FOR IMMEDIATE RELEASE

                     LMI AEROSPACE REPORTS RESULTS FOR 2003

         ST. LOUIS - April 15, 2004 - LMI  Aerospace,  Inc.  (Nasdaq:  LMIA),  a
leading  provider  of  assemblies,  kits and  detail  sheet  metal and  machined
components to the aerospace, defense and technology industries,  announced today
that net sales for the year 2003 were $75.9  million,  a decrease of 6.8 percent
from the year 2002.  For the year ended  December 31,  2003,  LMI reported a net
loss of ($4.0) million or ($0.49) per diluted  share,  compared to a net loss of
($8.3) million or ($1.03) per diluted share 2002.

         Additionally,  LMI  announced  that its  independent  certified  public
accountants,  BDO Seidman,  LLP, has  included an  explanatory  paragraph in its
opinion regarding  uncertainty related to the Company's ability to continue as a
going concern.  This conclusion was based upon the Company's  substantial losses
in  recent  years  and  uncertainty  about  the  Company's  ability  to meet its
financial covenants with its primary lender.

         Sales in the fourth  quarter of 2003 were $18.6  million,  compared  to
$21.9  million  in the  fourth  quarter  of 2002 and $17.6  million in the third
quarter of 2003.  LMI  generated  a net loss of ($1.6)  million  or ($0.20)  per
diluted  share in the fourth  quarter of 2003  compared  to a net loss of ($7.7)
million or ($0.94) per diluted share in the fourth  quarter of 2002.  The fourth
quarter of 2002 included a goodwill impairment charge of $5.1 million.

         During the fourth quarter of 2003, the Company  generated a loss before
income taxes of ($2.6) million,  which was influenced by four significant items:

Expense for obsolete or slow moving inventory in excess of        $ 1.9 million
historical experience
Plant moving expenses in Vista, California                        $ 0.3 million
Restructuring expense in St. Charles, Missouri,                   $ 0.1 million
and Wichita, Kansas
Gain on sale of securities                                        $(0.3) million
                                                                  --------------
Net negative impact on operating loss in the quarter              $ 2.0 million
                                                                  ==============

         A more complete  review of the fourth quarter results for 2003 and 2002
and guidance for 2004 will be released later this week.

         Backlog at December 31, 2003 was approximately $53.9 million, down from
$72.1 million at December 31, 2002.

         "Because  of  operating  difficulties  experienced  by  many of our key
customers in 2003, our emphasis has been on previously  announced cost reduction
efforts at our St. Charles,  Missouri and Wichita,  Kansas facilities as well as
in corporate  overhead costs.  Most of the  restructuring was completed by March
2004 and we are  budgeting  our costs  based on 2004 sales of $75 million to $80
million," said Ronald Saks, President and Chief Executive Officer. "Beginning in
September 2003 our machining and technology  segment  experienced  significantly
higher order rates for both its  military  and laser  products and we now expect
increased  sales volume for this segment in 2004.  In the first quarter of 2004,
our sheet  metal  segment  has begun to  receive  orders for new  components  on
regional,  business and  commercial  aircraft,  the largest  portion of which is
being transferred from another industry supplier. We will modify our budgets and
guidance,  if necessary,  when we are able to  reasonably  estimate the size and
impact of these orders."

         LMI Aerospace,  Inc. is a leading supplier of quality components to the
aerospace and technology  industries.  The Company operates thirteen  facilities
that fabricate,  machine,  finish and integrate formed, close tolerance aluminum
