                  99       Press Release dated April 30, 2004

Item 12.   Results of Operations and Financial Condition.


         On April 30, 2004, Smithway Motor Xpress Corp. (the "Company") reported
its financial results for its first fiscal quarter ended March 31, 2004. See the
Company's press release dated April 30, 2004, which is furnished as Exhibit 99
hereto. The Company provides net earnings and the related per share amount
excluding the effects of tax-free life insurance proceeds in the press release.
The measures are not in accordance with, or an alternative for, generally
accepted accounting principles and may be different from operational income and
per share measures used by other companies. We believe that the presentation of
net earnings and the related per share amount excluding the one-time effect of
our receipt of life insurance proceeds provides useful information to investors
regarding business trends relating to our financial condition and results of
ongoing operations.
