"We are extremely pleased to report record quarterly sales and operating income
in our fiscal 2005 second quarter results. Both our Flight Support Group and our
Electronic Technologies Group reported increased sales of 22% and 39%,
respectively, over the second quarter of fiscal 2004. All the sales increase
within the Flight Support Group was organic growth, reflecting the continued
recovery in aftermarket demand within the commercial airline industry, as well
as our continued success in the development of new products and services for our
customers. The sales increase within our Electronic Technologies Group reflects
both strategic acquisitions and organic growth. Organic revenue growth within
the Electronic Technologies Group approximated 9% in the second quarter of
fiscal 2005 when compared to net sales in the second quarter of fiscal 2004.

Operating income of our Flight Support Group increased 48% to $8.9 million for
the second quarter of fiscal 2005 up from $6.0 million for the second quarter of
fiscal 2004 and increased 45% to $16.5 million for the first six months of
fiscal 2005 up from $11.3 million for the first six months of fiscal 2004. The
increase in operating income of the Flight Support Group for the second quarter
of fiscal 2005 and the first six months of fiscal 2005 reflects both the
increase in net sales and higher operating margins resulting principally from
improved operating efficiencies. Operating margins of the Flight Support Group
improved to 19.3% in the second quarter of fiscal 2005 from 15.9% in the second
quarter of fiscal 2004 and improved to 18.6% in the first six months of fiscal
2005 from 15.8% for the first six months of fiscal 2004.

Operating income of our Electronic Technologies Group increased 14% to
$4.2 million for the second quarter of fiscal 2005 up from $3.7 million for the
second quarter of fiscal 2004 and increased 8% to $6.7 million for the first six
months of fiscal 2005 up from $6.2 million for the first six months of fiscal
2004. Operating margins of the Electronic Technologies Group were 20.1% in the
second quarter of fiscal 2005 and 18.7% in the first six months of fiscal 2005,
an improvement over operating margins of 16.7% in the first quarter of fiscal
2005, versus 24.5% in the second quarter of fiscal 2004 and 22.8% for the first
six months of fiscal 2004. Based on the current backlog within our Electronic
Technologies Group, we expect operating margins for the second half of fiscal
2005 to return to a level approximating the operating margins we experienced in
fiscal 2004.

Our consolidated operating margins improved to 17.1% in the second quarter of
fiscal 2005 from 15.5% in the second quarter of fiscal 2004 and 16.2% for the
first six months of fiscal 2005 from 14.9% for the first six months of fiscal
2004.

Cash flow from operating activities for the first half of fiscal 2005 totaled
$11.5 million versus $16.7 million in the first half of fiscal 2004 principally
due to a higher investment in inventories required to meet increased sales
demand and increased accounts receivable due to the higher sales levels. We
continue to target cash flow from operating activities in the range of
$40 million with a net capital expenditure budget of approximately $6 to
$8 million for fiscal 2005.

Based on our strong operating results year to date and current market
conditions, we are raising our target for fiscal 2005 consolidated sales to a
range of $250 to $260 million and diluted net income per share to a range of
$.84 to $.86. The net sales and earnings targets exclude the impact of
additional acquisitions, if any. The earnings target compares very favorably to
the

                                     -more-


$.80 per diluted share reported in fiscal 2004 since the 2004 results included
the net impact of $.13 per diluted share from life insurance proceeds ($.16 per
diluted share) reduced by restructuring expenses ($.02 per diluted share) and
litigation-related expenses ($.01 per diluted share). The Company does not give
guidance on quarterly sales or earnings."

Certain statements in this press release constitute forward-looking statements,
which are subject to risks, uncertainties and contingencies. HEICO's actual
results may differ materially from those expressed in or implied by those
forward-looking statements as a result of factors including, but not limited to:
lower demand for commercial air travel or airline fleet changes, which could
cause lower demand for our goods and services; product specification costs and
requirements, which could cause an increase to our costs to complete contracts;
governmental and regulatory demands, export policies and restrictions,
reductions in defense or space spending by U.S. and/or foreign customers, or
competition from existing and new competitors, which could reduce our sales;
HEICO's ability to introduce new products and product pricing levels, which
could reduce our sales or sales growth; HEICO's ability to make acquisitions and
achieve operating synergies from acquired businesses, customer credit risk,
interest rates and economic conditions within and outside of the aviation,
defense, space and electronics industries, which could negatively impact our
costs and revenues; and HEICO's ability to maintain effective internal controls,
which could adversely affect our business and the market price of our common
stock. Parties receiving this material are encouraged to review all of HEICO's
