Item 2.    Acquisition or Disposition of Assets

On September 19, 2003, the Company closed the sale (the "Asset Sale") of certain
of the assets of its trailer leasing and rental, and wholesale aftermarket parts
distribution businesses to Aurora Trailer Holdings, LLC ("Aurora"). BB&T Capital
Markets served as the financial advisor to the Company on the asset sale. As a
result of arm's length negotiations and a process involving multiple interested
parties, the Company received approximately $53.3 million in cash. A copy of the
press release announcing the asset divestiture is attached hereto as Exhibit
99.2 and is incorporated herein by reference. The Asset Purchase Agreement, as
amended, which contains the terms of the transaction and the consideration
received, is attached hereto as Exhibit 2.01 and 2.02.

Derek Nagle, the former Senior Vice President of the Company and former
President of its North American Trailer Centers, is an officer of Aurora and we
expect will be involved in the management of the operation of the assets as
acquired by Aurora.

Pro Forma financial information reflecting the estimated effects of the Asset
Sale and the bank financing, described below, and the previously announced
Unsecured Convertible Notes offering (the "Refinancing") are included herein in
Item 7.

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

Item 5.    Other Events and Required FD Disclosure


On September 23, 2003, the Company announced the closing and funding of a new
three year $222 million bank financing package. The Loan and Security Agreement
is attached hereto as Exhibit 10.51. In connection with the Asset Sale and the
Refinancing, the Company incurred approximately $21 million in debt
extinguishment costs and approximately $2 million in asset disposition charges.
A copy of the press release announcing the refinancing is attached hereto as
Exhibit 99.1 and is incorporated herein by reference.

Pro Forma Financial Information

Wabash has prepared the following unaudited pro forma consolidated financial
statements to illustrate the estimated effects of the Asset Sale and the
Refinancing. The Unaudited Pro Forma Consolidated Statements of Operations for
the year ended December 31, 2002 and for the six month period ended June 30,
2003 give effect to the transactions as if they had occurred as of the beginning
of the respective periods. The Unaudited Pro Forma Condensed Consolidated
Balance Sheet gives effect to the transactions as if they had occurred on June
30, 2003. The transactions and the related adjustments are described in the
accompanying notes. The Pro Forma Financial Statements are based upon available
information and certain assumptions that management believes are reasonable. The
Pro Forma Financial Statements do not purport to represent what the Company's
results of operations or financial condition would actually have been had the
transactions in fact occurred on such dates or to project the Company's results
of operations or financial condition for any future period or date. The Pro
Forma Financial Statements should be read in conjunction with the historical
financial statements of the Company and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" contained in the Company Form
10-K for the year ended December 31, 2002 and its Form 10-Q for the quarter
ended June 30, 2003.

          NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS
                       ($ in thousands, except as noted)


(a)  Asset Sale

     On September 19, 2003, the Company completed the sale of certain of the
     assets of its leasing and rental and aftermarket parts businesses for
     approximately $53.3 million in cash. Net proceeds from the sale were used
     to repay a portion of its outstanding indebtedness. Loss on the disposition
     amounted to approximately $29.9 million, including a $28.5 million asset
     impairment charge recorded in the 2003 second quarter. Additionally, the
     Company anticipates a $0.6 million loss on the disposition of retained
     assets. The $1.4 million loss was derived as follows:



                                            
                 Assets sold                   $  53,100

                                               =========



(b)  Refinancing

     On August 1, 2003, the Company completed the sale of $125 million of 3.25%
     five-year senior unsecured convertible notes convertible into shares of the
     Company's stock, subject to market and other conditions. The Company used
     the net proceeds to repay a portion of its outstanding indebtedness. The
     notes have a conversion price of $19.20 or a rate of 52.0833 shares per
     $1,000 principal amount of note. The notes bear interest at 3.25% per annum
     payable semi-annually on February 1 and August 1. Costs associated with the
     transaction amounted to approximately $4.2 million and will be amortized
     over the term of the notes.

     On September 23, 2003, the Company entered into a $222 million three-year
     asset-based loan arrangement that includes a $47 million term loan and a
     $175 million revolver. The new financing will replace existing indebtedness
     and is expected to substantially lower the Company's cost of debt.

     The term loan is secured by Company's property plant and equipment. The
     revolver is secured by inventory and accounts receivable and the amount
     available to borrow varies in relation to the balances of those accounts.

     Interest on the term loan is variable, based on the London Interbank Offer
     Rate (LIBOR) plus 300 basis points, decreasing to 275 basis points after
     six months, or the banks alternative rate as defined in the agreement.
     Interest on the revolver is at LIBOR plus 275 basis points, decreasing to
     250 basis points after six months. The Company pays a commitment fee on the
     unused portion of the facility at a rate of 37.5 basis points per annum.
     Additionally, the Company estimates fee associated with the transaction
     will amount to approximately $3.5 million, which will be amortized over the
     term of the loan.

     The term loan requires quarterly principal payments of $1.7 million
     commencing on January 1, 2004, with the balance due on September 23, 2006.
     The revolver is due on September 23, 2006. Beginning in March 2005, excess
     cash flow, as defined, is required to be used to reduce term loan
     indebtedness.

     The loan agreement contains covenants that require, among other things,
     minimum fixed charge coverage and maximum senior debt to EBITDA coverage.
     Also, the agreement place limits on capital expenditure and additional
     borrowings.

(c)  To record the effects of the refinancing. Interest expense on the
     convertible notes is 3.25%. Interest on the term loan is LIBOR plus 300
     basis points, decreasing to 275 basis points after six months. Interest on
     the revolver is at LIBOR plus 275 basis points, decreasing to 250 basis
     points after six months. Additionally,


                                       6



     interest expense includes an unused facility fee at a rate of 37.5 basis
     points per annum, letter of credit fees and amortization of deferred loan
     costs. The average of the 30 day LIBOR was 1.76% for the year ended
     December 31, 2002 and 1.33% for the six months ended June 30, 2003. The
     effect of a 12.5 basis point change in LIBOR would change interest expense
     approximately $0.2 million and $0.1 million for the year and six month
     periods, respectively.

(d)  To record the write off of the unamortized balance of deferred loan costs
     associated with debt being paid.

(e)  To record the deferred loan costs incurred with the refinancing.

(f)  To record the net effect of the refinancing as follows:



                                                  
              Payment of existing debt               $ 145,465

                                                     =========



(g)  To record the expense associated with the early extinguishment of debt,
     including the write off deferred loan costs, as follows:



                                                   
              Write-off of deferred debt cost         $  8,220
