FOR IMMEDIATE RELEASE


            LMI AEROSPACE REPORTS RESULTS FOR THE FIRST QUARTER, 2004


     ST. LOUIS - May 17, 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  quarter  ended March 31,  2004 were $18.5  million,  a decrease of 11.0
percent  from the quarter  ended March 31,  2003.  LMI reported a net loss after
restructuring  costs of ($1.5)  million or  ($0.19)  per  diluted  share for the
quarter  ended  March 31,  2004,  compared  to a net loss of ($1.0)  million  or
($0.12) per diluted share,  for the quarter ended March 31, 2003.  Restructuring
expenses of $0.5 million were incurred in the first quarter of 2004, compared to
none in the first quarter of 2003.

     Sales for the sheet metal  segment in the first  quarter of 2004 were $14.7
million,  a decrease of 14.1 percent from $17.2  million in the first quarter of
2003.  The  decrease  is due  to  lower  sales  of  business  jet  and  military
components.  Commercial  aircraft  sales of $5.6 million in the first quarter of
2004 were higher than the $5.2 million reported in the first quarter of 2003. As
previously reported,  weakness in demand for business jets in 2003, evidenced by
production  stoppages at several of LMI's customers followed by their aggressive
inventory reduction strategies,  significantly reduced business jet sales in the
first  quarter of 2004 and fiscal 2003.  Backlog for the sheet metal segment was
approximately  $45.2 million at March 31, 2004, down from $51.9 million at March
31,  2003.  Orders for new  components  on  regional,  business  and  commercial
aircraft  received in April,  2004 have  caused the backlog for this  segment to
increase to $50.0 million as of April 30, 2004.

     For the machining  and  technology  segment,  sales in the first quarter of
2004 were $3.8  million,  up from $3.7  million  in the first  quarter  of 2003.
Beginning in September 2003, LMI began to receive significant  reorders of laser
equipment  and  military  components  and orders have  continued  at a high rate
through the first  quarter of 2004.  Backlog for this  segment at March 31, 2004
was  approximately  $14.8  million,  up from $11.7  million  at March 31,  2003.
Backlog at April 30, 2004 is about $16.7 million.

     Gross  profit  for the  Company  for the  first  quarter  of 2004  was $2.7
million, or 14.4 percent of net sales, compared to $2.2 million, or 10.6 percent
of net sales in the first  quarter of 2003.  Gross  profit  for the sheet  metal
segment increased primarily because of cost reduction and restructuring  efforts
during the second  half of 2003 and the first  quarter of 2004 at the  Company's
St.  Charles,  Missouri  and  Wichita,  Kansas  facilities.  Gross profit in the
machining  and  technology  segment  increased  due to  higher  sales and a more
favorable product mix.

     Selling,  general  and  administrative  expenses,  excluding  restructuring
charges of $0.5 million,  for the first quarter of 2004 were $3.2 million,  down
from $3.3 million in 2003.  Budgeted cost  reductions  were offset  primarily by
legal  expenses for preparing a C130 claim and providing  information to satisfy
an  administrative  subpoena filed in February 2004 by the Department of Defense
against Versaform, a wholly-owned subsidiary of the Company.

     Restructuring  charges  during the first quarter of 2004 were $0.5 million.
We continue to expect that these expenses will total $0.9 million.

     The loss  before  income  taxes in the  first  quarter  of 2004 was  ($1.0)
million,  net of  restructuring  charges,  a decline from ($1.5)  million in the
first quarter of 2003. At March 31, 2004, LMI had $9.0 million outstanding under
its $9.7 million revolving line of credit.

     "Our first  quarter 2004  results  fell below our budgeted  targets by $0.5
million",  said  Ronald  S.  Saks,  President  and  CEO of LMI  Aerospace,  Inc.
"However, based on current customer demand and preliminary performance estimates
for the second quarter 2004 to date, we expect to meet our budgeted  targets for
the  second  quarter.  As  previously  announced,  our sales  forecast  for 2004
indicated a $3.0 million  increase in our machining and  technology  segment and
flat sales in our sheet metal segment.  We are modifying our forecast to include
a $4.0  million  increase in our  machining  and  technology  segment and a $1.0
million to $5.0 million increase in our sheet metal segment,  resulting in sales
of $81 million to $85 million in 2004.  We also expect gross  margins to improve
from the 14.4  percent  level in the first  quarter  of 2004 to an average of 18
percent to 20 percent for the full year.  Selling,  general  and  administrative
expense before  restructuring  changes is expected to be about the same as 2003,
given  the  added  legal  costs   associated  with  the  Department  of  Defense
investigation and our claim against a military customer", said Saks.

     "This has been a challenging period for our management and employee group -
our cost reduction and  restructuring  efforts,  together with negotiated  price
increases  on selected  products  and the winding  down of a B-52  refurbishment
program have set the stage for improved performance as we progress through 2004.
Increased  demand from several key  customers,  as well as some  improvement  in
production  rates in the  commercial  aircraft,  regional and business  jet, and
semiconductor  markets  we serve,  will help us resume  the  growth we have been
anticipating  for some time. Our employees are motivated to execute well in this
environment and, barring unforeseen economic disturbances, we believe that these
markets will continue to grow in the next two years. We remain  committed to our
strategy  of  expanding  our market  reach and  improving  our supply  chain and
distribution management so we can better serve our customers needs", said Saks.

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