FOR IMMEDIATE RELEASE


            LMI AEROSPACE REPORTS RESULTS FOR THE SECOND QUARTER 2005
                    Quarterly Revenue and Net Income Increase


         ST. LOUIS - August 10, 2005 - 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 second
quarter 2005 net sales of $24.0 million and net income of $1.0 million or $0.13
per common share compared to net sales of $21.9 million and net income of $0.1
million or $0.02 per common share in the second quarter of 2004.

         The sheet metal segment generated net sales of $20.6 million in the
second quarter of 2005, an 18% increase from $17.5 million in the second quarter
of 2004. The increase was due to higher sales of corporate jet and commercial
aircraft components. For the six months ended June 30, 2005, sales for the sheet
metal segment grew to $41.0 million, a 27% increase from $32.2 million in the
same period of 2004. The majority of the sales growth related to increased sales
of components for use on Gulfstream aircraft, resulting from increased
production rates and additional work statement.

         Net sales for the machining and technology segment fell 23% in the
second quarter of 2005 to $3.4 million from $4.4 million in the second quarter
of 2004. This decrease resulted from a drop in orders for technology products.
Demand for laser products began to improve early in the second half of 2005,
with shipments expected to reach $4.5 million compared to $1.8 million in the
first half of 2005.

         Gross profit for the second quarter of 2005 was $5.6 million or 23.4%,
up from $4.3 million or 19.8% in the second quarter of 2004. The sales gains in
the quarter combined with reduced operating costs resulting from the previous
restructuring at the company's St. Charles, Missouri and Wichita, Kansas
facilities contributed to higher gross profit, as did increased efficiency and
aggressive lean manufacturing initiatives.

         Selling, general and administrative expenses were $3.5 million in the
second quarter of 2005, a decrease from $3.6 million in the second quarter of
2004. For the six months ended June 30, 2005, selling general and administrative
expenses declined to $6.9 million, compared to $7.3 million in the 2004 period.
The six months ended June 30, 2004 included $0.7 million of restructuring
expenses, where as no such changes were recorded in the 2005 period.

         Interest expense for the six months declined to $0.8 million in 2005
from $1.0 million in 2004. Despite increases in interest rates caused by higher
prime lending and LIBOR rates, a combination of debt reduction from operational
cash flow and the lack of a $0.1 million nonrecurring bank charge incurred in
2004 accounted for the decline.


         "Demand for our products and services has continued to increase" said
Ronald Saks, President and CEO of LMI Aerospace, Inc. "The current aerospace
environment of increasing production rates of commercial aircraft and corporate
jets and increased demand on new programs from new and existing customers has
caused our backlog to reach an all time high on June 30, 2005 of $99 million.
Awards during the second quarter of 2005 for assemblies and components for
Sikorsky Blackhawk helicopters from both Vought and Sikorsky, as well as a more
recent transfer of Boeing 777 work from another supplier, have added to our
production demands in 2005 and 2006. In addition, we expect our machining and
technology segment to generate increased sales in the second half of 2005."

         "Consistent with our current guidance, our forecast for 2005 is for
sales of $100 to $105 million, gross margins of 22 to 24 percent, selling,
general and administrative expense of $14.5 million, interest expense of $1.8
million, and a tax rate of 37 to 38 percent, before any tax credits. Our
forecast for 2006 sales has been raised to $110 million to $125 million, based
on existing contracts with our customers, increased production rates, and newly
awarded business," Saks commented.

         Saks continued, "We project that increasing demand for our products and
services will continue through 2006. The reduced capacity of the domestic supply
base will require that we expand organically, both within and outside the United
States, through use of direct investment, joint ventures, and independent
suppliers."
