HOLLYWOOD, FL and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI.A and HEI) today
reported that net income for the fiscal year ended October 31, 2004 increased
69% to $20,630,000, or 80 cents per diluted share, compared to net income of
$12,222,000, or 50 cents per diluted share, for the fiscal year ended October
31, 2003. For the fourth quarter of fiscal 2004, net income increased 46% to
$5,166,000, or 20 cents per diluted share, from $3,540,000, or 14 cents per
diluted share, in the fourth quarter of fiscal 2003.

(NOTE: HEICO has two classes of common stock traded on the NYSE. Both classes,
the Class A Common Stock (HEI.A) and the Common Stock (HEI), are virtually
identical in all economic respects. The only difference between the share
classes is the voting rights. The Class A Common Stock (HEI.A) receives 1/10
vote per share and the Common Stock (HEI) receives one vote per share.)

Operating income increased 41% to $32,619,000 for the fiscal year ended October
31, 2004 from $23,205,000 for the fiscal year ended October 31, 2003 and
increased 51% to $10,004,000 for the fourth quarter of fiscal 2004 from
$6,644,000 for the fourth quarter of fiscal 2003.

Net sales increased 22% to $215,744,000 in the fiscal year ended October 31,
2004 from $176,453,000 in the fiscal year ended October 31, 2003. Net sales for
the fourth quarter of fiscal 2004 were up 28% to $60,980,000 from $47,662,000 in
the fourth quarter of fiscal 2003.

Net income for the fiscal year ended October 31, 2004 includes $4.0 million in
proceeds (net of the minority interest's share of the income) received in the
third quarter from a key-person life insurance policy maintained by a subsidiary
of the Company's Flight Support Group. In the attached Condensed Consolidated
Statements of Operations, the life insurance proceeds are excluded from the
computation of operating income and reported after operating income.

                                    - more -


Included in operating income for the fiscal year ended October 31, 2004 are
$850,000 of pre-tax restructuring expenses within certain subsidiaries of the
Flight Support Group that provide repair and overhaul services and $410,000 of
pre-tax legal and other costs related to litigation brought by a subsidiary of
the Company's Electronic Technologies Group. The net impact of the life
insurance proceeds reduced by the restructuring expenses and litigation-related
expenses increased net income by $3.3 million, or $.13 per diluted share, for
the fiscal year ended October 31, 2004.

Cash flow from operating activities for the fiscal year ended October 31, 2004
increased 58% to $44.1 million, including $5.0 million from the life insurance
proceeds, from $27.9 million in the fiscal year ended October 31, 2003 and
equaled 214% of the Company's net income. Capital expenditures totaled $4.8
million in the fiscal year ended October 31, 2004.

Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer,
remarked, "In reviewing our operating results for fiscal 2004, we are extremely
pleased with the progress we made. Both our Flight Support Group and our
Electronic Technologies Group reported significantly improved sales and
operating income. Our organic sales growth approximated 22% in the fourth
quarter of fiscal 2004 versus the fourth quarter of fiscal 2003 and our PMA
aftermarket sales reached an all time quarterly and yearly high.

Operating margins within our Flight Support Group continued to show
year-over-year improvement despite the restructuring expenses and operating
margins within our Electronic Technologies Group continued at a strong level.
The restructuring efforts within our Flight Support Group, which included
consolidation of two West Coast repair and overhaul facilities, are now
substantially complete.

We are also pleased to note that cash flow continued very strong. Cash flow from
operating activities in the fourth quarter of fiscal 2004 and full year totaled
$11.4 million and $44.1 million, respectively, allowing us to reduce borrowings
under our revolving credit facility by $18.0 million in the fourth quarter.

As we look forward to fiscal 2005 and beyond, we will continue to focus on new
products, further market penetration, additional acquisitions and maintaining
our financial strength. Based on current market conditions, we believe that the
Flight Support Group's operating margins can continue to show year over year
improvement while maintaining the strong operating margins in the Electronic
Technologies Group. Including the results of our recent acquisition,
Connectronics Corp., we are targeting fiscal 2005 net sales growth in the range
of 10% to 13% over fiscal 2004 and fiscal 2005 diluted earnings per share in the
range of $.83 - $.85. This earnings target compares very favorably with the $.80
per diluted share net income reported in fiscal 2004 since the fiscal 2004
results include the $.13 per diluted share net income impact of the life
insurance proceeds reduced by the restructuring and litigation-related expenses.
The Company does not give guidance on quarterly sales or earnings.

Fiscal 2005 cash flow from operating activities should approximate $40 million
and our capital expenditure budget for fiscal 2005 approximates $11 million.

We remain confident our focused business model will provide substantial
potential for sustainable growth."

For the fiscal year ended October 31, 2004, net sales of the Flight Support
Group increased 19% to $153,238,000 from $128,277,000 for the fiscal year ended
October 31, 2003. For the fourth quarter of fiscal 2004, net sales of the Flight
Support Group increased 24% to $41,185,000 from $33,273,000 for the fourth
quarter of fiscal 2003. The increase in net sales for the fiscal year and fourth
quarter ended October 31, 2004 versus the respective fiscal 2003 periods
resulted primarily from improved demand for the Company's replacement parts and
repair and overhaul services, which reflects continuing recovery in the
commercial airline industry, as well as increased sales of new products.
Substantially all of the sales growth of the Flight Support Group in fiscal year
2004 was organic growth.

Operating income of the Flight Support Group increased 26% to $24,251,000 for
the fiscal year ended October 31, 2004 from $19,187,000 for the fiscal year
ended October 31, 2003 and increased 42% to $6,907,000 for the fourth quarter of
fiscal 2004 from $4,851,000 for the fourth quarter of fiscal 2003. The increase
in operating income for the fiscal year and the fourth quarter ended October 31,
2004 reflects the higher net sales resulting from increased sales volumes and
higher margins resulting from improved operating efficiencies within the Flight
Support Group.

Net sales of the Electronic Technologies Group increased 29% to $62,648,000 for
the fiscal year ended October 31, 2004 from $48,597,000 for the fiscal year
ended October 31, 2003 and increased 37% to $19,823,000 for the fourth quarter
of fiscal 2004 from $14,495,000 for the fourth quarter of fiscal 2003. The
increase in net sales for the fiscal year and the fourth quarter ended October
31, 2004 reflects the acquisition of Sierra Microwave Technology in December
2003 and full-year organic sales growth of approximately 6%.

Operating income of the Electronic Technologies Group increased 80% to
$15,259,000 for the fiscal year ended October 31, 2004 from $8,497,000 for the
fiscal year ended October 31, 2003 and increased 81% to $5,644,000 for the
fourth quarter of fiscal 2004 from $3,123,000 for the fourth quarter of fiscal
2003. The increase in operating income for the fiscal year and the fourth
quarter ended October 31, 2004 reflects the acquisition of Sierra and the
organic sales growth.

The 41% increase in total operating income for the fiscal year ended October 31,
2004 and the 51% increase in total operating income for the fourth quarter over
the comparable periods of fiscal 2003 reflect the increased net sales and higher
margins within both the Flight Support Group and the Electronic Technologies
Group.

FOOTNOTES TO CONDENSED CONSOLIDATED STATEMENTS OF OPERATIONS (Unaudited)

- ----------

(1)  Fiscal 2004 operating income was reduced by an aggregate of $850,000 in
     restructuring expenses recorded by certain subsidiaries of the Flight
     Support Group that provide repair and overhaul services including $350,000
     recorded in cost of sales and $500,000 recorded in selling, general and
     administrative expenses. The restructuring expenses decreased fiscal 2004
     net income by $427,000, or $.02 per basic and diluted share. Fiscal 2004
     operating income was also reduced by an aggregate of $410,000 of legal and
     other costs related to litigation brought by a subsidiary of the Electronic
     Technologies Group. The litigation-related expenses decreased fiscal 2004
     net income by $257,000, or $.01 per basic and diluted share.

(2)  Represents proceeds from a $5.0 million key-person life insurance policy
     maintained by a subsidiary of the Flight Support Group. The minority
     interest's share of this income totaled $1.0 million, which is reported as
     a component of minority interests' share of income. Accordingly, the life
     insurance proceeds increased fiscal 2004 net income by $4.0 million, or
     $.17 per basic and $.16 per diluted share.

(3)  Includes employee performance awards expense of $1.4 million in fiscal
     2004, including $1.1 million recorded in the fourth quarter of fiscal 2004.
