                                  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 the  United States and Canada, 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. According  to the Automotive
Parts & Accessories Association, 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 ("ACP") 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  five  additional
acquisitions completed during  1995 and  1996. The Company  and its  predecessor
companies  have achieved  compound annual growth  in revenue of  38.5% from 1992
through September 30, 1996 (29.7% if the Company's acquisitions in 1995 and  the
first  nine months of 1996 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.
 
                                       4
<PAGE>
    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.
 
HISTORY; REORGANIZATION
 
    ATC  and Holdings,  its sole stockholder  prior to  the Reorganization, 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  and  Diverco,   Inc.  ("Diverco")  in   October  1996  (the   "1996
Acquisitions"   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, 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 one share  of
ATC Common Stock, and each outstanding share of Holdings Redeemable Exchangeable
Cumulative  Preferred Stock (the  "Holdings Preferred Stock")  will be converted
into one share of  ATC Redeemable Exchangeable  Cumulative Preferred Stock  (the
"ATC  Preferred Stock"),  which will immediately  thereafter be  redeemed for an
amount in cash  equal to $100.00  plus an amount  in cash equal  to accrued  and
unpaid   dividends  on  the  Holdings  Preferred   Stock  to  the  date  of  the
Reorganization (the  "Preferred  Stock  Reorganization  Consideration").  As  of
December  31, 1996,  the aggregate Preferred  Stock Reorganization Consideration
would  be  approximately  $25.2  million  (including  $5.2  million  of  accrued
dividends).  As of October 31, 1996,  12,000,000 shares of Holdings Common Stock
and 200,000 shares of  Holdings Preferred Stock were  outstanding, all of  which
were  issued  in  July and  August  of 1994  when  the Company  was  formed. See
"Reorganization and GEPT Private Placement."  Certain officers and directors  of
the Company own Holdings Preferred Stock and will therefore receive a portion of
the  Preferred  Stock  Reorganization Consideration.  See  "Ownership  of Voting
Securities" and "Certain Transactions."
 
    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.
 
CONTROL OF THE COMPANY
 
    Prior to  this Offering,  approximately  92% of  the voting  power  (through
direct  ownership of shares and the grant of irrevocable proxies) and 72% of the
common equity in the Company are held by Aurora Equity Partners L.P. and  Aurora
Overseas  Equity Partners I, L.P. (collectively, the "Aurora Partnerships"). The
general partner of each of the  Aurora Partnerships is indirectly controlled  by
Messrs.  Richard R.  Crowell, Richard  K. Roeder  and Gerald  L. Parsky. Messrs.
Crowell and Roeder are also directors of the Company. Upon consummation of  this
Offering  and  the  GEPT Private  Placement,  the  Company will  continue  to be
controlled by the Aurora Partnerships, which will hold approximately 73% of  the
voting power (through direct ownership and the grant of irrevocable proxies) and
50%  of the common  equity in the Company.  See "Risk Factors  -- Control of the
Company; Anti-Takeover Matters," "Ownership  of Voting Securities" and  "Certain

    These results  do not  reflect the  taxes that  would have  been payable  by
    certain   of  the  Predecessor  Companies  if  they  had  been  taxed  as  C
    Corporations rather than S Corporations during the period. In addition,  the
    results  do not  reflect the  following adjustments  related to  the Initial
    Acquisitions: (i) the interest expense and amortization of related financing
    costs incurred  in  connection  with  the  Initial  Acquisitions;  (ii)  the
    amortization  of  the  goodwill  created  in  connection  with  the  Initial
    Acquisitions; and (iii)  the adjustment  of compensation  expense to  levels
    provided  in new  employment agreements following  the Initial Acquisitions.
    Accordingly, the 1993 combined results are  not presented on the same  basis

<PAGE>
                                  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 $72.7  million of  the
Company's  combined net sales for the year  ended December 31, 1995 and the nine
months ended September 30, 1996, respectively, or approximately 35.4% and 36.5%,
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 1995 the Company established a  central core return center for all  of
Chrysler's  transmission product lines.  The operation of  this facility enables
the Company to  receive cores  on a  more timely  basis and  better monitor  the
availability  of cores.  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.
 
    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  in the event that such  acquisitions
are  made at levels  that exceed the  fair market value  of net tangible 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 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
 
                                       9
<PAGE>
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
$165.0  million at  September 30, 1996,  bearing interest at  a weighted average
rate of 11.7%, and the Company's ratio of earnings to fixed charges for the nine
months then ended was 2.3 to 1. After giving effect to the consummation of  this
Offering,  the GEPT Private Placement,  borrowings under the Company's revolving
credit facility  and the  application of  the estimated  net proceeds  therefrom
(after  deducting  the  underwriting  discount and  estimated  expenses  of this
Offering), the consolidated long-term indebtedness  of the Company at  September
30,  1996 would have been $136.6 million  and the Company's ratio of earnings to
fixed charges  for the  nine months  then ended  would have  been 2.8  to 1.  On
October  1, 1996, the  Company borrowed $6.9 million  under its revolving credit
facility  to  purchase  Diverco.  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  and  Stephen  J.  Perkins, President  and  Chief  Executive  Officer. Mr.
Perkins, Mr.  Smith,  Wesley N.  Dearbaugh,  President and  General  Manager  of
Independent  Aftermarket, and the presidents  of the operating subsidiaries have
an average  of  21 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 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
 
                                       10
<PAGE>
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, Tranzparts  and
Diverco. 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 this
Offering and  the  GEPT Private  Placement,  the  Company will  continue  to  be
controlled  by the Aurora Partnerships, which will hold approximately 73% of the
voting power  in  the  Company  (through  direct  ownership  and  the  grant  of
irrevocable  proxies). Therefore, the Aurora Partnerships  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 the Aurora
Partnerships' 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
the Aurora Partnerships or their  participation in the transaction. The  general
partner  of each  of the Aurora  Partnerships is controlled  by Messrs. Crowell,
Roeder and Parsky. Messrs. Crowell and Roeder 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 5,000,000  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 this Offering and the  GEPT Private Placement, the Company  will
have  approximately  16,455,794 shares  of  Common Stock  outstanding,  of which
approximately 12,955,794  shares  will  be "restricted  securities"  within  the
meaning  of Rule 144 ("Rule 144") promulgated  under the Securities Act of 1933,
as amended (the
 
                                       11
<PAGE>
"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  stockholders  (including GEPT)  and  certain holders  of  the Company's
outstanding options have  been granted certain  "piggyback" registration  rights
and  certain "demand" registration  rights with respect to  the shares of Common
Stock owned  by them  or  to be  issued to  them.  However, subject  to  certain
exceptions, 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 (including GEPT), 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 this Offering and
the GEPT  Private  Placement  options and  warrants  to  purchase  approximately
2,693,274  shares of Common Stock at exercise prices ranging from $1.67 to $4.67
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 this
Offering, there has been  no public market for  the Common Stock.  Consequently,
the  initial  public offering  price  has been  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 this 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 this
Offering.
 
                                       12
<PAGE>
                              RECENT DEVELOPMENTS
 
    On  October 1,  1996 the  Company acquired  Diverco, Inc.,  a distributor of
standard drive  train parts  (primarily  gears, transfer  cases,  synchronizers,
bearings),  engine parts (valve train components),  gaskets and other soft parts
for transmission and engine repair  and complete transmissions for light  trucks
and  automobiles for aftermarket customers. On the acquisition closing date, the
Company made an initial  cash payment of $8.5  million, with a potential  future
post-closing purchase price adjustment to be made based upon Diverco's financial
performance  for  the  year  ending  December  31,  1996.  Diverco's  sales have
increased from $6.7 million for the year ended December 31, 1993 to $7.3 million
for the 12 months ended August 31, 1996. Diverco is located in Harvey, Illinois.
 
    The  Company  periodically  evaluates   acquisition  opportunities  in   the
automotive  aftermarket business and expects to continue to do so in the future.
The Company has entered  into a non-binding letter  of intent for another  North
American  drive train  parts distributor.  The letter  of intent  provides for a
purchase  price  of  approximately  $10  million  and  is  subject  to   certain
contingencies,  including  the  Company's satisfactory  completion  of business,
legal, accounting  and  environmental  due  diligence  reviews,  negotiation  of
definitive  agreements,  and  approval  of the  respective  transactions  by the
Company's Board of Directors. The letter of intent does not obligate either  the
Company  or  the  potential acquisition  candidate  to enter  into  a definitive
agreement, and there can be no assurance given that the Company will enter  into
a definitive acquisition agreement or consummate such acquisition.
 
                   REORGANIZATION AND GEPT PRIVATE PLACEMENT
 
    Simultaneous with the consummation of this Offering, Holdings will be merged
into  ATC.  Upon the  effectiveness of  such merger,  each outstanding  share of
Holdings Common Stock will be converted into  one share of ATC Common Stock  and
each  outstanding share of  Holdings Preferred Stock will  be converted into one
share of ATC Preferred Stock, which will immediately thereafter be redeemed  for
the  Preferred Stock Reorganization  Consideration. As of  December 31, 1996 the
aggregate Preferred Stock  Reorganization Consideration  would be  approximately
$25.2  million (including  $5.2 million of  accrued dividends as  of such date).
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  December 13, 1996,
Holdings amended  and restated  its charter  to increase  its authorized  Common
Stock to 30,000,000 shares and consummated a six-for-one stock split.
 
    The Company will sell to GEPT $12.0 million of Common Stock (955,794 shares)
in  the GEPT Private Placement simultaneously with the closing of this Offering.
The price per share for  such Common Stock will be  the price per share paid  by
the  Underwriters in this Offering ($12.555), that is, the public offering price
per share  less  Underwriters' discounts  and  commissions. Although  GEPT  will
receive  Common Stock which has not been registered under the Securities Act, it
will also receive a "demand"  registration right and a "piggyback"  registration
right with respect to such stock and 300,000 shares of Common Stock it currently
owns,  which  rights are  not exercisable  until  after the  end of  the 180-day
"lock-up" period described  in "Underwriters." See  "Shares Eligible for  Future
Sale."  The GEPT Private Placement is  conditioned on consummation of an initial
public offering by the Company.

<PAGE>
                                USE OF PROCEEDS
 
    The net  proceeds to  the Company  from  the sale  of the  3,500,000  shares
offered  hereby are estimated  to be approximately  $43.2 million (approximately
$49.8 million if the Underwriters'  over-allotment option is exercised in  full)
after  deducting  estimated underwriting  discounts  and offering  expenses. The
proceeds to the Company  from the GEPT Private  Placement will be  approximately
$12 million.
 
    The  net proceeds  of this Offering  will be  used by the  Company to retire
$40,000,000 in aggregate principal  amount of the  Company's Senior Notes.  Such
Senior Notes may be retired pursuant to provisions thereof permitting redemption
out  of the net  proceeds of certain  sales of equity  securities or pursuant to
repurchases in the open market. Redemption  would be made at a redemption  price
of  112% plus accrued interest thereon  (assuming a December 31, 1996 redemption
date) and after  the giving of  at least 30  days' prior written  notice to  the
holders  of the  Senior Notes  to be  redeemed. Any  remaining proceeds  of this
Offering (including  from  any  exercise  of  the  Underwriters'  over-allotment
option),  together  with  the  proceeds  from  the  GEPT  Private  Placement and
borrowings under the Company's  revolving credit facility, will  be used by  the
Company  to  pay  the  aggregate  Preferred  Stock  Reorganization Consideration
(approximately $25.2 million, assuming a December 31, 1996 Reorganization date).
 
    Pending application  of  the net  proceeds  of this  Offering  as  described
herein,  the  Company  intends  to  invest  the  proceeds  in  investment-grade,
short-term, interest-bearing securities.
 
                                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.

    The following  table  sets  forth the  consolidated  capitalization  of  the
Company  at September 30, 1996, and as  adjusted to give effect to the estimated

the  receipt  of  $12.0  million  from  the  GEPT  Private  Placement,  and  the
application  thereof  and of  borrowings  under the  Company's  revolving credit
facility as described  under "Use  of Proceeds." This  table should  be read  in

(1)  The Company had  approximately $26 million available  under its $30 million
    revolving credit facility as of September 30, 1996. On October 1, 1996,  the
    Company  borrowed  $6.9  million  under  the  revolving  credit  facility to
    purchase Diverco.
 
(2) Consists of Holdings Preferred Stock. See "Recapitalization."
 
(3) Does not give effect  to the issuance of  shares reserved for issuance  upon

(4)  The 12% Senior Notes are assumed to be retired at their 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
    September 30,  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 September 30,
1996 was ($99.4)  million, or ($8.28)  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 September 30, 1996, other than to
give effect to the sale of the  3,500,000 shares of Common Stock at the  initial
public  offering price of $13.50  per share, the GEPT  Private Placement and the
anticipated application of the  net proceeds therefrom,  pro forma net  tangible
book value of the Company as of September 30, 1996 would have been approximately
($47.6) million, or ($2.89) per share (after giving effect to the use of the net
proceeds  from this Offering and the GEPT Private Placement). This represents an
immediate increase in net tangible book value of $5.39 per share to current  ATC
stockholders  and an immediate dilution of $16.39 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.
 
(3) See Note 1 of Notes to Consolidated Financial Statements for description  of
    the  computation of pro  forma net income  per share. Giving  effect to this
    Offering,  the  GEPT  Private  Placement,  borrowings  under  the  Company's
    revolving  credit facility  and the application  of such funds  as set forth
    under "Use of Proceeds" as if the same had occurred on January 1, 1995,  pro
    forma net income per share would have been $0.67 for the year ended December
    31,  1995, and assuming  such transactions had occurred  on January 1, 1996,
    pro forma net income  per share would  have been $0.77  for the nine  months
    ended September 30, 1996.
 
(4)  Excludes capital  expenditures made by  each of  CRS, Mascot, King-O-Matic,
    Tranzparts and Diverco 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 $4,746 at December
    31, 1994 and 1995 and September 30, 1996, respectively.

    The Unaudited Pro Forma Consolidated Statements of Income for the year ended
December 31, 1995 and for the nine  months ended September 30, 1996 assume  that
the  1995 Acquisitions and the 1996 Acquisitions occurred on January 1, 1995 and
the 1996 Acquisitions occurred on  January 1, 1996, respectively. The  Unaudited
Pro Forma Statements of Income include the historical consolidated statements of
income   of  the  Company  (which  includes   the  operations  of  CRS,  Mascot,
King-O-Matic and Tranzparts  from the dates  of their respective  acquisitions),
adjusted  for  the pro  forma effects  of  the 1995  and 1996  Acquisitions. The
Unaudited Pro Forma Consolidated Statements of Income, as adjusted, for the year
ended December  31, 1995  and for  the  nine months  ended September  30,  1996,
reflect  this  Offering,  the  GEPT  Private  Placement,  borrowings  under  the
Company's revolving credit  facility and the  application of such  funds as  set
forth  under "Use of Proceeds,"  as if the same had  occurred on January 1, 1995
and January 1, 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  the 1995 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  and  Diverco for  the  year ended  December  31, 1995.  The 1996
    amounts include Tranzparts  for the  three months  ended April  2, 1996  and
    Diverco for the nine months ended September 30, 1996.
 
(2)  As  adjusted to  give  effect to  the  anticipated application  of  the net
    proceeds from this Offering, the GEPT Private Placement and borrowings under
    the Company's revolving credit facility as if such transactions had occurred
    at the  beginning of  the respective  periods. Amounts  do not  reflect  the
    impact  of the early  retirement 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 retirement. As of September 30, 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  owners 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 depreciation expense for the acquired companies from the
    beginning of the period through the respective acquisition dates.
 
(8) Reflects additional amortization expense for the acquired companies from the
    beginning of the period through the respective acquisition date.
 
(9) 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.
 
(10) Eliminates  interest on  the Senior  Notes that  are assumed  to have  been
    retired.
 
(11) Eliminates interest on debt not assumed in the acquisitions.
 
(12)  Reflects  interest  on  borrowings under  the  Company's  revolving credit
    facility. See "Use of Proceeds."
 
(13) 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.
 
(14)  Reflects  additional  income  taxes  resulting  from  the  adjustments for
    interest expense.
 
(15)  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 38.5% from 1992 through September 30, 1996 (29.7% if
the 1995 and 1996 Acquisitions are excluded).
 
    The  Company's  revenues  from sales  to  Independent  Aftermarket customers
increased by 55.6% from  $58.5 million to $91.0  million between 1992 and  1995.
This growth was due to geographic expansion through the 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 zero in 1992 to $14.4 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 constant 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.
The Company is a  party to negotiations involving  the potential acquisition  by
the  Company  of a  North American  distributor of  drive train  components. See
"Recent Developments."
 
    In the fourth quarter of 1996, the Company will record a non-cash charge  of
approximately  $477,000  for  deferred  compensation  expense  relating  to  the
difference between  the exercise  price and  the intrinsic  value for  financial
statement  presentation  purposes  of  the Company's  Common  Stock  for 628,176
options granted in October 1996. Substantially all of such options were  granted
to  Mr. Perkins and other members of  senior management at $4.67 per share. This
compensation expense will aggregate  $2.3 million, and  will be recognized  over
the  respective vesting periods of the options, which generally range from three
to five years.
 
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
 
                                       21
<PAGE>
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.

</TABLE>
 
    NINE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO NINE MONTHS ENDED SEPTEMBER
30, 1995
 
    NET SALES.  Total  net sales increased $66.8  million or 50.4%, from  $132.5
million for the nine month period ended September 30, 1995 to $199.3 million for
the  nine month period ended September 30, 1996. Of this increase, $39.0 million
was due to  internal growth and  $27.8 million  was due to  the incremental  net
sales  generated  by the  companies acquired  in 1995  and 1996,  including CRS,
Mascot, King-O-Matic and Tranzparts which were  acquired on June 1, June 9,  and
September 12, 1995, and April 2, 1996, respectively.
 
    The  internal growth  was generated  primarily from  increased sales volumes
with existing  OEM customers.  To  a lesser  extent,  internal growth  was  also
generated  by the  incremental sales from  five new  distribution centers opened
during the  second  half  of  1995, increased  sales  volumes  through  existing
distributions   centers  and  increased  sales   volumes  with  existing  retail
customers.
 
    Net sales  to Chrysler  of $72.7  million for  the nine  month period  ended
September  30, 1996 represented 36.5%  of the Company's total  net sales for the
period, as compared to $46.1 million and  34.8% for the nine month period  ended
September  30, 1995.  Management believes, although  there can  be no assurance,
that  the  Chrysler  inventory  reduction  discussed  below  in  the  net  sales
comparison  between 1995 and 1994 was a  one-time effort to reverse an inventory
build-up in 1994 and is not expected to recur.
 
    GROSS PROFIT.   Gross profit  as a percentage  of net  sales increased  from
38.0%  for the nine month period ended September  30, 1995 to 38.5% for the nine
month period ended September 30, 1996.  The increase in gross profit margin  was
primarily attributable to a shift in product mix, lower direct labor cost, and a
higher  absorption  of overhead  resulting from  increased production  and sales
volumes of  remanufactured  transmissions.  The  gross  profit  margin  improved
despite  certain non-recurring start-up costs incurred during 1996 in connection
with the Company's new plant in  Joplin, Missouri and the expansion of  capacity
at  the Company's plant in Springfield,  Missouri needed to support sales growth
to retail and OEM customers.
 
    SELLING, GENERAL AND ADMINISTRATIVE EXPENSES.  As a result of an increase in
revenues, SG&A decreased as a  percentage of net sales  from 19.9% for the  nine
month  period ended September 30, 1995 to  19.4% for the nine month period ended
September 30,  1996. However,  SG&A  increased in  absolute dollars  from  $26.4
million  for the nine month period ended September 30, 1995 to $38.7 million for
the nine month  period ended  September 30,  1996, representing  an increase  of
$12.3  million or  46.6%. The increase  in SG&A  was due largely  to the ongoing
incremental SG&A expenses  of CRS,  Mascot, King-O-Matic  and Tranzparts.  Other
significant  factors contributing  to the increase  in SG&A  include the ongoing
incremental expenses associated  with the five  new distribution centers  opened
during  the second half of 1995, and  certain start-up and ongoing SG&A expenses
incurred in connection with the Company's new plant in Joplin, Missouri.

<PAGE>
    AMORTIZATION OF  INTANGIBLE  ASSETS.    Amortization  of  intangible  assets
increased  $0.4 million for  the nine month  period ended September  30, 1996 as
compared to  the nine  month  period ended  September  30, 1995  reflecting  the
increase  in intangible assets that occurred as  a result of the acquisitions of
CRS, Mascot, King-O-Matic and Tranzparts.
 
    INCOME FROM OPERATIONS.   Principally as a result  of the factors  described
above,  income from operations  increased 63.9% from $21.6  million for the nine
month period ended September 30, 1995 to $35.4 million for the nine month period
ended September 30, 1996.
 
    INTEREST EXPENSE (INCOME),  NET.   Interest expense  increased $2.1  million
from  $13.0 million for the nine month  period ended September 30, 1995 to $15.1
million for the  nine month  period ended September  30, 1996.  The increase  in
interest  expense was due to the interest on  the Series D Notes which were used
to finance the  acquisitions of CRS,  Mascot and King-O-Matic,  and the  related
amortization  of debt issuance costs. The Series  D Notes were issued on June 1,
1995 and therefore were only outstanding  for four months during the nine  month
period ended September 30, 1995.
 
    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  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.

<PAGE>
    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  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 $(0.3) 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 $40.0  million, and,  to a  lesser
extent, through cash provided by operating activities.
 
    The  Company had total cash and cash  equivalents on hand of $8.3 million at
September 30, 1996, representing a decrease in net cash of $0.4 million for  the
nine  months then  ended. Net  cash provided  by operating  activities was $10.8
million in 1995. Net cash provided by operating activities was $7.4 million  for
the  nine months ended September 30, 1996. Net cash used in investing activities
was $45.4 million  and $10.0  million for  1995 and  for the  nine months  ended
September  30, 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 used  in investing activities was  $10.0 million for the
nine months ended September 30, 1996, including $4.1 million for the acquisition
of Tranzparts and $5.9 million in capital expenditures largely for  transmission
and  engine  remanufacturing equipment  and  other improvements  related  to the
Company's new  plant  in  Joplin,  Missouri.  Net  cash  provided  by  financing
activities  was $34.0 million in 1995, due  principally to the issuance of $42.4
million of
 
                                       24
<PAGE>
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 $2.1 million during the nine months ended September 30,
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 September  30,
1996,  the Company had incurred  $5.9 million and had  placed purchase orders of
$2.2 million for additional equipment and leasehold improvements.
 
    The Company has a  $30.0 million revolving credit  facility that matures  in
July  1999. As of September 30, 1996,  the Company had approximately $26 million
available under the revolving credit facility.  On October 1, 1996, the  Company
borrowed  $6.9 million under the revolving  credit facility to purchase Diverco.
The Company has entered  into a non-binding letter  of intent for another  North
American  drive train  parts distributor.  The letter  of intent  provides for a
purchase price  of approximately  $10 million,  which would  be drawn  from  the
revolving  credit facility if the  transaction is consummated. Upon consummation
of this Offering and the GEPT  Private Placement, the Company expects to  borrow
approximately $17 million under its revolving credit facility to pay the balance
of the Preferred Stock Reorganization Consideration. See "Use of Proceeds."
 
    In  July 1996, the Company  entered into an agreement  with Bank of Montreal
("BOM") for a $3.0 million Canadian revolving credit facility to accommodate the
working capital needs of the  Company's Canadian subsidiaries, King-O-Matic  and
Mascot.  Borrowings under  the agreement  are limited  to certain  advance rates
based upon the eligible  accounts receivable and  inventory of King-O-Matic  and
Mascot  up to an aggregate maximum of $3.0 million Canadian, are due upon demand
and bear  interest at  the BOM  prime  lending rate  plus 0.25%.  The  agreement
contains   certain  covenants  including  a  tangible  net  worth  covenant  for
King-O-Matic and Mascot combined, and the terms of the agreement are subject  to
annual review.
 
    The  Company  believes that  cash  on hand,  cash  flow from  operations and
existing borrowing capacity will be  sufficient to fund its ongoing  operations,
including  amounts that  the Company estimates  would be  expended in connection
with  the  potential  acquisition  discussed  under  "Recent  Developments."  In
pursuing additional future acquisitions, the Company expects to have to consider
the  effect any such  acquisition costs may  have on its  liquidity. In order to
consummate such acquisitions, the Company may accordingly need to seek to  raise
additional  capital  through  additional borrowings  or  equity  financings. The
information  in  this  paragraph  is  forward-looking  and  involves  risks  and
uncertainties  that could significantly impact  the Company's expected liquidity
requirements in the short and long term.  While it is impossible to itemize  the
many factors and specific events that could affect the Company's outlook for its
liquidity  requirements, such  factors would  include the  possible reduction in
deliveries to one or more significant customers for any reason and the  possible
effect  of assimilating acquisitions into  the Company's existing operations and
the expansion of those operations.
 
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  five  additional
acquisitions  completed during  1995 and 1996.  The Company  and its predecessor
companies have achieved  compound annual growth  in revenue of  38.5% from  1992
through  September 30, 1996 (29.7% if the Company's acquisitions in 1995 and the
first nine months of 1996 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 the  United States and Canada, 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. According  to the Automotive
Parts & Accessories Association, 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,  refurbished 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.

    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 and light duty truck transmissions and air compressors.
 
    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
 
                                       27
<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, TRANZPARTS and DIVERCO 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, TRANZPARTS  and DIVERCO  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 and O'Reilly  Auto Parts, 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
 
                                       28
<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
believes  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, INTERCONT
and DIVERCO brand  names are  well recognized  and respected  in their  regional
markets.  Sales to Independent Aftermarket customers  accounted for 47.7% of the
Company's revenues in 1995 and 41.5% in the first nine months 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 50.7% of revenues in  the
first  nine months of 1996.  Sales to Chrysler accounted  for 35.4% and 36.5% of
the  Company's  revenues  in  1995  and  in  the  first  nine  months  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
 
                                       29
<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, the  Company recently  established a  central core
return center for all of  Chrysler's transmission models. 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.  The  Company  is currently
working with Chrysler  to improve the  tracking and management  of cores,  which
will  allow the Company 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 $72.7 million for the  first nine months 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 (595 retail locations in 29 states),
O'Reilly Auto Parts (188 retail locations in four states) and Advance Auto  (535
retail  locations in nine states). Sales  to retail automotive parts stores have
grown from virtually zero in 1991 to $14.4 million in 1995 and $15.6 million  in
the first nine months 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
 
                                       30
<PAGE>
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.
 
    INTERNAL GROWTH -- INDEPENDENT AFTERMARKET
 
    INCREASING  SALES  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 repair market, presents a growth
opportunity.   Currently,  the  vast  majority   of  post-warranty  repairs  are
 
                                       31
<PAGE>
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.
 
    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.
 
    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 Advance Auto as customers.
 
    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.  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
 
                                       32
<PAGE>
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
and  Diverco  in 1996.  The Company  is  a party  to negotiations  involving the
potential acquisition by the  Company of a North  American distributor of  drive
train components. See "Recent Developments."
 
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  refurbished.  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.

<PAGE>
    The  Company  believes  that   its  current  manufacturing  facilities   and
distribution  centers  are  adequate  for the  current  level  of  the Company's
activities. The Company's  transmission and engine  remanufacturing facility  in
Springfield, Missouri is currently employing two work shifts, seven days a week.
Other manufacturing sites have the flexibility to add both additional shifts and
production  workers  needed to  accommodate additional  demand for  products and
services. However,  in the  event  the Company  were  to experience  a  material
increase  in sales, the Company may require additional manufacturing facilities.
The Company  believes such  additional  facilities are  readily available  on  a
timely  basis on  commercially reasonable  terms. Further,  the Company believes
that the  leased  space  housing its  existing  manufacturing  and  distribution
facilities is not unique and could be readily replaced, if necessary, at the end
of  the terms of its  existing leases on commercially  reasonable terms. Many of
the Company's leases are renewable at the option of 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.  The EPA has informally estimated that these costs may be in excess of
$1 million. Further, if  the EPA determines that  the interim remedial  measures
are  not adequate, additional  costs could be incurred.  As discussed above, the
"responsible parties" for this site could be held liable for these EPA costs. In
addition to cleanup costs,  the responsible parties may  be required to pay  for
damages  for injuries to natural resources such as soil, groundwater or wildlife
caused by  the contamination  at  the BPOU.  To  date, the  government  agencies
authorized  to claim natural  resource damages for  this site have  not made any
assessment of the value, if any, of such damages. 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
 
                                       35
<PAGE>
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 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,
Tranzparts   and   Diverco   acquisitions,   the   Company   conducted   certain
investigations  of  these  companies'  facilities  and  their  compliance   with
applicable environmental laws and is presently conducting similar investigations
with  respect  to one  other  potential acquisition.  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 September 30, 1996,  the Company employed approximately 3,075  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.

    1994 STOCK INCENTIVE PLAN
 
    The  1994 Stock Incentive Plan was adopted in order to provide incentives to
employees and  directors of  the Company  by granting  them awards  tied to  the
Company's  Common Stock. In February 1995,  the Stock Incentive Plan was amended
to  include  non-employee  directors  and  independent  contractors.  The  Stock
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 October  31, 1996,  the Company  has granted  options to  purchase an
aggregate of up to 2,272,218 shares of Common Stock to officers and employees of
the Company. The exercise  price for these options  to purchase an aggregate  of
1,526,778  shares is $1.67 per share and $4.67 per share for options to purchase
an aggregate  of 745,440  shares.  Each option  is  subject to  certain  vesting
provisions. All options expire on the tenth anniversary of the date of grant. As
of  the  same date,  the number  of  shares available  for issuance  pursuant to
options  granted  under  the  Stock  Incentive  Plan  is  127,782.  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.
 
RELATIONSHIP WITH ACP
 
    Fees of approximately $1.1 million were  paid to ACP for investment  banking
services  provided  in  connection  with the  acquisitions  of  Mascot,  CRS and
King-O-Matic in 1995 and  Tranzparts and Diverco in  1996. The Company has  also
agreed  to pay to ACP a base annual management fee of approximately $530,000 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, King-O-Matic, Tranzparts and Diverco. The base annual management fee  is
also  subject  to  increase  for  specified cost  of  living  increases.  If the
Company's EBITDA 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 or the  GEPT Private Placement), 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  80% of the original base
annual  management  fee  (as  such  original  base  annual  management  fee  may
previously  have been  adjusted due to  discretionary increases by  the Board of
Directors or cost of living increases  as described above, the "Original  Fee");
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  60% of the  Original Fee; 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 40% of the
Original Fee. 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."
 
    In October 1996,  the Company  granted options  for an  aggregate of  48,000
shares  to certain directors and consultants of the Company who are employees of
ACP, including Messrs. Hardy and Larsen.
 
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
 
                                       45
<PAGE>
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 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.
 
PAYMENT OF PREFERRED STOCK REORGANIZATION CONSIDERATION
 
    Upon  the  effectiveness of  the Reorganization,  each outstanding  share of
Holdings Common Stock will be converted into  one share of ATC Common Stock  and
each  outstanding share of  Holdings Preferred Stock will  be converted into one
share of ATC Preferred Stock, which will immediately thereafter be redeemed  for
the  Preferred Stock  Reorganization Consideration, 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 on the  Holdings Preferred Stock to the date  of
the Reorganization.
 
    In  connection with the  formation of the  Company, in July  and August 1994
Holdings issued Holdings Preferred  Stock to each  purchaser of Holdings  Common
Stock  for consideration  of $100  per share,  totaling an  aggregate of 200,000
outstanding shares.  As of  December  31, 1996,  the aggregate  Preferred  Stock
Reorganization  Consideration  would  be  approximately  $25  million (including
approximately $5 million of accrued and unpaid dividends). Messrs. Smith,  Wehr,
Crowell,  Hardy, Larsen and Roeder (each of  whom is a director and/or executive
officer of the Company) hold the  following shares of Holdings Preferred  Stock,
respectively:  563;  11,250;  1,624; 109;  187;  and  243. Such  shares  will be
converted into  the  right  to  receive  the  following  respective  amounts  in
Preferred  Stock  Reorganization Consideration:  $70,375;  $1,406,250; $203,000;
$13,625; $23,375;  and $30,375.  AEP and  AOEP originally  purchased 95,392  and
15,233 shares of Holdings Preferred Stock, respectively, which were subsequently
distributed to their general and limited partners.
 
REGISTRATION RIGHTS
 
    The  holders of the Company's Common  Stock outstanding before this Offering
have been granted certain "demand" and "piggyback" registration rights  pursuant
to  a Stockholders Agreement. In addition, GEPT will be granted certain "demand"
and "piggyback" registration  rights with  respect to 300,000  shares of  Common
Stock owned by GEPT and the shares to be sold in the GEPT Private Placement. See
"Shares Eligible for Future Sale."
 
                          DESCRIPTION OF CAPITAL STOCK
 
    Giving  effect to  the Reorganization, the  authorized capital  stock of ATC
consists of 30,000,000 shares  of Common Stock, par  value $0.01 per share,  and
5,000,000  shares  of Preferred  Stock, par  value  $0.01 per  share ("Preferred
Stock"). As of October 31, 1996,  12,000,000 shares of Common Stock were  issued
and  outstanding and were held of record by 37 stockholders and 2,693,274 shares
were reserved for  issuance under outstanding  options and warrants.  As of  the
same  date after  giving effect  to the  Reorganization, 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
    In  connection with the Reorganization, ATC will issue 200,000 shares of the
ATC Preferred Stock which  will be redeemed by  ATC immediately thereafter.  See
"Reorganization  and GEPT  Private Placement."  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 350,880 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 70,176  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 $1.67 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
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 350,880  of the warrants  and the  number of shares  issuable upon  the
exercise  thereof will be adjusted accordingly; the other 70,176 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 this 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.
 
TRANSFER AGENT AND REGISTRAR
    The  transfer  agent  and  registrar  for  the  Company's  Common  Stock  is
ChaseMellon Shareholder Services.
 
                      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
and instruments to  which each summary  relates. Copies of  such agreements  and
instruments  have been filed as exhibits  to the Registration Statement of which
this Prospectus is a part.
 
BANK LINES OF CREDIT
    In July 1994, the Company entered into a Revolving Credit Agreement with The
Chase Manhattan Bank (formerly  known as 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
 
                                       48
<PAGE>
letters of  credit may  be issued,  in each  case up  to an  aggregate of  $30.0
million and up to $10.0 million with respect to any individual letter of credit,
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  1.25%,
or  (ii) the Eurodollar Rate  plus 2.25%. 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.
 
    In  July 1996,  the Company entered  into a Revolving  Credit Agreement with
Bank of  Montreal (the  "BOM Revolving  Credit Agreement")  for a  $3.0  million
Canadian  revolving credit facility to accommodate  the working capital needs of
the Company's Canadian  subsidiaries. Subject to  the satisfaction of  customary
conditions,  advances under the BOM Revolving  Credit Agreement may be made, and
letters of credit may be issued, in each case up to an aggregate of $3.0 million
Canadian, due upon demand, and subject to annual review. The funds available  to
be  advanced  may not  exceed  the aggregate  of  75% of  the  eligible accounts
receivable of  Mascot and  King-O-Matic and  50% of  the eligible  inventory  of
Mascot  and King-O-Matic  in each  case as defined  in the  BOM Revolving Credit
Agreement. The amounts advanced  under the BOM  Revolving Credit Agreement  bear
interest  at the Bank of  Montreal prime lending rate  plus 0.25%. The agreement
contains certain convenants  including a  tangible net worth  convenant for  the
combined results of Mascot and King-O-Matic.
 
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 indentures by and among  ATC, each of ATC's subsidiaries and
Firstar Bank  of Minnesota,  N.A. (formerly  known as  American Bank  N.A.),  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
 
                                       49
<PAGE>
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.
 
    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 this 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,
Anti-Takeover Matters."

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of this Offering and the GEPT Private Placement, the Company
will have  approximately  16,455,794 shares  of  Common Stock  outstanding.  The
3,500,000  shares sold in  this Offering (4,025,000  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  12,000,000 shares of Common Stock  outstanding immediately prior to the
consummation of this Offering and  the shares to be  issued in the GEPT  Private
Placement  were or will  be 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  (approximately 164,558  shares immediately
after this  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.
 
    In addition, the Commission has published  a notice of proposed rule  making
which,  if adopted  as proposed,  would shorten  the applicable  holding periods
under Rule 144(d) and Rule 144(k) to  one and two years, respectively (from  the
current periods of two and three years). The Company cannot predict whether such
amendments  will be adopted or the effect  thereof on the trading market for its
Common Stock.
 
    The Company currently has outstanding  warrants to purchase an aggregate  of
421,056  shares  of  Common Stock  and  employee  stock options  to  purchase an
aggregate of 2,272,218  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  (including  GEPT), 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  September 30, 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
(which have been waived  with respect to this  Offering) and in connection  with
certain secondary public offerings effected by the Company.
 
    The  Stockholders Agreement has  been amended to provide  that if, after the
Aurora Partnerships distribute  their shares  of Common Stock  to their  limited
partners,  any such limited partner holds 10%  or more of the outstanding Common
Stock, such limited partner (the "Demand Holder") will have the right to require
the Company to use its best efforts  to file a registration statement under  the
Securities  Act  covering  the  resale  of  the  Demand  Holder's  shares  in an
underwritten offering. If following such offering the Demand Holder still  holds
10%  or more of  the outstanding Common  Stock, the Demand  Holder will have one
additional "demand" registration right.
 
    The Company will  bear all  expenses incident to  any registration  effected
pursuant  to the  Stockholders Agreement, 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.
 
    In connection with  the GEPT  Private Placement,  the Company  will grant  a
"demand"  registration right  to GEPT.  Such registration  right will  cover the
shares being issued in the GEPT Private  Placement as well as 300,000 shares  of
Common Stock owned by GEPT prior to the GEPT Private Placement. Pursuant to this
 
                                       51
<PAGE>
registration  right,  GEPT  may,  subject to  certain  limitations,  require the
Company to  use its  best efforts  to file  a registration  statement under  the
Securities  Act covering the resale of such shares of Common Stock. In addition,
GEPT will be granted a "piggyback" registration right to include such shares  on
a  pro rata  basis in any  registration effected  for the account  of any person
exercising a contractual "demand" registration  right granted by the Company  in
the  future.  All fees,  costs  and expenses  of  such registration  (other than
underwriting discounts and commissions) will be  borne by the Company. GEPT  and
any underwriters through whom shares are sold on behalf of GEPT will be entitled
to  customary  indemnification  from the  Company  against  certain liabilities,
including liabilities under the Securities  Act. GEPT's registration rights  may
not  be exercised until after the end  of the 180-day "lock-up" period described
below and may not be exercised  after the third anniversary of the  consummation
of this Offering.
 
    The Company will agree with the Underwriters, subject to certain exceptions,
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
(including GEPT), 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  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.
 
    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.

    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 $.575 per share under the public offering price. Any
Underwriter may allow, and such dealers may re-allow, a concession not in excess
of $.10 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 525,000  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
 
                                       54
<PAGE>
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,  other than stock or stock  option issuances by the Company pursuant
to existing employee benefit plans. Each of the Company's current  stockholders,
directors, executive officers and warrant holders will enter into or is bound by
a similar agreement.
 
    At  the request of the Company, the Underwriters have reserved up to 175,000
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.

Common Stock  of  the  Company.  The initial  public  offering  price  has  been

periods,  and the  price-earnings ratios,  price-sales ratios,  market prices of
securities and certain financial and operating information of companies  engaged

               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.

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 September  30, 1996  and for  the nine months
ended September 30,  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
nine  months  ended September  30, 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.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
      (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with original maturities
of three months or less to be cash equivalents.
 
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.
 
CONCENTRATION OF CREDIT RISK
 
    Financial  instruments that potentially subject the Company to a significant
concentration of credit risk consist of accounts receivable from its  customers,
which are primarily in the automotive aftermarket industry

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
      (INFORMATION AS OF SEPTEMBER 30, 1996 AND FOR THE NINE MONTHS ENDED
                   SEPTEMBER 30, 1995 AND 1996 IS UNAUDITED)
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
throughout  the United  States and Canada.  The credit risk  associated with the
Company's accounts receivable  is mitigated  by its  credit evaluation  process,
reasonably  short collection terms and, except for one significant customer, the
geographical dispersion of sales transactions.
 
    The Company  grants credit  to certain  customers who  meet  pre-established
credit  requirements. Customers who do not  meet those requirements are required
to pay  for  products upon  delivery.  Credit losses  are  provided for  in  the
financial   statements   and   consistently   have   been   within  management's
expectations.
 
    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.
 
WARRANTY POLICY
 
    The Company generally provides a warranty on its products for a period of up
to twelve months or 12,000 miles.
 
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 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 including accrued dividends.
Pursuant to  the Securities  and Exchange  Commission requirements,  common  and
common  equivalent shares issued during the  12-month period prior to the 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.
 
    Historical earnings  per  share is  not  considered meaningful  due  to  the
significant  changes in the Company's capital structure that will occur upon the
closing of the Company's  initial public offering;  accordingly, such per  share
information is not presented.

1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
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 September 30,  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 September 30, 1996.
 
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). In addition, on
April 2, 1996,  the Company acquired  Tranzparts, Inc. for  $4.0 million and  on
October  1, 1996 the Company acquired Diverco, Inc. ("Diverco") for $8.5 million
for the 1996  Acquisitions. All  such 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.
 
    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 1996  Acquisitions as  if  such acquisitions  occurred on
January 1, 1995. The unaudited pro  forma information for the nine-months  ended
September  30,  1996  gives  effect  as if  such  Acquisitions  occurred  at the
beginning of 1996. 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.

Upon  completion of the  Prior Acquisitions, the Company  entered into three- to
five-year lease agreements on most of the properties which had been leased  from
related parties to the Predecessor Companies.
 
    The  Company had liabilities to  former stockholders totaling $4,989,867 and
$36,734 at December 31, 1994 and 1995, respectively. These amounts are  composed
primarily   of  an   additional  purchase   price  payable   to  Aaron's  former
stockholders. The  remaining amount  will  be paid  upon collection  of  certain
accounts receivable in 1996.

5.  BANK LINES OF CREDIT
 
CURRENT LIABILITIES
 
    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 September  30,  1995.  The rate  in  effect at
December 31, 1995 was 7.5%.
 
REVOLVING CREDIT FACILITY
 
    On July  19, 1994,  the Company  entered into  an agreement  with The  Chase
Manhattan  Bank (formerly known as 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.

5.  BANK LINES OF CREDIT (CONTINUED)
    At the  Company's  election, amounts  advanced  under the  Revolving  Credit
Facility  will bear interest at either (i) the Alternate Base Rate plus 1.25% or
(ii) the Eurodollar Rate  plus 2.25%. 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 Facility  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.
 
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

6.  12% SERIES B AND SERIES D SENIOR SUBORDINATED NOTES (CONTINUED)
    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.

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

    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

10. COMMITMENTS AND CONTINGENCIES (CONTINUED)
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.
 
11. FAIR VALUE OF FINANCIAL INSTRUMENTS
    The carrying amounts  of all  financial instruments  approximate their  fair
values  at December  31, 1994  and 1995, except  for the  Series B  and Series D
subordinated debt.
 
    The fair values of the Company's Series B and Series D subordinated debt are
estimated using discounted cash  flow analyses, based  on the Company's  current
incremental borrowing rates for similar types of borrowing arrangements.
 
    The  carrying  amounts and  fair values  of  these financial  instruments at
December 31 are as follows:

the  five months ended December 31, 1994,  and the year ended December 31, 1995,
sales to  one customer  accounted  for 34%,  43%, 45%,  and  35% of  net  sales,
respectively.  Additionally,  at  December  31,  1994  and  1995,  this customer
accounted for approximately 71% and 46% of accounts receivable, respectively. No
other customer accounted for more than 10% of net sales in any period.
 
13. SUBSEQUENT EVENTS
    In June 1996, the Company's  Board of Directors approved the  reorganization
of  the Company in which  Holdings will be merged  into ATC. This reorganization
will be effected simultaneous with the  closing of the Company's initial  public
offering (see Note 1).
 
    On  December 13,  1996, a six  for one  stock split of  the Company's common
stock and an increase in the number of authorized shares to 30,000,000 shares of
common  stock  and  5,000,000  shares  of  preferred  stock  was  effected.  The
accompanying  financial statements  have been retroactively  adjusted to reflect
the stock split.

                         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:
