                      WABASH NATIONAL CORPORATION ANNOUNCES
                             SECOND QUARTER RESULTS


         LAFAYETTE, INDIANA, July 22, 2003 . . . Wabash National Corporation
(NYSE: WNC) today announced results for the three and six month periods ended
June 30, 2003. Net sales for the second quarter were $230 million compared to
$210 million for the same period last year. Net loss for the second quarter was
$27 million, including a $29 million non-cash charge related to planned asset
divestitures, compared to a net loss of $22 million for the same period last
year. Diluted loss per share was $1.05 for the quarter, including a $1.09 per
share charge related to planned asset divestitures, compared to a loss of $0.96
per share for the 2002 quarter. For the six months ended June 30, 2003, net
sales were $453 million and a net loss of $26 million, including the $29 million
charge, compared to net sales of $372 million and a net loss of $36 million for
the same period last year. Diluted loss per share for the six months ended June
30, 2003 and 2002 was $1.02, including the $1.09 per share charge, and $1.61,
respectively.


         Commenting on the quarter, William P. Greubel, President and Chief
Executive Officer, stated, "The fundamental changes currently taking place
within the Company could prove to be a watershed period as we move to
structurally improve the Company, both operationally and financially. The
following are just some of the significant highlights from the quarter:


      o   Sales increased 3% from the 2003 first quarter on the continuing
          improvement in demand for new trailers while operating income, before
          the $29 million charge, improved 48% over first quarter 2003 levels.
          We are indeed becoming earnings focused as opposed to share focused.
          We successfully started up two new production lines during the
          quarter, one line for our new Wabash FreightPro sheet and post trailer
          and one line for DuraPlate(R) containers. We believe trailer industry
          demand will continue to improve over the next several quarters. Our
          demand continues to be affected by our large customers managing their
          equipment capacity very closely;


      o   We are in the final planning stages of reorganizing our channels of
          sales and distribution which will allow us to improve our
          opportunities to exploit our product and service offerings in the mid
          to large sized fleet segments of the trailer industry while
          maintaining our strategic relationships with the premier trucking
          companies in the U.S.;


      o   As announced, we have signed a definitive agreement to sell
          substantially all of the assets of our leasing and rental business and
          our aftermarket parts business. Total consideration from the sale of
          these assets and the retained assets is approximately $65-$70 million
          of which $55 million will be paid in cash upon closing. We expect the
          transaction to close in the third quarter and is subject to lender
          approval and buyer financing. As noted above, we recorded an
          impairment









          charge of $29 million in the quarter to recognize the planned disposal
          of these assets at less than book value. This non-cash charge will not
          affect the Company's compliance under its existing bank covenants.
          Upon closing this transaction, all proceeds from this divestiture will
          go toward debt retirement which, including this amount, will total
          approximately $90 million year-to-date;


      o   We also announced the selection of Fleet Capital to lead and fully
          underwrite a new $250 million syndicated bank financing for the
          Company. The new financing, which is subject to Fleet Bank credit
          approval and Wabash board approval, will be a three year asset based
          revolver and term loan that will be used to replace existing
          indebtedness and will substantially lower our cost of debt. Closing on
          the transaction is expected to occur during the third quarter of this
          year. Successfully refinancing our existing debt will result in
          charges of approximately $24 million, including prepayment penalties
          of approximately $20 million and a non-cash charge of approximately $4
          million for the write-off of previously deferred debt costs, which
          will be recognized when the financing is completed. These charges will
          not affect the Company's compliance under its existing bank covenants;
          and


      o   We are in the process of evaluating what we believe will be the final
          piece to our new capital structure, which will mark the culmination of
          two years of work to turn the Company around and to secure its future.


         We continue to meet or exceed our objectives. We have active and sound
management leading our turnaround. Associate involvement has been excellent. Our
capital structure will soon be very solid. We intend to focus our free cash flow
in the future on continuing to pay down debt. We shall augment our profitability
by focusing our products and services on the entire van market going forward. As
the trailer industry improves, we have positioned ourselves to take full
advantage of the recovery."

EBITDA

The company uses EBITDA and Adjusted EBITDA, income (loss) before income taxes,
interest expense, depreciation and amortization; and specific identified charges
in the case of adjusted EBITDA, as an internal measure of performance, and
believes it is useful and commonly used measure of financial performance in
addition to income (loss) before income taxes and other profitability measures
of performance under GAAP. EBITDA should not be construed as an alternative to
operating income and income (loss) before taxes as an indicator of the Company's
operation in accordance with GAAP. Our definition of EBITDA can differ from that
of other companies. The following table reconciles net income, the most
comparable measure under GAAP, to EBITDA and Adjusted EBITDA for the periods
indicated (dollars in millions).
