FOR IMMEDIATE RELEASE


     LMI AEROSPACE REPORTS RESULTS FOR THE SECOND QUARTER OF 2004

         Revenue gains and cost reductions yield return to profitability


     ST. LOUIS - August 16, 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 second
quarter 2004 net sales were $21.9 million,  an increase of 16.0 percent from the
quarter ended June 30, 2003. LMI reported net income after  restructuring  costs
of $0.1 million or $0.02 per diluted  share for the quarter ended June 30, 2004,
compared to a net loss of ($0.7)  million or ($0.09)  per diluted  share for the
quarter  ended  June 30,  2003.  Restructuring  expenses  of $0.2  million  were
incurred in the second  quarter of 2004,  compared to none in the second quarter
of 2003.

     Sales for the Sheet Metal segment in the second  quarter of 2004 were $17.5
million,  an increase of 9.4 percent from $16.0 million in the second quarter of
2003.  The  increase  was due to higher  sales of business  jet  components.  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. However,  increasing  production rates of
business jets in the second quarter,  2004, as well as a transfer of significant
work statement by Gulfstream to several LMI plants,  resulted in higher business
jet component sales in the current quarter.





     For the Machining and Technology  segment,  net sales in the second quarter
of 2004 were $4.4 million,  up from $2.8 million in the second  quarter of 2003.
This  increase  was  primarily  attributable  to growth  in sales of  technology
products.

     Combined backlog for both segments was $68.4 million at June 30, 2004,
compared to $58.0 million at June 30, 2003.

     Gross  profit  for the  Company  in the  second  quarter  of 2004  was $4.3
million, or 19.7 percent of net sales, compared to $2.4 million, or 12.9 percent
of net sales in the second  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 half of 2004 at the  Company's  St.
Charles,  Missouri, and Wichita,  Kansas,  facilities,  and revenue gains in key
markets.  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 $0.2 million, for the second quarter of 2004 were $3.4 million, up
from $3.2 million in the second quarter of 2003. Budgeted cost reductions were
offset primarily by $0.3 million of legal and consulting expenses related to
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. The Company has forwarded all requested documents to the
Department of Defense for its review.

     The  profit  before  income  taxes in the  second  quarter of 2004 was $0.4
million,  excluding  restructuring  charges,  an increase  from a loss of ($1.2)
million in the second quarter of 2003.

     Sales for the Company for the six months  ended June 30,  2004,  were $40.4
million,  up 1.8 percent from $39.7 million at June 30, 2003. For the first half
of 2004,  the  Company  had a net loss before  incomes  taxes of ($1.3)  million
compared to a loss of ($2.7) million in the first half of 2003.

     "Our operating results for the second quarter of 2004 exceeded our budgeted
targets and brought our year-to-date  results in line with internal  forecasts,"
said Ronald  Saks,  President  and CEO of LMI  Aerospace,  Inc.  "The  operating
results for the second quarter were reduced by costs for  restructuring,  moving
expenses in California,  front-end costs for a new Gulfstream program, and legal
and  consulting  costs  related to the  Department  of Defense  subpoena,  which
totaled  approximately  $0.8  million in the  quarter.  We expect these costs to
abate in the third quarter of 2004, and also anticipate  higher revenue from the
Gulfstream  transfer as that program  volume  ramps up. In addition,  increasing
production  rates in our  commercial  aircraft  and  regional  and  business jet
sectors  have  resulted  in  increased  orders for the balance of 2004 and 2005.
Demand in our military and technology  sectors has been flat of late, and is not
expected to contribute  to the sales growth  expected over the remainder of this
year.  Our  current  forecast  for 2004 is for  sales to be in the  range of $83
million to $87 million,  and gross  margins to average  between 18 to 21 percent
for  the  full  year.  Selling  general  and  administrative   expense,   before
restructuring changes, should be approximately $13.0 million for the year," Saks
said.

     Improvements  in LMI's  operating  performance and the collection of a $1.1
million tax refund allowed the Company to reduce its senior debt by $2.3 million
in the quarter to a balance of $25.6  million at June 30, 2004.  The Company met
its key financial covenants under its lending agreement with its bank as of June
30, 2004. The balance drawn against the Company's $9.7 million  revolving credit
agreement was $8.9 million at August 13, 2004.





     "We are pleased to announce a profit for this quarter.  Although  modest in
amount, it represents a significant  improvement over the last few quarters, and
was  earned  even  though   incurring   significant   other  charges   described
previously,"  Saks said. "Our markets seem to be improving,  and recent gains in
market share give us confidence  that our revenue gains and cost reductions will
combine to help us resume  our growth and  improve  our  operating  results.  We
continue to explore  possible sales of certain assets in order to further reduce
debt levels.  We are committed to our strategy of improving our supply chain and
distribution management,  in order to provide unique services to our customers,"
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
aluminum and specialty alloy components for commercial,  corporate, regional and
military  aircraft,  laser  equipment  used  in the  semiconductor  and  medical
industries, and for the commercial sheet metal industries.

     This  press  release  includes  forward-looking  statements  related to LMI
Aerospace's outlook for 2004, which are based on current management expectation.
Such forward-looking  statements are subject to various risks and uncertainties,
many of which are beyond the control of LMI Aerospace, Inc. Actual results could
