       Reports 17% Increase In Fiscal 2003 Fourth Quarter Operating Income
                            Over Prior Fourth Quarter

HOLLYWOOD, FL, and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI and HEI.A), today
reported that net income for the fiscal year ended October 31, 2003 was
$12,222,000, or 55 cents per share. For the fiscal year ended October 31, 2002,
net income was $15,226,000, or 68 cents per share. Net income for fiscal 2002
included the recovery of a portion of taxes paid in prior years resulting from
an income tax audit completed in fiscal 2002 and an increase in the gain on sale
of a product line, which increased net income by an aggregate of $2,872,000, or
13 cents per share.

Net sales for fiscal 2003 were up 3% to $176,453,000 from $172,112,000 in fiscal
2002.

For the fourth quarter of fiscal 2003, net income totaled $3,540,000, or 16
cents per share, on sales of $47,662,000. Net income in the fourth quarter of
fiscal 2002 was $5,599,000, or 25 cents per share, on sales of $45,512,000. Net
income in the fourth quarter of fiscal 2002 included the recovery of a portion
of income taxes paid in prior years, which increased net income for the quarter
and full year by $2,107,000, or 9 cents per share, net of related expenses.

Net sales in the fourth quarter of fiscal 2003 represented a 5% increase over
net sales in the fourth quarter of fiscal 2002.

Adjusted on a pro forma basis retroactively for the 10% stock dividend announced
by the Company earlier today, which is to be paid on January 16, 2004, net
income for the fiscal years ended October 31, 2003 and 2002 would be 50 cents
per share and 62 cents per share, respectively, and net income in the fourth
quarters of fiscal 2003 and 2002 would be 14 cents per share and 23 cents per
share, respectively. On a pro forma basis (adjusted for the stock dividend), the
recovered income taxes and additional gain on sale of a product line increased
net income per share (pro forma) by 12 cents in fiscal 2002 and the recovered
income taxes increased net income per share (pro forma) by 9 cents in the fourth
quarter of fiscal 2002.

All per share information referenced above refers to net income per diluted
share.

Cash flow from operating activities for the fiscal year ended October 31, 2003
totaled $27.9 million, equal to approximately 225% of the Company's net income.
This was up $4.6 million from the fiscal year ended October 31, 2002. In the
fourth quarter of fiscal 2003, cash flow from operating activities totaled $9.8
million, up 13% from the fourth quarter of fiscal 2002.

For the fourth quarter of fiscal 2003, operating income was $6,644,000, or 17%
higher than the $5,681,000 reported in the fourth quarter of fiscal 2002.

Operating income increased 4% to $23,205,000 for the fiscal year ended October
31, 2003 from $22,400,000 for the fiscal year ended October 31, 2002. Operating
income for fiscal year 2003 reflects increased sales and earnings within the
Company's Flight Support Group (FSG) attributable to sales of new products and
services and strengthening demand within the commercial aerospace industry. The
higher sales and earnings within the FSG were partially offset by lower sales
and earnings within the Company's Electronic Technologies Group (ETG) for fiscal
2003 due principally to a decline in demand from certain foreign military
customers.

For the fiscal year ended October 31, 2003, the FSG's sales increased 7% to
$128,277,000 from $120,097,000 for the fiscal year ended October 31, 2002. Sales
within the FSG increased 5% to $33,273,000 in the fourth quarter of fiscal 2003
from $31,781,000 in the fourth quarter of fiscal 2002. The increase in revenues
within the FSG for fiscal 2003 and the fourth quarter reflects sales of new
FAA-approved replacement parts, stronger repair and overhaul sales and some
recent recovery within the commercial aerospace industry.

Operating income of the FSG increased 21% to $19,187,000 for the fiscal year
ended October 31, 2003 from $15,846,000 for the fiscal year ended October 31,
2002 and increased 17% to $4,851,000 in the fourth quarter of fiscal 2003 from
$4,163,000 in the fourth quarter of fiscal 2002. The higher sales levels in
fiscal 2003 and the fourth quarter contributed to an improvement in operating
margins and operating income.

Sales and operating income within the ETG were $48,597,000 and $8,497,000,
respectively for the fiscal year ended October 31, 2003 versus $52,510,000 and
$11,873,000, respectively, for the fiscal year ended October 31, 2002. The
decreases for the fiscal year primarily resulted from lower foreign military
sales. In addition, operating margins were somewhat lower in fiscal 2003 due to
a less favorable product mix.

In the fourth quarter of fiscal 2003, sales and operating income of the ETG
improved 5% and 1%, respectively, to $14,495,000 and $3,123,000 as compared to
$13,776,000 and $3,084,000, respectively, in the fourth quarter of fiscal 2002.

Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer,
remarked, "We are pleased to report increased sales and earnings in our Flight
Support Group (FSG) for fiscal 2003, despite the negative impact on the
commercial aviation industry of the military conflict in Iraq and SARs. The
increase in the FSG is primarily due to sales of new products as a result of our
continued investment in new product development, our strategic relationships
with several of the world's major airlines, as well as some improvement in
commercial aviation during the second half of our fiscal year.

                                     -more-



"Our Electronic Technologies Group continued to show improvement in its sales
and earnings in the fourth quarter of fiscal 2003. The fourth quarter sales and
operating income were up 13% and 16% from the third quarter, respectively. The
increase is primarily due to strong product demand during the second half of our
fiscal year and the delivery of some products whose delivery was delayed in the
first half of the year.

"We are also pleased to note that our cash flow from operating activities
remained strong in fiscal 2003, allowing us to reduce our debt by $24 million in
fiscal 2003 and pay our 49th and 50th consecutive semi-annual cash dividends
since 1979.

"As we enter fiscal 2004, we expect continued improvement in our sales and
earnings based on current anticipation of improvement in the economy and our
recent acquisition within the satellite microwave component industry. Based on
current market conditions, we are targeting fiscal 2004 sales and earnings
growth of at least 15% and 30%, respectively, over fiscal 2003 results. The
Company will not be giving guidance on quarterly sales and earnings.

"We remain confident that HEICO's strong financial position, our commitment to
develop new products and services and additional acquisition opportunities will
provide substantial potential for long-term sustainable growth."

Mr. Mendelson added, "The Board's declaration of a 10% stock dividend reported
earlier today in addition to the regular cash dividend reflects its continuing
confidence in HEICO's growth strategies and its policy of rewarding shareholders
with stock dividends/splits in addition to cash dividends. Since 1994, HEICO has
declared three 3-for-2 stock splits and paid six other 10% stock dividends.
Further, by declaring the cash dividend on the shares being issued in the 10%
stock dividend, HEICO's Board has effectively increased the cash portion of the
regular dividend by 10%."

Shareholders are reminded that Common Stock and Class A Common Stock are
identical in all economic respects. The only difference between the shares is
the voting rights. The Common Stock receives 1 vote per share and the Class A
Common Stock receives 1/10 vote per share.

16, 2003 at 8:30 a.m. Eastern Standard Time to discuss its fourth quarter and

Certain statements in this press release constitute forward-looking statements
which may involve risks and uncertainties. HEICO's actual experience may differ
materially from that discussed as a result of factors, including, but not

which could cause lower demand for our goods and services; product specification
costs and requirements, which could cause our costs to complete contracts to
increase; governmental and regulatory demands, export policies and restrictions,
military program funding by U.S. and non-U.S. Government agencies or competition
on military programs, 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 aerospace, defense and electronics
industries, which could negatively impact our costs and revenues. Parties
