                           HEICO REPORTS SIGNIFICANTLY
                            IMPROVED 2ND QTR RESULTS
          58% Increase In Net Income & 66% Increase in Operating Income
            On 27% Increase in Net Sales; Continued Strong Cash Flow

HOLLYWOOD, FL and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI.A and HEI) today
reported that net income for the second quarter of 2004 increased 58% to
$4,108,000, or 16 cents per diluted share, compared to net income of $2,608,000,
or 11 cents per diluted share, for the second quarter of fiscal 2003.

Net sales for the second quarter of fiscal 2004 were up 27% to $52,793,000 from
$41,591,000 in the second quarter of fiscal 2003.

For the first six months of fiscal 2004, net income increased 35% to $7,349,000,
or 29 cents per diluted share, from $5,442,000, or 22 cents per diluted share,
in the first six months of fiscal 2003. Net sales increased 19% to $98,944,000
in the first six months of fiscal 2004 from $83,379,000 in the first six months
of fiscal 2003.

Cash flow from operating activities for the first half of fiscal 2004 increased
24% to $16.7 million from $13.5 million in the first six months of fiscal 2003
and equaled 228% of the Company's net income. Capital expenditures totaled $2.2
million in the first half of fiscal 2004.

All per share and share information has been adjusted retroactively to give
effect to a 10% stock dividend paid in January 2004.

Operating income increased 66% to $8,172,000 for the second quarter of fiscal
2004 from $4,931,000 for the second quarter of fiscal 2003 and increased 41% to
$14,745,000 for the first six months of fiscal 2004 from $10,460,000 for the
first six months of fiscal 2003. The increase in operating income for the second
quarter and the first six months of fiscal 2004 reflects increased sales and
higher margins within each of the Company's two operating segments, the Flight
Support Group (FSG) and the Electronic Technologies Group (ETG).

For the second quarter of fiscal 2004, sales of the FSG increased 24% to $37,710,000 from $30,376,000 for the second quarter of fiscal 2003. For the first six months of fiscal 2004, FSG sales increased 16% to $71,967,000 from $62,262,000 for the first six months of fiscal 2003. The increase in revenues for the second quarter and first six months of fiscal 2004 resulted primarily from improved demand for the Company's replacement parts and repair and overhaul services, which reflects continuing recovery in aftermarket demand from the commercial airline industry, as well as increased sales of new products. Operating income of the FSG increased 44% to $6,012,000 for the second quarter of fiscal 2004 from $4,162,000 for the second quarter of fiscal 2003 and increased 19% to $11,338,000 for the first six months of fiscal 2004 from $9,539,000 for the first six months of fiscal 2003. The increase in operating income for the second quarter and first six months of fiscal 2004 reflects the higher sales and improved margins within the FSG. Sales of the ETG increased 34% to $15,143,000 for the second quarter of fiscal 2004 from $11,288,000 for the second quarter of fiscal 2003 and increased 27% to $27,082,000 for the first six months of fiscal 2004 from $21,288,000 for the first six months of fiscal 2003. The increase in sales for the second quarter and the first six months of fiscal 2004 is primarily due to the acquisition of Sierra Microwave Technology in December 2003. Operating income of the ETG increased 94% to $3,703,000 for the second quarter of fiscal 2004 from $1,904,000 for the second quarter of fiscal 2003 and increased 132% to $6,187,000 for the first six months of fiscal 2004 from $2,672,000 for the first six months of fiscal 2003. The increase in operating income for the second quarter and the first six months of fiscal 2004 reflects the acquisition of Sierra and sales of higher margin products. Laurans A. Mendelson, HEICO's Chairman, President & Chief Executive Officer, remarked, "We are pleased to report both increased sales and improved margins in each of our business segments, reflecting both organic growth and growth through acquiring profitable, well-managed businesses. We also believe that our ongoing new product development efforts and strategic relationships with some of the world's major airlines within the Flight Support Group contributed to our improved operating results. With our recently announced strategic relationship with Japan Airlines, we now have six unique partner positions with major international airlines. As we continue to add new products and further penetrate our markets, we expect the Flight Support Group's operating margins to continue to improve during the balance of fiscal 2004, while maintaining our strong operating margins in our Electronic Technologies Group. We are also pleased to note continued strong cash flow. Cash flow from operating activities in the second quarter of fiscal 2004 totaled $9 million, allowing us to reduce borrowings under our revolving credit facility by $10 million in the quarter. As we look forward to the second half of fiscal 2004, we expect further improvements in our sales and operating results. Based on current market conditions, we continue to target fiscal 2004 sales and earnings growth of at least 15% and 30%, respectively, over fiscal 2003. The Company does not give guidance on quarterly sales and earnings." - more -
