                HEICO CORPORATION REPORTS SECOND QUARTER RESULTS

HOLLYWOOD, FL, and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI and HEI.A), today
reported net income of $2,608,000, or 12 cents per share, for the second quarter
of fiscal 2003 on sales of $41,591,000. For the second quarter of fiscal 2002,
net income was $3,970,000, or 18 cents per share, on sales of $43,001,000. Net
income in the second quarter of fiscal 2002 included $765,000, or 3 cents per
share, from the after tax gain on the sale of a product line.

For the first six months of fiscal 2003, net income totaled $5,442,000, or 25
cents per share, on sales of $83,379,000. Net income for the first half of
fiscal 2002 was $6,798,000, or 30 cents per share, including the $765,000, or 3
cents per share, after tax gain on the sale of the product line, on sales of
$84,013,000.

Cash flow from operating activities totaled $13.5 million for the first six
months of fiscal 2003, up $3.2 million from the first half of fiscal 2002, and
equaled approximately 250% of the Company's net income in the first half of
fiscal 2003.

Operating income was $4,931,000 in the second quarter of fiscal 2003 versus
$6,003,000 in the second quarter of fiscal 2002. For the first six months of
fiscal 2003, operating income totaled $10,460,000 versus $11,765,000 in the
first half of fiscal 2002. Operating income in the second quarter and the first
six months of fiscal 2003 reflects lower sales and earnings within the Company's
Electronic Technologies Group (ETG), partially offset by increased sales and
earnings within the Company's Flight Support Group (FSG) and lower corporate
expenses.

Sales within the FSG increased 3% to $30,376,000 in the second quarter of fiscal
2003 from $29,538,000 in the second quarter of fiscal 2002 reflecting increased
revenues related to sales of new products and services. For the first six months
of fiscal 2003, FSG sales increased 6% to $62,262,000 from $58,592,000 in the
first six months of fiscal 2002, which is also primarily attributable to new
products and services.

Operating income of the FSG in the second quarter of fiscal 2003 increased 8% to
$4,162,000 from $3,840,000 in the second quarter of fiscal 2002 and increased
18% to $9,539,000 in the first six months of fiscal 2003 from $8,106,000 in the
first six months of fiscal 2002. These increases primarily reflect higher sales
and lower new product development expenses.

                                     -more-



Sales and operating income within the ETG were $11,288,000 and $1,904,000,
respectively, in the second quarter of fiscal 2003 versus $13,630,000 and
$3,431,000, respectively, in the second quarter of fiscal 2002. For the first
six months of fiscal 2003, sales and operating income within the ETG were
$21,288,000 and $2,672,000, respectively, versus $25,764,000 and $6,091,000 in
the first six months of fiscal 2002. These decreases primarily resulted from
lower foreign military sales, delays in shipments resulting from production
delays in certain products as well as some delays pursuant to customer
requirements.

ETG sales and operating income for the second quarter were up 13% and 148%,
respectively, compared to the first quarter of fiscal 2003, reflecting delivery
of some of the previously delayed products.

Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer,
remarked, "We are pleased to report improved earnings in our Flight Support
Group, despite the continued weakness in the world economy and commercial
aerospace industry, which has been further impacted by the military conflict in
Iraq and the outbreak of SARS. The improved earnings in the Flight Support Group
are a result of our new product development efforts and our strategic
relationships with some of the world's major airlines. We believe that this
increase validates HEICO's well-known strategy of constantly focusing on medium
to long-term growth opportunities. In addition, we have continued to expand our
services to the regional airlines through a small acquisition earlier this
month.

"ETG sales for the first six months of 2003 were lower than the same period of
2002; however, sales and operating income for the second quarter of 2003 were up
$1.3 million and $1.1 million, respectively, compared to the first quarter of
2003. This increase reflects the shipments of some of the products that were
delayed in the first quarter, although the timing of certain foreign military
sales remains uncertain.

"We are also pleased to note that our cash flow from operating activities
remained strong in the first six months of fiscal 2003, allowing us to
successfully replace our $120 million revolving credit facility earlier this
month and to reduce outstanding borrowings on the facility by $8 million since
our last fiscal year end and by $20 million over the past twelve months.

"Although we remain confident of our long-term opportunities for growth, we have
revised our target fiscal 2003 earnings to a range of 50 to 55 cents per share
on sales growth of 1% to 2% over our fiscal 2002 sales due to the current
uncertainty in the commercial aviation industry. Despite challenges in the
aviation industry, HEICO remains committed to growth through its new product
development programs. Our new parts and repair services continue to lower the
operating costs of our worldwide customers, and have become integral to their
cost reduction and survival strategies. Further, our partnerships with
Lufthansa, American Airlines, United Airlines, Delta Air Lines, and Air Canada
give us a committed customer base on which we can plan our growth and unit
volumes."

                                     -more-
