from $60,980,000 in the fourth quarter of fiscal 2004.

$22,812,000, or 87 cents per diluted share, from $20,630,000, or 80 cents per

(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.)

Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer,
remarked, "We are extremely pleased to report record quarterly net sales and
operating income for the third consecutive quarter. Both our Electronic
Technologies Group and our Flight Support Group

                                    - more -


reported increased net sales of 48% and 15%, respectively, over the fourth
quarter of fiscal 2004. In addition, both groups reported higher net sales for
full fiscal 2005 over fiscal 2004, with the Electronic Technologies Group
reporting a 34% increase and the Flight Support Group reporting a 21% increase.
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 strong results from three strategic
acquisitions made in fiscal 2005 and organic growth of approximately 6%.

Fiscal 2005 consolidated net sales and consolidated operating income represent
record annual results for HEICO.

Operating income of our Flight Support Group increased 45% to $35.1 million for
the fiscal year ended October 31, 2005 from $24.3 million for the fiscal year
ended October 31, 2004. For the fourth quarter of fiscal 2005, operating income
increased 19% to $8.2 million from $6.9 million for the fourth quarter of fiscal
2004. The increase in operating income of the Flight Support Group for the
fiscal year and fourth quarter 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 18.9%
for the fiscal year ended October 31, 2005 from 15.8% for the fiscal year ended
October 31, 2004 and improved to 17.4% in the fourth quarter of fiscal 2005 from
16.8% in the fourth quarter of fiscal 2004.

Operating income of our Electronic Technologies Group increased 22% to $18.6
million for the fiscal year ended October 31, 2005 from $15.3 million for the
fiscal year ended October 31, 2004. For the fourth quarter of fiscal 2005,
operating income increased 44% to $8.1 million from $5.6 million for the fourth
quarter of fiscal 2004. Operating margins of the Electronic Technologies Group
were 22.2% for the fiscal year ended October 31, 2005 and 27.8% in the fourth
quarter of fiscal 2005, down slightly from 24.4% for the fiscal year ended
October 31, 2004 and 28.5% in the fourth quarter of fiscal 2004, due principally
to a less favorable product sales mix.

Our consolidated operating margins improved to 16.6% for the fiscal year ended
October 31, 2005 from 15.1% for the fiscal year ended October 31, 2004 and
improved to 16.7% in the fourth quarter of fiscal 2005 from 16.4% in the fourth
quarter of fiscal 2004.

Cash flow from operating activities for fiscal 2005 continued strong at $35.8
million and compares to $44.1 million in fiscal 2004. The decrease is due to a
higher investment in inventories required to meet increased sales demand and
longer lead times for certain raw materials, as well as increased accounts
receivable due to the higher sales levels.

We recently announced a 60% increase in our semi-annual cash dividend to $.04
per share, which is payable in January 2006. In declaring the cash dividend, our
goal is to reward HEICO shareholders with an increased cash dividend, while
retaining sufficient capital required to fund our internal growth objectives and
acquisition strategies.

As we look to fiscal 2006 and beyond, we believe the increasing product demand
from our customers, our commitment to develop new products and services, our
strong financial position and our ability to identify select acquisition
opportunities provide the foundation for continued growth in sales and earnings.

                                    - more -


Based on current market conditions, we are targeting fiscal 2006 twelve month
net sales growth in the range of 30% to 35% and operating income growth in the
range of 35% to 40% over fiscal 2005 results. We are targeting fiscal 2006
diluted net income per share in the range of $1.05 to $1.09. These targets
include our recent acquisitions, but exclude the impact of additional
acquisitions, if any.

Fiscal 2006 cash flow from operating activities should approximate $42 - $45
million and our capital expenditures budget for fiscal 2006 approximates $12 -
$14 million.

We remain confident our disciplined business model will provide opportunity for
long-term sustainable growth."

22, 2005 at 9:00 a.m. Eastern Standard Time to discuss its fourth quarter and

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,

                                    - more -


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

HEICO CORPORATION
Footnotes to Condensed Consolidated Statements of Operations (Unaudited)

- ----------
(1)  Operating income was reduced in fiscal 2004 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 net income by
     $427,000, or $.02 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)  Fiscal 2005 results reflect increased costs to comply with the
     Sarbanes-Oxley Act of 2002.
