                                  THE COMPANY
 
    The Company  is a  leading  remanufacturer and  distributor of  drive  train
products  used in the aftermarket repair of passenger cars and light trucks. The
Company's  principal  products  include  remanufactured  transmissions,   torque
converters  and engines, as well as remanufactured  and new parts for the repair
of automotive  drive  train  and  engine  assemblies.  The  Company's  principal
customers include: (i) independent transmission rebuilders, general repair shops
and  distributors  (the  "Independent  Aftermarket");  (ii)  original  equipment
manufacturers ("OEMs"), principally  Chrysler, for use  as replacement parts  by
their dealers; and (iii) retail automotive parts stores. The Company believes it
is  uniquely positioned within the highly fragmented aftermarket for drive train
products as a result  of its extensive product  line, diverse customer base  and
broad  geographic presence, with  43 distribution centers  throughout the United
States and Canada.
 
    The automotive  aftermarket in  North America,  which consists  of sales  of
parts  and  services  for  vehicles  after  their  original  purchase,  has been
noncyclical and has generally experienced steady growth over the past ten years,
unlike the  market for  new  vehicle sales.  Between  1985 and  1995,  estimated
industry-wide   revenue   for   the   automobile   aftermarket   increased  from
approximately $126  billion  to $170  billion.  This consistent  growth  is  due
principally  to the increase in the number  of vehicles in operation that are in
the prime repair age of four to 12 years and the increase in the average  number
of  miles driven annually per vehicle.  The Company competes specifically in the
aftermarket segment for automotive transmissions, engines and other drive  train
related products, which represents more than $7 billion of the entire automotive
aftermarket.  The  Company  believes that  within  this segment  the  market for
remanufactured drive train products has grown faster than the overall automotive
aftermarket.
 
    The Company  was  organized  in  1994  by  Aurora  Capital  Partners  and  a
management  team  led by  William A.  Smith  to combine  the businesses  of four
existing companies serving  the drive train  remanufacturing market. Since  that
time  the  Company  has  grown  both  internally  and  through  four  additional
acquisitions completed during  1995 and  1996. The Company  and its  predecessor
companies  have achieved  compound annual growth  in revenue of  37.5% from 1992
through March 31, 1996  (29.9% if the Company's  1995 and 1996 acquisitions  are
excluded).  The Company believes the key elements of its success are the quality
and breadth  of its  product  offerings and  the  Company's emphasis  on  strong
customer  relationships, promoted  by strong  technical support,  rapid delivery
time, innovative product development and  competitive pricing. In addition,  the
Company  has benefited from the  increasing use of remanufactured transmissions,
engines and other parts for aftermarket repairs as the industry recognizes  that
remanufacturing  provides a higher quality, lower cost alternative to rebuilding
the assembly or replacing it with a new assembly manufactured by an OEM.
 
    The Company's  strategy is  to achieve  growth both  internally and  through
strategic  acquisitions. The Company intends to expand its existing business by:
(i) increasing penetration of its current  customer base; (ii) gaining new  OEM,
Independent Aftermarket and retail customers; and (iii) introducing new products
to  both existing  and new customers.  Strategic acquisitions have  also been an
important  element  in  the  Company's  historical  growth.  The  Company   sees
significant  opportunities to  continue expanding its  customer base, geographic
presence  and  product  offerings  through  additional  strategic  acquisitions,
particularly
 
                                       4
<PAGE>
among   companies  serving   the  highly   fragmented  Independent  Aftermarket.
Management believes  that future  acquisitions  will enable  it to  enhance  the
Company's  revenues  and  profitability  by  expanding  the  Company's  existing
distribution base, increasing the range  of products sold through the  Company's
distribution  network  and  realizing  economies  of  scale  in  areas including
purchasing, administration and inventory management.
 
HISTORY; REORGANIZATION
 
    ATC  and  its  sole  stockholder,  Aftermarket  Technology  Holdings   Corp.
("Holdings"),  were incorporated under the laws of  Delaware in July 1994 at the
direction of Aurora Capital Partners L.P. ("ACP") to acquire Aaron's  Automotive
Products,  Inc.  ("Aaron's"),  H.T.P.,  Inc.  ("HTP"),  Mamco  Converters,  Inc.
("Mamco")  and   RPM   Merit,   Inc.   ("RPM")   (collectively,   the   "Initial
Acquisitions"). Aaron's, HTP, Mamco and RPM as they existed prior to the Initial
Acquisitions  are  hereinafter  collectively  referred  to  as  the "Predecessor
Companies."  Subsequent  to  the  Initial  Acquisitions,  the  Company  acquired
Component  Remanufacturing Specialists, Inc. ("CRS") and Mascot Truck Parts Inc.
("Mascot") in June 1995, and King-O-Matic Industries Limited ("King-O-Matic") in
September 1995  (collectively, the  "1995  Acquisitions") and  Tranzparts,  Inc.
("Tranzparts")  in April  1996 (the  "1996 Acquisition"  and, together  with the
Initial  Acquisitions  and  the  1995  Acquisitions,  the  "Acquisitions").  ATC
conducts all of its operations through its wholly-owned subsidiaries and each of
their respective subsidiaries.
 
    Simultaneous  with the  consummation of this  offering of  Common Stock (the
"Offering"), Holdings will be merged  into ATC (the "Reorganization"). Upon  the
effectiveness  of such merger,  each outstanding share  of Holdings Common Stock
will be converted into         shares of ATC Common Stock, and each  outstanding
share  of  Holdings  Redeemable  Exchangeable  Cumulative  Preferred  Stock (the
"Holdings Preferred  Stock") will  be converted  into the  right to  receive  an
amount  in cash  equal to $100.00  plus an amount  in cash equal  to accrued and
unpaid dividends  to  the  date  of the  Reorganization  (the  "Preferred  Stock
Reorganization  Consideration"). As  of June  30, 1996,  the aggregate Preferred
Stock Reorganization  Consideration  would  be approximately  $24  million.  See
"Reorganization."
 
    The  principal executive offices  of the Company are  located at 33309 First
Way South, Suite A-206, Federal Way, Washington 98003, and its telephone  number
is (206) 838-0346.

                                  RISK FACTORS
 
    PROSPECTIVE  INVESTORS SHOULD  CAREFULLY CONSIDER  THE SPECIFIC  FACTORS SET
FORTH BELOW AS WELL AS THE OTHER INFORMATION INCLUDED IN THIS PROSPECTUS  BEFORE
DECIDING TO INVEST IN THE COMMON STOCK OFFERED HEREBY.
 
    DEPENDENCE  ON  SIGNIFICANT  CUSTOMER.    The  Company's  largest  customer,
Chrysler, accounted for  approximately $67.6  million and $23.7  million of  the
Company's  combined net sales for the year ended December 31, 1995 and the three
months ended March  31, 1996,  respectively, or approximately  35.4% and  36.9%,
respectively,  of the  Company's net sales  for such periods.  No other customer
accounted for more than  10% of the  Company's net sales  during either of  such
periods.  Chrysler,  like  other  North American  OEMs,  generally  requires its
dealers using remanufactured products to use only those from approved suppliers.
Although  the  Company  is  currently  the  only  factory-approved  supplier  of
remanufactured  transmissions to Chrysler, Chrysler is not obligated to continue
to purchase  the Company's  products and  there  can be  no assurance  that  the
Company  will be able to maintain or increase the level of its sales to Chrysler
or that Chrysler will  not approve other suppliers  in the future. In  addition,
within  the last  two years Chrysler  reduced its standard  new vehicle warranty
from seven years/70,000 miles to three years/36,000 miles and could implement  a
shorter  warranty  in the  future.  Any such  action  could have  the  effect of
reducing the amount of warranty work performed by Chrysler dealers. An extended,
substantial decrease  in orders  from  Chrysler would  have a  material  adverse
effect  on  the  Company.  See  "Business  --  Marketing  and  Distribution; OEM
Customers."
 
    SHORTAGE OF TRANSMISSION CORES AND COMPONENT PARTS.  In its  remanufacturing
operations,  the  Company obtains  used transmissions,  hard parts,  engines and
related components,  commonly known  as  "cores," which  are sorted  and  either
placed  into immediate  production or stored  until needed. The  majority of the
cores remanufactured by the  Company are obtained  from customers as  trade-ins.
The  ability to obtain cores of the types  and in the quantities required by the
Company is  critical  to  the  Company's  ability  to  meet  demand  and  expand
production.  With the increased acceptance  in the aftermarket of remanufactured
assemblies, the demand  for cores  has increased. The  Company periodically  has
experienced  situations in  which the inability  to obtain  sufficient cores has
limited its ability to accept all of the orders available to it. As part of  its
expanding relationship with Chrysler and in response to the periodic shortage of
cores,  in 1994  the Company  established at  Chrysler's request  a central core
return center  for all  of  Chrysler's transmission  product lines  and  certain
engine  product lines.  The operation  of this  facility enables  the Company to
manage more effectively the  tracking and return of  cores for Chrysler and  its
United  States dealers.  There can  be no  assurance that  the Company  will not
experience core shortages in the future. If the Company were to experience  such
a shortage, it could have a material adverse effect on the Company.
 
    Certain   component  parts  required  in  the  remanufacturing  process  are
manufactured by Chrysler and the Company's other OEM customers. The Company  has
experienced  shortages of such component parts from time to time in the past and
future shortages  could  have a  material  adverse  effect on  the  Company.  In
addition,  Chrysler's labor  contract with  the United  Auto Workers  expires in
September 1996. A prolonged strike could materially impair Chrysler's ability to
provide  the   Company  with   necessary  component   parts  for   transmissions
remanufactured for use in Chrysler vehicles.
 
    ABILITY TO ACHIEVE AND MANAGE GROWTH.  An important element in the Company's
growth  strategy is the acquisition  and integration of complementary businesses
in order to  broaden its  product offerings,  capture market  share and  improve
profitability.  There  can be  no assurance  that  the Company  will be  able to
identify or reach mutually agreeable terms with acquisition candidates, or  that
the  Company  will  be  able  to  manage  additional  businesses  profitably  or
successfully integrate  such  additional  businesses into  the  Company  without
substantial  costs, delays or other problems.  Acquisitions may involve a number
of special  risks,  including:  initial reductions  in  the  Company's  reported
operating  results; diversion of  management's attention; unanticipated problems
or legal  liabilities; and  a possible  reduction in  reported earnings  due  to
amortization  of acquired  intangible assets. Some  or all of  these items could
have a material adverse effect  on the Company. There  can be no assurance  that
businesses acquired in the future will achieve sales and
 
                                       9
<PAGE>
profitability  that justify the  investment therein. In  addition, to the extent
that consolidation  becomes  more prevalent  in  the industry,  the  prices  for
attractive  acquisition  candidates  may increase  to  unacceptable  levels. See
"Business -- Business Strategy -- External Growth."
 
    In addition to growth through acquisitions, the Company plans to expand  its
existing operations by broadening its product lines and increasing the number of
its  distribution centers in the  United States. There can  be no assurance that
any new product  lines introduced by  the Company will  be successful, that  the
Company  will manage successfully the start-up  and marketing of new products or
that additional  distribution  centers will  be  integrated into  the  Company's
existing operations or will be profitable. See "Business -- Business Strategy --
Internal Growth."
 
    INDEBTEDNESS  AND LIQUIDITY.   The  Company had  outstanding indebtedness of
$163.9 million at March 31, 1996, bearing interest at a weighted average rate of
11.7%, and the Company's ratio  of earnings to fixed  charges for the 12  months
then ended was 2.3 to 1. After giving effect to the consummation of the Offering
and  the anticipated application of the  net proceeds therefrom (after deducting
the  underwriting  discount  and  estimated  expenses  of  the  Offering),   the
consolidated  indebtedness  of the  Company at  March 31,  1996 would  have been
$123.4 million and the Company's ratio of  earnings to fixed charges for the  12
months  then  ended  would  have been  3.1  to  1. The  level  of  the Company's
consolidated indebtedness could  have important consequences  to the holders  of
Common  Stock,  including  the  following:  (i)  a  substantial  portion  of the
Company's cash  flow  from  operations  must be  dedicated  to  the  payment  of
principal  of and  interest on  its indebtedness and  will not  be available for
other purposes;  (ii) the  ability of  the Company  to obtain  financing in  the
future   for   working  capital   needs,  capital   expenditures,  acquisitions,
investments, general  corporate purposes  or other  purposes may  be  materially
limited  or impaired; (iii)  the Company's level of  indebtedness may reduce its
flexibility to  respond to  changing business  and economic  conditions or  take
advantage  of business opportunities that may arise; and (iv) the ability of the
Company to pay dividends  is restricted. See "Dividend  Policy." Any default  by
the  Company with respect  to its outstanding indebtedness,  or any inability on
the part of  the Company to  obtain necessary liquidity,  would have a  material
adverse effect on the Company. See "Use of Proceeds" and "Description of Certain
Indebtedness."
 
    DEPENDENCE  ON KEY  PERSONNEL.   The Company  is dependent  on the continued
services of its  management team, including  William A. Smith,  Chairman of  the
Board,  President and Chief  Executive Officer. Mr.  Smith, Wesley N. Dearbaugh,
President and General Manager of Independent Aftermarket, and the presidents  of
the  operating  subsidiaries  have an  average  of  22 years  experience  in the
automotive aftermarket industry. Although the Company believes it could  replace
key  employees in  an orderly fashion  should the  need arise, the  loss of such
personnel could have a material adverse effect on the Company.
 
    ENVIRONMENTAL MATTERS.  The Company is subject to various evolving  federal,
state,  local and  foreign environmental  laws and  regulations governing, among
other things,  emissions  to  air,  discharge  to  waters  and  the  generation,
handling,  storage,  transportation,  treatment  and disposal  of  a  variety of
hazardous and non-hazardous  substances and wastes.  These laws and  regulations
provide  for  substantial  fines  and  criminal  sanctions  for  violations. The
operation of  automotive  parts remanufacturing  plants  involves  environmental
risks.
 
    The  company from which  RPM acquired its assets  (the "Prior RPM Company"),
has been identified by  the United States  Environmental Protection Agency  (the
"EPA")  as one  of the  many potentially  responsible parties  for environmental
liabilities associated with  a "Superfund"  site located  in the  area of  RPM's
former  manufacturing  facilities and  current  distribution facility  in Azusa,
California. The EPA has preliminarily estimated that it will cost  approximately
$47 million to construct and approximately $4 million per year for an indefinite
period  to operate an interim remedial  groundwater pumping and treatment system
for a part  of the subregion  of the  Superfund site within  which RPM's  former
manufacturing  facilities and current distribution facility, as well as those of
many other potentially responsible parties, are located. The actual cost of this
remedial action  could vary  substantially from  this estimate,  and  additional
costs  associated with the Superfund site are likely to be assessed. The Company
has  significantly  reduced  its  presence  at  the  site  and  has  moved   all
manufacturing  operations  off-site. Since  July 1995,  the Company's  only real
property interest in this site has been the lease of a 6,000 square foot storage
and distribution facility. The RPM
 
                                       10
<PAGE>
acquisition agreement and the leases pursuant to which the Company leased  RPM's
facilities  after the Company acquired the assets of RPM (the "RPM Acquisition")
expressly  provide  that  the  Company  did  not  assume  any  liabilities   for
environmental conditions existing on or before the RPM Acquisition, although the
Company  could  become responsible  for  these liabilities  under  various legal
theories. The Company is indemnified against any such liabilities by the  seller
of RPM as well as the Prior RPM Company shareholders. There can be no assurance,
however,  that  the  Company  would  be able  to  make  any  recovery  under any
indemnification provisions.  Since the  RPM Acquisition,  the Company  has  been
engaged  in negotiations with the  EPA to settle any  liability that it may have
for this site. The Company believes, although there can be no assurance, that it
will not  incur  any  material  liability as  a  result  of  these  pre-existing
environmental conditions.
 
    In  connection with the Initial  Acquisitions, the Company conducted certain
investigations of Aaron's, RPM's, HTP's  and Mamco's facilities (in addition  to
the  Prior RPM Company's Azusa facilities)  and their compliance with applicable
environmental laws. The Company  conducted similar investigations in  connection
with  its subsequent acquisitions  of CRS, Mascot,  King-O-Matic and Tranzparts.
The  investigations,  which  included  "Phase  I"  assessments  by   independent
consultants of all manufacturing and certain distribution facilities, found that
certain remedial, reporting and other regulatory requirements, including certain
waste  management procedures, were not or may  not have been satisfied. Based in
part on the investigations conducted, and the indemnification provisions of  the
agreements  entered into  in connection  with the  Initial Acquisitions  and the
Company's subsequent acquisitions, the Company  believes, although there can  be
no  assurance, that its liabilities relating to these environmental matters will
not have a  material adverse effect,  individually or in  the aggregate, on  the
Company. See "Business -- Environmental."
 
    COMPETITION.    The automotive  aftermarket  for transmissions,  engines and
other drive train products  is highly fragmented  and highly competitive.  There
can  be  no assurance  that  the Company  will  compete successfully  with other
companies in its industry segment, some of which are larger than the Company and
have greater  financial and  other resources  available to  them than  does  the
Company.
 
    CONTROL  OF THE  COMPANY; ANTI-TAKEOVER MATTERS.   Upon  consummation of the
Offering,  the  Company  will  be  indirectly  controlled  by  ACP,  which  will
beneficially  own in the aggregate approximately     % of the outstanding Common
Stock. Therefore, ACP will be able to elect all of the directors of the  Company
and  to approve or  disapprove any matter  submitted to a  vote of the Company's
stockholders. As a result of ACP's substantial ownership interest in the  Common
Stock,  it may  be more difficult  for a third  party to acquire  the Company. A
potential buyer would likely be deterred from any effort to acquire the  Company
absent  the consent of ACP  or its participation in  the transaction. Two of the
three managing directors  of ACP are  directors of the  Company. The  Indentures
governing  the  Senior Notes  contain provisions  that would  allow a  holder to
require the Company  to repurchase such  holder's Senior Notes  at a cash  price
equal  to 101% of the principal  amount thereof, together with accrued interest,
upon the occurrence of  a change of  control of the  Company. See "Ownership  of
Voting Securities" and "Description of Certain Indebtedness."
 
    In  addition, the  Company's Board  of Directors  is authorized,  subject to
certain limitations prescribed  by law, to  issue up to               shares  of
preferred  stock in one or  more classes or series  and to fix the designations,
powers,  preferences,  rights,  qualifications,  limitations  or   restrictions,
including  voting rights, of those shares without  any further vote or action by
stockholders. The rights of the holders of Common Stock will be subject to,  and
may  be adversely affected by, the rights  of the holders of any preferred stock
that may  be  issued in  the  future. The  issuance  of preferred  stock,  while
providing  flexibility  in  connection  with  possible  acquisitions  and  other
corporate transactions, could have the effect of making it more difficult for  a
third  party  to acquire  a  majority of  the  outstanding voting  stock  of the
Company. The Company has no current plans to issue shares of preferred stock.
 
    POSSIBLE EFFECT ON  SHARE PRICE OF  SHARES ELIGIBLE FOR  FUTURE SALE.   Upon
consummation  of the Offering, the  Company will have           shares of Common
Stock outstanding, of which  approximately           shares will be  "restricted
securities"  within the meaning  of Rule 144 ("Rule  144") promulgated under the
Securities Act of 1933, as amended (the  "Securities Act"), and may not be  sold
without   registration  under  the  Securities  Act  unless  an  exemption  from
registration is available. Each of the Company's current
 
                                       11
<PAGE>
stockholders and certain holders of the Company's outstanding options have  been
granted  certain "piggyback" registration  rights with respect  to the shares of
Common Stock owned by them  or to be issued to  them. However, the Company  will
agree  not to offer, pledge, sell, contract to sell, sell any option or contract
to purchase,  purchase an  option, right  or warrant  to purchase  or  otherwise
transfer  or dispose of any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common  Stock or enter into any swap  or
other  arrangement that transfers  to another, in  whole or in  part, any of the
economic consequences of ownership of Common Stock for a period of 180 days from
the date of this Prospectus without the prior written consent of Morgan  Stanley
&  Co.  Incorporated. Each  of  the Company's  current  stockholders, directors,
executive officers and warrant holders will enter into or is bound by a  similar
agreement.  No predictions  can be made  as to  the effect, if  any, that public
sales of shares or the availability of  shares for sale will have on the  market
price  prevailing from time to time.  Nevertheless, sales of substantial amounts
of the Common Stock in the public market, particularly by directors and officers
of the Company, or  the perception that  such sales could  occur, could have  an
adverse effect on the market price of the Common Stock. See "Shares Eligible for
Future Sale."
 
    DILUTION.   The initial public offering price per share of Common Stock will
exceed the net tangible book value  per share of Common Stock. Accordingly,  the
current stockholders of the Company will experience an immediate appreciation in
the  net tangible book value of their  equity investment in the Company, and the
purchasers of Common Stock will experience immediate and substantial dilution in
the net  tangible book  value of  their  equity investment  in the  Company.  In
addition,  there  will be  outstanding after  the  consummation of  the Offering
options and warrants to purchase approximately         shares of Common Stock at
exercise prices ranging from $    to $    per share, the exercise of which would
cause further dilution to new investors. See "Dilution."
 
    ABSENCE OF A PUBLIC MARKET; DETERMINATION  OF OFFERING PRICE.  Prior to  the
Offering,  there has been  no public market for  the Common Stock. Consequently,
the initial  public  offering  price will  be  determined  through  negotiations
between  the Company and representatives of the Underwriters. See "Underwriters"
for factors to be considered in  determining the initial public offering  price.
There  can be no  assurance that a  regular trading market  for the Common Stock
will develop after the Offering or,  if developed, that a public trading  market
can  be  sustained.  The  initial public  offering  price  will  not necessarily
reflect, and may be higher than, the market price of the Common Stock after  the
Offering.
 
                                       12
<PAGE>
                                 REORGANIZATION
 
    Simultaneous  with the consummation of the Offering, Holdings will be merged
into ATC.  Upon the  effectiveness of  such merger,  each outstanding  share  of
Holdings  Common Stock will be converted into               shares of ATC Common
Stock and each outstanding share of  Holdings Preferred Stock will be  converted
into  the right to receive the  Preferred Stock Reorganization Consideration. As
of June  30, 1996  the aggregate  Preferred Stock  Reorganization  Consideration
would  be approximately  $24 million. Holdings'  1994 Stock  Incentive Plan will
become ATC's plan (the "Stock  Incentive Plan"), and outstanding employee  stock
options  that were  issued by  Holdings pursuant  to the  Holdings plan  will be
converted into options to purchase  ATC Common Stock. Outstanding warrants  that
were  issued by Holdings will be converted  into warrants to purchase ATC Common
Stock on the same exercise ratio as the ratio applicable to the Holdings  Common
Stock.
 
                                USE OF PROCEEDS
 
    The  net proceeds to the Company from the sale of the         shares offered
hereby are estimated to be approximately $69 million (approximately $79  million
if  the Underwriters' over-allotment option is exercised in full), based upon an
assumed offering  price  of  $       per share  and  after  deducting  estimated
underwriting discounts and offering expenses.
 
    Approximately $46.8 million of the net proceeds of the Offering will be used
by  the  Company to  redeem  $40,000,000 in  aggregate  principal amount  of the
Company's Senior  Notes at  a redemption  price of  112% plus  accrued  interest
thereon (assuming a June 30, 1996 redemption date). Approximately $24 million of
the  net  proceeds of  the  Offering will  be  used by  the  Company to  pay the
aggregate Preferred Stock Reorganization Consideration.
 
    Any remaining net proceeds will be used by the Company for general corporate
purposes. Pending  such  application, the  Company  intends to  invest  the  net
proceeds  from this  Offering in  investment-grade, short-term, interest-bearing
securities. If the net proceeds from the Offering are not sufficient to fund the
intended redemption of Senior Notes and payment of the aggregate Preferred Stock
Reorganization Consideration, the balance will be paid from cash on hand.
 
                                DIVIDEND POLICY
 
    The Company has not paid cash dividends on its Common Stock to date. Because
the Company currently intends  to retain any earnings  to provide funds for  the
operation  and expansion of its business and  for the servicing and repayment of
indebtedness, the Company does  not intend to pay  cash dividends on the  Common
Stock  in  the foreseeable  future. Furthermore,  as a  holding company  with no
independent operations, the ability of the Company to pay cash dividends will be
dependent upon the receipt of dividends or other payments from its subsidiaries.
Under the terms of the Indentures governing the Senior Notes, the Company is not
permitted to pay  any dividends  on the  Common Stock  unless certain  financial
ratio  tests are satisfied. In addition, the Company's revolving credit facility
contains certain covenants which,  among other things,  prohibit the payment  of
dividends by the Company. See "Management's Discussion and Analysis of Financial
Condition  and Results  of Operations --  Liquidity and  Capital Resources." Any
determination to pay cash dividends on the Common Stock in the future will be at
the sole discretion of the Company's Board of Directors.

(1)  In addition, the Company had  approximately $26 million available under its
    $30 million revolving credit facility as of March 31, 1996.
 
(2) Consists of Holdings Preferred Stock. See "Recapitalization."
 
(3) Does not give effect  to the issuance of  shares reserved for issuance  upon
    the exercise of outstanding warrants and employee stock options. See "Shares
    Eligible for Future Sale."
 
(4)  The 12%  Senior Notes  are subject to  a redemption  premium. This premium,
    combined with the related unamortized debt issuance costs, will be  expensed
    as  an extraordinary item at  the time of redemption.  As of March 31, 1996,
    the extraordinary item  would have  been $3.4  million after  the effect  of
    taxes.

                                    DILUTION
 
    The  pro forma net tangible  book value of the Company  as of March 31, 1996
was $(112.6) million, or $(     ) per share  of Common Stock. Net tangible  book
value  per share is determined by dividing the tangible net worth of the Company
(total assets less  intangible assets and  total liabilities) by  the number  of
common  shares outstanding, after giving effect  to the payment of the Preferred
Stock Reorganization Consideration. Without taking  into account any changes  in
such  net tangible book value after March 31, 1996, other than to give effect to
the sale of the            shares of Common Stock  at an assumed initial  public
offering  price of $      per share and  the anticipated application  of the net
proceeds therefrom, pro forma net tangible book value of the Company as of March
31, 1996 would have  been approximately $(45.6) million,  or $(     ) per  share
(after  giving effect to the  use of the net  proceeds from this Offering). This
represents an immediate increase in net tangible book value of $    per share to
current ATC stockholders  and an immediate  dilution of $      per share to  new
stockholders.  Dilution to new stockholders is determined by subtracting the net
tangible book  value per  share  after this  Offering  from the  initial  public
offering  price  per  share.  The following  table  illustrates  this  per share
dilution.

(1) The combined financial statements for  the seven months ended July 31,  1994
    include  the operations of the Predecessor  Companies up to their respective
    acquisition dates; operations  for RPM between  July 20, 1994  and July  31,
    1994  and for the other three Predecessor  Companies for August 1st and 2nd,
    1994 are not significant. All material transactions between the  Predecessor
    Companies have been eliminated.
 
(2)  Two of the Predecessor Companies elected  to be taxed as S Corporations for
    all periods through consummation of the Initial Acquisitions; therefore, for
    federal and state income tax purposes, any income or loss generally was  not
    taxed  to these companies but was reported by their respective stockholders.
    A pro forma  provision for taxes  based on income  reflecting the  estimated
    provision  for federal and state income taxes which would have been provided
    had these companies been C Corporations and included in consolidated returns
    with the Company  is as  follows: $2,304, $3,036  and $7,334  for the  years
    ended  December 31,  1991, 1992 and  1993, respectively, and  $7,004 for the
    seven months ended July 31, 1994.

    the computation of pro forma net income per share.

    Tranzparts prior  to  such  subsidiaries' respective  acquisitions  and  any
    capital expenditures made in connection with such acquisitions.
 
(5)  Includes deferred tax liabilities of  $1,438, $3,478 and $3,474 at December
    31, 1994 and 1995 and March 31, 1996, respectively.

         NOTES TO UNAUDITED PRO FORMA CONSOLIDATED STATEMENTS OF INCOME
 
     (1) Includes the historical operations of the acquired businesses prior  to
their acquisition by the Company. Accordingly, included in these amounts are CRS
and  Mascot  for  the  five  months  ended  June  1,  1995  and  June  6,  1995,
respectively, King-O-Matic for  the eight  months ended September  12, 1995  and
Tranzparts for the year ended December 31, 1995.
 
     (2)  As adjusted to give  effect to the anticipated  application of the net
proceeds from the Offering as if the  Offering had occurred at the beginning  of
the  respective  periods.  Amounts  do  not  reflect  the  impact  of  the early
redemption  premium  on  the  Senior  Notes  that,  combined  with  the  related
unamortized  debt issuance costs,  will be expensed as  an extraordinary item at
the time of redemption. As of March 31, 1996, the extraordinary item would  have
been $3.4 million after the effect of taxes.
 
     (3)  Prior to its acquisition by the Company, one of the acquired companies
reduced its inventory reserve to state inventory  at its fair value at the  time
of  the acquisition. Such amount  would have been reflected  as a purchase price
adjustment on January 1, 1995, and  accordingly, is excluded from the pro  forma
results for the period.
 
     (4)  Adjusts the compensation  of the former  owner of one  of the acquired
companies to the amount payable under his employment agreement entered into with
the Company at the time of the acquisition.
 
     (5) Reflects the revised rental payments on facilities based upon the lease
agreements signed at the time of the acquisition.
 
     (6) Prior to its acquisition by the Company, one of the acquired  companies
reduced  its  bad debt  reserve  to reflect  estimated  net realizable  value of
receivables at  the  time  of  the acquisition.  Such  amount  would  have  been
reflected as a purchase price adjustment on January 1, 1995, and accordingly, is
excluded from the pro forma results for the period.
 
     (7)  Reflects additional  amortization expense  for the  acquired companies
from the beginning of the period through the respective acquisition date.
 
     (8) Reflects additional interest expense on debt issued in connection  with
the acquisitions, as if the issuance had been consummated as of the beginning of
the  periods presented. Amount includes $89,000 of debt issuance costs amortized
over the life of the related debt.
 
     (9) Eliminates interest on the Senior  Notes that are assumed to have  been
redeemed.
 
    (10) Eliminates interest on debt not assumed in the acquisitions.
 
    (11)  Reflects the adjustment of  income taxes as a  result of the pro forma
adjustments described in these  Notes and the additional  taxes that would  have
been expensed had certain acquired companies been taxed as C Corporations rather
than S Corporations.
 
    (12)  Reflects  additional income  taxes resulting  from the  adjustment for
interest expense.
 
    (13) Eliminates  gain  on sale  to  former owner  of  a building  which  was
subsequently leased to the Company.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
OVERVIEW
 
The  following  discussion  should  be read  in  conjunction  with  the Combined
Financial Statements of the Predecessor Companies and the Consolidated Financial
Statements  of  the  Company  and  notes  thereto  included  elsewhere  in  this
Prospectus.  The  Combined  Financial Statements  of  the  Predecessor Companies
represent the combination  of the  historical financial statements  of the  four
separate businesses of the Predecessor Companies.
 
    The  Company's  revenues  are  generated through  the  sale  of  drive train
products used in the automotive aftermarket  repair of passenger cars and  light
trucks.  Since its  formation, the Company  has benefited from  a combination of
internal and acquisition-related revenue  growth. The Company achieved  compound
annual growth in revenue of 37.5% from 1992 through March 31, 1996 (29.9% if the
1995 and 1996 Acquisitions are excluded).
 
    The  Company's  revenues  from sales  to  Independent  Aftermarket customers
increased by 46.3% from  $58.5 million to $85.6  million between 1992 and  1995.
This  growth was  due to geographic  expansion through  addition of distribution
centers, a broadened  product line, enhanced  customer service, effective  sales
efforts  and acquisitions.  During the same  period, revenues from  sales to OEM
customers increased 407.7% from $16.8 million to $85.3 million due to  increased
sales  to  existing  customers,  including Chrysler,  and  the  addition  of new
customers. Revenues from sales to retail automotive parts stores increased  from
virtually none in 1992 to $19.8 million in 1995.
 
    The  primary components of the Company's cost  of goods sold are the cost of
cores and component  parts, labor  costs and  overhead. While  certain of  these
costs  have fluctuated as a percentage of sales over time, cost of goods sold as
a percentage  of sales  has remained  relatively flat  from 1992  through  1995.
Selling,  general  and  administrative ("SG&A")  expenses  consist  primarily of
salaries,  commissions,   rent,   marketing  expenses   and   other   management
infrastructure  expenses. SG&A expenses  as a percentage  of sales declined from
23.2% in  1993 to  20.5% in  1995 principally  due to  the effect  of  spreading
certain fixed costs over a larger sales base.
 
    The  Company regularly evaluates strategic  acquisition opportunities in the
automotive aftermarket business and expects to continue to do so in the future.
 
RESULTS OF OPERATIONS
 
    The following table sets forth certain financial statement data expressed in
millions of dollars and as a percentage of net sales. The pro forma statement of
income for the  year ended  December 31,  1994 reflects  the combined  financial
statements  for the seven months ended July 31, 1994 for Aaron's, HTP, Mamco and
RPM, and the  consolidated operations  of these  companies for  the five  months
ended  December 31, 1994. Pro forma expense adjustments were made to reflect the
Initial Acquisitions as if they had occurred on January 1, 1994.

for the three month period ended March 31, 1996 included $12.3 million from CRS,
Mascot  and King-O-Matic which were  acquired on June 1,  1995, June 9, 1995 and
September 12, 1995, respectively.
 
    Net sales  of remanufactured  transmissions increased  by $15.7  million  or
94.0%,  from $16.7 million  for the three  month period ended  March 31, 1995 to
$32.4 million for the three month period ended March 31, 1996. This increase was
due primarily two factors: remanufactured transmission sales of $7.8 million  to
foreign  OEMs generated by  CRS, and an  increase in remanufactured transmission
sales to Chrysler of  $6.6 million or  39.8%, from $16.6  million for the  three
month  period ended March 31,  1995 to $23.2 million  for the three month period
ended March 31, 1996.
 
    Net sales of remanufactured engines  increased 68.2%, from $4.4 million  for
the  three month period ended March 31, 1995 to $7.4 million for the three month
period ended March 31,  1996. This increase was  due primarily to a  significant
expansion  of  the  Company's  customer  base  in  the  retail  chain  store and
independent aftermarkets.
 
    Net sales  of repair  kits and  hard parts  and other  drive train  products
increased  $4.8 million or 24.6%, from $19.5  million for the three month period
ended March 31, 1995 to $24.3 million for the three month period ended March 31,
1996. This increase was  primarily due to the  opening of five new  distribution
centers during the first quarter of 1995 and the acquisition of King-O-Matic.
 
    GROSS  PROFIT.   Gross profit  as a percentage  of net  sales increased from
38.4% for the three  month period ended  March 31, 1995 to  40.2% for the  three
month  period ended March  31, 1996. The  increase was primarily  due to greater
absorption of overhead costs resulting from higher production and sales volumes.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net sales,
SG&A expenses decreased from  19.7% for the three  month period ended March  31,
1995  to 19.5% for  the three month  period ended March  31, 1996. However, SG&A
expenses increased in  absolute dollars from  $8.0 million for  the three  month
period  ended March 31, 1995 to $12.5 million for three month period ended March
31, 1996, representing  an increase of  $4.5 million or  56.3%. The increase  in
SG&A   expenses  was  due  largely  to  the  acquisition  of  CRS,  Mascot,  and
King-O-Matic. Other significant  factors contributing  to the  increase in  SG&A
expenses  included the relocation and upgrade of RPM's main facilities in Rancho
Cucamonga, California, and the new manufacturing plant in Joplin, Missouri.
 
    AMORTIZATION OF  INTANGIBLE  ASSETS.    Amortization  of  intangible  assets
increased  $0.2  million for  the three  month  period ended  March 31,  1996 as
compared to the three month period ended March 31, 1995 reflecting the  increase
in  intangible assets  that occurred  as a  result of  the acquisitions  of CRS,
Mascot and King-O-Matic.
 
    INCOME FROM OPERATIONS.   Principally as a result  of the factors  described
above,  income from operations  increased from $6.9 million  for the three month
period ended March 31, 1995  to $12.4 million for  the three month period  March
31, 1996.
 
    INTEREST  EXPENSE (INCOME),  NET.   Interest expense  increased $1.4 million
from $3.5  million for  the three  month period  ended March  31, 1995  to  $4.9
million  for  the three  month  period ended  March  31, 1996.  The  increase in
interest expense reflects additional  interest on the Series  D Notes that  were
issued  principally to finance the acquisitions  of CRS, Mascot and King-O-Matic
and the related amortization of debt issuance costs.
 
    CONSOLIDATED YEAR ENDED DECEMBER 31, 1995 COMPARED TO PRO FORMA YEAR ENDED
DECEMBER 31, 1994
 
    NET SALES.  Net sales increased by $32.9 million from $157.8 million in 1994
to $190.7 in 1995 primarily as a result of the acquisitions of CRS, Mascot,  and
King-O-Matic.  The three new  acquisitions provided $24.7  million in additional
revenues. Net sales of remanufactured transmissions increased from $68.4 million
in 1994  to  $85.9  million  in 1995.  The  volume  increase  of  remanufactured
transmissions  resulted  principally from  the acquisitions  of CRS  and Mascot,
partially offset by a reduction in net sales of remanufactured transmissions  to
Chrysler  from $66.8  million in  1994 to  $64.8 million  in 1995.  Net sales to
Chrysler reflected a  decrease from $19.8  million during the  third quarter  of
1994    to    $13.2   million    for   the    third    quarter   of    1995   as
 
                                       20
<PAGE>
Chrysler reduced its inventory of remanufactured transmissions, partially offset
by an increase from  $16.4 million during  the fourth quarter  of 1994 to  $18.9
million for the fourth quarter of 1995. Net sales of repair kits, hard parts and
other  drive train products increased $6.0 million from $69.0 million in 1994 to
$75.0 million in  1995 primarily  as a result  of the  Company's acquisition  of
King-O-Matic.  Net sales of  remanufactured engines increased  $4.6 million from
$15.2 million  in  1994  to  $19.8  million in  1995.  The  volume  increase  of
remanufactured  engines resulted from increased demand  from Western Auto at its
retail outlets, and the addition of new retail customers.
 
    GROSS PROFIT.   Gross profit  as a percentage  of net  sales decreased  from
41.1%  in 1994 to 39.4% in 1995. The  gross profit decrease of 1.7% of net sales
was due  in large  part  to increased  labor  costs relating  to  remanufactured
engines  and  transmissions. The  Company was  not  able to  recover all  of the
additional costs through increased selling prices.
 
    In addition, the  aggregate gross  profit was affected  by the  acquisitions
that  occurred in 1995. Total net sales  in 1995 includes $24.7 million for CRS,
Mascot and King-O-Matic at a combined gross profit which was somewhat lower than
that of the Company as a whole for 1995.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  SG&A expenses increased  from
$30.4  million in 1994 to $39.0  in 1995 or, as a  percentage of net sales, from
19.2% in 1994 to  20.5% in 1995.  The increase was partly  due to the  Company's
acquisitions  of CRS, Mascot  and King-O-Matic, which  comprised $3.3 million of
the Company's SG&A expenses in 1995. Other significant factors that  contributed
to  the increase in SG&A  expenses were the relocation  of RPM's main facilities
from Azusa, California to Rancho Cucamonga, California and the addition of a new
manufacturing plant in Joplin, Missouri, both  of which resulted in an  increase
in ongoing SG&A expenses and a significant amount of non-recurring SG&A expenses
being  incurred during 1995. Legal, audit,  tax and other professional fees were
also higher in 1995 principally due to a full year of ATC operations as compared
with only five months of operations in 1994.
 
    AMORTIZATION OF  INTANGIBLE  ASSETS.    Amortization  of  intangible  assets
increased $0.3 million in 1995 reflecting the increase in intangible assets that
occurred as a result of the acquisitions of CRS, Mascot and King-O-Matic.
 
    INCOME  FROM OPERATIONS.   Principally as a result  of the factors described
above, income from  operations increased  from $31.5  million in  1994 to  $32.9
million in 1995.
 
    INTEREST  EXPENSE (INCOME),  NET.   Interest expense  increased $2.4 million
from $14.5 million in 1994  to $16.9 million in  1995. The increase in  interest
expense  reflects additional  interest on  the Series  D Notes  that were issued
principally to finance the acquisitions of CRS, Mascot and King-O-Matic and  the
related amortization of debt issuance costs.
 
    PRO FORMA 1994 COMPARED TO COMBINED 1993
 
    NET SALES.  Net sales increased by $47.1 million from $110.7 million in 1993
to  $157.8 million in 1994  primarily as a result of  increases in the number of
units sold. The increase in net sales  is primarily comprised of an increase  in
net  sales of  remanufactured transmissions  from $37.5  million during  1993 to
$68.4 million during 1994. The  volume increase of remanufactured  transmissions
resulted principally from increased demand from Chrysler due to an increased use
of  remanufactured  transmissions  in  lieu  of  rebuilt  transmissions  for OEM
warranty-related service. Net sales of repair  kits, hard parts and other  drive
train  products  increased $9.7  million  from $59.3  million  in 1993  to $69.0
million in 1994, despite  facility relocation of  five distribution centers  and
the  relocation of the  Company's Dayton, Ohio torque  converter plant to expand
capacity. Net sales of remanufactured engines increased $4.8 million from  $10.4
million  in 1993 to $15.2 million in 1994. The volume increase of remanufactured
engines resulted from increased demand from Western Auto at its retail outlets.
 
    GROSS PROFIT.   Gross profit  as a percentage  of net  sales increased  from
39.7%  in 1993 to 41.1% in  1994, primarily as a result  of an increase in gross
profit due to higher sales volume  resulting in greater absorption of  overhead.
During  1994,  the Company  began  its program  of  increasing capacity  and has
realized increased labor efficiencies with  the upgrading and reorganization  of
certain manufacturing facilities.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a percentage of net sales,
SG&A expenses decreased from 23.2% of net sales in 1993 to 19.2% of net sales in
1994, primarily due to higher sales volume. The
 
                                       21
<PAGE>
improvement  in the percentage occurred despite the additional expenses incurred
by the Company related to the start-up of the new Dayton torque converter plant,
increases in legal, accounting and professional fees relating to the integration
of the Predecessor Companies and  increases in administrative support  expenses.
Management  believes that approximately half of these expenses are non-recurring
in nature. SG&A expenses for purposes of the pro forma financial statements  for
1994  exclude $3.5  million of  one time  employee bonuses  and $0.8  million of
excess  executive  compensation  and  other  costs,  which  were  paid  by   the
Predecessor Companies, net of certain new overhead expenses.
 
    INCOME  FROM OPERATIONS.   Principally as a result  of the factors described
above, income from  operations increased  from $18.3  million in  1993 to  $31.5
million in 1994.
 
    INTEREST  EXPENSE (INCOME), NET.   Interest expense  increased $14.8 million
from $(.3) million in 1993  to $14.5 million in  1994. The increase in  interest
expense  reflects  interest  on  the  Series B  Senior  Notes,  interest  on the
outstanding amounts from time to time under the Revolving Credit Agreement,  and
the amortization of deferred debt issuance costs.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Since  the  Company's inception  in July  1994, the  Company has  funded its
operations and investments  in property and  equipment, including  acquisitions,
through  the issuance  of Senior Notes  totaling $162.4 million  and the private
sale of  Preferred and  Common Stock  totaling  $40 million,  and, to  a  lesser
extent, through cash provided by operating activities.
 
    Net  cash provided  by operating activities  was $10.8 million  in 1995. Net
cash used in operating  activities was $0.7 million  for the three months  ended
March  31, 1996 principally due  to the semi-annual cash  payment of interest on
the Senior Notes and increases in  working capital that exceeded the net  income
and depreciation for the period. Net cash used in investing activities was $45.4
million and $1.1 million for 1995 and for the three months ended March 31, 1996,
respectively. The net cash used in investing activities in 1995 was attributable
to  capital expenditures  of $5.2 million,  due primarily to  investments in the
Company's  Joplin,  Missouri  and  Rancho  Cucamonga,  California  manufacturing
facilities  and $40.3 million used to  acquire CRS, Mascot and King-O-Matic. Net
cash provided by financing activities was $34.0 million in 1995, due principally
to the issuance of $42.4 million of Senior Notes, which was partially offset  by
certain   payments  on  other   debt  facilities  and   amounts  due  to  former
stockholders. Net cash provided by financing activities was $0.9 million  during
the three months ended March 31, 1996 due to additional borrowings.
 
    The  Company has budgeted  $9.8 million for capital  expenditures for all of
1996. The budget  includes $2.1  million for  additional engine  remanufacturing
equipment and $3.1 million for transmission remanufacturing equipment to provide
additional  capacity. Of the budgeted capital  expenditures, as of May 31, 1996,
the Company had  incurred $2.8 million  and had placed  purchase orders of  $2.1
million for additional equipment and leasehold improvements.
 
    The  Company has a  $30.0 million revolving credit  facility that matures in
July 1999.  As of  March 31,  1996, the  Company had  approximately $26  million
available under the revolving credit facility.
 
    The  Company  believes that  cash  on hand,  cash  flow from  operations and
existing borrowing capacity will be  sufficient to fund its ongoing  operations.
To  the  extent  the  Company  is  successful  in  completing  acquisitions, the
Company's liquidity may be negatively affected, and the Company may be  required
to raise additional capital through additional borrowings or equity financing.
 
INFLATION; LACK OF SEASONALITY
 
    Although  the  Company is  subject to  the effects  of changing  prices, the
impact of inflation has not been  a significant factor in results of  operations
for  the periods presented. In some circumstances, market conditions or customer
expectations may prevent the Company from increasing the prices of its  products
to  offset the inflationary pressures that may increase its costs in the future.
Historically, there  has  been  little seasonal  fluctuation  in  the  Company's
business.

                                    BUSINESS
 
GENERAL
 
    The Company  is a  leading  remanufacturer and  distributor of  drive  train
products  used in the aftermarket repair of passenger cars and light trucks. The
Company's  principal  products  include  remanufactured  transmissions,   torque
converters  and engines, as well as remanufactured  and new parts for the repair
of automotive  drive  train  and  engine  assemblies.  The  Company's  principal
customers include: (i) independent transmission rebuilders, general repair shops
and  distributors (I.E.,  the Independent  Aftermarket); (ii)  OEMs, principally
Chrysler, for  use as  replacement  parts by  their  dealers; and  (iii)  retail
automotive  parts stores. The Company believes  it is uniquely positioned within
the highly fragmented aftermarket  for drive train products  as a result of  its
extensive  product line,  diverse customer  base and  broad geographic presence,
with 43 distribution centers throughout the United States and Canada.
 
    The Company  was  organized  in  1994  by  Aurora  Capital  Partners  and  a
management  team  led by  William A.  Smith  to combine  the businesses  of four
existing companies serving  the drive train  remanufacturing market. Since  that
time  the  Company  has  grown  both  internally  and  through  four  additional
acquisitions completed during  1995 and  1996. The Company  and its  predecessor
companies  have achieved  compound annual growth  in revenue of  37.5% from 1992
through March 31, 1996  (29.9% if the Company's  1995 and 1996 acquisitions  are
excluded).  The Company believes the key elements of its success are the quality
and breadth  of its  product  offerings and  the  Company's emphasis  on  strong
customer  relationships, promoted  by strong  technical support,  rapid delivery
time, innovative product development and  competitive pricing. In addition,  the
Company  has benefited from the  increasing use of remanufactured transmissions,
engines and other parts for aftermarket repairs as the industry recognizes  that
remanufacturing  provides a higher quality, lower cost alternative to rebuilding
the assembly or replacing it with a new assembly manufactured by an OEM.
 
    The Company's  strategy is  to achieve  growth both  internally and  through
strategic  acquisitions. The Company intends to expand its existing business by:
(i) increasing penetration of its current  customer base; (ii) gaining new  OEM,
Independent Aftermarket and retail customers; and (iii) introducing new products
to  both existing  and new customers.  Strategic acquisitions have  also been an
important  element  in  the  Company's  historical  growth.  The  Company   sees
significant  opportunities to  continue expanding its  customer base, geographic
presence  and  product  offerings  through  additional  strategic  acquisitions,
particularly   among  companies   serving  the   highly  fragmented  Independent
Aftermarket. Management  believes that  future acquisitions  will enable  it  to
enhance  the  Company's revenues  and profitability  by expanding  the Company's
existing distribution base, increasing  the range of  products sold through  the
Company's  distribution  network  and  realizing  economies  of  scale  in areas
including purchasing, administration and inventory management.
 
AUTOMOTIVE AFTERMARKET INDUSTRY
 
    MARKET SIZE AND GROWTH
 
    The automotive  aftermarket in  North America,  which consists  of sales  of
parts  and  services  for  vehicles  after  their  original  purchase,  has been
noncyclical and has generally experienced steady growth over the past ten years,
unlike the  market for  new  vehicle sales.  Between  1985 and  1995,  estimated
industry-wide   revenue   for   the   automobile   aftermarket   increased  from
approximately $126  billion  to $170  billion.  This consistent  growth  is  due
principally  to the increase in the number  of vehicles in operation that are in
the prime repair age of four to 12 years and the increase in the average  number
of  miles driven annually per vehicle.  The Company competes specifically in the
aftermarket segment for automotive transmissions, engines and other drive  train
related products, which represents more than $7 billion of the entire automotive
aftermarket.  The  Company  believes that  within  this segment  the  market for
remanufactured drive train products has grown faster than the overall automotive
aftermarket.

    REMANUFACTURING
 
    Remanufacturing  is  a  process  through  which  used  assemblies,  such  as
transmissions  or engines,  are returned  to a  central facility  where they are
disassembled and  their  component parts  cleaned,  refinished and  tested.  The
usable  component  parts are  then combined  with  new parts  in a  high volume,
precision manufacturing process to create remanufactured assemblies.
 
    When a drive train  assembly such as a  transmission or engine fails,  there
are  generally three alternatives  available to return  the vehicle to operating
condition. The dealer or independent repair  shop may: (i) remove the  assembly,
disassemble  the unit  into its component  pieces, replace worn  or broken parts
with remanufactured or new components, and reinstall that assembly  ("rebuild");
(ii)  replace the assembly  with a remanufactured assembly  or; (iii) in limited
instances, replace the  assembly with a  new assembly manufactured  by the  OEM.
Costs  to the  OEM associated with  remanufactured assemblies  generally are 50%
less than new  or rebuilt  assemblies due to  the remanufacturers'  use of  high
volume  manufacturing techniques and salvage methods that increase the number of
reusable components.  In addition,  remanufactured assemblies  are generally  of
higher  quality than rebuilt  assemblies because of  the precision manufacturing
techniques, technical upgrades  and rigorous inspection  and testing  procedures
employed  in remanufacturing. In contrast, the  quality of a rebuilt assembly is
heavily dependent on the skill level  of the particular mechanic, who  typically
is  less able to  remain current with  engineering changes than remanufacturers,
who work in close liaison with OEM engineers. In addition, the proliferation  of
transmission  and engine designs, the increasing complexity of transmissions and
engines that  incorporate  electronic components,  and  the shortage  of  highly
trained  mechanics  qualified to  rebuild assemblies  all  have tended  to favor
remanufacturing over rebuilding assemblies for aftermarket repairs. For warranty
repairs, consistent quality of warranty repairs is important to the OEM standing
behind the  applicable  warranty,  because once  installed,  the  remanufactured
product  is usually covered by the OEM  for the balance of the original warranty
period. The Company believes  that because of this  combination of high  quality
and  low cost, the  use of remanufactured assemblies  for aftermarket repairs is
growing compared to the use of new or rebuilt assemblies.
 
PRODUCTS
 
    The principal product lines of the Company are remanufactured transmissions,
repair kits  and hard  parts used  in drive  train repairs,  and  remanufactured
engines. The following table sets forth, by product line, the Company's combined
net  sales (dollars in millions)  and the percentage of  the Company's total net
sales for the years 1993, 1994 and 1995  and the first three months of 1995  and
1996:

    TRANSMISSIONS
 
    The  Company  remanufactures transmissions  which  are factory  approved and
suitable  for  warranty  and  post-warranty  replacement  of  transmissions  for
Chrysler and 12 foreign OEMs, including Hyundai Motor America, Subaru of America
and  American  Isuzu, for  their United  States dealer  networks. The  number of
transmission models  remanufactured  by  the  Company  has  been  increasing  to
accommodate the greater number of models currently used in vehicles manufactured
by  the Company's OEM customers. The majority of the Company's transmissions are
sold to Chrysler  under Chrysler's MOPAR  brand name. In  addition, the  Company
rebuilds heavy duty truck transmissions and air compressors in Canada.
 
    REPAIR KITS AND HARD PARTS
 
    Repair  kits sold by the Company consist of gaskets, friction plates, seals,
bands, filters and other "soft" parts that are used in rebuilding  transmissions
for  substantially  all  domestic and  most  imported passenger  cars  and light
trucks. Kits are currently sold principally to the Independent Aftermarket. Each
kit is designed
 
                                       24
<PAGE>
specifically to  include  substantially all  of  the soft  parts  necessary  for
rebuilding  a particular model of transmission.  In addition to manufacturing or
remanufacturing certain of the components that are used in its kits, the Company
maintains a variety of supply relationships that allow it to purchase components
for  its   kits  at   competitive  prices.   The  components   manufactured   or
remanufactured  by  the Company  include  various friction  plates,  gaskets and
bands. Many  of  the  Company's  competitors  do  not  manufacture  any  of  the
components that they distribute and the Company believes this provides it a cost
advantage  over its competitors.  The repair kits  are sold under  the RPM, HTP,
KING-O-MATIC and TRANZPARTS brand names.
 
    The Company  remanufactures  torque  converters  (the  coupler  between  the
transmission  and engine), planetary gears  (speed regulating devices inside the
transmission)  and  transmission  fluid  pumps.  These  "hard"  parts  are  sold
principally  to the Independent Aftermarket for use in drive train repairs. Many
of the Company's competitors do not distribute as broad a line of hard parts  or
remanufacture  hard  parts  that  they distribute.  The  Company  believes these
factors provide it both an availability and cost advantage over its competitors.
Hard parts are sold under the RPM, HTP, MAMCO AND TRANZPARTS brand names.
 
    ENGINES
 
    The Company remanufactures engines designed  as replacement engines for  use
in  many  domestic  passenger cars  and  light trucks.  Principal  customers are
Western Auto, O'Reilly Auto  Parts and APS Holding  Corporation, as well as  the
Independent Aftermarket. Over the past three years, the variety of engine models
remanufactured  by the Company  has increased from  50 to 75  as the Company has
expanded the range  of engines offered  to meet customer  requirements. In  June
1996,  the Company  introduced engine  repair kits  marketed to  the Independent
Aftermarket under the PROFORMANCE brand name. These kits are designed to provide
mechanics with the components required to repair or rebuild a broad selection of
domestic engine models.
 
    OTHER
 
    Other  products  consist  principally  of  remanufactured  rack  and  pinion
assemblies  and CV axles for passenger cars and light trucks for the Independent
Aftermarket, and cleaning and testing equipment for the Independent  Aftermarket
and  other industrial  businesses. These products  are sold under  the RPM, HTP,
KING-O-MATIC, TRANZPARTS and  INTERCONT brand  names. In the  fourth quarter  of
1995,  the Company became  the sole supplier of  fully enclosed aqueous cleaning
equipment to Safety-Kleen (a provider of parts cleaner services). This equipment
permits the cleaning of automotive and industrial components without the use  of
environmentally damaging solvents.
 
MARKETING AND DISTRIBUTION
 
    The  Company distributes its  products to: (i)  the Independent Aftermarket;
(ii) its OEM customers for use as replacement parts by their dealers; and  (iii)
retail automotive parts stores.
 
    INDEPENDENT AFTERMARKET
 
    The  Company supplies transmission repair kits  and hard parts used in drive
train  repairs  to   over  11,000  of   the  approximately  17,000   independent
transmission  rebuilders and distributors in the  United States and Canada, such
as AAMCO Transmissions Inc.,  MOTRA Corp. and Lee  Myles Associates Corp.  These
products  are used in  the Independent Aftermarket  to rebuild transmissions and
other assemblies using remanufactured and  new component parts purchased from  a
variety  of suppliers. In addition, the Company supplies transmission and engine
repair kits, hard parts used in drive train repairs, remanufactured engines  and
certain  remanufactured  components  such  as  CV axles  to  over  1,000  of the
approximately 54,000 general repair shops in the United States. Transmission and
engine repairs  performed  in  the Independent  Aftermarket  are  generally  for
vehicles no longer covered by warranty or for OEM dealers who do not have access
to  remanufactured  assemblies  or  lack  the  in-house  capabilities  to repair
transmissions.
 
    There are two characteristics of the Independent Aftermarket that  influence
the  Company's business  strategy. First,  as the  number of  vehicle models has
proliferated and  repairs  have  become increasingly  complex,  the  Independent
Aftermarket  has grown more dependent on its suppliers for technical support and
for assistance in  managing inventory  by delivering product  on a  just-in-time
basis   at  competitive   prices.  Second,   Independent  Aftermarket  customers
(including   those    affiliated    with   larger    organizations    such    as
 
                                       25
<PAGE>
AAMCO,  MOTRA and Lee  Myles) generally purchase parts  at the individual repair
shop level. Independent Aftermarket customers tend to make purchasing  decisions
based  on  availability and  rapid  delivery of  products,  competitive pricing,
breadth of  product  offering and  technical  assistance. To  respond  to  these
requirements,  the Company has  developed a strategy  of geographic expansion of
its distribution system  to provide its  Independent Aftermarket customers  with
short-notice  rapid delivery,  high service levels  and technical  support for a
broad product offering  in each local  market. This is  accomplished through  43
distribution  centers located throughout the United States and Canada from which
the Company  provides local  technical  support and  a  wide range  of  products
delivered by Company-operated trucks to its customers. The Company believes that
this  system is the most extensive in  the drive train segment of the automotive
aftermarket and represents a competitive  advantage for the Company relative  to
its  typically  smaller, local  competitors.  Accordingly, the  Company believes
there are opportunities  for further geographic  penetration in this  relatively
fragmented  market. See "-- Business Strategy  -- Internal Growth -- Independent
Aftermarket."
 
    The Company  has developed  a common  product identification  and  numbering
system  which  is  currently  being  implemented  on  a  Company-wide  basis. In
addition,  the  Company  is  in  the  process  of  electronically  linking   its
distribution  centers through a computer network that will enable each center to
determine more quickly  if and  where a particular  part is  located within  the
distribution  system, thereby  further enhancing  customer service.  The Company
expects to  implement  this process  in  stages during  1996  and 1997,  and  it
estimates  that the process will be completed  by the end of 1997. These changes
are expected to improve customer service, increase product availability, enhance
inventory management and improve operational efficiencies.
 
    New customers  are developed  by a  direct sales  force operating  from  the
Company's  local distribution centers,  by national and  local trade publication
advertising and by telemarketing. The Company also participates in trade  shows.
The Company believes its RPM, HTP, KING-O-MATIC, MAMCO, TRANZPARTS and INTERCONT
brand  names are well recognized and  respected in their regional markets. Sales
to Independent  Aftermarket  customers  accounted for  44.9%  of  the  Company's
revenues in 1995 and 39.2% in the first quarter of 1996.
 
    OEM CUSTOMERS
 
    The  Company provides factory-approved  remanufactured transmissions to OEMs
for use in warranty and, to a lesser extent, post-warranty repair work by  their
dealers.  The Company's  largest OEM customer  is Chrysler, to  whom the Company
also supplies certain factory-approved remanufactured engines. The Company sells
to 12  foreign OEMs,  including Hyundai  Motor America,  Subaru of  America  and
American  Isuzu. Products are  sold to each OEM  pursuant to supply arrangements
for individual  transmission  models.  Sales  to  the  Company's  OEM  customers
accounted  for 44.9% of the  Company's 1995 revenues and  49.1% of first quarter
1996 revenues. Sales to Chrysler accounted for 35.4% and 36.9% of the  Company's
revenues  in 1995  and in  the first  quarter of  1996, respectively.  See "Risk
Factors -- Dependence on Significant Customer."
 
    Over the past  12 years,  the Company  has developed  and maintained  strong
relationships at many levels of both the corporate and the factory organizations
of  Chrysler. In recognition of the Company's consistently high level of service
and product  quality throughout  its  relationship with  Chrysler, in  1995  the
Company  was awarded  the Platinum Pentastar  award, the  highest award Chrysler
bestows on  a supplier.  The Company's  Platinum Pentastar  was one  of only  14
awarded  to Chrysler's 3,500 suppliers in 1995 and marks the first time that the
Platinum Pentastar has been  awarded to a remanufacturer  or to a supplier  that
serves  exclusively as  a MOPAR aftermarket  parts supplier. In  addition to its
Platinum Pentastar, the Company received Gold Pentastar awards in 1993, 1994 and
1995. Only seven suppliers  received the Gold Pentastar  award in each of  these
years.
 
    Chrysler  began implementing  remanufacturing programs  for its transmission
models in 1986 and selected the  Company as its sole supplier of  remanufactured
transmissions  in 1989. Chrysler has advised the Company that, by implementing a
remanufacturing  program,  Chrysler  has  realized  substantial  warranty   cost
savings,  standardized  the  quality  of its  dealers'  aftermarket  repairs and
reduced its own inventory of
 
                                       26
<PAGE>
replacement  parts.  Currently,  Chrysler   has  remanufacturing  programs   for
transmission  models that  are used in  less than  70% of its  vehicles, and the
Company is the  only factory-approved supplier  of remanufactured  transmissions
for  these models. The Company estimates that, of the Chrysler transmissions for
which there is a  remanufacturing program, the  Company currently provides  less
than  50% of the transmissions subject to major repair by Chrysler dealers, with
the balance being rebuilt by the dealers. This has been due to dealers' electing
to rebuild  transmissions,  generally  through their  own  service  departments,
rather than replacing them with remanufactured assemblies, as well as historical
constraints  on the availability to  the Company of parts  from Chrysler used in
the remanufacturing process and, to a  lesser extent, the availability of  cores
to the Company.
 
    As  part of its expanding relationship with  Chrysler and in response to the
periodic  shortage  of  cores,  at  Chrysler's  request  the  Company   recently
established  a central  core return  center for  all of  Chrysler's transmission
models and certain engine lines through  which the Company manages the  tracking
and  return of  cores. Under the  Company's management  system, Chrysler dealers
make arrangements to  ship transmission and  engine cores to  a regional  depot,
which  then ships directly  to the Company's central  core return center located
near its main  remanufacturing facility.  The Company thus  assists Chrysler  by
improving  the  efficient  and timely  return  of  cores at  a  cost  savings to
Chrysler. Furthermore, the  Company performs value-added  services such as  core
audit  and analysis  in conjunction  with Chrysler  engineers. Additionally, the
Company's improved  ability to  track  core supply  allows  it to  schedule  its
production  more  efficiently.  The  Company  believes  that  this  central core
facility has reduced the  risk of future Chrysler  core shortages. In  addition,
the  increased number  of cores  has resulted  in a  greater number  of reusable
parts, which, together with recently  expanded production capacity at  Chrysler,
has  increased the  Company's supply  of parts  required in  the remanufacturing
process.
 
    Net sales to Chrysler grew  from $14.9 million in  1991 to $67.6 million  in
1995  and were  $23.7 million  for the  first quarter  of 1996.  The Company has
developed a  new production  line dedicated  to remanufacturing  certain of  the
Chrysler  transmission models  that are not  yet covered  by the remanufacturing
programs and has received an initial purchase order from Chrysler, although  the
Company has not begun remanufacturing these transmission models.
 
    RETAIL AUTOMOTIVE PARTS STORES
 
    The  Company  supplies  remanufactured  engines,  transmission  filter kits,
engine components  and engine  repair kits  to a  portion of  the  approximately
60,000  automotive aftermarket retail stores throughout the United States, which
offer new and remanufactured parts and assemblies to a broad range of customers,
principally "do-it-yourself"  customers and  general  repair shops.  The  retail
automotive  parts  store market  is highly  fragmented  with most  retail stores
obtaining products similar to  those provided by the  Company from a variety  of
regional  suppliers. These customers tend to  make purchasing decisions based on
price, rapid delivery of products and breadth of product offering. As a supplier
with a national scope and a broader  product line than many of its  competitors,
the  Company provides high quality products, competitive prices and high service
levels as  well  as promotional  literature  and advertisements.  The  Company's
principal  retail customers are Western Auto (885 retail locations in 35 states)
and O'Reilly Auto Parts (191 retail  locations in five states). Sales to  retail
automotive  parts stores have grown from virtually zero in 1991 to $19.8 million
in 1995 and $7.5 million in the first quarter of 1996.
 
BUSINESS STRATEGY
 
    The Company's  strategy is  to achieve  growth both  internally and  through
strategic  acquisitions. The Company intends to expand its existing business by:
(i) increasing penetration of its current  customer base; (ii) gaining new  OEM,
Independent Aftermarket and retail customers; and (iii) introducing new products
to  both existing  and new customers.  Strategic acquisitions have  also been an
important  element  in  the  Company's  historical  growth.  The  Company   sees
significant  opportunities to  continue expanding its  customer base, geographic
presence  and  product  offerings  through  additional  strategic  acquisitions,
particularly   among  companies   serving  the   highly  fragmented  Independent
Aftermarket. Management  believes that  future acquisitions  will enable  it  to
improve   the   Company's   revenues   and   profitability   by   expanding  the
 
                                       27
<PAGE>
Company's existing  distribution base,  increasing the  range of  products  sold
through  the Company's distribution network and  realizing economies of scale in
areas including purchasing, administration and inventory management.
 
    INTERNAL GROWTH -- INDEPENDENT AFTERMARKET
 
    INCREASING BUSINESS TO  EXISTING CUSTOMERS.   The Company  believes that  it
currently  supplies less than one-third of the remanufactured or new drive train
component requirements  of its  Independent Aftermarket  customers. The  Company
believes  it is well positioned  to expand sales to  these customers through the
implementation of a common parts  numbering system, a systemwide  computer-based
inventory tracking system and the stocking in a central location of certain hard
parts that the Company's customers have previously had difficulty obtaining. The
Company  also  intends  to  expand  its  business  with  existing  customers  by
cross-selling  products  among   its  subsidiaries'   customers.  For   example,
King-O-Matic  has recently introduced  Mamco torque converters  to its customers
and RPM has increased its hard parts sales by offering HTP products.
 
    ESTABLISHING NEW  CUSTOMER RELATIONSHIPS.   The  Company believes  that  its
product  mix  and distribution  network position  it  to expand  its Independent
Aftermarket  customer  base   in  two  ways.   First,  although  the   Company's
distribution  network is currently the most extensive in the drive train segment
of the  automotive  aftermarket, there  are  significant opportunities  for  the
Company  to expand to  additional geographic markets.  The Company currently has
facilities in 41  markets in  the United States  and Canada  and has  identified
expansion  opportunities in over  60 additional markets.  The Company opened ten
and closed two distribution  centers in 1995. Second,  the Company recently  has
expanded its customer base to include general repair shops in the United States.
Although  the Company  began supplying  this market on  a selected  basis with a
limited product line in  1993, since January 1995  the Company has expanded  its
distribution  of remanufactured engines  and engine repair kits  from two to ten
distribution centers and plans to expand the availability of these product lines
to its other distribution centers. The Company now serves approximately 1,000 of
the approximately  54,000  general  repair  shops  in  the  United  States.  The
Company's  product line breadth and depth  and its distribution network contrast
with those of many other suppliers which offer only a limited product line on  a
regional  or local level.  These factors are  expected to enable  the Company to
broaden its  penetration  among general  repair  shops with  minimal  additional
investment.
 
    INTRODUCING NEW PRODUCTS.  The Company regularly introduces new products for
the  Independent  Aftermarket.  The  Company monitors  sales  trends  and  is in
frequent communication  with customers  regarding  potential new  products.  For
example,  the Company has increased its  remanufactured engine models from 50 to
75 since the  beginning of 1995.  The Company believes  that its reputation  for
high   quality  products  and  customer  service  enables  it  to  leverage  its
relationships with existing customers to sell additional products.
 
    The Company also  explores other  opportunities to  service the  Independent
Aftermarket.  For example,  the Company  has become  the sole  supplier of fully
enclosed aqueous cleaning equipment to Safety-Kleen, a provider of parts cleaner
services. The Company expects  that the market  for aqueous cleaning  equipment,
which  allows automotive and industrial  parts to be cleaned  without the use of
environmentally damaging  solvents,  will  grow due  to  increasingly  stringent
environmental regulations regarding the use and disposal of solvents.
 
    INTERNAL GROWTH -- OEM
 
    INCREASING SALES TO EXISTING CUSTOMERS.  The Company intends to increase its
business  with its existing OEM  customers by working with  the OEMs to increase
dealer utilization  of remanufactured  transmissions in  both the  warranty  and
post-warranty period. The Company estimates that, of the transmissions for which
its  OEM customers have remanufacturing programs, the Company currently provides
less than 50% of  the transmissions subject to  major repair by such  customers,
with the balance being transmissions rebuilt by dealer mechanics. The Company is
working  in  tandem with  OEMs  to highlight  to  dealers the  quality  and cost
advantages of using  remanufactured assemblies versus  rebuilding. In  addition,
the  post-warranty repair  market, which  the Company  believes is approximately
eight times as large as the OEM dealer warranty
 
                                       28
<PAGE>
repair market, presents a  growth opportunity. Currently,  the vast majority  of
post-warranty  repairs are performed in  the Independent Aftermarket rather than
at  OEM  dealers.  Given  the  relatively   low  cost  and  higher  quality   of
remanufactured  components, OEM  dealers can enhance  their cost competitiveness
compared  to  independent   service  centers  through   the  increased  use   of
remanufactured  components  as well  as providing  end  customers with  a higher
quality product.  To  the  extent  that OEM  dealers  increase  their  level  of
post-warranty  repairs, the  Company is  well positioned  to capitalize  on this
market growth.
 
    INTRODUCING NEW PRODUCTS.   The Company has  introduced 33 new  transmission
models  and a number of related drive train products in the last three years for
its OEM customers. The Company has developed a new production line dedicated  to
remanufacturing  certain of  the Chrysler transmission  models that  are not yet
covered by  the remanufacturing  program and  has received  an initial  purchase
order,  although the Company  has not begun  remanufacturing these new products.
The Company's ability to add  new products is in  part dependent on the  support
and  approval of  the OEM.  The Company  believes that  its reputation  for high
quality products and customer service  will generate increased demand from  OEMs
for additional remanufactured components.
 
    ESTABLISHING   NEW  CUSTOMER  RELATIONSHIPS.    The  Company  believes  that
opportunities exist  with several  foreign automotive  OEMs relative  to  United
States based remanufacturing programs. The Company believes that this represents
an  opportunity for  growth and  is currently  working to  develop programs with
certain  foreign  OEMs.  In  1995,   the  Company  initiated  a   remanufactured
transmission  program  for  Mitsubishi  and  currently  supplies  remanufactured
transmissions models used in approximately 65% of the Mitsubishi vehicles.
 
    INTERNAL GROWTH -- RETAIL STORES
 
    INCREASING SALES TO EXISTING CUSTOMERS.  The Company intends to increase its
business with its existing  retail customers by  increasing the distribution  of
its  current products throughout these customers' networks. For example, in 1992
the Company began supplying remanufactured engines to Western Auto and in  1996,
was   selected  to  supply  remanufactured  engines  to  Western  Auto's  fourth
distribution center,  thereby expanding  this relationship  to include  all  885
Western  Auto stores. The Company has  generally increased its business with its
existing retail  customers as  they  have increased  their market  coverage  and
expects to continue to do so. In addition, the Company intends to increase sales
to  existing customers by providing  customized marketing programs. For example,
in 1995 the Company introduced  an extended warranty program for  remanufactured
engines to certain of its retail store customers.
 
    ESTABLISHING  NEW CUSTOMER RELATIONSHIPS.   Of the  60,000 retail automotive
parts stores  in the  United States,  the Company  currently sells  products  to
approximately 1,000 stores, principally through three retail chains. The Company
believes  that its  position as  a leading  national supplier  of remanufactured
engines affords it the opportunity to service additional national retail  chains
as certain of these chains convert from a currently fragmented base of suppliers
and  as  other  chains  expand their  product  lines  to  include remanufactured
engines. For example, in 1995 the Company added O'Reilly Auto Parts and in  1996
the  Company  added APS  Holding Corporation  (which conducts  retail operations
under names including "Big A Auto Parts") as customers.
 
    INTRODUCING NEW  PRODUCTS.   The  Company plans  to  increase its  sales  to
existing  retail  automotive  parts store  customers  by  introducing additional
products such  as  clutch  kits,  engine  components  and  engine  repair  kits.
Recently,  the Company's product offerings to  retail chain stores were enhanced
by the acquisition of King-O-Matic, which added transmission filter kits to  the
Company's  product line.  King-O-Matic products  have been  subsequently sold to
certain existing retail  customers, allowing  the Company  to increase  revenues
with limited incremental expenses.
 
    EXTERNAL GROWTH -- ACQUISITIONS
 
    Strategic  acquisitions  have been  an  important element  in  the Company's
historical growth,  and the  Company plans  to continue  expanding its  customer
base,  geographic locations and product offerings through strategic acquisitions
in the future. The  Independent Aftermarket supplier  base is highly  fragmented
and  many local independent drive train  product distributors lack the financial
and managerial resources  to expand.  Many such distributors  also have  limited
opportunities to realize their investment in the business.
 
                                       29
<PAGE>
This  dynamic  has  historically  created  a  significant  number  of attractive
potential acquisition  candidates  and  the Company  believes  that  significant
opportunities  for profitable growth through acquisitions will continue to exist
for the foreseeable future. By  integrating an acquired company's products  into
the  Company's distribution system, the Company  is able to offer these products
to a substantially  greater number of  markets than  was the case  prior to  the
acquisition.  In addition, the Company expects  to realize economies of scale in
areas including purchasing, administration and inventory management.
 
    The  Company's  management   is  experienced   in  identifying   acquisition
opportunities  and completing and integrating acquisitions within the automotive
aftermarket. Since its formation and acquisition of Aaron's, HTP, Mamco and  RPM
in 1994, ATC has acquired CRS, Mascot and King-O-Matic in 1995 and Tranzparts in
April 1996.
 
REMANUFACTURING OF TRANSMISSIONS, HARD PARTS AND ENGINES
 
    In  its remanufacturing operations, the  Company obtains used transmissions,
hard parts, engines and related components, commonly known as "cores," which are
sorted by make and model and  either placed into immediate production or  stored
until  needed.  In  the remanufacturing  process,  the cores  are  evaluated and
disassembled into their component parts. The components that can be incorporated
into  the  remanufactured  product  are  cleaned,  tested  and  refinished.  All
components   determined  not  reusable  or  repairable  are  replaced  by  other
remanufactured  or  new  components.  The  units  are  then  reassembled   using
high-volume   precision  manufacturing  techniques   into  finished  assemblies.
Inspection and testing are  conducted at various  stages of the  remanufacturing
process,  and each finished assembly is tested on equipment designed to simulate
performance under operating conditions.  Primarily as a  result of its  rigorous
quality  control procedures, the Company has experienced an insignificant number
of warranty claims on its products.  After testing, completed products are  then
packaged  for immediate delivery or shipped to one of the Company's distribution
centers.
 
    The majority of the cores used in the Company's remanufacturing process  for
sale  to  its Independent  Aftermarket and  retail  customers are  obtained from
customers as trade-ins. The Company  encourages its Independent Aftermarket  and
retail  customers to  return cores  on a  timely basis  and charges  customers a
supplemental core charge in  connection with purchases  of engines and  critical
hard  parts. The customer can satisfy this  charge by returning a usable core or
making a cash payment equal  to the amount of  the supplemental core charge.  If
cores  are not returned in a timely  manner, the Company then must procure cores
through its network of independent core  brokers. While core prices are  subject
to  supply and  demand price  volatility, the  Company believes  its procurement
network for cores will continue to provide cores at reasonable prices.
 
COMPETITION
 
    The Company competes  in the  highly fragmented  automobile aftermarket  for
transmissions,  engines and other drive train  components, in which the majority
of industry supply comes from small local/regional participants. Competition  is
based  primarily on  product quality,  service, delivery,  technical support and
price. Many  of the  Company's competitors  operate only  in certain  geographic
regions  with  a  limited  product  line. The  Company  is  one  of  the largest
participants in  the  aftermarket  for remanufactured  drive  train  components,
offers  a more complete line of products across a varied customer base and has a
much broader geographic presence than many of its competitors. As a result,  the
Company  believes that it is well positioned to enhance its competitive position
by expanding  its  product line  through  the  development of  new  products  or
acquisition  of new businesses as well  as by expanding its distribution network
into new geographic  markets. Nevertheless, the  aftermarket for  remanufactured
drive  train components remains highly competitive, and certain of the Company's
competitors are larger  than the Company  and have greater  financial and  other
resources available to them than does the Company.

ENVIRONMENTAL
 
    The Company is subject to various evolving federal, state, local and foreign
environmental laws and regulations governing,  among other things, emissions  to
air,  discharge to waters and the generation, handling, storage, transportation,
treatment and disposal of  a variety of  hazardous and non-hazardous  substances
and  wastes.  These  laws  and regulations  provide  for  substantial  fines and
criminal  sanctions   for  violations.   The  operation   of  automotive   parts
remanufacturing plants involves environmental risks.
 
    Prior  to the RPM Acquisition, the company from whom RPM acquired its assets
(the "Prior  RPM  Company")  leased  nine  properties  in  the  City  of  Azusa,
California (the "Azusa Properties") from a general partnership consisting of the
Prior  RPM Company shareholders. The Azusa  Properties are within an area which,
as a result of  regional groundwater contamination, has  been designated by  the
EPA  as  the Baldwin  Park  Operable Unit  ("BPOU")  of the  San  Gabriel Valley
Superfund Sites.  The federal  Superfund  law (the  Comprehensive  Environmental
Response,  Compensation, and Liability Act of  1980, as amended ("CERCLA")) both
provides for the appropriate cleanup of contaminated sites and assigns liability
for the cost of  such cleanups. The parties  held responsible for cleanup  costs
are  broadly  defined under  CERCLA, and  generally  include present  owners and
operators of a site and certain past owners and operators. Liability for cleanup
costs imposed against such "responsible  parties" is strict, joint and  several.
However,  such costs are  typically allocable among  responsible parties through
settlement or  litigation based  on factors  including each  particular  party's
relative contribution of contaminants to the site and ability to pay.
 
    The  EPA has proposed a groundwater  treatment system as an interim remedial
measure for the BPOU. The EPA has estimated that it will cost approximately  $47
million  to construct this system  and approximately $4 million  per year for an
indefinite period to  operate it.  The Company has  not independently  evaluated
this estimate, and the actual cost may vary substantially from this estimate. In
addition,  the  EPA  has incurred  substantial  costs  to date  and  will likely
continue to  incur  such costs  in  overseeing the  implementation  of  remedial
measures.  Further, if the EPA determines that the interim remedial measures are
not adequate, additional costs could be incurred. In addition to cleanup  costs,
the  responsible parties may be required to pay for natural resources damage. In
1993, the EPA notified the Prior RPM Company, the general partnership consisting
of the  Prior RPM  Company  shareholders which  owns  the Azusa  Properties  and
approximately  100  other  entities  that they  may  be  potentially responsible
parties ("PRPs") for the San Gabriel Valley Superfund Sites as present or former
owners or operators of properties located within that Site. In January 1995, the
EPA sent letters to  16 of these  parties with respect to  15 properties in  the
BPOU,  describing 4 of those properties  as apparently the "largest contributors
to the groundwater contamination" and the remaining 11 properties as  apparently
in  a  range  of  moderate  to lesser  contributors.  The  letters  identify the
recipients as PRPs for  the proposed interim remediation  and request that  they
enter into negotiations to design, construct and operate the cleanup remedy. The
recipients  of the letters included a general partnership comprised of the Prior
RPM  Company  shareholders,  which  was  informed  that  the  EPA  considers  it
responsible for two of the sites described as lesser to moderate contributors to
the contamination.
 
    In  conjunction with  the federal  and state  environmental investigation of
this area, the Prior  RPM Company has been  required by the California  Regional
Water  Quality Control Board (the "Water  Board") to conduct an investigation on
the Azusa  Properties. This  investigation has  detected soil  contamination  on
certain  of the  Azusa Properties formerly  leased by  RPM and as  a result, the
Prior RPM Company  is being  required by the  Water Board  to undertake  further
investigations  and  may  be  required to  undertake  remedial  action  on those
properties.
 
    For one  year  after the  RPM  Acquisition,  the Company  leased  the  Azusa
Properties pursuant to leases which provide that the Company has not assumed any
liabilities  with respect to environmental conditions existing on or about these
properties prior to the commencement of  the lease period, although the  Company
could  be held  responsible for such  liabilities under  various legal theories.
Since the RPM Acquisition, the Company has been engaged in negotiations with the
EPA to settle any liability that it may have for this site. The RPM  acquisition
agreement provides that the Company did not assume any environmental liabilities
associated  with hazardous substances existing on  or about the Azusa Properties
occupied by the Prior RPM
 
                                       32
<PAGE>
Company prior to  the RPM Acquisition  and that  the Prior RPM  Company and  the
Prior  RPM Company shareholders will jointly and severally indemnify the Company
for all  liabilities or  damages  (other than  consequential damages)  that  the
Company  may reasonably  incur as  a result  of any  claim asserted  against the
Company relating  to  unassumed  environmental  liabilities.  There  can  be  no
assurance,  however, that the Company  would be able to  make any recovery under
any indemnification provisions. The Company also could become responsible if the
conduct of its business contributed to any environmental contamination on  these
properties.  The  Company  took  steps  to insure  that  its  business  at these
properties was conducted in compliance with applicable environmental laws and in
a manner that does not contribute to any environmental contamination.  Moreover,
the Company has significantly reduced its presence at the site and has moved all
manufacturing  operations off-site. Since July 18, 1995, the Company's only real
property interest in the Azusa Properties has  been the lease of a 6,000  square
foot storage and distribution facility. The Company believes, although there can
be  no assurance, that it  will not incur any material  liability as a result of
the pre-existing environmental conditions.
 
    In connection with the CRS,  Mascot, King-O-Matic, Aaron's, RPM, HTP,  Mamco
and  Tranzparts acquisitions,  the Company  conducted certain  investigations of
these companies' facilities and  their compliance with applicable  environmental
laws.  The investigations, which  included "Phase I"  assessments by independent
consultants of all manufacturing and certain distribution facilities, found that
certain remedial, reporting and other regulatory requirements, including certain
waste management procedures, were not or  may not have been satisfied. Based  in
part  on the investigations conducted, and the indemnification provisions of the
agreements entered  into  in connection  with  these acquisitions,  the  Company
believes,  although there can be no  assurance, that its liabilities relating to
these  environmental  matters   will  not  have   a  material  adverse   effect,
individually or in the aggregate, on the Company.
 
LEGAL PROCEEDINGS
 
    From  time to time,  the Company has  been and is  involved in various legal
proceedings. Management  believes that  all  of such  litigation is  routine  in
nature  and incidental  to the conduct  of its  business, and that  none of such
litigation, if  determined  adversely to  the  Company, would  have  a  material
adverse effect, individually or in the aggregate, on the Company.
 
EMPLOYEES
 
    As  of March 31, 1996, the  Company employed approximately 2,800 people. The
Company believes  its  employee  and  labor relations  are  good.  None  of  the
Company's  subsidiaries has experienced a work  stoppage in its history, and the
Company has not experienced any work stoppage since its formation in 1994.  None
of the Company's employees are members of any labor union.

Company's  Common Stock. In February 1995,  the Stock Incentive Plan was amended

Incentive  Plan is administered  by the Compensation  Committee, which has broad
authority in administering and interpreting the Stock Incentive Plan. Awards are
not restricted  to any  specified form  or structure  and may  include,  without
limitation,  sales or bonuses of stock,  restricted stock, stock options, reload
stock  options,  stock  purchase  warrants,  other  rights  to  acquire   stock,
securities  convertible into or redeemable for stock, stock appreciation rights,
phantom stock,  dividend equivalents,  performance units  or performance  shares
(collectively, "Awards"). Options granted to employees under the Stock Incentive
Plan may be options intended to qualify as incentive stock options under Section
422 of the Internal Revenue Code of

1986,  as amended, or options not intended to so qualify. An Award granted under
the Stock Incentive Plan to an employee or independent contractor may include  a
provision  terminating the  Award upon  termination of  employment under certain
circumstances or accelerating  the receipt  of benefits upon  the occurrence  of
specified  events, including, at  the discretion of  the Compensation Committee,
any change of control of the Company.
 
    As of  June  15,  1996, the  Company  has  granted options  to  purchase  an
aggregate  of up to 254,463 shares of  Common Stock to officers and employees of
the Company. The exercise price for these options is $10 per share. Each  option
is  subject  to certain  vesting  provisions. All  options  expire on  the tenth
anniversary of  the date  of grant.  For certain  information regarding  options
granted to officers of the Company, see "Ownership of Voting Securities."

                              CERTAIN TRANSACTIONS
 
    The Company believes the transactions described below that were entered into
by the Company and its subsidiaries were beneficial to the respective companies,
and  were at least as  favorable to the respective  companies as could have been
obtained from unaffiliated third parties pursuant to arms-length negotiations.
 
FEES PAYABLE TO ACP
 
    Fees in the amount of $0.8 million  were paid to ACP in 1995 for  investment
banking services provided in connection with the acquisitions of Mascot, CRS and
King-O-Matic. The Company has also agreed to pay to ACP a base annual management
fee  of  $500,000 for  advisory and  consulting services  pursuant to  a written
management services agreement (the "Management Services Agreement"). ACP is also
entitled  to  reimbursements  from  the  Company  for  all  of  its   reasonable
out-of-pocket  costs and expenses incurred in connection with the performance of
its obligations  under  the  Management  Services  Agreement.  The  base  annual
management  fee is subject  to increase, at the  discretion of the disinterested
members of the Company's Board of Directors,  by up to an aggregate of  $250,000
in  the  event  the  Company  consummates  one  or  more  significant  corporate
transactions. The base annual  management fee was not  increased as a result  of
the acquisitions of CRS, Mascot and King-O-Matic. The base annual management fee
is  also subject  to increase  for specified  cost of  living increases.  If the
Company's  EBITDA   (earnings   before   interest,   taxes,   depreciation   and
amortization)  in any year exceeds management's budgeted EBITDA by 15.0% or more
for that year,  ACP will  be entitled to  receive an  additional management  fee
equal  to one half of its base annual  management fee for such year. Because the
Company's EBITDA did not exceed management's  budgeted EBITDA by 15.0% in  1995,
ACP  did not receive  this additional management  fee in 1995.  In the event the
Company consummates  any  significant  corporate  transaction  (which  will  not
include  this Offering), ACP will be entitled  to receive a closing fee from the
Company  equal  to  2.0%  of  the   first  $75.0  million  of  the   acquisition
consideration  (including debt assumed and current  assets retained) and 1.0% of
acquisition consideration (including debt  assumed and current assets  retained)
in  excess of $75.0  million. Notwithstanding the foregoing,  no payment will be
made to  ACP pursuant  to the  Management Services  Agreement at  any time  that
certain  events of default shall have occurred  and be then continuing under any
of the Indentures governing the Senior Notes or the Revolving Credit  Agreement.
The  Management Services Agreement also provides  that the Company shall provide
ACP and  its  directors,  employees,  partners  and  affiliates  with  customary
indemnification  against all actions  not involving gross  negligence or willful
misconduct. The base annual management fee payable to ACP will be reduced as the
collective beneficial ownership of Common Stock  by AEP and AOEP declines  below
50%:  for any period during which the collective beneficial ownership of AEP and
AOEP is less than 50% but at  least 40%, the base annual management fee  payable
for the period will be reduced 20%; for any period during which AEP's and AOEP's
collective  beneficial ownership  is less  than 40% but  at least  30%, the base
annual management fee payable for  the period will be  reduced 20% from the  fee
paid  in the  previous period;  and for any  period during  which the collective
beneficial ownership of AEP and AOEP is less than 30% but at least 20%, the base
annual management fee payable for  the period will be  reduced 20% from the  fee
paid  in the prior  period. If AEP's and  AOEP's collective beneficial ownership
declines below  20%,  the  Management Services  Agreement  will  terminate.  For
information  regarding the general  and certain of the  limited partners of ACP,
see "Ownership of Voting Securities."
 
FACILITY LEASES
 
    In connection with its  acquisition of Aaron's, the  Company entered into  a
lease  with  CRW, Inc.,  an  affiliate of  C.R. Wehr  and  James R.  Wehr (whose
individual family trusts owned all of  the outstanding capital stock of  Aaron's
prior  to its acquisition by the  Company), for Aaron's headquarters and primary
remanufacturing facility located in Springfield,  Missouri with an initial  term
beginning as of January 1, 1994 and expiring as of December 31, 2004, subject to
the  Company's option to extend the term for a period of five years. The monthly
base rent is $33,105 and the  Company is responsible for paying property  taxes,
insurance  and maintenance  expenses for the  leased premises.  The Company also
entered into three  leases with C.R.  Wehr, Westway Partnership,  JRW, Inc.  and
C.J.  Cates Real Estate Co. (each, an affiliate  of C.R. Wehr and James R. Wehr)
for three manufacturing facilities  comprising approximately 84,000 square  feet
for  an aggregate rent of $12,000 per month with an initial term beginning as of
January 1, 1994 and expiring as of
 
                                       42
<PAGE>
December 31, 1996 and December 31,  1998 (depending upon the facility),  subject
to the Company's option to extend the term of the lease for a 30,000 square foot
facility  for one successive period of five  years through December 31, 2003. In
November 1994, the Company entered into another lease with the same parties  for
a  98,800 square foot storage facility for monthly rent of $7,300 per month. The
initial term  of  the lease  expired  during 1995  and  pursuant to  its  terms,
continues as a month-to-month lease until terminated. The Company is responsible
for  paying property taxes, insurance and maintenance expenses for each of these
leased premises. James R. Wehr is an executive officer of the Company.
 
    In addition, the Company recently entered into a new lease with Patricia  L.
Bridgeforth,  Mr. Wehr's sister. The lease  for Aaron's 200,000 square foot core
storage facility has an  initial term of ten  years, expiring October 31,  2006,
with an option to renew for five years. The base monthly rent is $35,833 for the
initial  term, with  specified increases for  each renewal term.  The Company is
also required to pay taxes, maintenance and operating expenses.
 
    Prior to its acquisition by the Company, RPM was a party to numerous written
leases with a  general partnership  consisting of the  former RPM  shareholders.
Aggregate  rent with respect to these leases was approximately $61,975 per month
as of July 31, 1994 and  the premises consisted of approximately 246,300  square
feet  in  the  aggregate.  RPM's  former  headquarters,  primary remanufacturing
facility and several storage  facilities comprised approximately 109,300  square
feet  and were located in Azusa, California (approximately 30 miles northeast of
Los Angeles) (the  "Azusa Facilities").  In connection with  its acquisition  of
RPM, the Company entered into leases with that general partnership for the Azusa
Facilities  for an  initial one  year term  from July  19, 1994,  subject to the
Company's option to extend the term for three successive six-month periods.  The
aggregate  monthly rent payment  on the Azusa Facilities  was $27,325. The other
137,000 square feet of properties previously leased by such general  partnership
to  RPM were also leased to the Company  for an initial term of three years from
July 19, 1994, subject  to the Company's  option to cancel  the lease after  one
year.  The  lease for  the Azusa  Facilities expired  on July  19, 1995  and the
Company canceled the lease for the other 137,000 square feet of properties as of
such date, and RPM's operations were relocated to Rancho Cucamonga,  California.
At  such  time a  new lease  for  an Azusa  distribution facility  consisting of
approximately  6,000  square  feet  was   entered  into  with  the  former   RPM
shareholders  for an initial term of three  years with an aggregate monthly rent
payment of $1,450.
 
    Mascot is a  party to  a lease  with The  Estate of  Murray Schwartz,  Barry
Schwartz,  Bernard  Schwartz and  Bertha  Schwartz for  Mascot's remanufacturing
facility located in Mississauga, Ontario. Rent payments under such lease for the
approximately  35,100  square  foot  facility  are  $9,505  Canadian  per  month
beginning  as of  October 1,  1993 and  expiring as  of September  30, 1998. The
Company has an option to extend the term  for a period of five years subject  to
renegotiation  of the annual rent amount.  The Company is responsible for paying
property taxes,  insurance and  maintenance expenses  for the  leased  premises.
Barry Schwartz is an executive officer of the Company.
 
PAYMENT OF PREFERRED STOCK REORGANIZATION CONSIDERATION
 
    Upon  the  effectiveness of  the Reorganization,  each outstanding  share of
Holdings Common Stock will be converted  into        shares of ATC Common  Stock
and  each outstanding share  of Holdings Preferred Stock  will be converted into
the right to receive the  Preferred Stock Reorganization Consideration in  cash,
which will be an amount in cash equal to $100.00 per share of Holdings Preferred
Stock  plus an amount equal  to accrued and unpaid dividends  to the date of the
Reorganization.  As   of  June   30,  1996,   the  aggregate   Preferred   Stock
Reorganization Consideration would be approximately $24 million. Certain holders
of  Holdings Preferred  Stock are affiliates  of the Company,  including AEP and
AOEP  and  will  receive  a  portion  of  the  Preferred  Stock   Reorganization
Consideration.  Certain  executive officers  of  the Company,  including Messrs.
Smith, Wehr and Hester, hold an aggregate of 12,563 shares of Holdings Preferred
Stock, and  certain  directors, including  Messrs.  Crowell, Hardy,  Larsen  and
Roeder,  directly hold an  aggregate of 612 shares  of Holdings Preferred Stock.
Mr. Crowell and Mr. Roeder may also be deemed to beneficially own the shares  of
Holdings  Preferred Stock  held by  AEP and  AOEP (see  footnotes 2  and 3 under
"Ownership of Voting Securities").

REGISTRATION RIGHTS
 
    The holders  of the  Company's outstanding  Common Stock  have been  granted
certain  registration rights pursuant to  a Stockholders' Agreement. See "Shares
Eligible for Future Sale" for a description of such rights.
 
                          DESCRIPTION OF CAPITAL STOCK
 
    Giving effect to  the Reorganization,  the authorized capital  stock of  ATC
consists  of       shares of Common Stock, par value $0.01 per share, and
shares of Preferred Stock, par value $0.01 per share ("Preferred Stock"). As  of
June  15, 1996, 2,000,000 shares of Common Stock were issued and outstanding and
were held of  record by  37 stockholders and  370,176 shares  were reserved  for
issuance  under outstanding options and warrants. As of the same date, no shares
of Preferred Stock were outstanding.
 
COMMON STOCK
 
    Each holder of Common Stock is entitled  to one vote for each share held  of
record  on each matter  submitted to a  vote of stockholders.  Holders of Common
Stock do  not  have  the right  to  cumulate  their votes  in  the  election  of
Directors.  Subject  to  preferences  that  may be  granted  to  the  holders of
Preferred Stock, each  holder of Common  Stock is entitled  to share ratably  in
distributions  to stockholders and  to receive ratably such  dividends as may be
declared by the Board of Directors out of funds legally available therefor  and,
in  the event of the  liquidation or dissolution of  the Company, is entitled to
share  ratably  in  all  assets  of  the  Company  remaining  after  payment  of
liabilities.  Holders of  Common Stock have  no conversion,  preemptive or other
subscription rights,  and  there  are  no  redemption  rights  or  sinking  fund
provisions  with respect to  the Common Stock. The  outstanding Common Stock is,
validly issued, fully paid and non-assessable.
 
    Additional shares of Common  Stock may be  issued from time  to time by  the
Company.  The Company's Certificate of Incorporation  provides that the Board of
Directors has no power to alter the  rights of any outstanding shares of  Common
Stock.  Certain other provisions  of the Company's  Certificate of Incorporation
affect the  rights  of holders  of  Common Stock  and  may have  the  effect  of
delaying, deferring or preventing a change in control of the Company.
 
PREFERRED STOCK
 
    The  Board of  Directors, without  further action  by the  holders of Common
Stock, may issue  shares of  Preferred Stock  and may  fix or  alter the  voting
rights,  redemption  provisions  (including sinking  fund  provisions), dividend
rights, dividend  rates,  liquidation  preferences, conversion  rights  and  the
designation  of and number of shares  constituting any wholly unissued series of
Preferred Stock.  The issuance  of Preferred  Stock could  adversely affect  the
voting  power and other rights of the holders of Common Stock. See "Risk Factors
- -- Control of the Company; Anti-Takeover Matters."
 
    The authority possessed by the Board  of Directors to issue Preferred  Stock
could  potentially be used to discourage attempts by others to obtain control of
the Company through a merger, tender offer, proxy contest or otherwise by making
such attempts more difficult to achieve  or more costly. The Board of  Directors
may issue Preferred Stock with voting and conversion rights that could adversely
affect  the voting power of the holders of Common Stock. There are no agreements
or understandings for the issuance of Preferred Stock and the Board of Directors
has no present intention to issue any Preferred Stock.
 
WARRANTS
 
    In August  1994,  the Company  issued  warrants  to Mr.  Myers  and  another
individual  to purchase an aggregate of 58,480 shares of Common Stock, which are
exercisable at any time.  In December 1994, the  Company issued warrants to  Dr.
Hartnett  to  purchase an  aggregate  of 11,696  shares  of Common  Stock, which
warrants vest one third annually beginning December 31, 1994.
 
    Each warrant, when  exercised, entitles  the holder thereof  to receive  the
number  of shares of Common Stock set forth on such Warrant at $10.00 per share.
The warrants will automatically expire on  the tenth anniversary of the date  of
grant.  The  exercise price  and the  number  of Warrant  Shares are  subject to
 
                                       44
<PAGE>
customary anti-dilution provisions  that are  effective upon  the occurrence  of
certain  events such  as stock splits  and stock  dividends. In the  event of an
issuance of Common Stock to either AEP, AOEP or their affiliates below the  fair
market  value of  the Common Stock  on the  date of such  issuance, the exercise
price of 58,480  of the  warrants and  the number  of shares  issuable upon  the
exercise  thereof will be adjusted accordingly; the other 11,696 warrants do not
contain this  adjustment provision.  In addition,  the warrants  are subject  to
customary  provisions regarding the assumption by a successor corporation in the
event of reorganization, reclassification, consolidation, merger or sale of  the
Company.  The issuance of Common  Stock pursuant to the  Offering will not cause
any adjustment in the warrants.
 
    The warrant  holders have  no right  to  vote on  matters submitted  to  the
stockholders  of the Company and have no right to receive dividends. The warrant
holders are not entitled to share in the  assets of the Company in the event  of
the liquidation or dissolution of the Company or the winding up of the Company's
affairs.
 
ANTI-TAKEOVER STATUTE
 
    Section  203 of  the DGCL  generally prohibits  a Delaware  corporation from
engaging in  a "business  combination" with  an "interested  stockholder" for  a
period  of three  years after the  date of  the transaction in  which the person
became an interested stockholder, unless (i)  prior to the date of the  business
combination,  the  transaction is  approved  by the  board  of directors  of the
corporation, (ii) upon  consummation of  the transaction which  resulted in  the
stockholder  becoming an interested stockholder, the interested stockholder owns
at least 85% of the outstanding voting stock, or (iii) on or after the date such
stockholder became  an  interested  stockholder,  the  business  combination  is
approved  by the board  and by the affirmative  vote of at least  66 2/3% of the
outstanding voting stock  which is not  owned by the  interested stockholder.  A
"business  combination" includes mergers, certain  asset sales and certain other
transactions resulting in a financial benefit to the stockholder. An "interested
stockholder" is a person who, together with affiliates and associates, owns  (or
within three years, did own) 15% or more of the corporation's voting stock.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company's Certificate of Incorporation limits the liability of directors
to  the maximum  extent permitted  by Delaware  law. Delaware  law provides that
directors of a company  will not be personally  liable for monetary damages  for
breach  of their fiduciary duties as directors, except for liability for (i) any
breach of their duty of loyalty to the company or its stockholders, (ii) acts or
omissions not in  good faith or  involving intentional misconduct  or a  knowing
violation  of  law,  (iii)  unlawful  payment  of  dividends  or  unlawful stock
repurchases or redemptions as provided  in Section 174 of  the DGCL or (iv)  any
transaction from which the director derived an improper personal benefit.
 
    The  Company's  Bylaws provide  that  the Company  shall  pay all  costs and
expenses (including legal expenses) incurred by and indemnify from any  monetary
liability  its  present  and former  officers  and  directors who  are  named or
threatened to be named, a party  to any administrative, civil, investigative  or
criminal  proceeding potentially seeking to impose  liability on such person for
acts alleged to have been committed by  such person while a director or  officer
of  the Company or  while serving at the  request of the  Company as a director,
officer, employee or agent of  another corporation, partnership, joint  venture,
trust  or other enterprise, unless  a determination is made  that the person did
not act in good  faith and in a  manner he reasonably believed  to be in or  not
opposed  to the best interests of the  Company, or, with respect to any criminal
action or  proceeding,  had no  reasonable  cause  to believe  his  conduct  was
unlawful.  Such determination shall be made (i)  by the Board by a majority vote
of a quorum consisting of directors who were not parties to such action, suit or
proceeding, or (ii) of such a quorum is not obtainable, or even if obtainable  a
quorum  of disinterested directors so directs, by independent legal counsel in a
written option, or (iii) by the stockholders of the Company. There is no  action
or  proceeding pending or, to the knowledge of the Company, threatened which may
result in a claim for indemnification by any director officer, employee or agent
of the Company.
 
    The Company believes that the provisions in its Certificate of Incorporation
and its Bylaws are necessary to attract and retain qualified persons as officers
and Directors.

                      DESCRIPTION OF CERTAIN INDEBTEDNESS
 
    The  materials terms  of certain indebtedness  of the  Company are described
below. Each  of the  following summaries  is  subject to  and qualified  in  its
entirety  by reference to  the detailed provisions  of the respective agreements

instruments  have been filed as exhibits  to the Registration Statement of which
this Prospectus is a part.
 
REVOLVING CREDIT AGREEMENT
 
    In July 1994 Company entered into a Revolving Credit Agreement with Chemical
Bank (the  "Bank") and  Heller Financial,  Inc. providing  for a  $30.0  million
revolving credit facility available to the Company for working capital purposes.
Subject  to  the  satisfaction  of  customary  conditions,  advances  under  the
Revolving Credit Agreement may be made, and letters of credit may be issued,  in
each case up to an aggregate of $30.0 million at any time prior to July 19, 1999
(the  "Termination Date"). The funds available to be advanced may not exceed the
aggregate of 85% of  the Company's eligible accounts  receivable and 60% of  the
Company's  eligible inventory, in  each case as defined  in the Revolving Credit
Agreement. All amounts advanced under the Revolving Credit Agreement become  due
and  payable  on  the  Termination Date.  The  Company  may  pre-pay outstanding
advances in whole or in part without incurring any premium or penalty.
 
    All obligations  of the  Company and  its subsidiaries  under the  Revolving
Credit Agreement are secured by a first priority security interest in all of the
accounts  receivable and  inventory of the  Company and its  existing and future
subsidiaries.  The  obligations  of  the  Company  under  the  Revolving  Credit
Agreement   are  guaranteed  by  each  of  the  Company's  existing  and  future
subsidiaries.
 
    At the  Company's  election, amounts  advanced  under the  Revolving  Credit
Agreement will bear interest at either (i) the Alternate Base Rate plus 1.5%, or
(ii)  the Eurodollar Rate plus  2.5%. The "Alternate Base  Rate" is equal to the
highest of  (a)  the  Bank's prime  rate,  (b)  the secondary  market  rate  for
three-month  certificates of deposit  plus 1.0%, and (c)  the federal funds rate
plus 0.5%, in each case as in effect from time to time. The "Eurodollar Rate" is
the rate offered by the Bank for eurodollar deposits for one, two, three or  six
months  (as selected by the  Company) in the interbank  eurodollar market in the
approximate amount of the Bank's share of the advance under the Revolving Credit
Agreement. Interest  payments on  advances which  bear interest  based upon  the
Alternate  Base Rate are due  quarterly in arrears and  on the Termination Date,
and interest payments on advances which bear interest based upon the  Eurodollar
Rate  are due  on the  last day of  each relevant  interest period  (or, if such
period exceeds three months, quarterly after the first day of such period).
 
    The Revolving Credit Agreement  contains extensive affirmative and  negative
covenants,  including, among others, covenants relating  to levels of net worth,
leverage, EBITDA and cash flow coverage and certain limits on the ability of the
Company to incur indebtedness, make  capital expenditures, create liens,  engage
in  mergers and consolidations, make restricted payments, make asset sales, make
capital expenditures or investments, issue stock and engage in transactions with
affiliates of the Company and  its subsidiaries. The Revolving Credit  Agreement
also contains customary events of default provisions.
 
    The  Company paid the Bank  a one time facility  and commitment fee upon the
effectiveness of the Revolving Credit Agreement and is required to pay the  Bank
quarterly  in arrears a  commitment fee equal  to 0.5% per  annum of the average
daily unused portion of the Revolving Credit Agreement during such quarter.  The
Company  must also reimburse the  Bank for certain legal  and other costs of the
Bank and pay a fee on outstanding letters of credit at a per annum equal to  the
applicable margin then in effect for advances bearing interest at the Eurodollar
Rate.

SENIOR NOTES
 
    GENERAL.   ATC's  $120,000,000 aggregate  principal amount  of its  Series B
Notes and $40,000,000  aggregate principal  amount of  its Series  D Notes  were
issued  pursuant to an Indenture dated August 2, 1994, by and among ATC, each of
ATC's subsidiaries  and  American Bank  National  Association, as  trustee.  The
Senior  Notes are  fully and unconditionally  guaranteed on a  joint and several
basis  by  each  of  ATC's  subsidiaries.  Each  series  of  Senior  Notes   has
substantially identical terms. The Senior Notes may be redeemed at the option of
the  Company in whole or in part at (a) 106% of the principal amount redeemed on
or after August 1, 1999 but prior to  August 1, 2000, (b) 104% of the  principal
amount redeemed on or after August 1, 2000 but prior to August 1, 2001, (c) 102%
of  the principal amount redeemed on or after August 1, 2001 but prior to August
1, 2002 or (d) 100% of the principal amount redeemed on or after August 1,  2002
through  maturity,  in  each case  plus  accrued  and unpaid  interest,  if any.
Notwithstanding the foregoing, at any time prior to August 1, 1997, the  Company
may  also redeem up to $30 million and $10 million in aggregate principal amount
of the Series B Notes and Series D Notes, respectively, at 112% of the principal
amount redeemed  with the  net cash  proceeds  from one  or more  public  equity
offerings of the Company, and intends to do so in connection with the Offering.
 
    The  Indentures  governing  the  Senior  Notes  contain  various restrictive
covenants that,  among  other  things,  limit: (i)  the  incurrence  of  certain
additional indebtedness by the Company or its subsidiaries; (ii) the creation of
Senior  Debt of  the Company which  is, by  its terms, subordinated  in right of
payment to other indebtedness of the Company; and (iii) the payment of dividends
on capital  stock of  the Company  and its  subsidiaries (see  "Risk Factors  --
Absence   of  Dividends").  Affirmative  covenants  include,  among  others,  an
obligation to pay principal, interest and premium, if any, when due, hold  funds
for  note  payments in  trust, maintain  its  corporate existence,  maintain its
properties in good condition, pay taxes when due, furnish to the trustee  copies
of  certain financial information, and  certify as to whether  the Company is in
default within 120 days after the end of each fiscal year of the Company. Events
of default under the Indentures governing the Senior Notes include, among  other
things:  (i) a default  in the payment of  any interest on  any Senior Note when
due, which default continues for 30 days;  (ii) a default in the payment of  any
principal  of or premium, if any, on any Senior Note when due; (iii) the failure
by the  Company to  comply with  any  agreement or  covenant in  the  Indentures
governing  the Senior Notes, which failure continues  for 30 days after a Notice
of Default (as defined in the  Indentures governing the Senior Notes) is  given;
(iv)  final unsatisfied judgments  in excess of  $2.5 million (excluding amounts
covered by insurance) not discharged, waived or stayed for 60 days; (v)  default
under indebtedness of the Company or any of its subsidiaries, which indebtedness
has a principal amount of over $2.5 million either resulting from the failure to
pay  principal  at  maturity  or as  a  result  of which  the  maturity  of such
indebtedness has been accelerated prior to its stated maturity; and (vi) certain
events of bankruptcy, insolvency or reorganization of the Company or any of  its
subsidiaries.
 
    CHANGE  OF CONTROL  PUT.  Upon  the occurrence  of a Change  of Control, the
Company will be required to  make an offer to repurchase  the Senior Notes at  a
price  equal to 101% of the principal  amount thereof, together with accrued and
unpaid interest thereon. A  "Change of Control"  is defined as  (i) any sale  or
transfer  of  all  or substantially  all  of the  assets  of the  Company,  on a
consolidated basis, in one transaction or a series of related transactions,  if,
immediately  after giving effect to such transaction, any person (other than the
Company, its subsidiaries or certain other entities related to ACP (an "Excluded
Person")) is or becomes the "beneficial owner," directly or indirectly, of  more
than  35% of  the total voting  power, (ii)  any person (other  than an Excluded
Person) is or becomes  the "beneficial owner," directly  or indirectly, of  more
than  35%  of  the  total  voting  power in  the  aggregate  of  all  classes of
outstanding capital stock of  the Company unless the  percentage so owned by  an
Excluded Person is greater. The occurrence of the Offering will not constitute a
"Change of Control" for purposes of the Senior Notes.
 
    In  addition, indebtedness under  the Indentures governing  the Senior Notes
and the Revolving  Credit Agreement would  be accelerated or  trigger a  similar
repurchase  right upon  a change  of control,  as defined  in the  relevant debt
instrument, and  other  debt the  Company  may  incur could  contain  a  similar
provision. In the event of any such occurrence, the Company would be required to
repay   such  indebtedness.  See  "Risk  Factors  --  Control  of  the  Company,
Antitakeover Matters."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have            shares  of
Common  Stock outstanding. The           shares sold in the Offering (
shares if the Underwriters' over-allotment option is exercised in full) will  be
freely  tradable without  restriction under the  Securities Act,  except for any
such shares held at any time by an  "affiliate" of the Company, as such term  is
defined under Rule 144 promulgated under the Securities Act.
 
    The  2,000,000  shares of  Common  Stock outstanding  immediately  prior the
consummation of the  Offering were  issued in  private transactions  and may  be
publicly  sold only if registered under the Securities Act or sold in accordance
with an applicable exemption  from registration, such as  Rule 144. In  general,
under  Rule 144,  as currently  in effect, a  person who  has beneficially owned
shares for at least two years, including an "affiliate," as that term is defined
in Rule 144, is  entitled to sell,  within any three-month  period, a number  of
"restricted"  shares that does not exceed the greater of one percent (1%) of the
then outstanding shares of Common Stock (          shares immediately after  the
Offering)  or the average  weekly trading volume during  the four calendar weeks
preceding such sale. Sales under Rule 144 are subject to certain manner of  sale
limitations,   notice  requirements  and  the  availability  of  current  public
information about the  Company. Rule 144(k)  provides that a  person who is  not
deemed  an "affiliate" and who has beneficially  owned shares for at least three
years is entitled to sell such shares at any time under Rule 144 without  regard
to the limitations described above.
 
    The Company currently has outstanding warrants and employee stock options to
purchase  an aggregate  of 324,639 shares  of Common Stock.  The shares issuable
upon the exercise of such warrants  and options will be "restricted" shares  for
Rule 144 purposes.
 
    The   parties  to  a  Stockholders  Agreement  among  the  Company  and  its
stockholders,  certain  of  its  optionholders  and  its  warrant  holders  (the
"Stockholders  Agreement"), who  in the  aggregate held  all of  the outstanding
shares of  Common  Stock  as  of  March 31,  1996,  have  been  granted  certain
"piggy-back"  registration rights with respect to  shares of the Common Stock in
connection with  a qualified  initial  public offering  by  the Company  and  in
connection  with certain secondary public offerings effected by the Company. The
Company will bear all expenses incident to any such registration, including  the
fees  and expenses  of a  single counsel  retained by  the selling stockholders;
however, each  selling  stockholder will  be  responsible for  the  underwriting
discounts  and commissions and transfer taxes  in connection with shares sold by
such stockholder. Each  selling stockholder  and the  underwriters through  whom
shares are sold on behalf of a selling stockholder will be entitled to customary
indemnification   from  the  Company   against  certain  liabilities,  including
liabilities under the Securities Act.
 
    The Company  will agree  with  the Underwriters  not  to sell  or  otherwise
dispose  of any shares of Common Stock for a period of 180 days from the date of
this Prospectus  without the  prior  written consent  of  Morgan Stanley  &  Co.
Incorporated.  Each of the Company's  current stockholders, directors, executive
officers and warrant holders will enter into or is bound by a similar agreement.
See "Underwriters."
 
    The Company is unable to estimate the  number of shares that may be sold  in
the  future by the  existing stockholders or  the effect, if  any, that sales of
shares by such stockholders will  have on the market  price of the Common  Stock
prevailing  from time to time.  Sales of substantial amounts  of Common Stock by
such stockholders could adversely affect prevailing market prices.
 
                 CERTAIN UNITED STATES FEDERAL TAX CONSEQUENCES
                          TO NON-UNITED STATES HOLDERS
 
    The following is a general discussion  of certain United States Federal  tax
consequences  of the acquisition, ownership, and disposition of the Common Stock
by an initial purchaser that, for United States Federal income tax purposes,  is
not  a "United States person" (a "Non-United States Holder"). This discussion is
based upon the United States Federal tax law now in effect, which is subject  to
change,  possibly  retroactively. For  purposes  of this  discussion,  a "United
States person" means a citizen or resident of the United States, a  corporation,
partnership,  or other entity created or organized in the United States or under
the laws of the
 
                                       48
<PAGE>
United States or  of any political  subdivision thereof, or  an estate or  trust
whose  income is includible in gross income for United States Federal income tax
purposes regardless  of  its  source.  This discussion  does  not  consider  any
specific facts or circumstances that may apply to a particular Non-United States
Holder.  Prospective investors are urged to consult their tax advisors regarding
the United States Federal tax consequences of acquiring, holding, and  disposing
of  Common Stock, as well as any tax  consequences that may arise under the laws
of any foreign, state, local, or other taxing jurisdiction.
 
DIVIDENDS
 
    Dividends on Common Stock paid to a Non-United States Holder generally  will
be  subject to withholding  of United States  Federal income tax  at the rate of
30%, unless  the withholding  rate is  reduced under  an applicable  income  tax
treaty  between  the United  States  and the  country  of tax  residence  of the
Non-United States Holder. The 30% withholding tax will not apply if the dividend
is effectively connected with  a trade or business  conducted within the  United
States  by the Non-United States Holder  (or, alternatively, where an income tax
treaty applies,  if  the dividend  is  effectively connected  with  a  permanent
establishment  maintained  within the  United  States by  the  Non-United States
Holder), but, instead, the dividend will be subject to the United States Federal
income tax  on net  income that  applies  to United  States persons  (and,  with
respect  to corporate holders, also may be subject to the branch profits tax). A
Non-United States  Holder  may  be required  to  satisfy  certain  certification
requirements in order to claim treaty benefits or to otherwise claim a reduction
of  or exemption from withholding under the foregoing rules. A Non-United States
Holder that is eligible for a reduced rate of U.S. withholding tax pursuant to a
tax treaty may  obtain a  refund of  any excess  amounts withheld  by filing  an
appropriate claim for refund with the United States Internal Revenue Service.
 
GAIN ON DISPOSITION
 
    A  Non-United States Holder  will generally not be  subject to United States
Federal  income  tax  on  gain  recognized  on  a  sale,  redemption,  or  other
disposition  of Common Stock  unless (i) the gain  is effectively connected with
the conduct of a trade  or business within the  United States by the  Non-United
States  Holder, or  (ii) in  the case  of a  Non-United States  Holder who  is a
nonresident alien individual and holds the Common Stock as a capital asset, such
holder is present in the United States for 183 or more days in the taxable  year
and certain other requirements are met.
 
    Also,  special rules apply to Non-United States Holders if the Company is or
becomes a "United States  real property holding  corporation" for United  States
Federal income tax purposes. In general, gain on the disposition of interests in
a  United States real  property holding corporation is  subject to United States
Federal income tax.  A corporation is  generally a United  States real  property
holding  corporation if the fair market value of its United States real property
interests equals or exceeds 50  percent of the sum of  the fair market value  of
its worldwide real property interests plus its other assets used or held for use
in  a trade of  business. The Company believes  it is not  currently, and is not
likely to become, a United States  real property holding corporation for  United
States Federal income tax purposes.
 
FEDERAL ESTATE TAXES
 
    Common Stock owned or treated as owned by an individual who is not a citizen
or  resident  (as  specifically defined  for  United States  Federal  estate tax
purposes) of the United States at the date of death, or Common Stock subject  to
certain  lifetime transfers made by such an individual, will be included in such
individual's estate for  United States Federal  estate tax purposes  and may  be
subject  to United  States Federal estate  tax, unless an  applicable estate tax
treaty provides otherwise. Estates of nonresident aliens are generally allowed a
credit that is equivalent to an exclusion of $600,000 of assets from the  estate
for United States Federal estate tax purposes.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
    The  Company  must report  to the  holders of  the Common  Stock and  to the
Internal Revenue Service  the amount of  any dividends paid  on Common Stock  in
each calendar year and the amounts of tax withheld, if any, with respect to such
payments.  That information may also be made available to the tax authorities of
the country in which a Non-United States Holder resides.
 
                                       49
<PAGE>
    Under  temporary   United  States   Treasury  regulations,   United   States
information reporting requirements and backup withholding tax will generally not
apply  to dividends  paid on  the Common  Stock to  a Non-United  States Holder.
Payments by a United States office of a broker of the proceeds of a sale of  the
Common  Stock  is  subject to  both  backup withholding  at  a rate  of  31% and
information reporting unless the holder  certifies its Non-United States  Holder
status  under  penalties  of  perjury  or  otherwise  establishes  an exemption.
Information reporting requirements (but not backup withholding) will also  apply
to  payments of the proceeds of sales of  the Common Stock by foreign offices of
United States brokers, or foreign brokers with certain types of relationships to
the United States,  unless the broker  has documentary evidence  in its  records
that  the holder is a Non-United States  Holder and certain other conditions are
met, or the holder otherwise establishes an exemption.
 
    Backup withholding is not an additional tax. Any amounts withheld under  the
backup  withholding rules  will be refunded  or credited  against the Non-United
States Holder's United States  Federal income tax  liability, provided that  the
required information is furnished to the Internal Revenue Service.
 
    These information reporting and backup withholding rules are under review by
the  United States Treasury and  their application to the  Common Stock could be
changed by  future regulations.  On  April 15,  1996,  the IRS  issued  proposed
Treasury Regulations concerning the withholding of tax and reporting for certain
amounts  paid to non-resident individuals and foreign corporations. The proposed
Treasury Regulations, if adopted in their  present form, would be effective  for
payments  made  after December  31, 1997.  Prospective investors  should consult
their tax advisors concerning the  potential adoption of such proposed  Treasury
Regulations and the potential effect on their ownership of the Common Stock.
 
    THE  FOREGOING IS INTENDED ONLY  AS A SUMMARY OF  CERTAIN FEDERAL INCOME TAX
ASPECTS OF HOLDING COMMON STOCK AND IS NOT A SUBSTITUTE FOR CAREFUL TAX PLANNING
AND ADVICE BASED UPON THE INDIVIDUAL CIRCUMSTANCES OF THE HOLDER.

</TABLE>
 
    The Underwriting  Agreement provides  that the  obligations of  the  several
Underwriters  to  pay for  and accept  delivery  of the  shares of  Common Stock
offered hereby are subject to the  approval of certain legal matters by  counsel
and  to certain  other conditions, including  the conditions that  no stop order
suspending the  effectiveness  of  the  Registration  Statement  of  which  this
Prospectus  is  a part  is in  effect and  no proceedings  for such  purpose are
pending before or threatened by the Securities and Exchange Commission and  that
there  has  been  no material  adverse  change  or any  development  involving a
prospective material  adverse change  in the  business, financial  condition  or
results  of operations of ATC and its  subsidiaries, taken as a whole, from that
set forth in such Registration Statement. The Underwriters are obligated to take
and pay for all of the shares  of Common Stock offered hereby (other than  those
covered by the over-allotment option described below) if any are taken.
 
    The Underwriters propose to offer part of the shares of Common Stock offered
hereby  directly to  the public at  the public  offering price set  forth on the
cover page hereof  and part to  certain dealers  at a price  which represents  a
concession  not in excess of $       per  share under the public offering price.
Any Underwriter may allow,  and such dealers may  re-allow, a concession not  in
excess of $      per share to other Underwriters or to certain other dealers.
 
    Pursuant  to  the Underwriting  Agreement, the  Company  has granted  to the
Underwriters  an  option,  exercisable  for  30  days  from  the  date  of  this
Prospectus,  to purchase up to an additional           shares of Common Stock at
the public offering price set forth on the cover page hereof, less  underwriting
discounts and commissions. The Underwriters may exercise such option to purchase
solely for the purpose of covering over-allotments, if any, incurred in the sale
of  the shares  of Common  Stock offered  hereby. To  the extent  such option is
exercised,  each  Underwriter   will  become  obligated,   subject  to   certain
conditions,  to purchase  approximately the  same percentage  of such additional
shares as the number set forth next to such Underwriter's name in the  preceding
table  bears  to the  total  number of  shares of  Common  Stock offered  by the
Underwriters hereby.
 
    The Underwriters have informed the Company that they do not intend sales  to
discretionary  accounts to exceed five percent of  the total number of shares of
Common Stock offered by them.
 
    The Company, on the one hand, and the Underwriters, on the other hand,  have
agreed   to  indemnify   each  other  against   certain  liabilities,  including
liabilities under the Securities Act.
 
    The Company  will agree  in the  Underwriting Agreement  that it  will  not,
without  the prior written consent of  Morgan Stanley & Co. Incorporated, offer,
pledge, sell,  contract  to sell,  sell  any  option or  contract  to  purchase,
purchase  any option or contract to sell,  grant any option, right or warrant to
purchase, or  otherwise transfer  or  dispose of,  directly or  indirectly,  any
shares   of  Common  or  any  securities  convertible  into  or  exercisable  or
exchangeable for Common Stock or enter  into any swap or other arrangement  that
transfers  to another, in whole on in  part, any of the economic consequences of
ownership of the Common Stock, for a period  of 180 days after the date of  this
Prospectus.  Each of  the Company's  current stockholders,  directors, executive
officers and warrant holders will enter into or is bound by a similar agreement.
 
                                       51

    At the  request  of  the  Company, the  Underwriters  have  reserved  up  to
          shares  of the shares of  Common Stock offered hereby  for sale at the
public offering  price  to certain  directors,  officers and  employees  of  the
Company.  The number of shares of Common Stock available for sale to the general
public will be reduced to the extent such persons purchase such reserved shares.
Any reserved shares not so purchased will be offered by the Underwriters to  the
general  public  on the  same  basis as  the  other shares  offered  hereby. All
purchasers of the shares of Common Stock reserved pursuant to this paragraph who
are also directors  or executive  officers of the  Company will  be required  to
enter  into agreements identical to those described in the immediately preceding
paragraph restricting the  transferability of such  shares for a  period of  180
days after the date of this Prospectus.
 
PRICING OF THE OFFERING
 
    Prior  to the Offering,  there has been  no public market  for the shares of
Common Stock  of  the  Company.  The  initial  public  offering  price  will  be
determined by negotiation between the Company and the Representatives. Among the
factors  considered in determining the initial public offering price will be the
future prospects of the Company and its industry in general, sales, earnings and
certain other  financial and  operating  information of  the Company  in  recent
periods,  and the  price-earnings ratios,  price-sales ratios,  market prices of
securities and certain financial and operating information of companies  engaged
in  activities similar  to those  of the  Company. The  estimated initial public
offering price range set forth on the cover page of this preliminary  Prospectus
is subject to change as a result of market conditions and other factors.
 
                                 LEGAL MATTERS
 
    The  validity of the issuance  of the shares of  Common Stock offered hereby
will be passed upon for the Company by Gibson, Dunn & Crutcher LLP, Los Angeles,
California. Upon consummation of the  Initial Acquisitions, certain partners  of
Gibson, Dunn & Crutcher LLP acquired beneficial interests in shares representing
in  the aggregate less than 1% of all outstanding Common Stock at the same price
per share paid by  other purchasers of  Common Stock on or  prior to that  date.
Certain  matters in  connection with  the Offering will  be passed  upon for the
Underwriters by Skadden, Arps, Slate, Meagher & Flom, Los Angeles, California.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
Stockholders and Board of Directors
Aftermarket Technology Corp.
 
    We  have audited the accompanying consolidated balance sheets of Aftermarket
Technology Corp. (the Company) as of December 31, 1994 and 1995, and the related
consolidated statements of income, stockholders' equity, and cash flows for  the
five  months ended December 31, 1994, and  for the year ended December 31, 1995.
We  have  also   audited  the  accompanying   combined  statements  of   income,
stockholders' equity, and cash flows of the Predecessor Companies to Aftermarket
Technology  Corp. (the  Predecessor Companies) for  the year  ended December 31,
1993 and for the  seven months ended July  31, 1994. These financial  statements
are  the responsibility of the Company's and Predecessor Companies' managements.
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.
 
    In  our opinion, the financial statements  referred to above present fairly,
in all material  respects, the  consolidated financial  position of  Aftermarket
Technology  Corp. at December 31, 1994 and 1995, and the consolidated results of
the Company's operations and cash flows  for the five months ended December  31,
1994,  and for the year ended December 31,  1995 and the combined results of the
operations of  the Predecessor  Companies to  Aftermarket Technology  Corp.  and
their  cash flows for the year ended December 31, 1993, and for the seven months
ended  July  31,  1994,  in   conformity  with  generally  accepted   accounting
principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
        (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1995 AND 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
    The  consolidated  financial  statements  of  Aftermarket  Technology  Corp.
include the combined results of Aftermarket Technology Holdings Corp. (Holdings)
and  its   wholly  owned   subsidiary,   Aftermarket  Technology   Corp.   (ATC)
(collectively,  the "Company"). Concurrent with the completion of ATC's proposed
initial public  offering, Holdings  will be  merged into  ATC. The  accompanying
financial  statements are presented on a  combined basis with the elimination of
intercompany  accounts  and  transactions  and  will  represent  the  historical
financial statements of ATC upon the completion of the merger.
 
    The  consolidated financial statements include  the results of the following
remanufactured automotive products businesses which sell to customers throughout
the United States and Canada: (i) Aaron's Automotive Products, Inc. (Aaron's), a
Springfield, Missouri  based remanufacturer  of transmissions,  engines,  torque
converters,  and  other  drive  train parts  for  automotive  original equipment
manufacturers, independent rebuilders and  distributors, and retail chain  store
customers;  (ii)  Component  Remanufacturing Specialists  (CRS),  a  Mahwah, New
Jersey based  remanufacturer  and  distributor of  automotive  drive  train  and
transmission  components; (iii) H.T.P., Inc. (HTP), a Louisville, Kentucky based
remanufacturer and warehouse  distributor of  new and  remanufactured parts  for
independent  transmission  rebuilders; (iv)  Mamco  Converters, Inc.  (Mamco), a
Dayton,  Ohio  based  remanufacturer   of  torque  converters  for   independent
transmission  rebuilders  and distributors;  (v)  King-O-Matic and  Mascot Truck
Parts  Inc.  (Mascot),  Canadian  based  remanufacturers  and  distributors   of
automotive  components  and  a  rebuilder  of  heavy  duty  truck transmissions,
respectively, are located in  Mississauga, Canada; and (vi)  RPM Merit (RPM),  a
Rancho  Cucamonga, California (formerly  Azusa, California) based remanufacturer
of torque converters, constant velocity axles, and transmission fluid pumps, and
a warehouse distributor of remanufactured parts and new part kits to independent
transmission rebuilders.
 
    The  combined  financial   statements  of  the   Predecessor  Companies   to
Aftermarket   Technology  Corp.   (the  Predecessor   Companies)  represent  the
combination of the  historical financial  statements of Aaron's,  RPM, HTP,  and
Mamco.  The Company was formed for the  purpose of effecting the acquisitions of
the Predecessor Companies and is a wholly owned subsidiary of Holdings. Holdings
does not  have any  operations other  than its  investment in  the Company.  The
Predecessor   Companies  were  acquired  pursuant   to  four  separate  purchase
agreements for  a total  purchase  price of  approximately $160.4  million  (the
Initial  Acquisitions). The combined  financial statements for  the seven months
ended July 31, 1994  include the operations of  the Predecessor Companies up  to
their respective closing dates, which approximated July 31, 1994.
 
INTERIM FINANCIAL INFORMATION
 
    The  financial information at March 31, 1996  and for the three months ended
March 31, 1995 and  1996 is unaudited but  includes all adjustments  (consisting
only of normal recurring adjustments) that the Company considers necessary for a
fair  presentation  of the  financial position  at such  date and  the operating
results and cash flows for those periods. Operating results for the three months
ended March 31, 1996 are not necessarily  indicative of the results that may  be
expected for the entire year.
 
PRINCIPLES OF CONSOLIDATION
 
    The  Company's acquisitions  have been accounted  for as  purchases, and the
consolidated financial statements for the twelve months ended December 31,  1995
and  five months ended December  31, 1994 include operations  of the Company and
its  wholly  owned  operating  subsidiaries  from  the  dates  of   acquisition.
Significant  intercompany  accounts  and transactions  have  been  eliminated in
consolidation.
 
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with original maturities
of one year or less to be cash equivalents.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
        (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1995 AND 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
USE OF ESTIMATES
 
    The preparation of  the financial  statements in  conformity with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that affect  the amounts  reported in the  financial statements  and
accompanying notes. Actual results could differ from those estimates.
 
INVENTORIES
 
    Inventories  are stated at the lower of cost (first-in, first-out method) or
market and consist primarily of new and used engine and transmission parts,  and
cores  and finished goods. Appropriate  consideration is given to deterioration,
obsolescence, and other factors in evaluating estimated market value.
 
EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
    Equipment and leasehold  improvements are  stated at  cost. Depreciation  is
computed  using accelerated and straight-line  methods over the estimated useful
lives of the assets, which range from three to fifteen years.
 
FOREIGN CURRENCY TRANSLATION
 
    The financial statements of Canadian subsidiaries have been translated  into
U.S. dollars in accordance with SFAS No. 52, "Foreign Currency Translation." All
balance  sheet accounts have been translated  using the exchange rates in effect
at the balance sheet date. Income  statement amounts have been translated  using
the  average exchange rate for the year. The translation gain resulting from the
changes in  exchange  rates has  been  reported  separately as  a  component  of
stockholders' equity.
 
    The  effect on the  statements of income  of transaction gains  or losses is
insignificant for the periods presented.
 
DEBT ISSUANCE COSTS
 
    Debt issuance costs incurred in connection with the sale of the 12% Series B
and Series D Senior  Subordinated Notes (Note 6)  and Revolving Credit  Facility
(Note  5) are being amortized over the life  of the debt of ten, nine, and seven
years, respectively.
 
COST IN EXCESS OF NET ASSETS ACQUIRED
 
    The excess of the purchase price over the fair value of the assets purchased
is being amortized over 40 years on a straight-line basis. Cost in excess of net
assets acquired is reflected net  of accumulated amortization of $1,199,809  and
$4,466,669 at December 31, 1994 and 1995, respectively.
 
    In  accordance  with  SFAS  No.  121,  "Accounting  for  the  Impairment  of
Long-Lived Assets and  for Long-Lived  Assets to  be Disposed  of," the  Company
assesses  the  recoverability  of  cost  in excess  of  net  assets  acquired by
determining whether the  amortization of  the asset balance  over its  remaining
life  can be recovered  through the undiscounted future  operating cash flows of
the acquired operation. The amount of the impairment, if any, is measured  based
on  projected discounted future operating cash  flows. The Company believes that
no impairment has occurred and that no reduction in the estimated useful life is
warranted.
 
CREDIT POLICY
 
    The Company  grants credit  to certain  customers who  meet  pre-established
credit  requirements.  The  Company  maintains a  credit  policy  which requires
certain customers to pay for products upon delivery. Credit losses are  provided
for  in the financial statements and  consistently have been within management's
expectations.

        (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1995 AND 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    Accounts receivable is reflected net  of an allowance for doubtful  accounts
of $766,000 and $2,469,000 at December 31, 1994 and 1995, respectively.
 
STOCK-BASED COMPENSATION
 
    In  October 1995, the  Financial Accounting Standards  Board issued SFAS No.
123, "Accounting for Stock-Based Compensation."  Statement No. 123 is  effective
for  fiscal years  beginning after December  15, 1995. Under  Statement No. 123,
stock-based compensation expense  is measured using  either the intrinsic  value
method, as prescribed by Accounting Principles Board Opinion No. 25, or the fair
value  method described in  Statement No. 123.  Companies choosing the intrinsic
value method will be required to disclose the pro forma impact of the fair value
method on net  income and  earnings per share.  The Company  plans to  implement
Statement No. 123 in 1996 using the intrinsic value method.
 
INCOME TAXES
 
    Two  of the Predecessor Companies elected to  be taxed as S Corporations for
all periods through the respective closing dates of the Acquisitions; therefore,
for federal and state income tax purposes,  any income or loss accrued prior  to
that  date generally was not taxed to  these companies but was reported by their
respective  stockholders.  The  pro  forma  provision  for  taxes  reflects  the
estimated  provision for  federal and state  income taxes which  could have been
provided had these companies been C Corporations and filed consolidated returns.
Because these pro forma income taxes  do not represent obligations of, and  will
not  be paid by, the Predecessor Companies,  they have not been reflected in the
combined balance sheets or in the combined statements of cash flows.
 
PRO FORMA DATA (UNAUDITED)
 
PRO FORMA NET INCOME PER SHARE
 
    Pro forma  net income  per share  will  be calculated  as follows  upon  the
determination  of the  number of  shares of  common stock  to be  offered in the
Company's proposed  initial  public  offering and  the  assumed  initial  public
offering price per share:
 
    Pro  forma net income per  share is based on  the weighted average number of
shares of  common  stock and  common  equivalent shares  outstanding  using  the
treasury  stock method and the estimated number  of shares of common stock to be
issued in the Company's proposed initial public offering whose net proceeds will
be used to redeem  the outstanding preferred stock.  Pursuant to the  Securities
and Exchange Commission requirements, common and common equivalent shares issued
during the 12-month period prior to the initial filing of the Company's proposed
initial  public offering have been  included in the calculation  as if they were
outstanding for all periods presented using the treasury stock method, based  on
the assumed initial public offering price.
 
    The  remainder of the net proceeds from  the sale of        shares of common
stock offered by  the Company in  its proposed initial  public offering will  be
used  to repay certain  indebtedness. Assuming these shares  had been issued and
the indebtedness repaid,  the pro  forma net income  per share  would have  been
$      and $     for the year ended December 31, 1995 and the three months ended
March 31, 1996, respectively.
 
PRO FORMA BALANCE SHEET
 
    As  a  result  of  the  Company's  proposed  initial  public  offering,  all
outstanding  preferred stock, including accrued dividends, will be redeemed. The
pro forma  balance  sheet at  March  31, 1996  reflects  the redemption  of  the
preferred  stock  including accrued  dividends  without the  application  of net
proceeds from such offering. The amounts  were assumed to have been funded  from
the Company's available line of credit at

        (INFORMATION AS OF MARCH 31, 1996 AND FOR THE THREE MONTHS ENDED
                     MARCH 31, 1995 AND 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
March 31, 1996. The pro forma as adjusted balance sheet reflects the anticipated
application of the net proceeds from the sale of       shares of common stock at
an assumed initial public offering price of $      per share.
 
2.  ACQUISITIONS
    During  the year  ended December  31, 1995,  the Company  acquired three new
companies for a total purchase price of approximately $42.8 million. The CRS and
Mascot acquisitions closed on June 1, 1995, and June 9, 1995, respectively,  and
the  King-O-Matic acquisition  closed on  September 12,  1995 (collectively, the
1995 Acquisitions). The Company  issued $40 million of  principal amount of  12%
Senior  Subordinated Notes due  in 2004 concurrent with  the acquisition of CRS,
the proceeds of which financed the  New Acquisitions (Note 6). The  acquisitions
have been accounted for as purchases. Accordingly, the allocation of the cost of
the  acquired assets and liabilities has been made on the basis of the estimated
fair value.
 
    In addition, on  April 2, 1996,  the Company acquired  Tranzparts, Inc.  for
$4.0 million in a transaction accounted for as a purchase.
 
    The  consolidated financial statements include the operating results of each
business from  the  date  of  acquisition. The  following  unaudited  pro  forma
information for the year ended December 31, 1994 reflects the acquisition of the
Predecessor  Companies as  if the acquisition  had occurred on  January 1, 1994,
adjusted to give effect  for federal and  state income taxes  on the results  of
operations had all Predecessor Companies been taxed as a corporation and filed a
consolidated  return,  and gives  effect  to the  1995  acquisitions as  if such
acquisitions  had  occurred  on  January  1,  1994.  The  unaudited  pro   forma
information  for  the year  ended December  31,  1995 gives  effect to  the 1995
Acquisitions and the acquisition of Tranzparts as if such acquisitions  occurred
on  January 1, 1995. The pro forma information includes adjustments for interest
expense that would have  been incurred to  finance the acquisitions,  additional
depreciation  based  on  the fair  market  values  of the  property,  plant, and
equipment  acquired,   and  amortization   of  intangibles   arising  from   the
transactions.  The pro forma financial information is not necessarily indicative
of the results of operations as they  would have been had the transactions  been
effected on the assumed dates.

5.  BANK LINES OF CREDIT
    On July 19, 1994, the Company entered into an agreement with Chemical  Bank,
as  agent,  providing for  a $30  million  revolving credit  facility (Revolving
Credit Facility)  to finance  the  Prior Acquisitions  and for  working  capital
purposes. The funds available to be advanced may not exceed 85% of the Company's
eligible  accounts receivable and 60% of  the Company's eligible inventories, as
defined in the agreement. The available borrowing base at December 31, 1995  was
approximately  $27 million.  All amounts  advanced are  secured by  all accounts
receivable and inventories  and become  due on July  31, 1999.  The Company  may
prepay outstanding advances in whole or in part without incurring any premium or
penalty.
 
    At  the  Company's election,  amounts  advanced under  the  Revolving Credit
Facility will bear interest at either (i)  the Alternate Base Rate plus 1.5%  or
(ii)  the Eurodollar  Rate plus 2.5%.  The Alternate  Base Rate is  equal to the
highest of  (a)  the  Bank's prime  rate,  (b)  the secondary  market  rate  for
three-month  certificates of  deposit plus 1.0%,  or (c) the  federal funds rate
plus 0.5%. Interest  payments on  advances which  bear interest  based upon  the
Alternate  Base  Rate are  due quarterly  in arrears,  and interest  payments on
advances which bear interest based upon the Eurodollar Rate are due on the  last
day  of each relevant interest period (or,  if such period exceeds three months,
quarterly after the first day of such period).
 
    The Company  paid the  Bank  a one-time  facility  and commitment  fee  upon
establishing  the  Revolving Credit  Facility and  is required  to pay  the Bank
quarterly in arrears a  commitment fee of  0.5% per annum  of the average  daily
unused portion of the Revolving Credit Facility.
 
    The  Revolving Credit Agreement contains several covenants, including levels
of net worth, leverage, EBITDA and cash flow coverage, and certain limits on the
Company to incur indebtedness, make  capital expenditures, create liens,  engage
in  mergers and consolidations, make  restricted payments (including dividends),
make asset sales, make investments, issue stock, and engage in transactions with
affiliates of the Company and its subsidiaries. At December 31, 1995, no amounts
were outstanding under this line of credit.
 
    On June 8, 1995, the Company entered  into an agreement with the Royal  Bank
of  Canada  (Royal Bank),  as agent,  providing for  a C$1.35  million revolving
credit facility for working capital  purposes. All amounts advanced are  secured
by  an irrevocable standby letter of credit  from Chemical Bank in the amount of
the U.S.  equivalent of  C$1.35  million. At  December  31, 1995,  $811,067  was
outstanding under this line of

credit.  Amounts advanced under the credit  agreement bear interest at the Royal
Bank prime  rate and  are payable  on the  30th of  each quarter-end  commencing

6.  12% SERIES B AND SERIES D SENIOR SUBORDINATED NOTES
    On  August 2,  1994, the Company  completed a private  placement issuance of
$120 million of principal amount of  12% Series A Senior Subordinated Notes  due
2004.  Proceeds  from  the  issuance,  together  with  the  $40  million capital
contribution, were  used  to finance  the  Initial Acquisitions.  The  privately
placed  debt was exchanged for public debt (designated Series B) on February 22,
1995.
 
    On June 1, 1995, the Company completed another private placement issuance of
$40 million of principal amount of 12% Series C Senior Subordinated Notes due in
2004. Proceeds of $42.4 million from the issuance were used to finance the  1995
Acquisitions.  These  notes  have  an effective  interest  rate  of  10.95%. The
privately placed debt  was exchanged for  public debt (designated  Series D)  on
September 10, 1995.
 
    Interest  on the Notes is payable semiannually on February 1 and August 1 of
each year, commencing on February 1, 1995  for the Series B Notes and August  1,
1995  for the Series  D Notes. The  Notes will mature  on August 1,  2004. On or

    In  addition, at any  time on or prior  to August 1,  1997, the Company may,
subject to certain requirements, redeem up to $30 million of the Series B  Notes
and  $10 million of the Series D Notes  of the aggregate principal amount of the
Notes with the net cash  proceeds of one or more  public equity offerings, at  a
price  equal to  112% of the  principal amount  to be redeemed  plus accrued and
unpaid interest. In  the event  of a  change in  control, the  Company would  be
required  to offer  to repurchase  the Notes  at a  price equal  to 101%  of the
principal amount plus accrued and unpaid interest.
 
    The Notes are general obligations of  the Company, subordinated in right  of
payment  to all existing and future  senior debt (including the Revolving Credit
Facility). The Notes are guaranteed by each of the Company's existing and future
subsidiaries other than any subsidiary designated as an unrestricted  subsidiary
(as   defined).  The  Company  may   incur  additional  indebtedness,  including
borrowings under its $30 million Revolving Credit Facility (Note 5), subject  to
certain limitations.
 
    The  indenture under which the Notes  were issued contains certain covenants
that, among other things, limit  the Company from incurring other  indebtedness,
issuing  disqualified capital  stock, engaging in  transactions with affiliates,
incurring liens,  making  certain  restricted  payments  (including  dividends),
making  certain asset sales, and permitting  certain restrictions on the ability
of its subsidiaries to make distributions. As of December 31, 1995, the  Company
was in compliance with such covenants.

8.  PREFERRED STOCK
    The  Company has  issued 200,000  shares of  nonvoting preferred  stock. The
preferred stock accrues dividends at 10%  per annum and accrues interest at  10%
per  annum  on unpaid  dividends.  Dividends are  payable  annually on  the last
business day in June if  declared by the Board  of Directors. Dividends on  each
share  of the preferred stock are cumulative and accrue from day to day, whether
or not earned or declared, commencing with  the date of issue of such share.  No
dividends have been paid to date.
 
    The  preferred stock is exchangeable at the  option of the Company, in whole
or in part, after July 31,  1996, for Subordinated Exchange Debentures due  July
31,  2006. The Debentures shall  be issued pursuant to  an indenture the form of
which shall have been approved by the  Company and the holders of a majority  of
the outstanding shares of preferred stock.
 
    The  preferred stock may be redeemed at the option of the Board of Directors
at any time,  in whole or  in part, at  a redemption price  equal to the  stated
value  per share, together with  accrued and unpaid dividends  to the date fixed
for such redemption.  Shares of preferred  stock are also  subject to  mandatory
redemption  should substantially  all of  the assets of  the Company  be sold or
transferred, or should  there be a  merger of  Holdings with or  into any  other
corporation  in which  Holdings is not  the surviving  entity. In the  case of a
mandatory redemption, outstanding shares of preferred stock would be redeemed at
a redemption price equal  to the stated value  per share, together with  accrued
and  unpaid  dividends including  accrued interest  to the  date fixed  for such
redemption.
 
    In the event of any liquidation, the preferred stockholders are entitled  to
receive an amount equal to the stated value per share, together with accrued and
unpaid dividends. Thereafter, any remaining proceeds

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)
    Rent expense  under operating  leases approximated  $1,800,000,  $1,159,000,
$902,000,  and $3,114,999 for the year ended December 31, 1993, the seven months
ended July 31, 1994, the five months ended December 31, 1994, and the year ended
December 31, 1995, respectively.
 
    Rent expense  includes  amounts paid  to  related parties  of  $254,000  and
$611,000 for the five months ended December 31, 1994 and the year ended December
31, 1995, respectively.
 
    The  company from  which RPM  acquired its  assets in  1994 (the  "Prior RPM
Company") has  been  identified  by the  EPA  as  one of  the  many  potentially
responsible  parties for environmental liabilities associated with a "Superfund"
site located in the  area of the Company's  former manufacturing facilities  and
current  distribution facility in  Azusa, California. The  EPA has preliminarily
estimated that  it  will  cost  approximately  $47  million  to  construct,  and
approximately  $4  million per  year  for an  indefinite  period to  operate, an
interim remedial groundwater treatment system for the part of the Superfund Site
within  which  the  Company's   former  manufacturing  facilities  and   current
distribution  facility, as well  as those of  many other potentially responsible
parties, are  located.  The actual  cost  of  this remedial  action  could  vary
substantially  from  this estimate,  and  additional costs  associated  with the
Superfund site are likely to be assessed. The Company has significantly  reduced
its  presence at the  site and has moved  all manufacturing operations off-site.
Since July 1995, the Company's only real property interest in this site has been
the lease of  a 6,000  square foot storage  and distribution  facility. The  RPM
acquisition  agreement and the leases pursuant to which the Company leased RPM's
facilities after the RPM Acquisition expressly provide that the Company did  not
assume  any liabilities for  environmental conditions existing  on or before the
RPM Acquisition,  although  the  Company  could  become  responsible  for  these
liabilities under various legal theories. The Company is indemnified against any
such  liabilities  by  the  seller of  RPM  as  well as  the  Prior  RPM Company
shareholders. There can be no assurance, however, that the Company would be able
to make  any  recovery  under  any indemnification  provisions.  Since  the  RPM
Acquisition, the Company has been engaged in negotiations with EPA to settle any
liability that it may have for this site. The Company's management believes that
the  Company  will  not  incur  any material  liability  as  a  result  of these
pre-existing environmental conditions.
 
    In connection  with  the acquisitions  of  Aaron's, RPM,  HTP,  Mamco,  CRS,
King-O-Matic  and Tranzparts,  the Company  conducted certain  investigations of
these companies' facilities and  their compliance with applicable  environmental
laws.  The investigations, which for  all manufacturing and certain distribution
facilities also included "Phase I" assessments by independent consultants, found
that certain remedial,  reporting and other  regulatory requirements,  including
certain  hazardous waste  management procedures, were  not or may  not have been
satisfied. Based in part on the investigations conducted and the indemnification
provisions of  the Prior  Acquisitions' agreements  with respect  to certain  of
these  matters, the Company's management  believes that its liabilities relating
to these environmental matters  will not have a  material adverse effect on  its
future consolidated financial position or results of operations.
 
    The Company is also involved in several lawsuits which arise in the ordinary
course  of business which  management believes will not  have a material adverse
effect,  individually  or  in  the  aggregate,  on  the  Company's  consolidated
financial position or results of operations.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS ACTIVITY
 
    The  Company is a  New Jersey based  remanufacturer of automotive components
for  original  equipment  manufacturers  (OEMs).   It  has  U.S.  and   Canadian
remanufacturing  rights for  designated transmissions, steering  racks and water
pumps produced by certain foreign and domestic OEMs.
 
SIGNIFICANT CUSTOMERS
 
    For the  ten months  ended March  31,  1995, sales  to the  Company's  three
largest  customers,  all  of  whom  are  subsidiaries  of  foreign corporations,
approximated 51%,  15%  and 13%  of  sales.  Additionally, at  March  31,  1995,
accounts receivable from these three customers approximated $1,403,000, $468,000
and $669,000, respectively. Contracts with customers may be terminated by either
party generally upon 30 days notice.
 
    The  Company generally sells to a limited number of OEMs. The Company grants
credit to substantially all of these customers. No credit losses are expected by
management, and no provision  for credit losses are  reflected in the  financial
statements.
 
INVENTORIES
 
    Inventories  are stated at the lower of cost (first-in, first-out method) or
market and  consist  primarily of  new  and used  transmission  parts.  Reserves
consider  deterioration, obsolescence and other  factors in evaluating estimated
net realizable value.
 
EQUIPMENT AND LEASEHOLD IMPROVEMENTS
 
    Equipment and leasehold  improvements are  stated at  cost. Depreciation  is
computed  using accelerated and straight-line  methods over the estimated useful
lives of the assets which range from five to twenty years.
 
CASH AND CASH EQUIVALENTS
 
    Investments with  maturities  of  less  than  90  days  when  purchased  are
considered  the equivalent  of cash. Cash  and cash  equivalents are principally
held by one financial institution.
 
INTANGIBLE ASSETS
 
    The excess of the purchase price over the fair value of the assets purchased
is being amortized over 40 years on a straight-line basis. Cost in excess of net
assets acquired is reflected net of accumulated amortization of $74,965 at March
31, 1995.
 
    Covenants not  to  compete are  being  amortized  over five  years  and  are
presented net of accumulated amortization of $576,566.
 
WARRANTY
 
    The  Company extends warranties  upon installation ranging  from one year or
12,000 miles to two years or 24,000 miles, whichever occurs first. The estimated
cost  under  existing  warranties  has  been  provided  for  in  the   financial
statements.
 
INCOME TAXES
 
    As  of June 1, 1994, the Company elected to be treated as an "S Corporation"
for Federal and State tax purposes under the provisions of the respective taxing
authorities.
 
    The Company provides  for state income  taxes based on  income reported  for
financial reporting purposes.

</TABLE>
 
3.  BANK LINE OF CREDIT AND NOTES PAYABLE
    The  Company has  a $1,200,000  line of credit  which bears  interest at the
prime rate  (9%)  plus  .75% and  is  collateralized  by all  the  tangible  and
intangible property of the Company and is available through December 6, 1995. At
March  31, 1995, the Company  did not have any  outstanding borrowings under the
line of  credit.  The  line  of credit  is  subject  to  compliance  provisions,
including   working  capital   requirements,  other   borrowings,  acquisitions,
redemption of Company stock and dividends. The agreement also provides covenants
as to ownership and management control (See Note 5).
 
    Notes Payable of $151,667  bear interest at 10%  and are payable in  monthly
installments  through December 1995  to the former  majority shareholders of the
Company. Included in that amount is  approximately $68,000 due to the  president
of the Company who currently maintains a minority interest in the Company.
 
4.  COMMITMENTS
    In  July 1994, the  Company relocated its operations  to a new manufacturing
facility. The  facility  is  subleased under  a  five-year  noncancelable  lease
expiring July 12, 1999. There is an option to renew the lease for two additional
five  year  periods at  an  increased monthly  rental.  Rent expense  for leased
facilities for the ten months ended March 31, 1995 was $251,110.
 
    The facility lease also  requires the Company to  pay real estate taxes  and
common area maintenance charges.
 
    The  following  is  a  schedule  of  future  minimum  rental  payments under
operating leases:

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
    Section  145 of the DGCL makes provision for the indemnification of officers
and directors in terms sufficiently broad to indemnify officers and directors of
the  Company   under   certain   circumstances   from   liabilities   (including
reimbursement  for expenses incurred) arising under  the Securities Act of 1933.
The Company's Certificate of Incorporation and Bylaws provide, in effect,  that,
to  the fullest extent and  under the circumstances permitted  by Section 145 of
the DGCL, the  Company will indemnify  any person who  was or is  a party or  is
threatened  to be made a  party to any threatened,  pending or completed action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that he is a director or officer of the Company or is or  was
serving  at  the request  of the  Company as  a director  or officer  of another
corporation or  enterprise.  The  Company  may,  in  its  discretion,  similarly
indemnify  its employees and  agents. The Certificate  of Incorporation relieves
its directors  from monetary  damages to  the Company  or its  stockholders  for
breach  of such  director's fiduciary  duty as  directors to  the fullest extent
permitted by the DGCL.  Under Section 102(b)(7) of  the DGCL, a corporation  may
relieve  its  directors  from  personal liability  to  such  corporation  or its
stockholders for monetary  damages for  any breach  of their  fiduciary duty  as
directors  except (i) for a  breach of the duty of  loyalty, (ii) for failure to
act in good faith, (iii) for intentional misconduct or knowing violation of law,
(iv) for  willful or  negligent  violation of  certain  provisions in  the  DGCL
imposing  certain requirements with respect to stock repurchases, redemption and
dividends, or  (v) for  any  transactions from  which  the director  derived  an
improper personal benefit. Depending upon the character of the proceeding, under
Delaware  law, the Company may  indemnify against expenses (including attorneys'
fees), judgments, fines and amounts  paid in settlement actually and  reasonably
incurred  in  connection  with any  action,  suit  or proceeding  if  the person
indemnified acted in good faith and in a manner he or she reasonably believed to
be in or not opposed to the best  interest of the Company, and, with respect  to
any  criminal action or proceeding,  had no cause to  believe his or her conduct
was unlawful. To the extent that a  director or officer of the Company has  been
successful  in the defense of any action,  suit or proceeding referred to above,
the Company  will  be  obligated  to  indemnify  him  or  her  against  expenses
(including  attorneys'  fees)  actually and  reasonably  incurred  in connection
therewith.
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
    In July 1996, the Company issued 1,000 shares of Common Stock to Holdings in
consideration  of  $13.5  million  in  cash.  The  Company  believes  that  this
transaction  was exempt from  registration under the  Securities Act pursuant to
Section  4(2)  thereof.  Concurrent  with  the  consummation  of  the  Offering,
 
                                      II-1
<PAGE>
Holdings will be merged into the Company, and each outstanding share of Holdings
Common Stock will be converted into   shares of Common Stock of the Company. The
following  is a description  of the issuances of  the unregistered securities of
Holdings.
 
    Holdings sold all 2,000,000 currently outstanding shares of its Common Stock
in July 1994 at the  time of the Initial Acquisitions  at a price of $10.00  per
share  to AEP, AOEP and  certain other investors. There  have been no subsequent
issuances of the Common Stock of Holdings since such time. The Company  believes
that  this transaction was exempt from  registration pursuant to Section 4(2) of
the Act.
 
    In August 1994, Holdings issued options to purchase an aggregate of  216,375
shares  of its Common Stock to seven individuals, including Messrs. Smith, Wehr,
Hester, Kent and Bear. In September 1994, Holdings issued options to purchase an
aggregate of 11,696 shares  to non-affiliates of the  Company. In October  1994,
Holdings  issued  options to  purchase 5,848  shares to  a non-affiliate  of the
Company. In connection with the acquisition of the outstanding capital stock  of
CRS,  Holdings in  June 1995  issued options to  purchase an  aggregate of 6,848
shares of Common Stock to Mr. LePore and another former shareholder of CRS. Also
in June 1995, Holdings issued options  to purchase 5,848 shares of Common  Stock
to a non-affiliate. In August 1995 and November 1995, Holdings issued options to
purchase 1,000 shares to each of Mr. Prugh and a non-affiliate, respectively. In
December 1995, Holdings issued options to purchase 5,848 shares to Mr. LePore.
 
    In  August 1994, Holdings issued warrants to purchase an aggregate of 58,480
shares of its Common Stock  to Mr. Myers and  one other individual. In  December
1994,  Holdings issued warrants to purchase 11,696 shares of its Common Stock to
Dr. Hartnett.
 
    The exercise price for each of the above options and warrants is $10.00, the
same price per share as paid by all purchasers of the Company's Common Stock  at
the time of the Initial Acquisitions. The Company believes that the issuances of
these  options and  warrants were exempt  from registration  pursuant to Section
4(2) of the Securities Act.
 
    On August 2, 1994, the Company completed the sale of $120 million of  Series
A  Notes to Chemical Securities Inc. and Donaldson, Lufkin & Jenrette Securities
Corporation (the  "Initial  Purchasers"). The  Series  A Notes  were  resold  to
Qualified  Institutional Buyers ("QIBs")  and Accredited Institutional Investors
("AII"). The Initial Purchasers resold the Series A Notes to QIBs and AIIs.  The
Company  believes that the  initial placement of the  securities was exempt from
registration under Section 4(2) of  the Act and the resale  of the Notes by  the
Initial Purchasers was exempt from Registration by virtue of Rule 144A under the
Act ("Rule 144A").
 
    On  June 1, 1995, the Company completed the sale of an aggregate $40 million
principal amount  of Series  C  Notes to  the  Initial Purchasers.  The  Initial
Purchasers resold the Series C Notes to QIBs and AIIs. The Company believes that
the  initial  placement of  the securities  was  exempt from  registration under
Section 4(2) of the Act  and the resale of the  Notes by the Initial  Purchasers
was exempt from Registration by virtue of Rule 144A.

ITEM 17.  UNDERTAKINGS.
 
    Insofar as indemnification for liabilities arising out of the Securities Act
of 1933 (the  "Act") may  be permitted  to directors,  officers and  controlling
persons  of the registrant  pursuant to the  foregoing provisions, or otherwise,
the registrant  has been  advised that,  in the  opinion of  the Securities  and
Exchange  Commission, such indemnification is against public policy as expressed
in the Act  and is,  therefore, unenforceable.  In the  event that  a claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
registrant of expenses incurred  or paid by a  director, officer or  controlling
person  of  the registrant  in the  successful  defense in  any action,  suit or
proceeding) is  asserted by  such  director, officer  or controlling  person  in
connection  with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to  a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.
 
    The undersigned registrant hereby undertakes that:
 
        (1) For  purposes  of  determining  any liability  under  the  Act,  the
    information  omitted  from the  form  of prospectus  filed  as part  of this
    registration statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by  the registrant  pursuant to  Rule 424(b)(1)  or (4)  or
    497(h)  under  the Act  shall  be deemed  to  be part  of  this registration
    statement as of the time it was declared effective.
 
        (2) For the  purpose of determining  any liability under  the Act,  each
    post-effective  amendment that contains a form of prospectus shall be deemed
    to be  a  new registration  statement  relating to  the  securities  offered
    therein, and the offering of such securities at that time shall be deemed to
    be the initial BONA FIDE offering thereof.
 
    The  undersigned registrant hereby undertakes to provide to the Underwriters
at the closing specified  in the underwriting  agreements, certificates in  such
denominations  and registered in  such names as required  by the Underwriters to
permit prompt delivery to each purchaser.

                        ON FINANCIAL STATEMENTS SCHEDULE
 
Stockholders and Board of Directors
Aftermarket Technology Corp.
 
    We  have audited the accompanying consolidated balance sheets of Aftermarket
Technology Corp. (the Company) as of December 31, 1994 and 1995 and the  related
consolidated  statements of income, stockholders' equity, and cash flows for the
five months ended December  31, 1994 and  for the year  ended December 31,  1995
(included  elsewhere in this  Registration Statement). We  have also audited the
related combined statements of  income, stockholders' equity  and cash flows  of
the  Predecessor  Companies  to Aftermarket  Technology  Corp.  (the Predecessor
Companies) for the year ended December 31,  1993 and for the seven months  ended
July  31, 1994  (included elsewhere in  this Registration  Statement). Our audit
also included the financial statement schedule as  of and for each of the  three
years  in  the period  ended  December 31,  1995 listed  in  Item 16(b)  of this
Registration Statement. This  schedule is  the responsibility  of the  Company's
management. Our responsibility is to express an opinion based on our audits.
 
    In  our opinion,  the financial statement  schedule referred  to above, when
considered in  relation to  the basic  financial statements  taken as  a  whole,
presents fairly, in all material respects, the information set forth therein.
