 1995.

    As a component of the financing for the acquisition of Edgewood in May 1994
    (see Note 3), the existing stockholders and members of the Company's
    management participated in a $4.1 million private placement of 1,585,365
    shares of Common Stock, resulting in net cash proceeds to the Company of
    $3.7 million.  Approximately $404,000 of this amount was financed through
    notes to the Company which bear interest at prime plus 1% and are due in
    1999.  These notes are reflected as a reduction of stockholders' investment
    in the accompanying consolidated financial statements.  Approximately
    $333,000 and $93,000 of these notes had been collected as of December 31,
    1996 and 1995.

    STOCK OPTION PLAN:

    The Company sponsors the 1994 Key Employee Stock Option Plan (the Stock
    Option Plan), under which any person who is a full-time, salaried employee
    of the Company (excluding non-management directors) is eligible to
    participate in the Stock Option Plan (an Employee Participant).  A
    committee of the board of directors selects the Employee Participants and
    determines the terms and conditions of the options.  The Stock Option Plan
    provides for the issuance of options up to 500,000 shares of Common Stock
    at exercise prices equal to the stock market price on the date of grant to
    Employee

    INDEPENDENT DIRECTOR STOCK OPTION PLAN:

    In February 1996, the Company's board of directors approved the Tower
    Automotive, Inc. Independent Director Stock Option Plan (the Director
    Option Plan) that provides for the issuance of options to Independent
    Directors, as defined, to acquire up to 100,000 shares of the Company's
    Common Stock, subject to certain adjustments reflecting changes in the
    Company's capitalization.  The option exercise price must be at least equal
    to the fair value of the Common Stock at the time the option is issued.
    Vesting is determined by the Board of Directors at the date of grant and in
    no event can be less than six months from the date of grant.  As of
    December 31, 1996, the Company had granted stock options under this plan to
    acquire 22,500 shares of Common Stock at an exercise price of $15.125 per
    share.  None of these director options were exercisable or vested at
    December 31, 1996.

    EMPLOYEE STOCK PURCHASE PLAN:

    The Company also sponsors an employee stock discount purchase plan which
    provides for the sale of up to 500,000 shares of the Company's Common Stock
    at discounted purchase prices, subject to certain limitations.  The cost
    per share under this plan is 85% of the market value of the Company's
    Common Stock at the date of purchase, as defined.  During the year ended
    December 31, 1996, 18,350 shares of Common Stock were issued to employees
    pursuant to this plan and during the year ended December 31, 1995, 4,143
    shares of Common Stock were issued.  The weighted average fair value of
    shares sold in 1996 and 1995 were $14.32 and $8.11, respectively.

    STOCK-BASED COMPENSATION PLANS:

    As discussed above, the Company has two stock option plans, the Stock
    Option Plan and the Independent Director Stock Option Plan, and an Employee
    Stock Purchase Plan.  The


                                        - 6 -


<PAGE>

    Company accounts for these plans under APB Opinion No. 25, under which no
    compensation cost has been recognized.  Had compensation cost for these
    plans been determined consistent with Statement of Financial Accounting
    Standards No. 123, "Accounting for Stock-Based Compensation," (SFAS No.
    123), the Company's pro forma net income and pro forma earnings per share
    would have been as follows (in thousands):

                                                  Years Ended December 31,
                                                  ------------------------
                                                     1996          1995
                                                  ---------     ----------

Net income applicable        As Reported          $  20,765     $  12,247
  to common stockholders     Pro Forma            $  20,611     $  12,213

Net income per common and    As Reported            $  1.55       $  1.05
  common equivalent share    Pro Forma              $  1.54       $  1.04


    Because the SFAS No. 123 method of accounting has not been applied to
    options granted prior to January 1, 1995, the resulting pro forma
    compensation cost may not be representative of that to be expected in
    future years.  The effect of the stock offered under the Employee Stock
    Purchase Plan was not material for 1996 and 1995.

    The fair value of each option grant is estimated on the date of the grant
    using the Black-Scholes option pricing model with the following weighted
    average assumptions:  risk free interest rates of 5.57% in 1996 and 6.5%,
    6.9% and 6.93% in 1995; expected life of seven years for 1996 and 1995;
    expected volatility of 56% in 1996 and 35%, 37% and 41% in 1995.

    OTHER COMMON STOCK EQUIVALENTS:

    In connection with the acquisition of Edgewood in May 1994, the Company
    issued an option to acquire 102,984 shares of Common Stock at an exercise
    price of $6.55 per share.  The options expire in 2004.  As of December 31,
    1996, 34,328 options were vested and exercisable.

    In connection with the acquisition of MSTI in May 1996, the Company issued
    warrants to MascoTech to acquire 200,000 shares of Common Stock at an
    exercise price of $18 per share.  The warrants expire in 2006.

    Included in the Company's credit agreement, as amended (the Credit
    Agreement), is a revolving credit facility which provides for borrowings of
    up to $75 million.  The Credit Agreement also provides for the issuance of
    up to $50 million in letters of credit to collateralize the outstanding
    industrial development revenue bonds.  Available credit under this
    agreement is limited to eligible accounts receivable and inventories, as
    defined, which exceeded $75 million at December 31, 1996.  The weighted
    average interest rate for borrowings under the revolving credit facility
    was 6.1% for the year ended December 31, 1996 and 7.4% for the year ended
    December 31, 1995.  In connection with the transaction described in Note
    10, the Company obtained a commitment from a bank to refinance the existing
    Credit Agreement.

    The Company financed the cash portion of the MSTI acquisition through the
    issuance in two series of Senior Notes having an aggregate principal amount
    of $65 million.  The Senior Notes require the Company to make semi-annual
    interest payments commencing December 1, 1996, while principal is payable
    in varying annual installments beginning in 2000.  Net proceeds from the
    sale of the Senior Notes in excess of the amounts used to finance the cash
    portion of the MSTI acquisition, together with borrowings under the
    revolving credit facility, were used to repay in full the remaining balance
    outstanding on a $25 million term loan incurred by the Company in
    connection with the acquisition of Trylon.

    In connection with the acquisition of Edgewood in May 1994, the Company
    issued the $5.0 million Convertible Subordinated Notes, which generally are
    convertible at any time into 823,874 shares of Common Stock.  The
    Convertible Subordinated Notes are subject to prepayment in the event of,
    and become convertible upon, a sale of the Company and are subordinated to
    all other debt of the Company which is not expressly subordinated to the
    Convertible Subordinated Notes.  As of December 31, 1996, approximately
    $2.5 million of these notes had been converted into 410,529 shares of
    Common Stock.

    In June 1994 and March 1995, the Company issued $25.0 million and $20.0
    million, respectively, of industrial development revenue bonds related to
    the construction and equipping of a manufacturing facility in Bardstown,
    Kentucky.  The bonds are collateralized by letters of credit.    The
    facility will be completed in two phases.  The undispersed proceeds from
    these bonds are invested in treasury securities and reflected as restricted
    cash in the accompanying consolidated balance sheets. The Company also has
    approximately $2.9 million in outstanding indebtedness relating to
    industrial development revenue bonds issued in connection with the
    construction of its Auburn, Indiana plant.  The bonds are collateralized by
    a letter of credit, certain equipment and a mortgage on this plant.

    The debt agreements described above contain various restrictive covenants
    which, among other matters, require the Company to maintain certain
    financial ratios.  The agreements also limit additional indebtedness,
    capital expenditures and cash dividends.  The Company was in compliance
    with all debt covenants as of December 31, 1996 and 1995.

    As of December 31, 1995, the Company had provided a valuation allowance for
    certain deferred tax assets as their realization was not reasonably
    assured.  During 1996, the Company determined it was more likely than not
    that the deferred tax assets would be realized.  Accordingly, the valuation
    allowance was eliminated as a reduction to goodwill.

    providing defined benefits to certain Michigan hourly employees.
    Contributions to the pension plan are based on rates set forth in the
    Company's union contracts.  The expense related to this plan was $852,000
    for the year ended December 31, 1996, $788,000 for the year ended December
    31, 1995 and $680,000 for the year ended December 31, 1994.  The plan was

    The Company also has a qualified profit sharing retirement plan and 401(k)
    employee savings plan covering certain salaried and hourly employees.  The
    expense related to these plans was $2,803,000 during 1996, $1,157,000
    during 1995 and $1,137,000 during 1994.

    The Company sponsors 401(k) employee savings plans covering certain union
    employees.  The Company matches a portion of the employee contributions
    made to these plans.  The expense under these plans in each of the three
    years in the period ended December 31, 1996 was not material.

    The Company's UAW Retirement Income Plan covers substantially all union
    employees at its Kalamazoo and Bluffton facilities.  Benefits under the
    plan are based on years of service.  Contributions by the Company are
    intended to provide not only for benefits attributed to service to date,
    but also for those benefits expected to be earned in the future.  The
    Company's funding policy is to contribute annually the amounts sufficient
    to meet the higher of the minimum funding requirements set forth in the
    Employee Retirement Income Security Act of 1974 or the minimum funding
    requirements under the Company's UAW contract.  Net pension expense for the
    years ended December 31, 1996, 1995 and 1994 consisted of the following (in

    The discount rate used in determining the actual present value of the
    projected benefit obligation was 7.5% in 1996 and 7% 1995.  The expected
    long-term rate of return on plan assets was 8% for December 31, 1996 and
    1995.  Plan assets consist principally of mutual funds invested in bonds
    and equity securities.

    DEFERRED COMPENSATION PLAN:

    The Company had salary continuation agreements with three employees which
    provided for certain payments beginning with the later of retirement or
    attainment of age 62, or in the event of death or disability.  During 1995
    two of these employees received payments totaling $529,000 as a result of
    their retirement.  The expense under this plan has not historically been
    significant.  The Company's total obligation under these agreements was
    $334,000 as of December 31, 1996 and $318,000 as of December 31, 1995 and
    was included in noncurrent liabilities in the accompanying consolidated
    balance sheets.

    POSTRETIREMENT PLANS:

    The Company provides certain medical insurance benefits for retired
    employees.  Certain employees of the Company are eligible for these
    benefits if they remain employed until age 55 or 59 and fulfill other
    eligibility requirements specified by the plans.  Certain retirees between
    the ages of 55 and 62 must contribute 100% of the group rate for active
    employees.  No contributions are required for retirees 62 or older.
    Benefits are continued for dependents of eligible retiree participants
    after the death of the retiree.

    periods ended December 31 (in thousands):

<PAGE>

    The projected postretirement benefit obligation is calculated using a 7.0%
    annual rate of increase in per capita claims cost in 1996 and 7.5% in 1995.
    This rate is assumed to decrease by one half of one percent per year
    through 1997.  In 1998, the rate is assumed to be 6.5% and remain at that
    level for all years thereafter.

    If the health care cost trend rate were increased one percentage point, the
    accumulated postretirement benefit obligation and the aggregate of the
    service and interest cost discussed above would have increased by 12%.

    LEASES:

    The Company leases office and manufacturing space, including the lease
    described in Note 9, and certain equipment under operating lease agreements
    which require it to pay maintenance, insurance, taxes and other expenses in
    addition to annual rentals.  Future annual rental commitments at December
    31, 1996 under these operating leases are as follows (in thousands):

    in Note 3.

9.  RELATED PARTY TRANSACTIONS:

    The Company leases a manufacturing facility from a partnership whose major
    partners are former stockholders of Edgewood and are current employees of
    the Company.  The lease expires February 28, 1999.  Expense under this
    lease was $475,000 for the year ended December 31, 1996, $454,000 for the
    year ended December 31, 1995 and $298,000 for the period from the
    acquisition of Edgewood through December 31, 1994.

    The Company has made payments to Hidden Creek Industries, an affiliate of
    the Company, for certain acquisition related and other management services
    totaling  $750,000 during 1996 and $833,000 during 1994.

10. AGREEMENT TO ACQUIRE AUTOMOTIVE PRODUCTS COMPANY:

    On January 27, 1997, the Company entered into an agreement to acquire and
    assume substantially all of the assets and liabilities of Automotive
    Products Company (APC), a division of A.O. Smith Corporation, for $625
    million in cash, subject to certain adjustments.  APC, which had revenues
    of approximately $860 million for the year ended December 31, 1996, designs
    and manufactures frames, frame components, engine


                                        - 14 -


<PAGE>

    cradles, suspension components and modules for the North American
    automotive and heavy truck industries.  This acquisition is expected to
    close during the second quarter of 1997.  This acquisition will be
    accounted for as a purchase and, accordingly, APC's assets and liabilities
    will be recorded at fair value as of the acquisition date, with any excess
    purchase price recorded as goodwill.

    In connection with this acquisition, the Company agreed to enter into a new
    credit facility with a bank which will provide a total financing
    availability of up to $865.  The specific terms and conditions of this new
    credit facility are currently being negotiated with the bank.  The new
    credit facility will also include certain restrictive covenants, which the
    Company expects will be similar in nature to those in its existing credit
    agreement.  This facility will become effective contemporaneously with the
    completion of the acquisition discussed above.

    As part of this refinancing, the Company expects a portion of the proceeds
    from the new credit facility will be used to retire the Senior Notes
    discussed in Note 5.  If the Senior Notes are retired, the Company will
    record an extraordinary loss of approximately $3 million, net of income
    taxes, related to prepayment penalties and the write-off of previously
    capitalized deferred financing costs.

    On February 18, 1997, the Company filed a registration statement on Form
    S-3 with the Securities and Exchange commission related to the proposed
    sale of up to 8,500,000 shares of the Company's Common Stock to the public.
    The Company expects this offering will be completed early in the second
    quarter of 1997.  Proceeds from this offering will be used to fund a
    portion of the purchase price related to the acquisition discussed above.

    The acquisition of APC will be accounted for as a purchase and,
    accordingly, APC's assets and liabilities will be recorded at fair values
    as of the acquisition date.  Following is an unaudited pro forma balance
    sheet of the Company, based on preliminary estimates of the allocation of
    the purchase price, as if the acquisition of APC and the offering described
    above had been completed as of December 31, 1996 (in thousands):

                                  THE COMPANY
 
GENERAL
 

    The Company is a leading designer and producer of high-quality body
structure components and assemblies used by the major North American automotive
original equipment manufacturers ("OEMs"), Ford, Chrysler and General Motors,
and certain foreign OEMs with manufacturing operations in North America
("Transplants"), including Honda, Toyota, Nissan and Mazda. The Company's
current products range from large structural stampings and assemblies, such as
body pillars, chassis, suspension and floor pan components and major housing
assemblies, to engineered assemblies, such as hood and deck lid hinges and brake
components. On January 27, 1997, the Company agreed to acquire A.O. Smith's APC
division, a leading manufacturer of light truck frames, automotive engine
cradles and other structural and suspension components, assemblies and modules
used by major North American OEMs and Transplants. Following the APC
Acquisition, the Company believes it will be one of the largest independent
suppliers of structural components and assemblies to the North American
automotive market (based on net sales).

 

    Since its inception in April 1993, the Company's revenues have grown rapidly
through a focused strategy of internal growth and a highly disciplined
acquisition program. During the last three years, the Company has successfully
completed and fully integrated four acquisitions. As a result of such
acquisitions and internal growth, the Company's revenues have increased from
approximately $86 million in 1993 to approximately $474 million in 1996 (pro
forma only for the MSTI Acquisition), representing a compound annual growth rate
of approximately 76%. The Company's North American content per vehicle has
increased from $6.23 in 1993 to $26.74 in 1996 on an actual basis. The APC
Acquisition will be the Company's largest acquisition to date and will increase
the Company's pro forma revenues to approximately $1.3 billion and its pro forma
North American content per vehicle to $77.49 for 1996.

 
    The Company operates in the large and highly fragmented structural segment
of the automotive supply industry, which has recently begun to undergo
significant consolidation. To lower costs and improve quality, OEMs are reducing
their supplier base by awarding sole-source contracts to full-service suppliers
who are able to supply larger portions of a vehicle on a global basis. OEMs'
criteria for supplier selection include not only cost, quality and
responsiveness, but also full-service design, engineering and program management
capabilities. OEMs are increasingly seeking suppliers capable of providing
complete systems or modules rather than suppliers who only provide separate
component parts. In addition, OEMs are increasingly requiring their suppliers to
have the capability to design and manufacture their products in multiple
geographic markets. As a full-service supplier with strong OEM relationships,
the Company expects to continue to benefit from these trends within the
structural segment of the automotive supply industry.
 
                                       3
<PAGE>

    The Company's business objective is to capitalize on the consolidation,
globalization and system/ modular sourcing trends in the automotive supply
industry in order to be the leading provider of structural and suspension
components to OEMs worldwide. The Company's growth strategy focuses on the
identification and pursuit of (i) strategic acquisitions; (ii) modular product
opportunities; (iii) increased vehicle penetration; and (iv) "world car"
opportunities.

 
THE APC ACQUISITION
 
    APC is a leading designer and producer of structural and suspension
components for the automotive, light truck and heavy truck markets. APC's
products include light truck frames, automotive engine cradles, suspension and
other components and heavy truck frame rails. In 1996, over 70% of APC's
revenues was derived from the sale of structural components for light trucks and
sport utility vehicles, a growing segment of the North American automotive
market. APC's customers include the three major North American OEMs as well as
certain Transplants, including Toyota, Nissan, Isuzu and Honda. APC's three
largest customers, Ford, General Motors and Chrysler, accounted for
approximately 46%, 23% and 20%, respectively, of APC's revenues in 1996.
Approximately 11% of APC's revenues in 1996 was derived from the production of
heavy truck frame rails for North American heavy truck OEMs. The Company
believes APC is the largest supplier in this segment, with a market share of
approximately 51% in 1996. APC conducts its operations through 15 facilities
which, when added to the Company's existing 19 facilities, will result in a
total of over seven million square feet of manufacturing floor space.
 
    The Company believes that the APC Acquisition will provide the Company with
several strategic
benefits, including the following:
 

    EXPANDED PRODUCT OFFERINGS AND MODULAR PRODUCT OPPORTUNITIES.  The APC
Acquisition will significantly expand the Company's product offerings by adding
lower body structural components to the Company's existing line of upper body
structural components. In addition, APC's products provide an ideal platform for
developing modular product offerings for the Company's customers. APC's frame
and engine cradle products can be combined with a number of the Company's
existing product offerings, including control arms, suspension components,
exhaust hanger assemblies and spring towers and hangers to deliver more complete
systems or modules to its OEM customers at a lower overall cost. The APC
Acquisition will enable the Company to produce a larger portion of a vehicle,
which the Company believes will afford it significant opportunities to increase
revenues as OEMs continue to consolidate their supplier base. See
"Business--Industry Trends."

 
    INCREASED CUSTOMER PENETRATION.  The APC Acquisition will significantly
expand the Company's penetration within each of the three major North American
OEMs. Following the APC Acquisition, the Company believes it will be the largest
supplier of structural components to Chrysler, the largest supplier of metal
components to Ford and a major supplier of structural components to General
Motors. The APC Acquisition will also expand the Company's penetration within
certain Transplants by doubling the Company's sales to Toyota, expanding its
already significant position at Honda, increasing sales to Nissan and adding
Isuzu as a new customer.
 

    INCREASED PENETRATION IN LIGHT TRUCK SEGMENT AND OTHER KEY MODELS.  The APC
Acquisition will increase the Company's North American content per vehicle from
$26.74 in 1996 to $77.49 on a pro forma basis and will triple the Company's
content per vehicle in the expanding light truck/sport utility market segment,
which segment represented approximately 60% of the Company's pro forma revenues
for 1996. The APC Acquisition will increase the Company's content per vehicle on
key light truck/sport utility vehicles such as the Ford Explorer and Ranger and
the Chrysler Dakota, Durango and Ram as well as on high volume passenger cars
such as the Ford Taurus/Sable and the Chrysler Intrepid/Concorde/Vision. The
Company believes that this increased model penetration will afford it greater
opportunities to supply additional parts and modules for such models.

 
                                       4
<PAGE>
    COMPLEMENTARY NEW TECHNOLOGY.  The APC Acquisition will provide the Company
with a variety of new and enhanced design and manufacturing technology,
including APC's patented three piece side rail frame and patented Simulform-TM-
forming technology, the latter of which may result in cost savings and quality
improvements over conventional stamping technology in certain specialized
applications. In addition, APC's existing hydroforming technology complements
the Company's initiatives in this area. The APC Acquisition will also provide
the Company with additional painting, coating and welding technologies and
advanced logistical parts management systems. The Company believes that these
acquired technologies will provide significant additional opportunities to serve
existing customers and obtain new business.
 

    OPERATIONAL EFFICIENCIES.  The APC Acquisition will provide the Company with
a number of opportunities to reduce costs and improve operational efficiency.
For example, APC currently outsources many of its stamping needs, some of which
will be able to be supplied by the Company's existing stamping facilities. In
addition, the Company's and APC's facilities are geographically located in such
a way as to allow the Company to optimize its management and logistical
capabilities on a regional basis. APC's facilities are strategically located
close to many of its and the Company's major customers, allowing for inventory
and freight cost-savings. The increased size of the Company may also improve the
Company's ability to negotiate more favorable terms on its purchasing and supply
contracts, as well as achieve other operational cost savings.

 
    EXPANDED GLOBAL CAPABILITIES.  OEMs are increasingly demanding that their
suppliers have global production capabilities. APC's presence in China, Japan
and South America complements the Company's current European initiatives to
provide expanded global production capabilities for both North American and
international OEMs. See "Business--Global Initiatives."
 

    The aggregate purchase price of APC is approximately $625 million, plus an
additional $25 million for related fees and expenses and management's estimate
of certain post-closing adjustments. The Company expects to complete the APC
Acquisition by the end of April 1997. Pursuant to the terms of the purchase
agreement, the Company may elect not to complete the APC Acquisition if there is
a material adverse change in the operating results or financial condition of APC
prior to the closing date. Currently, the Company believes that such a change
has not occurred and that it is unlikely that such a change will occur prior to
the closing date. If the APC Acquisition is not completed, the shares of Common
Stock offered hereby would represent an ownership interest in the Company as it
exists on the date hereof and not of the Company as combined with APC. In such
an event, the net proceeds of the Offering will be used for general corporate
purposes, which may include repayment of existing indebtedness, acquisitions or
capital expenditures. See "Risk Factors--Risks Associated with the Failure to
Complete the APC Acquisition."

- --------------------------
 
(1) Includes the results of operations of MSTI from the date of acquisition, May
    31, 1996.
 
(2) The unaudited pro forma as adjusted statement of operations data reflect:
    (i) the MSTI Acquisition (including related financing transactions); (ii)
    the APC Acquisition; (iii) the sale by the Company of 2,232,900 shares of
    Common Stock in June 1996 (the "1996 Offering") and the application of the
    proceeds therefrom; (iv) the refinancing of the Company's existing credit
    agreement (the "Existing Credit Agreement") and the redemption of the
    Company's senior notes (the "Senior Notes") in connection with the APC
    Acquisition; and (v) the Offering and the application of the net proceeds to
    the Company as described in "Use of Proceeds," as if such transactions had
    occurred on January 1, 1996. The Company acquired Trylon on January 16,
    1996. Results of operations of Trylon for the period January 1, 1996 through
    the acquisition date are not material and therefore have not been included
    in the Company's pro forma results of operations for the year ended December
    31, 1996. See "Use of Proceeds" and "Unaudited Pro Forma Financial
    Statements." Net income, net income applicable to common stockholders and
    net income per common and common equivalent share are presented before
    extraordinary loss on early extinguishment of debt.
 

(3) The Company has not declared or paid any cash dividends on its Common Stock
    in the past, currently intends to retain its earnings to support its growth
    strategy and does not anticipate paying dividends in the foreseeable future.
    See "Dividend Policy."

(4) "EBITDA" is operating income plus depreciation and amortization. EBITDA does
    not represent and should not be considered as an alternative to net income
    or cash flow from operations as determined by generally accepted accounting
    principles ("GAAP") and the Company's calculation thereof may not be
    comparable to that reported by other companies. The Company believes that it
    is widely accepted that EBITDA provides useful information regarding a
    company's ability to service and/or incur indebtedness. This belief is based
    on the Company's negotiations with its lenders who have indicated that the
    amount of indebtedness the Company will be permitted to incur will be based,
    in part, on the Company's EBITDA. EBITDA does not take into account the
    Company's working capital requirements, debt service requirements and other
    commitments and, accordingly, is not necessarily indicative of amounts that
    may be available for discretionary uses. Set forth below is a reconciliation
    of the Company's operating income, as reported, to EBITDA for the periods
    indicated:

(5) "North American content per vehicle" on an actual basis is the Company's
    revenues divided by total North American vehicle production, which is
    comprised of car and light truck production in the United States, Canada and
    Mexico, as estimated by the Company from industry sources. Pro forma as
    adjusted "North American content per vehicle" also includes the automotive
    revenues of APC (excluding APC's heavy truck revenues).

 

(6) The unaudited pro forma as adjusted balance sheet data reflect: (i) the APC
    Acquisition; (ii) the refinancing of the Company's Existing Credit Agreement
    and redemption of the Senior Notes; and (iii) the Offering and the
    application of the net proceeds to the Company as described in "Use of
    Proceeds," as if such transactions had occurred on December 31, 1996. See

FACTORS, SOME OF WHICH MAY BE BEYOND THE CONTROL OF THE COMPANY. THE COMPANY
CAUTIONS THE READER, HOWEVER, THAT THIS LIST OF FACTORS MAY NOT BE EXHAUSTIVE,
PARTICULARLY WITH RESPECT TO FUTURE FILINGS WITH THE COMMISSION. IN ANALYZING AN
INVESTMENT IN THE COMMON STOCK OFFERED HEREBY, PROSPECTIVE INVESTORS SHOULD
CAREFULLY CONSIDER, ALONG WITH THE OTHER MATTERS REFERRED TO HEREIN, THE RISK
FACTORS DESCRIBED BELOW.
 

RISKS ASSOCIATED WITH THE FAILURE TO COMPLETE THE APC ACQUISITION

 

    The Company expects to complete the APC Acquisition by the end of April
1997. Pursuant to the terms of the purchase agreement, the Company may elect not
to complete the APC Acquisition if there is a material adverse change in the
operating results or financial condition of APC prior to the closing date. There
can be no assurance that such a change will not occur or that, if such a change
were to occur, that the APC Acquisition would be completed. If the APC
Acquisition is not completed, the shares of Common Stock offered hereby would
represent an ownership interest in the Company as it exists on the date hereof
and not of the Company as combined with APC. Therefore, if the APC Acquisition
is not consummated, the information set forth in this Prospectus giving effect
to the APC Acquisition would not be relevant.

 

    Prior to the Offering, there were 14,340,800 shares of Common Stock
outstanding. Upon consummation of the Offering, there will be 22,840,800 shares
of Common Stock outstanding. If the APC Acquisition is not consummated, the size
of the Company will not increase, but the number of outstanding shares will
have, and thus the value of each share of the Common Stock would be
significantly diluted. The Company's net income per common and common equivalent
share before extraordinary item ("EPS") for 1996 on a pro forma as adjusted
basis would have been $2.25 per share. If the APC Acquisition is not completed,
the Company's EPS for 1996 on a pro forma as adjusted basis would have been
$1.17 per share. In addition, the net proceeds to the Company from the Offering
are expected to be used to pay a portion of the cash purchase price of the APC
Acquisition. In the event the APC Acquisition is not consummated, the Company
intends to use the net proceeds of the Offering for general corporate purposes,
which may include repayment of existing indebtedness, acquisitions or capital
expenditures.

 

    In connection with the APC Acquisition, the Company expects to enter into a
new credit agreement (the "New Credit Agreement") to finance a portion of the
APC Acquisition. The commitments of its bank lender under the New Credit
Agreement expire if the APC Acquisition is not consummated on or prior to April
30, 1997. If such commitments expire and are not renewed by such lender, the
Company would be required to seek alternative sources of financing. There can be
no assurance that the Company would be able to secure such alternative financing
or that such financing, if available, would be on terms acceptable to the
Company. If the Company does not consummate the APC Acquisition because it fails
to secure financing, the Company is required to pay A.O. Smith a fee of $15.0
million. In addition, if the APC Acquisition is not consummated by June 30,
1997, A.O. Smith's obligation to consummate the APC Acquisition will lapse and
there can be no assurance that the Company will be able to purchase APC on the
terms disclosed herein, on terms acceptable to the Company or at all.

 
                                       10
<PAGE>
RISKS ASSOCIATED WITH LEVERAGE
 

    The APC Acquisition will significantly increase the Company's debt service
obligations. As of December 31, 1996 on a pro forma basis, the Company would
have had total outstanding long-term indebtedness of approximately $405.8
million, or 44.8% of the Company's total capitalization. The degree to which the
Company is leveraged could make it more difficult for the Company to adjust to
rapidly changing market conditions and could make it more vulnerable in the
event of a downturn in general economic conditions or its business. See
"Description of New Credit Agreement."

 
RELIANCE ON MAJOR CUSTOMERS AND SELECTED MODELS
 

    Ford, Chrysler and General Motors accounted for approximately 67%, 10% and
4%, respectively, of the Company's revenues during 1996 and approximately 53%,
17% and 17%, respectively, on a pro forma basis. Although the Company and APC
have contracts with many of their customers, such contracts provide for
supplying the customers' requirements for a particular model, rather than for
manufacturing a specific quantity of products. The loss of any one of their
major customers or a significant decrease in demand for certain key models or a
group of related models sold by any of their major customers could have a
material adverse effect on the Company and APC. There is substantial and
continuing pressure from OEMs to reduce costs, including the cost of products
purchased from outside suppliers such as the Company and APC. Certain of the
Company's products are sold under long-term agreements that require the Company
to provide annual cost reductions to such purchasers (directly through price
reductions or indirectly through suggestions regarding manufacturing
efficiencies or other cost savings) by certain percentages each year. Although
the Company has been able to achieve a portion of such reductions through
production cost savings, there can be no assurance that the Company will be able
to continue to generate such cost savings in the future. If the Company were
unable to generate sufficient production cost savings in the future to offset
such price reductions, the Company's gross margin could be adversely affected.
See "Business--Customers and Marketing."

 

RISKS RELATED TO INDUSTRY CYCLICALITY AND SEASONALITY

 
    The automotive market is highly cyclical and is dependent on consumer
spending. Economic factors adversely affecting automotive production and
consumer spending could adversely impact the Company. In addition, the Company's
business is somewhat seasonal. The Company typically experiences decreased
revenue and operating income during the third quarter of each year due to the
impact of OEM plant shutdowns in July for vacations and model changeovers. The
Company expects such seasonality to continue following the APC Acquisition. See
"Management's Discussion and Analysis of Results of Operations and Financial
Condition--Seasonality."
 
FAILURE TO REALIZE BENEFITS OF APC ACQUISITION
 
    The Company believes the APC Acquisition will significantly enhance its
competitive position and business prospects. There can be no assurance, however,
that such benefits will be realized or that the combination of the Company and
APC will be successful. In addition, the Company expects to achieve cost savings
through the integration of the operations of APC with those of the Company.
There can be no assurance that the Company will not experience difficulties in
integrating the operations of APC with those of the Company or that the expected
cost savings will be realized. The integration of APC will require the
experience and expertise of certain key managers of APC who are expected to be
retained by the Company. There can be no assurance that the APC managers
retained by the Company will remain with the Company for the time period
necessary to successfully integrate APC into the Company.

RISKS ASSOCIATED WITH OBTAINING BUSINESS FOR NEW AND REDESIGNED MODEL
  INTRODUCTIONS

 

    The Company and APC principally compete for new business both at the
beginning of the development of new models and upon the redesign of existing
models by their major customers. New model development generally begins two to
five years prior to the marketing of such models to the public. There can be no
assurance that the Company and APC will be successful in obtaining significant
new business on new models and in supplying additional parts for existing models
as they are redesigned by their customers. The failure of the Company and APC to
obtain new business on new models or to retain or increase business on
redesigned existing models could adversely affect the Company. See "Business--
Competition."

 
RISKS ASSOCIATED WITH ACQUISITION STRATEGY
 

    Acquiring businesses that complement the Company's existing business has
been and will continue to be an important element of the Company's strategy for
achieving profitable growth. There can be no assurance that suitable acquisition
candidates will be identified and acquired in the future, that financing for any
such acquisitions will be available on satisfactory terms, that the Company will
be able to accomplish its strategic objectives as a result of any such
acquisition or that any business or assets acquired by the Company will be
integrated successfully into the Company's operations. The Company is
continually evaluating possible acquisitions and engages in discussions with
acquisition candidates from time to time. The Company does not currently have
any pending acquisitions that are probable other than as described herein. See
"Business--Strategy."

 

RISKS FROM COMPETITION

 

    The automotive components supply industry is highly competitive. Some of the
competitors of the Company and APC, including certain divisions of its OEM
customers, are larger and have greater financial and other resources than the
Company and APC. There can be no assurance that the Company will be able to
maintain its current competitive position and continue to supply its products to
OEMs. See "Business-- Competition."

 

ANTI-TAKEOVER PROVISIONS COULD PREVENT OR DELAY A CHANGE IN CONTROL

 
    Certain provisions of the Company's Amended and Restated Certificate of
Incorporation, which permit the Board of Directors to issue up to 5,000,000
shares of preferred stock without further stockholder approval, as well as
certain provisions of the Delaware General Corporation Law, could have the
effect of delaying, deterring or preventing a change in control of the Company.
 
POSSIBLE VOLATILITY OF STOCK PRICE
 
    The public offering price per share of the Common Stock has been determined
by negotiations among the Company and representatives of the Underwriters based
in part on the trading price of the Common Stock on the NYSE and may not be
indicative of the price at which the Common Stock will trade after completion of
the Offering. In addition, the stock markets have from time to time experienced
extreme price and volume volatility. These fluctuations may be unrelated to the
operating performance of particular companies whose shares are traded. Market
fluctuations may adversely affect the market price of the Common Stock. The
market price of the Common Stock could be subject to significant fluctuations in
response to the Company's operating results and other factors, some of which may
be beyond the Company's control. There can be no assurance that the market price
of the Common Stock will not decline below the price at which the shares of the
Common Stock are sold in this Offering.

<PAGE>
                                  THE COMPANY
 
    The Company was formed to acquire R.J. Tower Corporation (the
"Predecessor"), the acquisition of which was completed in April 1993 (the "R.J.
Tower Acquisition") for an aggregate cost of approximately $26 million. Since
the R.J. Tower Acquisition, the Company has successfully completed and fully
integrated four strategic acquisitions:
 
    EDGEWOOD.  In May 1994, the Company acquired Edgewood Tool and Manufacturing
Company and its affiliate, Ann Arbor Assembly Corporation (collectively,
"Edgewood") for approximately $30 million in aggregate consideration. Edgewood
is a leading supplier of hood and deck lid hinges as well as structural
stampings and assemblies. The acquisition of Edgewood: (i) added engineered
mechanical stampings, primarily hood and deck lid hinges, and additional
structural components to the Company's product offerings; (ii) increased model
penetration with the Company's existing customers; and (iii) provided the
Company with a significant new customer, Mazda.
 
    KALAMAZOO.  In June 1994, the Company acquired Kalamazoo Stamping and Die
Company ("Kalamazoo"), a supplier of structural stampings and assemblies, for
approximately $12 million in cash. The acquisition of Kalamazoo added additional
structural components to the Company's product offerings and increased model
penetration with Ford.
 
    TRYLON.  In January 1996, the Company acquired Trylon from MascoTech for
approximately $25 million in cash, including transaction costs. The Trylon
Acquisition: (i) broadened the Company's product offerings to include small,
precision metal stampings and assemblies, which were previously outsourced to
third parties; (ii) established a relationship between the Company and General
Motors; and (iii) increased content on Ford models, primarily the Villager.
Trylon generated $47.9 million in revenues in 1995.
 
    MSTI.  In May 1996, the Company acquired MSTI from MascoTech for
approximately $79 million (including the payment of related fees and expenses),
plus additional earn-out payments if certain operating targets are achieved by
the MSTI facilities in the first three years following the acquisition. The MSTI
Acquisition: (i) expanded the Company's product capabilities into chassis and
suspension components; (ii) provided chassis and suspension technology as well
as value-added processing technologies including assembling, painting and
welding; and (iii) increased the Company's content per vehicle on key light
truck and sport utility vehicles such as the Ford F-Series, Explorer and
Windstar and the Chrysler Ram and Dakota as well as on high volume passenger
cars such as the Ford Taurus/Sable. MSTI had revenues of $152.9 million in 1995.
 
    The Company completed an initial public offering (the "IPO") of its Common
Stock in August 1994 and the sale of an additional 2,232,900 shares in June
1996. The Company's principal executive offices are located at 4508 IDS Center,
Minneapolis, Minnesota 55402, and its telephone number is (612) 342-2310.
 
                           APC ACQUISITION FINANCING
 

    The Company expects to complete the APC Acquisition by the end of April
1997. The aggregate purchase price of APC is approximately $625 million, plus an
additional $25 million for related fees and expenses and management's estimate
of certain post-closing adjustments. The Company has executed a commitment
letter with its principal bank lender pursuant to which such lender has agreed,
subject to the satisfaction of certain conditions, to enter into the New Credit
Agreement. The Company anticipates that the New Credit Agreement will provide
for a six year revolving credit facility of up to $750 million (the "Revolving
Credit Facility.") The Company intends to finance the APC Acquisition by using
the proceeds from this Offering and a portion of its available borrowings under
the New Credit Agreement. In the event that the Offering has not been completed
at the time of the consummation of the APC Acquisition, an additional loan of up
to $200 million will be made available to the Company under the New Credit
Agreement in the form of a term loan. This loan would have a term of 18 months
and would be fully repaid from the proceeds of the Offering. See "Description of
New Credit Agreement."

    underwriting discounts and commissions and estimated offering expenses
    payable by the Company.

 
(2) Includes the redemption of the Senior Notes in aggregate principal amount of
    $65.0 million and a prepayment penalty of approximately $3.9 million. The
    Senior Notes were issued by the Company in May 1996 to finance the cash
    portion of the purchase price of MSTI.
 
                                USE OF PROCEEDS
 

    The net proceeds to be received by the Company from the sale of the
8,500,000 shares of Common Stock offered by the Company hereby (at an assumed
public offering price of $39.63 per share and after deducting the underwriting
discounts and commissions and estimated offering expenses payable by the
Company) are estimated to be $322.0 million ($379.6 million if the Underwriters'
over-allotment option is exercised in full). The Company expects to use the net
proceeds to pay a portion of the cash purchase price of the APC Acquisition. The
Company expects to use borrowings under the New Credit Agreement of $357.3
million, together with cash on hand of $39.6 million, to pay the remaining
portion of the purchase price of the APC Acquisition.

 

    In the event that the APC Acquisition is not consummated, the Company
reserves the right to use the net proceeds of the Offering for general corporate
purposes, which may include repayment of existing indebtedness, acquisitions or
capital expenditures. Pending such uses, the Company expects that such proceeds
will be invested in short-term, interest bearing, investment grade securities.
See "Risk Factors-- Risks Associated with the Failure to Complete the APC
Acquisition."

 

    The Company is continually evaluating possible acquisitions and engages in
discussions with acquisition candidates from time to time. The Company does not
currently have any pending acquisitions that are probable other than as
described herein.

 
    The Company will not receive any of the proceeds from the sale of Common
Stock by the Selling Stockholders. See "Selling Stockholders."

    The reported last sale price of the Common Stock on the NYSE as of a recent
date is set forth on the cover page of this Prospectus.

 
    As of December 31, 1996, there were approximately 125 holders of record of
the outstanding Common Stock. The Company believes it has a significantly larger
number of beneficial holders of its Common Stock.
 
                                DIVIDEND POLICY
 
    The Company has not declared or paid any cash dividends on its Common Stock
in the past, currently intends to retain its earnings to support its growth
strategy and does not anticipate paying dividends in the foreseeable future. Any
future payment of dividends is within the discretion of the Company's Board of
Directors and will depend upon, among other factors, the capital requirements,
operating results and financial condition of the Company from time to time. In
addition, the Company's ability to pay cash dividends is expected to be limited
by the terms of the New Credit Agreement. As of December 31, 1996, under the
most restrictive terms of the New Credit Agreement as currently proposed, the
Company would not have been permitted to pay any dividends. See "Management's
Discussion and Analysis of Results of Operations and Financial
Condition--Liquidity and Capital Resources Following the APC Acquisition."

                    UNAUDITED PRO FORMA FINANCIAL STATEMENTS
 

    The following Unaudited Pro Forma Statement of Operations for the year ended
December 31, 1996 gives effect to: (i) the MSTI Acquisition (including related
financing transactions); (ii) the 1996 Offering and the application of the net
proceeds therefrom; (iii) the APC Acquisition; (iv) the refinancing of the
Existing Credit Agreement and redemption of the Senior Notes; and (v) the
Offering and the application of the net proceeds therefrom to the Company as
described in "Use of Proceeds," as if such transactions had occurred on January
1, 1996. The Company acquired Trylon on January 16, 1996. Results of operations
of Trylon for the period from January 1, 1996 through the acquisition date are
not material and therefore have not been included in the Company's results of
operations for the year ended December 31, 1996 on a pro forma basis. See "The
Company" and "Use of Proceeds" on pages 13 and 14, respectively, for a more
detailed description of the transactions included in the Unaudited Pro Forma
Financial Statements.

 
    The information set forth under the heading Pro Forma As Adjusted included
in the Unaudited Pro Forma Balance Sheet as of December 31, 1996 reflects: (i)
the APC Acquisition; (ii) the refinancing of the Existing Credit Agreement and
redemption of the Senior Notes; and (iii) the Offering and the application of
the net proceeds therefrom to the Company as described under "Use of Proceeds,"
as if such transactions had occurred on such date. The historical balance sheet
of the Company as of December 31, 1996 already reflects the Trylon Acquisition,
the MSTI Acquisition and the 1996 Offering.
 
    The Company expects to achieve cost savings through the integration of the
operations of APC with those of the Company. See "Business--APC Acquisition."
The Unaudited Pro Forma Financial Statements set forth herein do not reflect any
of these anticipated cost savings.
 

    The Company expects to complete the APC Acquisition by the end of April
1997. Pursuant to the terms of the purchase agreement, the Company may elect not
to complete the APC Acquisition if there is a material adverse change in the
operating results or financial condition of APC prior to the closing date.
Currently, the Company believes that such a change has not occurred and that it
is unlikely that such a change will occur prior to the closing date. If the APC
Acquisition is not consummated, the size of the Company will not increase, but
the number of outstanding shares will have, and thus the value of each share of
Common Stock would be significantly diluted. The Company's EPS for 1996 on a pro
forma as adjusted basis would have been $2.25 per share. If the APC Acquisition
is not completed, the Company's EPS for 1996 on a pro forma as adjusted basis
would have been $1.17 per share. See "Risk Factors--Risks Associated with the
Failure to Complete the APC Acquisition." The Company is required to pay A.O.
Smith a fee of $15.0 million in the event that the APC Acquisition is not
completed. The Company currently believes that the APC Acquisition will be
completed. As a result, the Company has not reflected this payment in the
accompanying Unaudited Pro Forma Financial Statements.

 
    The unaudited pro forma financial data presented herein are based on the
assumptions and adjustments described in the accompanying notes. The Unaudited
Pro Forma Statement of Operations does not purport to represent what the
Company's results of operations actually would have been if the events described
above had occurred as of the dates indicated or what such results will be for
any future periods. The Unaudited Pro Forma Financial Statements are based upon
assumptions and adjustments that the Company believes are reasonable. The
Unaudited Pro Forma Financial Statements and the accompanying notes should be
read in conjunction with the historical financial statements of the Company and
of APC, including the notes thereto, included elsewhere in this Prospectus.
 

    Each of the acquisitions referred to in these Unaudited Pro Forma Financial
Statements have been or will be accounted for using the purchase method of
accounting and, accordingly, the assets acquired and liabilities assumed have
been or will be recorded at their fair values as of the dates of their
respective acquisitions. These amounts have been recorded based upon preliminary
estimates as of the dates of the acquisitions. The Company does not believe that
any changes to these estimates that may occur will have a material impact on the
pro forma financial information included herein.

              NOTES TO UNAUDITED PRO FORMA STATEMENT OF OPERATIONS
                             (DOLLARS IN THOUSANDS)
 
 (1) Represents the results of operations of the Company for the year ended
    December 31, 1996 and the results of operations of Trylon and MSTI from the
    dates of their respective acquisitions.
 
 (2) Represents the results of operations for MSTI from January 1, 1996 through
    the date of acquisition, May 31, 1996.
 
 (3) Represents the results of operations for APC for the year ended December
    31, 1996.
 
 (4) To eliminate sales of stampings from the Company to APC during 1996.
 
 (5) To eliminate purchases made by APC from the Company during 1996 of $13,600
    (See Note 4) and to reflect the change in depreciation expense resulting
    from adjustments to the depreciable lives of property, plant and equipment
    of MSTI and APC to their estimated useful lives at the time of their
    acquisition and from adjustments to value such property, plant and equipment
    at fair value as of the dates of acquisition ($17,862).
 
 (6) Represents the amortization of goodwill arising from the acquisition of
    MSTI ($415) and APC ($4,633), net of amortization of goodwill previously
    recorded by MSTI ($683) which has been eliminated. Goodwill will be
    amortized on a straight-line basis over a forty-year period.
 

 (7) Represents incremental interest expense arising from indebtedness incurred
    in connection with the acquisitions of MSTI ($2,314) and APC ($40,069), net
    of the reduction in interest expense which results from the application of
    the proceeds from the 1996 Offering ($993) and the Offering ($26,750).
    Adjustments to interest expense have been calculated based on an assumed
    weighted average borrowing rate of 6.75% during the pro forma period. If the
    assumed interest rate were to change by 1/8 of 1%, interest expense would
    change by approximately $440 and net income would change by approximately
    $265.

 
 (8) To adjust the provision for income taxes on a pro forma basis to reflect
    the Company's incremental tax rate of 40%.
 
 (9) Represents the payment of a prepayment penalty of $3,900 on the redemption
    of the Senior Notes and the write-off of $1,100 of related deferred
    financing costs, net of the related income tax effect of $2,000.
 
(10) Represents the pro forma effect from the shares issued to MascoTech in
    connection with the MSTI Acquisition, the 2,232,900 shares issued in the
    1996 Offering, including shares issued upon the exercise of the
    underwriters' over-allotment option, and the issuance of 8,500,000 shares of
    the Common Stock in the Offering.

  goodwill........................................................    185,326
                                                                    ---------
  Total purchase price allocated..................................  $ 650,000

</TABLE>

 

(2) To record inventories at estimated fair value, including the elimination of
    APC's historical LIFO reserve.

 

(3) To write off APC's historical deferred tax benefit.

 

(4) To state property, plant and equipment acquired in the APC Acquisition at
    estimated fair value and eliminate historical accumulated depreciation.

 

(5) To adjust goodwill to the amount recognized in connection with the APC
    Acquisition. The goodwill will be amortized on a straight-line basis over a
    forty-year period.

 

(6) To reflect the financing transactions related to the APC Acquisition and the
    application of the net proceeds to the Company of the Offering. Upon the
    consummation of the APC Acquisition, the Company intends to refinance the
    Existing Credit Agreement and retire certain other indebtedness with
    borrowings under the New Credit Agreement. See "Description of New Credit
    Agreement" for a detailed description of the terms of the New Credit
    Agreement. In connection with the retirement of certain indebtedness, the
    Company will write-off $1,100 of previously capitalized deferred financing
    costs and expects to pay a prepayment penalty of $3,900 on the redemption of
    the Senior Notes. This will result in a reduction in current income taxes
    payable of $2,000 and an extraordinary loss, net of income taxes, of $3,000.

 
    The following table sets forth the sources and uses of funds in the APC
    Acquisition:

(7) To write off historical deferred taxes of $35,700 and to record management's
    preliminary estimate of reserves to be established in connection with the
    APC Acquisition, including $15,500 of losses to be incurred on the sale of
    products which have costs in excess of selling prices and $4,500 of costs to
    be incurred to rationalize certain facilities of APC. These reserves have
    been established based on preliminary estimates.

(1) On April 15, 1993, the Company acquired the Predecessor. Accordingly,
    certain information provided for the year ended December 31, 1992, and the
    three and one-half month period ended April 14, 1993, is not comparable to
    the Statement of Operations Data of the Company due to the effects of
    certain purchase accounting adjustments and the financing of the R.J. Tower
    Acquisition. See "Management's Discussion and Analysis of Results of
    Operations and Financial Condition."
 
(2) Operating data for the Predecessor for the period January 1, 1993 to April
    14, 1993 have been combined for presentation purposes with the operating
    data of the Company for the eight and one-half month period ended December
    31, 1993, without giving effect to purchase accounting or the impact of the
    financing of the R.J. Tower Acquisition.
 
(3) Includes the results of operations of MSTI from the date of acquisition, May
    31, 1996.
 

(4) The Company has not declared or paid any cash dividends on its Common Stock
    in the past, currently intends to retain its earnings to support its growth
    strategy and does not anticipate paying dividends in the foreseeable future.
    See "Dividend Policy."

 

(5) "EBITDA" is operating income plus amortization and depreciation. EBITDA does
    not represent and should not be considered an alternative to net income or
    cash flow from operations as determined by GAAP and the Company's
    calculation thereof may not be comparable to that reported by other
    companies. The Company believes that it is widely accepted that EBITDA
    provides useful information regarding a company's ability to service and/or
    incur indebtedness. This belief is based on the Company's negotiations with
    its lenders who have indicated that the amount of indebtedness the Company
    will be permitted to incur will be based, in part, on the Company's EBITDA.
    EBITDA does not take into account the Company's working capital
    requirements, debt service requirements and other commitments and,
    accordingly, is not necessarily indicative of amounts that may be available
    for discretionary uses. Set forth below is a reconciliation of the Company's
    operating income, as reported, to EBITDA for the periods indicated:

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 RESULTS OF OPERATIONS AND FINANCIAL CONDITION
 
GENERAL
 

    The Company was organized to effect the R.J. Tower Acquisition, which was
financed with a combination of common equity and secured indebtedness. Since the
R.J. Tower Acquisition, the Company has successfully completed and fully
integrated four strategic acquisitions. See "The Company." The Company expects
to complete the APC Acquisition by the end of April 1997. No assurance can be
given, however, that the APC Acquisition will be completed. See "Risk
Factors--Risks Associated with the Failure to Complete the APC Acquisition."

 
    The Company's four previous acquisitions have affected, and the APC
Acquisition will prospectively affect, the Company's results of operations in
certain significant respects. As a result of the APC Acquisition, the Company
will increase the historical book value of APC's assets, including intangible
assets such as goodwill, which will significantly increase the amount of
amortization expense reported in the Company's ongoing operations. In addition,
the Company's interest expense will increase significantly due to increased
borrowings to finance the APC Acquisition. The Company expects to achieve cost
savings through the integration of the operations of APC with those of the
Company.
 
    The Company believes that its overall gross margin has been slightly higher
than that of APC, primarily because the Company has historically sold a greater
percentage of complex, high value-added products than APC. In addition, APC's
overall gross margin has been negatively impacted in recent years as a result of
APC's beginning production of certain products that require a greater proportion
of components purchased from outside suppliers and higher launch costs and
depreciation expense related to the new production. The Company expects that, as
a result of the APC Acquisition, its overall gross margin will be lower in
future periods.

COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995
 
    REVENUES.  Revenues for the year ended December 31, 1996 increased by $177.1
million, or 79.5%, to $399.9 million compared to $222.8 million for the year
ended December 31, 1995. Approximately $134.3 million of the increase in
revenues over 1995 is attributable to the acquisitions of MSTI in May 1996 and
Trylon in January 1996. The remaining increase is due to new business awarded to
the Company, including
 
                                       25
<PAGE>
business relating to the Ford Escort, Econoline and Expedition, Dodge Ram Club
Cab pick-up and Toyota Camry. These increases were partially offset by
production decreases in the first half of the year on key models served by the
Company, including the Ford Aerostar, Villager, Econoline and Chrysler Intrepid/
Concorde/Vision.
 
    COST OF SALES.  Cost of sales as a percentage of revenues for the year ended
December 31, 1996 was 84.6% compared to 83.2% for the year ended December 31,
1995. The decrease in gross margin was due to a higher proportion of components
purchased from outside suppliers as a result of the Trylon and MSTI Acquisitions
and launch costs associated with new business. These decreases were partially
offset by operating efficiencies and enhanced productivity.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased to $20.0 million, or 5.0% of revenues, for the
year ended December 31, 1996 compared to $14.3 million, or 6.4% of revenues, for
the year ended December 31, 1995. The percentage decrease related to revenues
reflects the economies of scale of higher gross sales. The increased expense was
due primarily to incremental costs associated with the Company's acquisitions of
MSTI and Trylon in 1996.
 
    AMORTIZATION EXPENSE.  Amortization expense for the year ended December 31,
1996 was $2.2 million compared to $1.2 million for the year ended December 31,
1995. The increase was due to incremental goodwill amortization related to the
acquisitions of MSTI and Trylon.
 
    INTEREST EXPENSE.  Interest expense for the year ended December 31, 1996 was
$5.1 million compared to $1.8 million for the year ended December 31, 1995. The
increase was due principally to increased borrowings incurred to fund the
acquisitions of MSTI and Trylon, partially offset by the application of the
proceeds from the 1996 Offering, and the absence of capitalization of interest
costs for the new Bardstown, Kentucky plant which was under construction during
1995.
 
    INCOME TAXES.  The effective income tax rate was 39.9% for the year ended
December 31, 1996 and 40.0% for the year ended December 31, 1995. The effective
rates differed from the statutory rates primarily as a result of state taxes and
nondeductible goodwill amortization.
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994
 

    REVENUES.  Revenues for the year ended December 31, 1995 increased $57.3
million, or 34.6%, to $222.8 million compared to $165.5 million for the year
ended December 31, 1994. Revenues increased despite significant production
decreases on key vehicles served by the Company including the Ford Escort,
Taurus/Sable, and Econoline and Chrysler Intrepid/Concorde/Vision. These
decreases were offset by new business that began production during the year and
the full year effects of the Company's acquisitions of Edgewood in May 1994 and
Kalamazoo in June 1994.

 
    COST OF SALES.  Cost of sales, as a percentage of revenues, decreased to
83.2% for the year ended December 31, 1995 compared to 86.4% for the year ended
December 31, 1994. The improvement in gross margin was a result of the
productivity improvement initiatives in place and synergies realized from the
acquisitions of Edgewood and Kalamazoo. These were partially offset by higher
raw material costs.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses increased to $14.3 million, or 6.4% of revenues, for the
year ended December 31, 1995 compared to $7.4 million, or 4.5% of revenues, for
the year ended December 31, 1994. The increased expense was due in part to the
full year effect of the acquisitions of Edgewood and Kalamazoo combined with the
incremental engineering, technical and development costs associated with future
programs.
 
    OTHER.  Amortization expense increased to $1.2 million for the year ended
December 31, 1995 from $0.8 million for the year ended December 31, 1994 due to
incremental goodwill amortization related to the Company's 1994 acquisitions.
Interest expense decreased to $1.8 million in 1995 from $1.9 million in 1994.
 
                                       26
<PAGE>

The decrease is due to the effect of the application of the proceeds from the
Company's IPO to reduce indebtedness. The provision for income taxes was at an
effective rate of 40.0% for the year ended December 31, 1995 and 40.7% for the
year ended December 31, 1994. The effective rates were higher than federal
statutory rates as a result of nondeductible goodwill amortization and state
income taxes.

</TABLE>
 
COMPARISON OF YEAR ENDED DECEMBER 31, 1996 TO YEAR ENDED DECEMBER 31, 1995
 
    REVENUES.  Revenues for the year ended December 31, 1996 increased $17.7
million, or 2.1%, to $863.0 million compared to $845.3 million for the year
ended December 31, 1995. This increase in revenue is attributable to new
business associated with the redesigned Nissan pick-up and the effects of the
full year's production of the Dodge Ram Club Cab pick-up, as well as overall
production increases on key vehicles served by APC, including the Ford
Taurus/Sable and the General Motors Yukon/Chevrolet Tahoe. These increases were
partially offset by lower production of the Dodge Dakota pick-up as a result of
the launch of a redesigned version of this vehicle during 1996.
 
    COST OF SALES.  Cost of sales, as a percentage of revenues, was 89.2% for
the year ended December 31, 1996, compared to 88.7% for the year ended December
31, 1995. APC's gross margin was negatively impacted by higher incremental costs
associated with the launch of new products during 1996, along with relative
increases in depreciation expense associated with capital equipment placed in
service during 1995 and 1996 related to this new business. These increases were
partially offset by improved labor efficiencies and productivity.
 

    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses were $37.2 million, or 4.3% of revenues, for the year
ended December 31, 1996 compared to $37.4 million for the prior year, a decrease
of approximately 0.5%. These costs include incremental design and engineering
expenditures associated with new business to be introduced in future periods,
including the Ford Ranger, which was launched late in 1996, the Dodge Durango,
Chrysler's entry into the sport utility market, and the front and rear
suspension modules for the Chrysler Intrepid/Concorde/Vision. These incremental
costs were offset by lower overall general and administrative costs.

 
COMPARISON OF YEAR ENDED DECEMBER 31, 1995 TO YEAR ENDED DECEMBER 31, 1994
 
    REVENUES.  Revenues for the year ended December 31, 1995 increased $122.6
million, or 17.0%, to $845.3 million compared to $722.7 million for the year
ended December 31, 1994. This increase was attributable to new business
associated with the launches of the redesigned Ford Explorer and General Motors
Yukon/Chevrolet Tahoe, as well as the effect of the full year's production of
the Ford Contour/ Mercury Mystique, which was launched during 1994.
 
                                       27
<PAGE>
    COST OF SALES.  Cost of sales, as a percentage of revenues, was 88.7% for
the year ended December 31, 1995, compared to 86.4% for the year ended December
31, 1994. Higher costs associated with the launch of new products during 1995
contributed to the overall increase in these costs. In addition, APC also
experienced higher relative labor costs as a result of the increase in overall
product demand during 1995. Higher depreciation expense associated with capital
equipment used in the production of new products launched during 1994 and 1995
also contributed to these higher costs. Gross margin was also negatively
impacted as a result of APC's beginning production of certain products that
require a greater proportion of components purchased from outside suppliers.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  Selling, general and
administrative expenses were $37.4 million, or 4.5% of revenues, for the year
ended December 31, 1995 compared to $34.0 million, or 4.7% of revenues, for the
prior year, an increase of approximately 10.0%. Higher design and engineering
costs associated with products to be launched in future periods, including the
redesigned Ford Ranger and Dodge Dakota pick-ups, contributed to this increase.
In addition, selling and general administrative costs increased to support the
overall higher revenues in 1995 compared to 1994.
 
SEASONALITY
 
    The Company's performance is dependent on automotive vehicle production,
which is seasonal in nature. The third calendar quarter is historically the
weakest, due to the impact of OEM plant shutdowns in July for vacation and model
changeovers. Additionally, general industry levels are only a partial
explanation of volume changes throughout the year. Individual vehicle platforms
are also a cause of variations in revenues depending upon market response and
acceptance of the specific platform models.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    At December 31, 1996, the Company had no indebtedness outstanding under the
revolving credit facility portion of its Existing Credit Agreement. The Existing
Credit Agreement consists of a revolving credit facility with a committed amount
of $75.0 million (subject to eligible accounts receivable and inventory, as
defined in the Existing Credit Agreement, which exceeded $75.0 million at
December 31, 1996). The Existing Credit Agreement matures in January 2001 and
bears interest at variable rates equal to, at the Company's option, either a
prime-based rate or LIBOR plus a variable margin. The Existing Credit Agreement
provides for the issuance of up to $50 million in letters of credit to
collateralize the outstanding IRBs described below.
 
    At December 31, 1996, the Company also had $43.8 million of indebtedness
outstanding pursuant to IRBs issued with the City of Bardstown, Kentucky.
Proceeds from these IRBs were used to finance construction of a 240,000 square
foot manufacturing facility and the related purchase of equipment. The Bardstown
IRBs, which mature on June 1, 2024 and March 1, 2025, are collateralized by a
letter of credit. As of December 31, 1996, $34.2 million of the proceeds had
been expended or committed for the first phase of the facility and related
equipment. The unexpended proceeds from the Bardstown IRBs of $10.8 million at
December 31, 1996, are invested in treasury securities and will be used to
finance the second phase of the facility. These IRBs bear interest at a floating
rate which is adjusted weekly as determined by the bond remarketing agent (5.8%
at December 31, 1996). The second phase of the facility, which includes the
purchase and installation of additional processing equipment, is anticipated to
be completed by the end of 1998.
 
    At December 31, 1996, the Company had $2.9 million in outstanding
indebtedness relating to IRBs issued in connection with the construction of its
Auburn, Indiana plant. The Auburn IRBs are collateralized by a letter of credit,
certain equipment and a mortgage on the Company's Auburn, Indiana plant. The
Auburn IRBs are payable in annual installments of $720,000 through September
2000 and bear interest at a floating rate which is adjusted weekly as determined
by the bond remarketing agent (4.4% at December 31, 1996).
 
                                       28
<PAGE>
    On January 16, 1996, the Company acquired all of the outstanding common
stock of Trylon for total cash consideration of approximately $25 million, which
included transaction costs. To finance the acquisition, the Company incurred a
$25.0 million term loan, which was repaid in May 1996 using a portion of the
proceeds from the sale of the Senior Notes and borrowings under the Existing
Credit Agreement.
 

    On May 31, 1996, the Company purchased all of the outstanding common stock
of MSTI from MascoTech for an aggregate purchase price of approximately $79
million, including payment of related fees and expenses. Pursuant to the terms
of the acquisition, the Company is required to make additional earn-out payments
to MascoTech if certain operating targets are achieved by the MSTI facilities in
the first three years following the acquisition. If all such operating targets
are met, the total payments will not exceed $30.0 million.

 
    The Company financed the cash portion of the purchase price of MSTI through
the issuance in two series of Senior Notes having an aggregate principal amount
of $65.0 million. The $40.0 million of Series A Senior Notes have a final
maturity on June 1, 2006 and require annual principal payments commencing on
June 1, 2000 and continuing every year thereafter until their final maturity.
The $25.0 million of Series B Senior Notes have a final maturity on June 1, 2008
and require annual principal payments commencing on June 1, 2004 and continuing
every year thereafter until their final maturity. The Senior Notes require the
Company to make semi-annual interest payments commencing December 1, 1996. Net
proceeds from the sale of the Senior Notes in excess of the amounts used to
finance the cash portion of the MSTI Acquisition were used, together with
borrowings under the revolving credit facility, to repay in full the remaining
balance outstanding on the $25.0 million term loan incurred by the Company in
connection with the Trylon Acquisition.
 
    In June 1996, the Company completed an offering of 2,232,900 shares of
Common Stock at an offering price of $24.50 per share. Approximately $32 million
of the net proceeds from the 1996 Offering were used by the Company to retire
borrowings under its Existing Credit Agreement. The remaining proceeds are
included in cash and cash equivalents in the December 31, 1996 consolidated
balance sheet and will be used for other general corporate purposes, which may
include prepayment of other indebtedness, acquisitions or capital expenditures.
 
    During the year ended December 31, 1996, the Company generated $30.0 million
of cash from operations, which was partially used to fund capital expenditures.
 
    The Company has made substantial investments in manufacturing technology and
product design capability to support its products. The Company made capital
expenditures of approximately $16.3 million for the year ended December 31,
1996, primarily for equipment and dedicated tooling purchases related to new or
replacement programs.
 
LIQUIDITY AND CAPITAL RESOURCES FOLLOWING THE APC ACQUISITION
 
    The aggregate purchase price of the APC Acquisition is approximately $625
million, plus an additional $25 million for related fees and expenses and
management's estimates of certain post-closing adjustments. The Company expects
to complete the APC Acquisition by the end of April 1997. This acquisition will
be accounted for as a purchase and, accordingly, APC's assets and liabilities
will be recorded at fair value as of the acquisition date, with any excess
purchase price recorded as goodwill.
 

    In connection with the APC Acquisition, the Company expects to enter into
the New Credit Agreement. The New Credit Agreement will provide for borrowings
under the Revolving Credit Facility of up to $750 million over six years. In
addition, a term loan facility with up to $200 million in borrowings, payable
within 18 months, will be made available in the event the APC Acquisition is
completed prior to the completion of the Offering. Interest will be payable on
borrowings under the New Credit Agreement at the bank's Base Rate or the reserve
adjusted LIBOR Rate plus a margin ranging from 17 to 50 basis points, depending
upon the ratio of the consolidated indebtedness of the Company to stockholders'

 
                                       29
<PAGE>

investment. The New Credit Agreement will also include certain restrictive
covenants, which the Company expects will be similar in nature to those in the
Existing Credit Agreement. The New Credit Agreement will become effective
contemporaneously with the completion of the APC Acquisition.

 
    Proceeds from borrowings under the New Credit Agreement will be used to: (i)
finance the APC Acquisition; (ii) refinance existing indebtedness of the
Company, including the redemption of the Senior Notes; and (iii) pay transaction
fees and expenses associated with the APC Acquisition. In connection with the
redemption of the Senior Notes, the Company will record an extraordinary loss of
approximately $3.0 million, net of income taxes, related to prepayment penalties
and the write-off of previously capitalized deferred financing costs.
 
    Proceeds from this Offering will be used to fund a portion of the purchase
price related to the APC Acquisition or to repay indebtedness incurred under the
New Credit Agreement in the event that the APC Acquisition is consummated prior
to the completion of the Offering.
 
    APC's capital expenditures for the year ended December 31, 1996 were
approximately $152 million, of which approximately $63 million was used to
finance the construction and to purchase equipment for its new Plymouth,
Michigan and Roanoke, Virginia manufacturing facilities. APC's remaining capital
expenditures were used primarily to purchase equipment and dedicated tooling
related to new or replacement programs. The Company's capital expenditures for
the year ended December 31, 1996 on a pro forma basis were approximately $168
million. After completing the APC Acquisition, the Company expects its budget
for capital expenditures during the remainder of 1997 to be approximately $75
million. Capital expenditures in 1997 are expected to be financed either with
cash generated from operations or borrowings under the New Credit Agreement.
 
    The Company believes the borrowing availability under the New Credit
Agreement, together with funds generated by operations, should provide the
Company with the liquidity and capital resources to pursue its business strategy
through 1997, with respect to working capital, capital expenditures and other
operating needs. Under present conditions, management does not believe access to
funds will restrict its ability to pursue its acquisition strategy.
 
EFFECTS OF INFLATION
 
    Inflation generally affects the Company by increasing the interest expense
of floating rate indebtedness and by increasing the cost of labor, equipment and
raw materials. Management believes that inflation has not significantly impacted
the Company's business over the past 12 months. However, because selling prices
generally cannot be increased until a model changeover, the effects of inflation
must be offset by productivity improvements and volume from new business awards.

GENERAL
 

    The Company is a leading designer and producer of high-quality body
structure components and assemblies used by the major North American automotive
OEMs, Ford, Chrysler and General Motors, and certain Transplants, including
Honda, Toyota, Nissan and Mazda. The Company's current products range from large
structural stampings and assemblies, such as body pillars, chassis, suspension
and floor pan components and major housing assemblies, to engineered assemblies,
such as hood and deck lid hinges and brake components. On January 27, 1997, the
Company agreed to acquire A.O. Smith's APC division, a leading manufacturer of
light truck frames, automotive engine cradles and other structural and
suspension components, assemblies and modules used by major North American OEMs
and Transplants. Following the APC Acquisition, the Company believes it will be
one of the largest independent suppliers of structural components and assemblies
to the North American automotive market (based on net sales).

 

    Since its inception in April 1993, the Company's revenues have grown rapidly
through a focused strategy of internal growth and a highly disciplined
acquisition program. During the last three years, the Company has successfully
completed and fully integrated four acquisitions. As a result of such
acquisitions and internal growth, the Company's revenues have increased from $86
million in 1993 to approximately $474 million in 1996 (pro forma only for the
MSTI Acquisition), representing a compound annual growth rate of approximately
76%. The Company's North American content per vehicle has increased from $6.23
in 1993 to $26.74 in 1996 on an actual basis. The APC Acquisition will be the
Company's largest acquisition to date and will increase the Company's pro forma
revenues to approximately $1.3 billion and its pro forma North American content
per vehicle to $77.49 for 1996.

 
INDUSTRY TRENDS
 
    The Company's performance and growth is directly related to certain trends
within the automotive market, including the consolidation of the component
supply industry, the increase in global sourcing and the growth of
system/modular sourcing.
 
    SUPPLIER CONSOLIDATION.  The automotive supply industry has recently begun
to undergo significant consolidation. To lower costs and improve quality, OEMs
are reducing their supplier base by awarding sole-source contracts to
full-service suppliers who are able to supply larger segments of a vehicle.
OEMs' criteria for supplier selection include not only cost, quality and
responsiveness, but also full-service design, engineering and program management
capabilities. For full-service suppliers such as the Company, the new
environment provides an opportunity to grow by obtaining business previously
provided by other non-full service suppliers and by acquiring suppliers that
further enhance product, manufacturing and service capabilities. OEMs rigorously
evaluate suppliers on the basis of product quality, cost control, reliability of
delivery, product design capability, financial strength, new technology
implementation, quality and condition of facilities and overall management.
Suppliers that obtain superior ratings are considered for sourcing new business.
Although these new supplier policies have already resulted in significant
consolidation of component suppliers in certain segments, the Company believes
that consolidation within the
 
                                       31
<PAGE>
structural and suspension component segments of the automotive industry will
continue to provide attractive opportunities to acquire high-quality companies
that complement its existing business.
 
    GLOBAL SOURCING.  Regions such as Asia, Latin America, Mexico and Eastern
Europe are expected to experience significant growth in vehicle demand over the
next ten years. OEMs are positioning themselves to reach these emerging markets
in a cost-effective manner by seeking to design and produce "world cars" which
can be designed in one vehicle center to a single global standard but produced
and sold in different geographic markets, thereby allowing OEMs to reduce design
costs, take advantage of low-cost manufacturing locations and improve product
quality and consistency. OEMs increasingly are requiring their suppliers to have
the capability to design and manufacture their products in multiple geographic
markets.
 
    SYSTEM/MODULAR SOURCING.  OEMs are increasingly seeking suppliers capable of
providing complete systems or modules rather than suppliers who only provide
separate component parts. A system is a group of component parts which operate
together to provide a specific engineering driven functionality whereas a module
is a group of systems and/or component parts which are assembled and shipped to
the OEM for installation in a vehicle as a unit. By outsourcing complete systems
or modules, OEMs are able to reduce their costs associated with the design and
integration of different components and improve quality by enabling their
suppliers to assemble and test major portions of the vehicle prior to beginning
production. As a result of the APC Acquisition, the Company will be in an
improved position to capitalize on this trend by designing its products to
function together and by providing designs that are integrated into the design
of the entire vehicle.
 
STRATEGY
 

    The Company's business objective is to capitalize upon the consolidation,
globalization and system/ modular sourcing trends in the automotive supply
industry in order to be the leading provider of structural and suspension
components to OEMs on a worldwide basis. Key elements of the Company's operating
and growth strategies are outlined below:

 
OPERATING STRATEGY
 
    FULL-SERVICE TECHNICAL DESIGN, ENGINEERING AND PROGRAM MANAGEMENT
CAPABILITIES.  The Company strives to maintain a competitive advantage through
investment in research and product development, advanced engineering and program
management. The Company works with OEMs throughout the product development
process from concept vehicle and prototype development through the design and
implementation of manufacturing processes to provide full-service capabilities
to its customers. In some cases, the Company places design engineers at customer
facilities to coordinate its product design efforts with those of its OEM
customers.
 
    EFFICIENT MANUFACTURING/CONTINUOUS IMPROVEMENT PROGRAMS.  In response to
OEMs' increasingly stringent demands, the Company has implemented manufacturing
practices designed to maximize product quality and timeliness of delivery and
eliminate waste and inefficiency. The Company has continued to upgrade its
manufacturing equipment and processes through substantial investment in new
equipment, maintenance of existing equipment and utilization of manufacturing
engineering personnel.
 
    GLOBAL PRESENCE.  The Company strives to offer manufacturing and support
services to its customers on a global basis through a combination of
international wholly owned facilities and by entering into joint ventures and
partnerships with foreign suppliers. Since 1993, in furtherance of its global
expansion strategy, the Company has opened a European sales and engineering
office to service U.K. and German OEM customers and has established an
industrial partnership with The Kirchhoff Group ("Kirchhoff") in Germany. With
the APC Acquisition, the Company will further expand its ability to service OEMs
on a global basis. The Company also has relocated certain technical personnel
resources to locations where OEMs are developing "world cars."
 
                                       32
<PAGE>
    DECENTRALIZED, PARTICIPATIVE CULTURE.  The Company's decentralized approach
to managing its manufacturing facilities encourages decision making and employee
participation in areas such as manufacturing processes and customer service. The
Company's management team meets frequently at various Company locations in order
to maintain a unified Company culture. To increase employee productivity, the
Company utilizes incentive programs for all salaried and hourly employees and
provides incentives for employees who take advantage of its continuous
improvement programs and who provide cost savings ideas.
 
GROWTH STRATEGY
 
    STRATEGIC ACQUISITIONS.  The Company continues to believe that consolidation
in the automotive supply industry will provide further attractive opportunities
to acquire high-quality companies that complement its existing business. The
Company seeks to make acquisitions that (i) provide additional product,
manufacturing and technical capabilities; (ii) broaden the Company's geographic
coverage domestically and strengthen its ability to supply products on a global
basis; (iii) increase the number of models for which the Company supplies
products and the content supplied for existing models; and (iv) add new
customers. With the consummation of the APC Acquisition, the Company will have
acquired five businesses since 1993. The Company intends to seek future
acquisitions or develop strategic alliances that will strengthen the Company's
ability to supply its products on a global basis.
 
    MODULAR PRODUCT OPPORTUNITIES.  The Company has capitalized on the
system/modular sourcing trend among OEMs by offering customers higher
value-added supply capabilities through an increasing focus on the production of
assemblies consisting of multiple component parts that are welded or otherwise
fastened together by the Company. The APC Acquisition will significantly expand
the Company's ability to supply OEMs with modules consisting of integrated
assemblies and component parts that can be installed as a unit in a vehicle at
the OEM assembly plant.
 
    INCREASE VEHICLE PENETRATION.  The Company has developed strong
relationships with certain OEM engineering and purchasing personnel which allow
it to identify business opportunities and to react to customer needs in the
early stages of vehicle design. The Company believes that these relationships
give it a competitive advantage over smaller and less capable suppliers in
marketing its broad range of products and in developing new product concepts,
such as expanded use of modules, that complement its existing product lines.
 
    PURSUIT OF "WORLD CAR" OPPORTUNITIES.  The Company has been working closely
with certain customers on the development of "world cars," which are designed by
OEMs in one vehicle center to a single global standard but produced and sold in
different geographic markets. Suppliers for a specific "world car" are often
required to provide their products on a worldwide basis. The Company believes
that it has a competitive advantage in potentially supplying certain world cars
given its international presence, full-service capabilities and existing
position as a leading supplier on the Ford Escort and DEW98 luxury car, as well
as on other existing vehicle platforms which may eventually evolve into world
cars.
 
THE APC ACQUISITION
 
    APC is a leading designer and producer of structural and suspension
components for the automotive, light truck and heavy truck markets. APC's
products include light truck frames, automotive engine cradles, suspension and
other components and heavy truck frame rails. In 1996, over 70% of APC's
revenues was derived from the sale of structural components for light trucks and
sport utility vehicles, a growing segment of the North American automotive
market. APC's customers include the three major North American OEMs as well as
certain Transplants, including Toyota, Nissan, Isuzu and Honda. APC's three
largest customers, Ford, General Motors and Chrysler, accounted for
approximately 46%, 23% and 20%, respectively, of APC's revenues in 1996.
Approximately 11% of APC's revenues in 1996 was derived from the production of
heavy truck frame rails for North American heavy truck OEMs. The Company
believes APC is the largest supplier in this segment, with a market share of
approximately 51% in 1996. APC
 
                                       33
<PAGE>
conducts its operations through 15 facilities which, when added to the Company's
existing 19 facilities, will result in a total of over seven million square feet
of manufacturing floor space.
 
    The Company believes that the APC Acquisition will provide the Company with
several strategic benefits, including the following:
 

    EXPANDED PRODUCT OFFERINGS AND MODULAR PRODUCT OPPORTUNITIES.  The APC
Acquisition will significantly expand the Company's product offerings by adding
lower body structural components to the Company's existing line of upper body
structural components. In addition, APC's products provide an ideal platform for
developing modular product offerings for the Company's customers. APC's frame
and engine cradle products can be combined with a number of the Company's
existing product offerings, including control arms, suspension components,
exhaust hanger assemblies and spring towers and hangers to deliver more complete
systems or modules to its OEM customers at a lower overall cost. The APC
Acquisition will enable the Company to produce a larger portion of a vehicle,
which the Company believes will afford it significant opportunities to increase
revenues as OEMs continue to consolidate their supplier base.

 
    INCREASED CUSTOMER PENETRATION.  The APC Acquisition will significantly
expand the Company's penetration within each of the three major North American
OEMs. Following the APC Acquisition, the Company believes it will be the largest
supplier of structural components to Chrysler, the largest supplier of metal
components to Ford and a major supplier of structural components to General
Motors. The APC Acquisition will also expand the Company's penetration within
certain Transplants by doubling the Company's sales to Toyota, expanding its
already significant position at Honda, increasing sales to Nissan and adding
Isuzu as a new customer.
 

    INCREASED PENETRATION IN LIGHT TRUCK SEGMENT AND OTHER KEY MODELS.  The APC
Acquisition will increase the Company's North American content per vehicle from
$26.74 in 1996 to $77.49 on a pro forma basis and will triple the Company's
content per vehicle in the expanding light truck/sport utility market segment,
which segment represented approximately 60% of the Company's pro forma revenues
for 1996. The APC Acquisition will increase the Company's content per vehicle on
key light truck/sport utility vehicles such as the Ford Explorer and Ranger and
the Chrysler Dakota, Durango and Ram as well as on high volume passenger cars
such as the Ford Taurus/Sable and the Chrysler Intrepid/Concorde/Vision. The
Company believes that this increased model penetration will afford it greater
opportunities to supply additional parts and modules for such models.

 
    COMPLEMENTARY NEW TECHNOLOGY.  The APC Acquisition will provide the Company
with a variety of new and enhanced design and manufacturing process technology,
including APC's patented three piece side rail frame and patented Simulform-TM-
forming technology, the latter of which may result in cost savings and quality
improvements over conventional stamping technology in certain specialized
applications. In addition, APC's existing hydroforming technology complements
the Company's initiatives in this area. The APC Acquisition will also provide
the Company with additional painting, coating and welding technologies and
advanced logistical parts management systems. The Company believes that these
acquired technologies will provide significant additional opportunities to serve
existing customers and obtain new business.
 

    OPERATIONAL EFFICIENCIES.  The APC Acquisition will provide the Company with
a number of opportunities to reduce costs and improve operational efficiency.
For example, APC currently outsources many of its stamping needs, some of which
will be able to be supplied by the Company's existing stamping facilities. In
addition, the Company's and APC's facilities are geographically located in such
a way as to allow the Company to optimize its management and logistical
capabilities on a regional basis. APC's facilities are strategically located
close to many of its and the Company's major customers, allowing for inventory
and freight cost-savings. The increased size of the Company may also improve the
Company's ability to negotiate more favorable terms on its purchasing and supply
contracts, as well as achieve other operational cost savings.

 
                                       34
<PAGE>
    EXPANDED GLOBAL CAPABILITIES.  OEMs are increasingly demanding that their
suppliers have global production capabilities. APC's presence in China, Japan
and South America complements the Company's current European initiatives to
provide expanded global production capabilities for both North American and
international OEMs. See "--Global Initiatives."
 
PRODUCTS
 
    GENERAL.  The Company's current products consist of a broad array of
stamped, formed, welded and assembled metal components, many of which are
critical to the structural integrity of a vehicle. As a result of the APC
Acquisition, the Company will expand its product offerings and will be able to
manufacture and supply its customers with, among other products, light truck
frames, automotive engine cradles, trailing axles and heavy truck frame rails.
These additional products will complement the Company's existing base of
products, many of which are currently attached directly to the frame of a
vehicle at the OEM assembly plant. Following the APC Acquisition, the Company's
products will generally include structural components, suspension components and
engineered assemblies.
 
    STRUCTURAL COMPONENTS.  The Company's current structural component products
form the basic upper body structure of the vehicle and include large metal
stampings such as body pillars, roofrails, side sills, parcel shelves and
intrusion beams. APC's structural component products form the basic lower body
structure of the vehicle and include light truck frames, automotive engine
cradles and heavy truck frame rails. Critical to the strength and safety of
vehicles, structural products carry the load of the vehicle and provide crash
integrity.
 
    SUSPENSION COMPONENTS.  The Company's current suspension component products
include stamped, formed and welded products such as control arms, suspension
links, track bars and spring/shock towers. APC's suspension components include
control arms, suspension links and trailing axles. Critical to the ride,
handling and noise characteristics of a vehicle, suspension components are a
natural extension of the Company's larger structural components.
 
    ENGINEERED ASSEMBLIES.  The Company's current engineered assemblies include
a broad array of highly engineered parts such as hood and deck lid hinges, brake
components and fuel filler assemblies. Such engineered assemblies are a natural
extension to the Company's other products in that they are attached to both
structural and suspension components. The APC Acquisition will not add
materially to the Company's existing array of engineered assembly products.
 
    OTHER.  In addition to the Company's and APC's structural, suspension and
mechanical component products, each of the Company and APC manufactures a
variety of other products, including heat shields and other precision stampings,
for their OEM customers.

    Although a portion of the Company's products are sold directly to OEMs as
finished products, most are used by the Company to produce assemblies consisting
of multiple parts that are welded or otherwise
fastened together by the Company. Systems and assemblies currently produced by
the Company include front and rear structural suspension systems comprised of
control arms, suspension links and axle assemblies consisting of stamped metal
trailing axles, assembled brake shoes, hoses and tie rods. As a result of the
APC Acquisition, the Company will significantly expand its ability to supply
OEMs with systems and modules consisting of integrated assemblies and component
parts that can be installed as a unit in a vehicle at the OEM assembly plant.
 
CUSTOMERS AND MARKETING
 
    The North American automotive market is dominated by General Motors, Ford
and Chrysler, with Transplants representing approximately 20% of this market in
1996. The Company currently supplies its products primarily to Ford, Chrysler,
Honda, General Motors, Toyota, Nissan and Mazda. The APC Acquisition will
significantly expand the Company's penetration within each of the three major
North American OEMs. In addition, the APC Acquisition will also expand the
Company's penetration with certain Transplants, including doubling the Company's
sales to Toyota, expanding its already significant position at Honda, increasing
sales to Nissan and adding Isuzu as a new customer. APC sells its heavy truck
products primarily to Ford, Freightliner Corporation, PACCAR Inc., Volvo/GM
Heavy Truck Corp. and Navistar International Corp.

    OEMs typically award contracts that cover parts to be supplied for a
particular car model. Such contracts range from one year to over the life of the
model, which is generally three to seven years and do not require the purchase
by the customer of any minimum number of parts. The Company and APC also compete
for new business to supply parts for successor models and therefore are subject
to the risk that the OEM will not select the Company to produce parts on a
successor model. The Company and APC supply parts for a broad cross-section of
both new and mature models, thereby reducing their reliance on any particular
model. For example, the Company supplies parts for substantially all models
produced by Ford, Honda and Chrysler and APC currently supplies Chrysler with
substantially all of its full frame requirements.

    Most of the parts the Company and APC produce have a lead time of two to
five years from product development to production. See "--Design and Engineering
Support." Since 1988, the Company has been the leading supplier for hood and
deck hinges at Ford and Chrysler and is responsible for the design and
production of such products. The selling prices of these products are generally
negotiated between the Company and its customers and are typically not subject
to a competitive bid process. APC is currently the largest supplier of
structural components to Chrysler.

    Sales of the Company's and APC's products to OEMs are made directly by their
respective sales and engineering forces, each headquartered in their respective
technical centers located in Farmington Hills, Michigan. Through their technical
centers, the Company and APC service their OEM customers and manage their
continuing programs of product design improvement and development. The Company
and APC each periodically place engineering staff at various customer facilities
to facilitate the development of
 
                                       37
<PAGE>
new programs. After the APC Acquisition, the Company's sales and engineering
force will consist of approximately 460 individuals.
 
DESIGN AND ENGINEERING SUPPORT
 
    The Company strives to maintain a technological advantage through investment
in product development and advanced engineering capabilities. The Company's
manufacturing engineering capabilities enable it to design and build
high-quality and efficient manufacturing systems, processes and equipment and to
continually improve its production processes and equipment. The Company's
manufacturing engineers are located at each of its manufacturing facilities.
 
    As a result of the APC Acquisition, the Company's engineering staff will
increase from approximately 140 to approximately 400 full-time engineers, whose
responsibilities range from research and development, advanced product
development, product design, testing and initial prototype development to the
design and implementation of manufacturing processes.
 
    Because assembled parts must be designed at an early stage in the
development of new vehicles or model revisions, the Company is increasingly
given the opportunity to utilize its product engineering resources early in the
planning process. Advanced development engineering resources create original
engineering designs, computer-aided designs, feasibility studies, working
prototypes and testing programs to meet customer specifications. The Company's
advanced development capabilities have resulted in several innovations in hinge
design that have provided significant benefits to the Company's customers. The
Company also has full service design capability for chassis components. APC has
a long history of developing innovative new designs both to improve the quality
and to lower the cost of its designs. Recent innovations include the patented
three piece side rail, the use of aluminum and other alternative material
applications in its structural components and the use of high-performance
alternative coatings for its structural components, including epoxy coated
primer, two-coat water-reducible coatings, ultrasolids and hybrid coatings.
 
GLOBAL INITIATIVES
 
    The Company has formed, or is in the process of forming, strategic alliances
with other suppliers throughout the world, including in Europe, Asia and Latin
America. The Company has recently opened a European sales and engineering office
to service its U.K. and German OEM customers. In addition, the Company has a
joint manufacturing and marketing agreement with Kirchhoff, a German automobile
parts supplier, pursuant to which the Company and Kirchhoff have agreed to
provide manufacturing and marketing services to each other when and as required
by each company's OEM customers. A current focus of the Company's acquisition
strategy is to acquire European suppliers, which would provide the Company with
a manufacturing presence in Europe and afford the Company access to new customer
opportunities.
 
    The APC Acquisition will significantly expand the Company's global
initiatives. In addition to a Japanese sales office, APC has a 60% ownership
interest in a joint venture located in Changchun, China, which will manufacture
automobile parts for Volkswagen A.G. APC also has a Brazilian subsidiary, which
will be supplying frame components for the Dodge Dakota and has a manufacturing
arrangement to provide cross beams for the Ford Fiesta. Prior to entering into
negotiations with APC, the Company had been investigating the possibility of
opening a sales office in Japan and acquiring an interest in a Brazilian
operation.
 
MANUFACTURING
 
    After the APC Acquisition, the Company's manufacturing operations will
consist primarily of stamping operations, system and modular assembly
operations, roll-forming and hydroforming operations and associated coating and
other ancillary operations. The APC Acquisition will provide the Company with
significant additional stamping and assembly capacity.
 
                                       38
<PAGE>
    Stamping involves passing metal through dies in a stamping press to form the
metal into three-dimensional parts. The Company produces stamped parts using
over 240 precision single-stage, progressive and transfer presses, ranging in
size from 150 to 2,000 tons, which perform multiple functions as raw material
proceeds through the press and is converted into a finished product. The Company
continually invests in its press technology to increase flexibility, improve
safety and minimize die changeover time. The APC Acquisition will broaden the
Company's stamping capabilities by adding over 400 stamping presses ranging from
200 to 4,000 tons in size.
 
    After forming is completed, stampings that are to be used in assemblies are
placed in work-in-progress staging areas from which they are fed into
cell-oriented assembly operations that produce complex, value-added assemblies
through the combination of multiple parts that are welded or fastened together.
The Company's assembly operations are performed on either dedicated, high-volume
welding/fastening machines or on flexible-cell oriented robotic lines for units
with lower volume production runs. The assembly machines attach additional
parts, fixtures or stampings to the original metal stampings. In addition to
standard production capabilities, the Company's assembly machines are also able
to perform various statistical control functions and identify improper welds and
attachments. The Company continually works with manufacturers of fixed/robotic
welding systems to develop faster, more flexible machinery. Several of the
Company's welding systems were designed by the Company.
 
    APC's manufacturing and assembly processes are state-of-the-art. Using
highly-automated assembly processes, APC's new Plymouth, Michigan light truck
frame assembly facility requires no changeover time between the six frame models
it assembles for Chrysler's new Dodge Dakota. Line programmable controllers
adjust assembly equipment to accommodate various frame wheelbase configurations
at various stages of assembly, while robotic welding and material handling
processes are responsible for 99 percent of the facility's frame welding. In
comparison, conventional light truck frame assembly requires equipment and tool
reconfiguration to accommodate various frame models. APC's patented
Simulform-TM- forming process, currently being tested for production use,
simultaneously forms, pierces and joins components of an engine cradle assembly,
resulting in cost savings over traditional stamping techniques, due to a
reduction in the number of presses and operators required and the enhanced
quality and lighter weight of the products manufactured through this method. In
addition, APC's solid state welding capabilities allow it to weld at lower
temperatures which results in less structural distortion of products,
exceptional weld quality and higher production rates than conventional welding
processes. APC also utilizes a significant number of robots in its frame
riveting processes and automated transfer systems in addition to their use in
welding operations.
 
    The products manufactured by the Company and APC use various grades and
thicknesses of steel and aluminum, including hot and cold rolled, galvanized,
organically coated, stainless and aluminized steel. Neither the Company nor APC
produces exposed sheet metal components, such as exterior body panels. See
"--Suppliers and Raw Materials."
 
    OEMs have established quality rating systems involving rigorous inspections
of suppliers' facilities and operations. OEMs' factory rating programs provide a
quantitative measure of a company's success in improving the quality of its
operations. The Company and APC have each received quality awards from Ford (Q1)
and Chrysler (Pentastar) and the Company has consistently received one of Ford's
highest commercial ratings for suppliers in the stamping segment. The automotive
industry has recently adopted a quality rating system known as QS-9000. The
Company has recently received QS-9000 certification and APC expects to receive
such certification by the end of 1997.
 
COMPETITION
 
    The Company operates in a highly competitive, fragmented market segment of
the automotive supply industry, with a limited number of competitors generating
revenues in excess of $200 million. The number of the Company's competitors has
decreased in recent years and is expected to continue to decrease due to the
supplier consolidation resulting from changing OEM policies. The Company's
largest competitors include The Budd Company, a subsidiary of Thyssen AG
("Budd"), Magna International Inc. ("Magna"),

OEMs with internal stamping and assembly operations, all of which have
substantial financial resources. The Company competes with Magna across most of
the Company's product lines, and with its other significant competitors in
various segments of its product lines. For example, the Company competes with
Budd for large stampings, while it competes with ITT Automotive for hinge
business. Aetna Industries, Active Tool & Die Co., AG Simpson, Lobdell-Emory
Mfg. Co. and L&W Engineering compete with the Company for medium-size structural
stampings.
 
    APC also operates in a highly competitive market segment that is
significantly less fragmented than the Company's market segment. APC's principal
competitors include Dana Corporation, Magna and internal divisions of OEMs, all
of which are large and have substantial resources. APC also competes with
Midland Corporation across its heavy truck product lines.
 
    The Company and APC principally compete for new business both at the
beginning of the development of new models and upon the redesign of existing
models. New model development generally begins two to five years before the
marketing of such models to the public. Once a producer has been designated to
supply parts for a new program, an OEM usually will continue to purchase those
parts from the designated producer for the life of the program, although not
necessarily for a redesign. Competitive factors in the market for the Company's
and APC's products include product quality and reliability, cost and timely
delivery, technical expertise and development capability, new product innovation
and customer service.
 
SUPPLIERS AND RAW MATERIALS
 
    The primary raw material used to produce the majority of the Company's
products is steel. The Company purchases hot and cold rolled, galvanized,
organically coated, stainless and aluminized steel from a variety of suppliers.
The Company employs just-in-time manufacturing and sourcing systems enabling it
to meet customer requirements for faster deliveries while minimizing its need to
carry significant inventory levels. The Company has not experienced any
significant shortages of raw materials and normally does not carry inventories
of raw materials or finished products in excess of those reasonably required to
meet production and shipping schedules. Raw materials costs represented
approximately 53% of the Company's revenues in 1996, and steel represented
approximately 70% to 75% of raw material costs in 1996.
 
    Honda and Chrysler currently purchase all of the steel used by the Company
for their models directly from steel producers. Ford is in the process of
implementing a similar program. As a result, the Company will have minimal
exposure to changes in steel prices for parts supplied to Ford, Honda and
Chrysler, which collectively represented 86% of the Company's revenues in 1996.
APC currently purchases substantially all of the steel used in its manufacturing
operations from steel manufacturers, either directly or through distributors.
The Company expects that APC will adopt a similar arrangement with such
customers following the APC Acquisition.
 
    The Company expects that the content level of metal in cars and light trucks
will remain constant or increase slightly due to the trend toward increased
vehicle size and a greater emphasis on metal recycling. Although the search for
improved fuel economy and weight reduction has resulted in attempts to reduce
the sheet metal content of light vehicles, an efficient, cost-effective
substitute for steel used in the Company's structural products has not been
found. While various polymers have been used recently for fenders, hoods and
decks, such products do not have the inherent strength or structural integrity
on a cost-effective basis to be used for structural components. The Company and
APC are involved in ongoing evaluations of the potential for the use of aluminum
and of specialty steel in their products.
 
    Other raw materials purchased by the Company include dies, fasteners,
tubing, springs, rivets and rubber products, all of which are available from
numerous sources. APC currently outsources many of its stamping needs, some of
which can be supplied by the Company's existing stamping facilities.

FACILITIES
 
    The Company maintains several manufacturing facilities located in close
proximity to many of the high-volume vehicle assembly plants in the United
States. In addition, APC has located its facilities close to its major OEM
customers in order to facilitate the just-in-time delivery requirements of its
customers and to minimize freight delivery costs. The Company's and APC's
facilities are geographically located in such a way as to enable the Company to
optimize their management and logistical capabilities on a regional basis.
 
    The following table provides information regarding the Company's and APC's
principal facilities:

(1) Facility is subject to an IRB financing arrangement pursuant to which the
    Company or APC makes periodic lease payments and has the option to acquire
    such facility for nominal consideration at the end of the term.
 
(2) Facility is leased by a joint venture in which APC holds a 60% equity
    interest.
 
    Management believes that substantially all of the Company's and APC's
property and equipment is in good condition. In order to increase efficiency,
the Company expects to make capital expenditures for equipment upgrades at the
facilities recently acquired in the MSTI Acquisition. See "Management's
Discussion and Analysis of Results of Operations and Financial
Condition--Liquidity and Capital Resources."
 
    The Company believes that its existing facilities will be adequate to meet
its production demands for the foreseeable future. The Company's facilities were
specifically designed for the manufacturing of the
 
                                       41
<PAGE>
Company's products. The utilization and capacity of such facilities are
dependent upon the mix of products being produced by the Company.
 
EMPLOYEES
 

    The Company currently has approximately 2,900 employees, of whom
approximately 1,100 are covered under collective bargaining agreements, one of
which expires in July 1997. The Company currently anticipates that it will enter
into a new collective bargaining agreement prior to the expiration of such
agreement. The remaining collective bargaining agreements expire in 1999. The
Company believes that its future success will depend in part on its ability to
continue to recruit, retain and motivate qualified personnel at all levels of
the Company. The Company has instituted a large number of employee programs to
increase employee morale and expand the employees' participation in the
Company's business. The Company has not experienced any work stoppages and
considers its relations with its employees to be good.

 
    APC currently has approximately 5,300 employees, of whom approximately 2,900
are covered under several collective bargaining agreements, the earliest of
which expires in September 1998. The Company believes APC's relations with its
employees are generally good. The Company expects to retain APC's employees on
substantially the same terms and conditions of employment as were in place prior
to the APC Acquisition.
 
ENVIRONMENTAL MATTERS
 
    The Company believes it conducts its operations in substantial compliance
with applicable environmental and occupational health and safety laws. The
Company does not expect to incur material capital expenditures for environmental
compliance during its current or succeeding fiscal year. However, as is the case
with manufacturers in general, if a release of hazardous substances occurs on or
from the Company's properties or at any associated offsite disposal location, if
contamination from prior activities is discovered at any of the Company's
properties or if non-compliance with environmental regulations or permits is
discovered, the Company may be held liable and the amount of such liability
could be material. In connection with the Trylon and MSTI Acquisitions,
MascoTech has agreed to indemnify the Company for certain environmental matters,
including replacement of underground storage tanks at the Traverse City
facilities and any remediation that may be required at the Kendallville
facility.
 
    In connection with the APC Acquisition, A.O. Smith has agreed, subject to
certain limitations, to indemnify the Company for environmental matters relating
to APC arising from events occurring, or conditions arising, prior to the date
of the APC Acquisition. This indemnification obligation applies to claims to the
extent exceeding $250,000 submitted by the Company within three years of the
acquisition date. To the extent that such claims exceed $5.0 million in the
aggregate, A.O. Smith will indemnify 70% of such losses, up to A.O. Smith's
maximum $75.0 million indemnification obligation under the purchase agreement.
In addition, A.O. Smith has agreed to retain certain environmental liabilities
for, among other things, liabilities arising from offsite disposal of hazardous
substances prior to the APC Acquisition.
 
LEGAL PROCEEDINGS
 

    The Company is not currently involved in any material lawsuits. The Company
believes it maintains adequate insurance, including product liability coverage.
The Company historically has not been required to pay any material liability
claims. APC is subject to a number of outstanding lawsuits arising in the
ordinary course of its business. A.O. Smith has agreed, however, to retain
responsibility for all material lawsuits relating to APC and to indemnify the
Company for any losses it may incur in connection with such lawsuits.

 

    A.O. Smith is a party to a lawsuit alleging, among other things, that APC
misappropriated trade secrets from one of its competitors in developing certain
techniques used in a hydroforming process being developed by APC. In connection
with the APC Acquisition, A.O. Smith has retained the liability relating to this
litigation and has agreed to indemnify the Company for any monetary damages it
may incur as a result of such litigation. A.O. Smith has informed the Company
that it believes this suit to be without merit and is asserting various defenses
to such allegations. The hydroforming process currently being used by APC is not
the subject of this lawsuit. As a result, the Company does not currently believe
that its ability to utilize APC's hydroforming technology will be materially
impaired even if A.O. Smith is found liable in such suit.

- ------------------------
 

(1) Prior to the Offering, Onex had shared voting power of 3,064,120 shares and
    sole dispositive power of 1,486,778 shares. OMI has informed the Company of
    its intention to purchase an aggregate of 500,000 shares in the Offering in
    order for Onex to realign its ownership interest in the Company. As a
    result, the Company has requested that the Underwriters reserve up to
    500,000 shares for sale to OMI at the public offering price. Upon completion
    of the Offering, Onex is expected to have beneficial ownership of 500,000
    shares. See "Underwriting."

 
(2) The partners of J2R are S. A. Johnson, Scott D. Rued, W. H. Clement, Robert
    R. Hibbs, Mary L. Johnson and Carl E. Nelson.
 
    Set forth below are the material relationships which existed between the
Company and the Selling Stockholders during the last three years:
 

    The Company, Onex and certain stockholders, including J2R and its partners,
are parties to a registration agreement pursuant to which the Company has
granted such stockholders rights to register their shares of Common Stock.
Pursuant to the terms of such agreement, the Company will pay all expenses of
the Offering attributable to the Selling Stockholders other than underwriting
discounts and commissions that may be incurred by them.

 

    The Company, Onex, J2R and its partners and certain other investors, who
collectively own 2,310,836 shares of Common Stock (prior to the Offering), are
parties to an Investor Stockholders Agreement pursuant to which each party has
agreed to vote his or its shares in the same manner that Onex votes its shares
of Common Stock. In addition, certain members of management, who collectively
own 753,284 shares of Common Stock, have executed irrevocable proxies that grant
Onex the right to vote such shares on all matters presented to the Company's
stockholders for a vote. These voting arrangements will terminate upon
completion of the Offering.

 

    In 1994, Hidden Creek, a partnership affiliated with Onex and J2R, received
$333,000 for providing strategic direction, management and financial services to
the Company. In addition, in 1994 the Company paid Hidden Creek an aggregate of
$500,000 for services rendered in connection with the acquisitions of Edgewood
and Kalamazoo. In 1996, the Company paid Hidden Creek an aggregate of $750,000
for services in connection with the acquisitions of Trylon and MSTI. The Company
expects to pay Hidden Creek an aggregate of $1,250,000 for services rendered in
connection with the APC Acquisition.

 
    In May 1994, Onex acquired 788,831 shares of Common Stock for aggregate
consideration of $2,543,599 and J2R acquired 197,207 shares of Common Stock for
aggregate consideration of $4,176. Onex and J2R are parties to a Co-Investment
Agreement pursuant to which they have agreed to an allocation of the purchase
price of their investments. As a result of this allocation, the combined price
per share paid by Onex and J2R in connection with the purchase of the
above-described shares is the same price per share paid by all other
stockholders acquiring shares at such time.

                      DESCRIPTION OF NEW CREDIT AGREEMENT
 

    In connection with the APC Acquisition, the Company's principal operating
subsidiary expects to enter into the New Credit Agreement. Proceeds from
borrowings under the New Credit Agreement will be used to (i) pay a portion of
the cash purchase price of the APC Acquisition; (ii) redeem the Senior Notes;
and (iii) pay transaction fees and expenses associated with the APC Acquisition.
In the event that this Offering has not been completed at the time of the
consummation of the APC Acquisition, the Company will finance the entire APC
Acquisition with the proceeds from borrowings under the New Credit Agreement.
The Company anticipates that the New Credit Agreement will provide for a six
year revolving credit facility of up to $750 million, with a letter of credit
sublimit of $100 million and an alternative currency facility sublimit of $55
million. In addition, an additional loan of up to $200 million will be made
available to the Company in the event the APC Acquisition is consummated prior
to the receipt of the proceeds of the Offering. This loan would have a term of
18 months and would be fully repaid from the proceeds of the Offering. The
following description of the material terms of the New Credit Agreement is
qualified in its entirety by reference to the executed letter agreement relating
to the New Credit Agreement, which has been filed as an exhibit to the
Registration Statement of which this Prospectus is a part.

 

    Indebtedness under the New Credit Agreement will be guaranteed by the
Company and certain of its subsidiaries (with exceptions for foreign
subsidiaries to be mutually agreed upon).

 

    The loans under the New Credit Agreement will bear interest at a rate per
annum equal to, at the Company's option, (i) the Base Rate or (ii) the reserve
adjusted LIBOR Rate plus a margin ranging from 17 to 50 basis points, depending
upon the ratio of the consolidated indebtedness of the Company to stockholders'
investment. Adjustments to the margin set forth above will be made according to
the pricing matrix that will be attached to the New Credit Agreement.

 

    The New Credit Agreement will require the Company to meet certain financial
tests, including but not limited to minimum interest coverage, minimum
debt/capital and maximum leverage ratio. The New Credit Agreement will also
contain covenants which, among other things, will limit (i) the incurrence of
additional indebtedness and contingent obligations; (ii) the creation of liens
and encumbrances; (iii) the payment of dividends; (iv) additional investments;
(v) prepayments of other indebtedness; (vi) asset sales, acquisitions, joint
ventures, mergers and consolidations; (vii) transactions with affiliates; and
(viii) other matters customarily restricted in such agreements.

 
    The New Credit Agreement will contain customary events of default including
but not limited to (i) payment defaults; (ii) breach of representations and
warranties; (iii) noncompliance with covenants; (iv) bankruptcy; (v) judgments
in excess of specified amounts; (vi) failure of any guaranty or security
agreement supporting the New Credit Agreement to be in full force and effect;
(vii) defaults under other instruments or agreements of indebtedness; and (viii)
a Change of Control (as such term will be defined in the New Credit Agreement).

    The Underwriting Agreement provides that the obligations of the several
Underwriters to pay for and accept delivery of the shares of the Common Stock
offered hereby are subject to approval of certain legal matters by counsel and
to certain other conditions. The Underwriters are obligated to take and pay for
all the shares of the Common Stock if any are taken.
 

    The Company has been advised that the Underwriters propose to offer the
shares of the Common Stock in part directly to the public initially at the
public offering price set forth on the cover page of this Prospectus and in part
to certain dealers at such price less a concession not in excess of $.  per
share; that the Underwriters may allow, and such dealers may reallow, a
concession not in excess of $.  per share on sales to other dealers; and that
after the public offering, the public offering price and other selling terms may
be changed by the Underwriters. The Underwriters have informed the Company that
they do not intend to confirm sales to any accounts over which they exercise
discretionary authority.

 
    The Company has granted to the Underwriters an option, exercisable for 30
days from the date of this Prospectus, to purchase up to an aggregate of
1,513,500 additional shares of Common Stock at the price to the public less
underwriting discounts and commissions. The Underwriters may exercise such
option only for the purpose of covering over-allotments, if any, incurred in
connection with the sales of Common Stock offered hereby. To the extent that the
Underwriters exercise such option, each Underwriter will become obligated,
subject to certain conditions, to purchase the same percentage of such
additional shares as the number of other shares to be purchased by that
Underwriter bears to the total number of shares set forth on the cover page of
this Prospectus.
 
    The Company, its Directors and executive officers, the Selling Stockholders
and certain other stockholders have agreed with the Underwriters not to offer,
sell, contract to sell, grant any other option to purchase or otherwise dispose
of any shares of the Common Stock or any securities convertible into or
exercisable for, or warrants, rights or options to acquire, shares of Common
Stock for a period of 90 days without the prior written consent of DLJ, other
than sales of Common Stock under the Underwriting Agreement, the issuance of
shares of Common Stock upon the exercise of outstanding options and certain
transfers to affiliates.
 

    At the request of the Company, the Underwriters have reserved up to 500,000
shares of Common Stock for sale at the public offering price to OMI. The number
of shares of Common Stock available to the general public will be reduced to the
extent OMI purchases any of the reserved shares. Any reserved shares of Common
Stock that are not so purchased by OMI at the closing of the Offering will be
offered by the Underwriters to the general public on the same terms as the other
shares in the Offering.

<PAGE>
    The Company, its principal operating subsidiaries and the Selling
Stockholders have agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that they may be required to make in respect thereof.
 

    In connection with the Offering, the Underwriters may engage in transactions
that stabilize, maintain or otherwise affect the price of the Common Stock.
Specifically, the Underwriters may overallot the Offering, creating a syndicate
short position. Underwriters may bid for and purchase shares of Common Stock in
the open market to cover syndicate short positions. In addition, the
Underwriters may bid for and purchase shares of Common Stock in the open market
to stabilize the price of the Common Stock. These activities may stabilize or
maintain the market price of the Common Stock above independent market levels.
The Underwriters are not required to engage in these activities, and may end
these activities at any time.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Tower Automotive, Inc.:
 
    We have audited the accompanying consolidated balance sheets of Tower
Automotive, Inc. (a Delaware corporation) and Subsidiaries as of December 31,
1995 and 1996, and the related consolidated statements of operations,
stockholders' investment and cash flows for each of the three years in the
period ended December 31, 1996. These consolidated financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these consolidated financial statements based on our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Tower
Automotive, Inc. and Subsidiaries as of December 31, 1995 and 1996, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1996 in conformity with generally accepted
accounting principles.

</TABLE>
 
    CUSTOMER TOOLING AND OTHER DESIGN COSTS:
 
    Customer tooling represents costs incurred by the Company in the development
of new tooling used in the manufacture of the Company's products. Once customer
approval is obtained for the manufacture of a new product, the Company is
reimbursed by its customers for the cost of certain of the tooling, at which
time the tooling becomes the property of the customers.
 
    In addition, the Company has certain other tooling and design costs related
to previously proven product designs which are reimbursed by the Company's
customers as the related product is sold through an incremental increase in each
product's unit selling price. Such costs are capitalized and amortized using the
unit of production method over the life of the related tool. Amounts capitalized
and included in other assets were $3.8 million at December 31, 1995 and $3.7
million at December 31, 1996. If the Company forecasts that the amount of
capitalized tooling and design costs exceeds the amount to be realized through
the sale of product, a loss is recognized currently.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment acquired in the acquisitions discussed in Note
3 was recorded at its fair value, determined based on appraisals, as of the
respective acquisition dates. Additions to property, plant and equipment
following the acquisitions are stated at cost. For financial reporting purposes,
depreciation and amortization are provided using the straight-line method over
the following estimated useful lives:
 
<TABLE>
<S>                                                            <C>
                                                                 15 to 30
Buildings and improvements...................................      years
Machinery and equipment......................................  3 to 20 years
</TABLE>
 
    Accelerated depreciation methods are used for tax reporting purposes.
 
    Start-up costs related to major facilities and new platforms are capitalized
and amortized over the life of the related platform, generally five years. The
unamortized start-up cost balance was $876,000 at December 31, 1995 and
$1,011,000 at December 31, 1996.
 
    Interest is capitalized during the construction of major facilities and is
amortized over the related estimated useful lives. Interest costs of $1,157,000
were capitalized during the year ended December 31, 1995. No interest was
capitalized during the year ended December 31, 1996.
 
    Maintenance and repairs are charged to expense as incurred. Major
betterments and improvements which extend the useful life of the related item
are capitalized and depreciated. The cost and accumulated depreciation of
property, plant and equipment retired or otherwise disposed of are removed from
the related accounts, and any residual values are charged or credited to income.
 
    OTHER ASSETS:
 
    Goodwill represents the excess of the purchase price over the fair value of
the net assets acquired and is being amortized on a straight-line basis over 40
years. Debt issue costs are amortized on a straight-line basis over the term of
the related obligations.
 
    The Company periodically evaluates whether events and circumstances have
occurred which may affect the estimated useful life or the recoverability of the
remaining balance of its goodwill and other long-lived assets. If such events or
circumstances were to indicate that the carrying amount of these assets were not
recoverable, the Company would estimate the future cash flows expected to result
from the use of the assets and their eventual disposition. If the sum of the
expected future cash flows (undiscounted and without interest charges) were less
than the carrying amount of goodwill, the Company would recognize an impairment
loss.
 

    FAIR VALUE OF FINANCIAL INSTRUMENTS:

 

    The carrying amounts of the Company's borrowings under the outstanding
industrial development revenue bonds approximates fair value as the floating
rates applicable to these financial instruments reflect changes in the overall
market interest rates. The carrying amount of the Company's outstanding series A
and series B senior notes also approximate fair value as interest rates have not
changed materially since their issuance in May 1996.

2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)

    REVENUE RECOGNITION:

 

    The Company recognizes revenue as its products are shipped to its customers.

 
    INCOME TAXES:
 
    The Company accounts for income taxes under the liability method, whereby
deferred income taxes are recognized at currently enacted income tax rates to
reflect the tax effect of temporary differences between the financial reporting
and tax bases of assets and liabilities.
 
    NET INCOME PER COMMON AND COMMON EQUIVALENT SHARE:
 
    Net income per common and common equivalent share is computed by dividing
net income applicable to common stockholders by the weighted average number of
common and common stock equivalent shares outstanding during each period
presented. Common stock issued and common stock options granted within one year
immediately preceding the initial public offering of common stock (Common Stock)
discussed in Note 4 at prices below the public offering price have been
reflected in the net income per share calculation as if they had been
outstanding for all periods presented. Net income for purposes of computing net
income per common and common equivalent share reflects the elimination of
interest expense on the convertible subordinated notes, net of the related
income tax benefit.
 

    STOCK OPTIONS:

 

    The Company accounts for stock options under the provisions of APB No. 25,
under which no compensation expense is recognized when the stock options are
granted. The pro forma effects had the Company followed the provisions of SFAS
No. 123 are included in Note 4.

 
    USE OF ESTIMATES:
 
    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 and
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. The ultimate results could differ from those estimates.
 
3. ACQUISITIONS:
 
    On May 4, 1994, the Company acquired the operating assets and assumed
certain operating liabilities and indebtedness of Edgewood Tool and
Manufacturing Company (Edgewood), a manufacturer of hood and deck lid hinges and
structural metal components for the automotive industry, for total consideration
of $24.6 million in cash and assumed indebtedness and the issuance of $5.0
million of Convertible Subordinated Notes. In addition, the Company entered into
a five year employment agreement with Edgewood's former president and issued an
option to acquire 102,984 shares of Common Stock at an exercise price of $6.55
per share.
 
    On June 29, 1994, the Company acquired the capital stock of Kalamazoo
Stamping and Die Company (Kalamazoo), a supplier of structural metal stampings
and assemblies for the automotive industry, for net consideration of
approximately $12.3 million in cash.

3. ACQUISITIONS: (CONTINUED)
    On January 16, 1996, the Company acquired all of the outstanding common
stock of Trylon Corporation (Trylon) for total consideration of approximately
$25 million. The acquisition was financed with the proceeds of a $25 million
term loan. Trylon manufactures metal stampings and assemblies for the North
American automotive industry from four facilities in Traverse City, Michigan.
 

    On May 31, 1996, the Company acquired all of the outstanding common stock of
MascoTech Stamping Technologies, Inc. (MSTI), a wholly owned subsidiary of
MascoTech, Inc. (MascoTech). Consideration consisted of $55 million in cash,
785,000 shares of the Company's Common Stock and warrants to acquire 200,000
shares of the Company's Common Stock at an exercise price of $18 per share. The
Company may also make additional payments of up to $30 million to MascoTech if
certain operating targets are achieved by the MSTI facilities in the first three
years following the acquisition. The amounts to be paid to MascoTech are equal
to two times the amount by which operating profit, as defined, of the MSTI
facilities exceeds $24 million each year. Based on results of operations of the
MSTI facilities through December 31, 1996, no contingent payments are due.
Contingent consideration paid in future periods, if any, will be recorded as
additional goodwill. MSTI manufactures metal chassis and suspension components
and assemblies for the North American automotive industry from facilities in
Ohio, Indiana and Michigan.

 

    These acquisitions have been accounted for using the purchase method of
accounting and, accordingly, the assets acquired and liabilities assumed have
been recorded at fair value as of the dates of the acquisitions. The assets and
liabilities of Trylon and MSTI have been recorded based upon preliminary
estimates of fair value as of the dates of acquisition. The Company does not
believe the final allocations of the purchase price will be materially different
than the preliminary allocations. The excess of the purchase price over the fair
value of the assets acquired and liabilities assumed has been recorded as
goodwill. Results of operations for these acquisitions have been included in the
accompanying consolidated financial statements since the dates of acquisition.
The accompanying unaudited consolidated pro forma results of operations for the
years ended December 31, 1995 and 1996 give effect to the 1996 Offering (as

4. STOCKHOLDERS' INVESTMENT:
 
    PUBLIC OFFERINGS OF COMMON STOCK:
 
    In August 1994, the Company completed an initial public offering, including
shares issued pursuant to the underwriters' over-allotment option, of 4,887,500
shares of its Common Stock at $11.50 per share resulting in net proceeds to the
Company of approximately $51.3 million.
 
    During 1996, the Company completed an offering of 2,232,900 shares of its
Common Stock at an offering price of $24.50 per share (the 1996 Offering)
resulting in net proceeds of approximately $51.3 million. Proceeds from the 1996
Offering were used by the Company to retire borrowings under its secured credit
agreement and for general corporate purposes.
 
    PRIVATE PLACEMENTS:
 
    During 1993, the Company sold 522,640 shares of its Common Stock to certain
employees for aggregate proceeds of approximately $981,000. Approximately
$434,000 of this amount was financed through notes to the Company which bear
interest at prime plus 1% (9.5% at December 31, 1995 and 9.25% at December 31,
1996) and are due in 1998. These notes are reflected as a reduction of
stockholders' investment in the accompanying consolidated financial statements.
Approximately $248,000 and $330,000 of these notes had been collected as of
December 31, 1995 and 1996.
 
    As a component of the financing for the acquisition of Edgewood in May 1994
(See Note 3), the existing stockholders and members of the Company's management
participated in a $4.1 million private placement of 1,585,365 shares of Common
Stock, resulting in net cash proceeds to the Company of $3.7 million.
Approximately $404,000 of this amount was financed through notes to the Company
which bear interest at prime plus 1% and are due in 1999. These notes are
reflected as a reduction of stockholders' investment in the accompanying
consolidated financial statements. Approximately $93,000 and $333,000 of these
notes had been collected as of December 31, 1995 and 1996.
 
    STOCK OPTION PLAN:
 
    The Company sponsors the 1994 Key Employee Stock Option Plan (the Stock
Option Plan), under which any person who is a full-time, salaried employee of
the Company (excluding non-management directors) is eligible to participate in
the Stock Option Plan (an Employee Participant). A committee of the board of
directors selects the Employee Participants and determines the terms and
conditions of the options. The Stock Option Plan provides for the issuance of
options up to 500,000 shares of Common Stock at exercise prices equal to the
stock market price on the date of grant to Employee Participants,

    As of December 31, 1996, the outstanding stock options granted in 1995 have
a remaining contractual life of approximately 8.5 years and the outstanding
stock options granted in 1996 have a remaining contractual life of approximately
9.5 years.

 
    INDEPENDENT DIRECTOR STOCK OPTION PLAN:
 
    In February 1996, the Company's board of directors approved the Tower
Automotive, Inc. Independent Director Stock Option Plan (the Director Option
Plan) that provides for the issuance of options to Independent Directors, as
defined, to acquire up to 100,000 shares of the Company's Common Stock, subject
to certain adjustments reflecting changes in the Company's capitalization. The
option exercise price must be at least equal to the fair value of the Common
Stock at the time the option is issued. Vesting is determined by the Board of
Directors at the date of grant and in no event can be less than six months from
the date of grant. As of December 31, 1996, the Company had granted stock
options under this plan to acquire 22,500 shares of Common Stock at an exercise
price of $15.125 per share. None of these director options were exercisable or
vested at December 31, 1996.
 
    EMPLOYEE STOCK PURCHASE PLAN:
 
    The Company also sponsors an employee stock discount purchase plan which
provides for the sale of up to 500,000 shares of the Company's Common Stock at
discounted purchase prices, subject to certain limitations. The cost per share
under this plan is 85% of the market value of the Company's Common Stock at the
date of purchase, as defined. During the year ended December 31, 1995, 4,143
shares of Common Stock were issued to employees pursuant to this plan and during
the year ended December 31, 1996, 18,350 shares of Common Stock were issued. The
weighted average fair value of shares sold in 1995 and 1996 were $8.11 and
$14.32, respectively.
 
    STOCK-BASED COMPENSATION PLANS:
 
    As discussed above, the Company has two stock option plans, the Stock Option
Plan and the Independent Director Stock Option Plan, and an Employee Stock
Purchase Plan. The Company accounts

for these plans under APB Opinion No. 25, under which no compensation cost has
been recognized. Had compensation cost for these plans been determined
consistent with Statement of Financial Accounting Standards No. 123, "Accounting
for Stock-Based Compensation," (SFAS No. 123), the Company's pro forma net
income and pro forma earnings per share would have been as follows (in
thousands):

    Because the SFAS No. 123 method of accounting has not been applied to
options granted prior to January 1, 1995, the resulting pro forma compensation
cost may not be representative of that to be expected in future years. The
effect of the stock offered under the Employee Stock Purchase Plan was not
material for 1995 and 1996.
 
    The fair value of each option grant is estimated on the date of the grant
using the Black-Scholes option pricing model with the following weighted average
assumptions: risk free interest rates of 6.5%, 6.9% and 6.93% in 1995 and 5.57%
in 1996; expected life of seven years for 1995 and 1996; expected volatility of
35%, 37% and 41% in 1995 and 56% in 1996.
 
    OTHER COMMON STOCK EQUIVALENTS:
 
    In connection with the acquisition of Edgewood in May 1994, the Company
issued an option to acquire 102,984 shares of Common Stock at an exercise price
of $6.55 per share. The options expire in 2004. As of December 31, 1996, 34,328
options were vested and exercisable.
 
    In connection with the acquisition of MSTI in May 1996, the Company issued
warrants to MascoTech to acquire 200,000 shares of Common Stock at an exercise
price of $18 per share. The warrants expire in 2006.
 

    DIVIDENDS:

 

    The Company has not declared or paid any cash dividends in the past, as
discussed in Note 5, the Company's debt agreements restrict the amount of
dividends the Company can declare or pay. As of December 31, 1996, under the
most restrictive debt covenants, the Company could not have paid any cash
dividends.

December 31, 1996. The weighted average interest rate for borrowings under the
revolving credit facility was 7.4% for the year ended December 31, 1995 and 6.1%
for the year ended December 31, 1996. In connection with the transaction
described in Note 10, the Company obtained a commitment from a bank to refinance
the existing Credit Agreement.
 
    The Company financed the cash portion of the MSTI acquisition through the
issuance in two series of Senior Notes having an aggregate principal amount of
$65 million. The Senior Notes require the Company to make semi-annual interest
payments commencing December 1, 1996, while principal is payable in varying
annual installments beginning in 2000. Net proceeds from the sale of the Senior
Notes in excess of the amounts used to finance the cash portion of the MSTI
acquisition, together with borrowings under the revolving credit facility, were
used to repay in full the remaining balance outstanding on a $25 million term
loan incurred by the Company in connection with the acquisition of Trylon.
 
    In connection with the acquisition of Edgewood in May 1994, the Company
issued the $5.0 million Convertible Subordinated Notes, which generally are
convertible at any time into 823,874 shares of Common Stock. The Convertible
Subordinated Notes are subject to prepayment in the event of, and become
convertible upon, a sale of the Company and are subordinated to all other debt
of the Company which is not expressly subordinated to the Convertible
Subordinated Notes. As of December 31, 1996, approximately $2.5 million of these
notes had been converted into 410,529 shares of Common Stock.
 
    In June 1994 and March 1995, the Company issued $25.0 million and $20.0
million, respectively, of industrial development revenue bonds related to the
construction and equipping of a manufacturing facility in Bardstown, Kentucky.
The bonds are collateralized by letters of credit. The facility will be
completed in two phases. The undispersed proceeds from these bonds are invested
in treasury securities and reflected as restricted cash in the accompanying
consolidated balance sheets. The Company also has approximately $2.9 million in
outstanding indebtedness relating to industrial development revenue bonds issued
in connection with the construction of its Auburn, Indiana plant. The bonds are
collateralized by a letter of credit, certain equipment and a mortgage on this
plant.
 
    The debt agreements described above contain various restrictive covenants
which, among other matters, require the Company to maintain certain financial
ratios. The agreements also limit additional indebtedness, capital expenditures
and cash dividends. The Company was in compliance with all debt covenants as of
December 31, 1995 and 1996.

    As of December 31, 1995, the Company had provided a valuation allowance for
certain deferred tax assets as their realization was not reasonably assured.
During 1996, the Company determined it was more likely than not that the
deferred tax assets would be realized. Accordingly, the valuation allowance was
eliminated as a reduction to goodwill.

    The discount rate used in determining the actual present value of the
projected benefit obligation was 7% in 1995 and 7.5% 1996. The expected
long-term rate of return on plan assets was 8% for December 31, 1995 and 1996.
Plan assets consist principally of mutual funds invested in bonds and equity
securities.
 
    DEFERRED COMPENSATION PLAN:
 
    The Company had salary continuation agreements with three employees which
provided for certain payments beginning with the later of retirement or
attainment of age 62, or in the event of death or disability. During 1995 two of
these employees received payments totaling $529,000 as a result of their
retirement. The expense under this plan has not historically been significant.
The Company's total obligation under these agreements was $318,000 as of
December 31, 1995 and $334,000 as of December 31, 1996 and was included in
noncurrent liabilities in the accompanying consolidated balance sheets.
 
    POSTRETIREMENT PLANS:
 
    The Company provides certain medical insurance benefits for retired
employees. Certain employees of the Company are eligible for these benefits if
they remain employed until age 55 or 59 and fulfill other eligibility
requirements specified by the plans. Certain retirees between the ages of 55 and
62 must contribute 100% of the group rate for active employees. No contributions
are required for retirees 62 or older. Benefits are continued for dependents of
eligible retiree participants after the death of the retiree.

    The projected postretirement benefit obligation is calculated using a 7.5%
annual rate of increase in per capita claims cost in 1995 and 7.0% in 1996. This
rate is assumed to decrease by one half of one percent per year through 1997. In
1998, the rate is assumed to be 6.5% and remain at that level for all years
thereafter.
 
    If the health care cost trend rate were increased one percentage point, the
accumulated postretirement benefit obligation and the aggregate of the service
and interest cost discussed above would have increased by 12%.

9. RELATED PARTY TRANSACTIONS: (CONTINUED)
    The Company has made payments to Hidden Creek Industries, an affiliate of
the Company, for certain acquisition related and other management services
totaling $833,000 during 1994 and $750,000 during 1996.
 
10. AGREEMENT TO ACQUIRE AUTOMOTIVE PRODUCTS COMPANY:
 
    On January 27, 1997, the Company entered into an agreement to acquire and
assume substantially all of the assets and liabilities of the Automotive
Products Company (APC), a division of A.O. Smith Corporation, for $625 million
in cash, subject to certain adjustments. APC, which had revenues of
approximately $860 million for the year ended December 31, 1996, designs and
manufactures frames, frame components, engine cradles, suspension components and
modules for the North American automotive and heavy truck industries. This
acquisition is expected to close during the second quarter of 1997. This
acquisition will be accounted for as a purchase and, accordingly, APC's assets
and liabilities will be recorded at fair value as of the acquisition date, with
any excess purchase price recorded as goodwill.
 

    In connection with this acquisition, the Company agreed to enter into a new
credit facility with a bank, which will provide a total financing availability
of up to $865 million. The specific terms of the new credit facility are
currently being negotiated with the bank. The new credit facility will also
include certain restrictive covenants, which the Company expects will be similar
in nature to those in its existing credit agreement. This facility will become
effective contemporaneously with the completion of the acquisition discussed
above.

 
    As part of this refinancing, the Company expects a portion of the proceeds
from the new credit facility will be used to retire the Senior Notes discussed
in Note 5. If the Senior Notes are retired, the Company will record an
extraordinary loss of approximately $3 million, net of income taxes, related to
prepayment penalties and the write-off of previously capitalized deferred
financing costs.
 
    On February 18, 1997, the Company filed a registration statement on Form S-3
with the Securities and Exchange Commission related to the proposed sale of up
to 8,500,000 shares of the Company's Common Stock to the public. The Company
expects this offering will be completed early in the second quarter of 1997.
Proceeds from this offering will be used to fund a portion of the purchase price
related to the acquisition discussed above.
 

    The acquisition of APC will be accounted for as a purchase and, accordingly,
APC's assets and liabilities will be recorded at fair values as of the
acquisition date. Following is an unaudited pro forma balance sheet of the
Company, based on preliminary estimates of the allocation of the purchase price,
as if

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To A.O. Smith Corporation:
 
    We have audited the accompanying combined statements of net assets to be
acquired of the Automotive Products Company (a division of A.O. Smith
Corporation--a Delaware corporation) as of December 31, 1995 and 1996, and the
related combined statements of revenues and expenses and cash flows for each of
the three years in the period ended December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
    We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    These financial statements have been prepared to reflect the operations of
A.O. Smith Corporation to be acquired pursuant to the transaction discussed in
Note 1 and are not intended to be a complete presentation of A.O. Smith
Corporation's assets and liabilities, revenues and expenses or cash flows.
 
    In our opinion, the financial statements referred to above present fairly,
in all material respects, the net assets to be acquired of the Automotive
Products Company pursuant to the Asset Purchase Agreement discussed in Note 1 as
of December 31, 1995 and 1996, and the results of its operations and its cash
flows for each of the three years in the period ended December 31, 1996 in
conformity with generally accepted accounting principles.

    Prepaid customer tooling represents costs incurred by the Company in the
development of new tooling used in the manufacture of the Company's products
over the amount of such costs billed to the Company's customers. The Company
receives specific purchase orders for this tooling and is reimbursed by its
customers. Costs incurred are deferred until reimbursed by the customer.
 
    PROPERTY, PLANT AND EQUIPMENT:
 
    Property, plant and equipment are stated at cost. For financial reporting
purposes, depreciation and amortization are provided using the straight-line
method over the following estimated useful lives:
 
<TABLE>
<S>                                                            <C>
                                                               10 to 40
Buildings and improvements...................................  years
Machinery and equipment......................................  5 to 17 years
</TABLE>
 
    Accelerated depreciation methods are used for tax reporting purposes.
 
    Interest of $0.7 million, $0.4 million and $1.7 million was capitalized to
fixed assets under construction during 1994, 1995 and 1996.
 
    Maintenance and repairs are charged to expense as incurred. Major
improvements which extend the useful life of the related item are capitalized
and depreciated. The cost and accumulated depreciation of property, plant and
equipment retired or otherwise disposed of are removed from the related
accounts, and any residual values are charged or credited to income.
 
    CAPITALIZED SOFTWARE COSTS:
 
    Incremental direct costs associated with the customization and
implementation of purchased software are expensed until the Company is
reasonably certain that the specific new system (or substantial revision) will
be completed and will fulfill its intended use. Such costs are then capitalized
and amortized over their estimated useful lives--generally 3 to 10 years.
Training and nonincremental costs incurred in these activities are expensed as
incurred. Unamortized computer software costs were $6.9 million and $16.0
million as of December 31, 1995 and 1996. Amortization of these costs which was
charged to expense amounted to $1.6 million, $0.6 million and $0.7 million
during 1994, 1995 and 1996.

</TABLE>
 
    REVENUE RECOGNITION:
 
    The Company recognizes revenue upon shipment of product to the customer.
 
    FOREIGN CURRENCY TRANSLATION:
 
    For all subsidiaries outside the United States, the Company uses the local
currency as the functional currency. For these operations, assets and
liabilities are translated to U.S. dollars at year-end exchange rates and
weighted average exchange rates are used for revenues and expenses. The
resulting translation adjustments are reflected as a change in the Parent's
investment in the Company. Gains and losses from foreign currency transactions
are included in results of operations.
 
    DERIVATIVES:
 
    As a result of having various foreign operations, the Parent and Company are
exposed to the effect of foreign currency rate fluctuations on the U.S. dollar
value of their foreign operations. Further, the Parent and Company conduct
business in various foreign currencies. To minimize the effect of fluctuating
foreign currencies on its operating results, the Parent has historically entered
into foreign currency forward contracts. The contracts were used to hedge known
foreign currency transactions for both the Parent and the Company on a
continuing basis for periods consistent with the Parent's exposures. The effect
of such transactions as they related to the Company was not material.
 
    INCOME TAXES:
 
    The accompanying financial statements reflect income taxes accounted for
under the liability method, whereby deferred income taxes are recognized at
currently enacted income tax rates to reflect the tax effect of temporary
differences between the financial reporting and tax bases of certain assets and
liabilities.
 
    CHARGES FROM A.O. SMITH:
 
    The Parent has historically provided various services to APC and its other
operating units, including income tax, internal audit, benefits, corporate
technology, legal, strategic and treasury related services. Specific
determination of the costs associated with these services that relate directly
to the Company is not practicable; accordingly, the amounts presented in the
accompanying financial statements related to these

               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
2. SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
services reflect estimates, which management believes were reasonable and
appropriate in the circumstances. Management does not believe that such
estimates differ materially from actual amounts had it been practicable to
specifically identify such actual amounts. The estimated amount of corporate
expenses included in the accompanying combined statements of revenues and
expenses for the years ended December 31, 1994, 1995 and 1996 was $6 million,
$6.5 million and $5 million.
 
    In addition to the above expense reimbursement charges, the accompanying
financial statements reflect charges for the Company's proportionate share of
the Parent's interest expense, allocated based on the relationship of the
Company's net assets to the Parent's total consolidated net assets.
 
    NEW ACCOUNTING PRONOUNCEMENT:
 
    During 1996, the Company adopted the provisions of Statement of Financial
Accounting Standards No. 121, "Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to Be Disposed Of." This statement provides
guidance for determining whether the value of certain long-lived assets,
identifiable intangibles and goodwill has been impaired. The adoption of this
statement had no impact on the Company's financial position or results of
operations.
 
    USE OF ESTIMATES:
 
    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 and
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. Such estimates relate primarily to the carrying amounts of
inventories and customer tooling balances and to the determination of charges
for services provided by the Parent. The ultimate results could differ from
those estimates.
 
3. MAJOR CUSTOMERS:
 
    The Company sells its products directly to automobile manufacturers.
Following is a summary of customers that accounted for a significant portion of
the Company's revenues:

    Receivables from these customers represented 68% and 76% of net accounts
receivable at December 31, 1995 and 1996.
 
4. SALES TO METALSA:
 
    APC sells certain automotive frame components to Metalsa S.A. de C.V., a
Mexican joint venture in which the Parent is an investor. Sales were $11.0
million in 1994, $11.6 million in 1995 and $15.7 million in

1996. Receivables related to the transaction activity were $.8 million, and $1.0
million as of December 31, 1995 and 1996. Such transactions were priced to
approximate fair market value.
 
5. INVESTMENT IN JOINT VENTURE:
 
    In 1995, APC entered into a joint venture to produce certain of its parts in
China. This investment, equal to 60% of the joint venture equity, is accounted
for using the equity method of accounting as a result of the Company's voting
rights and general business restrictions within China. At December 31, 1995 and
1996, the carrying amount of the investment was $3.8 million and $20.6 million
and is included in other assets in the accompanying combined statements of net
assets to be acquired. The carrying amounts of the investment have not exceeded
the Company's equity in the underlying net assets. No income or distributions
were recognized or paid out by the joint venture in 1995 or 1996. Facility
operations are scheduled to begin in early 1997.
 
6. INCOME TAXES:
 
    The Company's results of operations have been historically included in the
consolidated federal income tax returns of A.O. Smith. As a result, all tax
payments were made by A.O. Smith. The provisions for income taxes in the
accompanying combined statements of revenues and expenses for the years ended
December 31, 1994, 1995 and 1996 were computed as if the Company had filed
separate tax returns.
 
    The income tax provision consisted of the following (in thousands):

    RETIREMENT AND BENEFIT PLANS:
 
    Employees of the Company may be eligible to participate in a variety of
retirement and benefit plans that are sponsored by the Company and the Parent.
Participation in these plans is subject to certain eligibility conditions.
 
    The Parent sponsors a qualified noncontributory defined benefit plan which
was established on December 31, 1995 through the merger of its various defined
benefit plans in the United States into one plan. Benefits for salaried
employees are based on the employee's years of service and compensation.
Benefits for hourly employees are generally based on years of service. The
Parent's policy is to contribute amounts which are actuarially determined to
provide sufficient assets to meet future benefit payment requirements consistent
with the funding requirements of federal law and regulations. Plan assets
consist primarily of marketable equities and debt securities. The Company
recognized pension expense of $3.0 million, $5.4 million and $3.3 million during
1994, 1995 and 1996 related to its contributions to this plan. As of December
31, 1996, net plan assets exceeded the projected benefit obligation under the
plan.
 
    The Parent sponsors several defined contribution employee benefit plans for
hourly and salaried personnel in the United States and Canada. Under the plans,
the Company matches employee contributions based upon formulas established in
the plans. Company contributions under these plans for the benefit of Company
employees were $1.4 million during each of 1994, 1995 and 1996.

    POSTRETIREMENT HEALTHCARE:
 
    The Company participates in a defined benefit postretirement plan sponsored
by the Parent which provides medical and life insurance benefits to certain
hourly and salaried employees from retirement to age 65. Salaried employees
retiring after January 1, 1995, are covered by an unfunded defined contribution
plan with benefits based on years of service. Certain hourly employees retiring
after January 1, 1996, will be subject to a maximum annual benefit limit.
Salaried employees hired after December 31, 1993, are not eligible for
postretirement medical benefits.

    The assumed healthcare cost trend rate used in measuring the APBO is 6
percent. The weighted average discount rate used in determining the APBO was 7.5
and 8.0 percent at December 31, 1995 and 1996. If the healthcare cost trend rate
were increased by 1 percent, the APBO at December 31, 1996 would increase by
$1.8 million and net periodic postretirement benefit cost for 1996 would
increase $.2 million.

8. ACQUISITION BY TOWER AUTOMOTIVE, INC.:
 
    On January 27, 1997, a wholly owned subsidiary of R.J. Tower agreed to
acquire and assume substantially all of the assets and liabilities of the
Company. Terms of the agreement provided for the payment of cash consideration
of approximately $625 million, subject to certain adjustments. The Acquisition
is expected to be completed during the second quarter of 1997. Subsequent to the
Acquisition, the operations of the Company will be continued by R.J. Tower on a
basis substantially consistent with that which existed prior to the Acquisition.
The Acquisition will be accounted for as a purchase and, accordingly, the
Company's assets and liabilities will be recorded at fair value as of the
acquisition date.

Restated Certificate of Incorporation of the Registrant provide for
indemnification of its directors and officers to the fullest extent permitted by
applicable law.
 
    The form of Underwriting Agreement attached hereto as Exhibit 1.1, which
provides for, among other things, the Registrant's sale to the Underwriters of
the securities being registered herein, will obligate the Underwriters to

ITEM 17.  UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities
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 the initial bona fide offering thereof.
 
    (b) Insofar as indemnification for liabilities arising under the Securities
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 Securities 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 Securities Act and will be governed by the final
adjudication of such issue.
 
    (c) The undersigned Registrant hereby undertakes that:
 
        (1) For purposes of determining any liability under the Securities 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 Securities Act shall be deemed to be a part of this
    Registration Statement as of the time it was declared effective.
 
        (2) For purposes of determining any liability under the Securities 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.
