HEICO CORPORATION AND SUBSIDIARIES NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS - UNAUDITED 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements of HEICO Corporation and its subsidiaries (the "Company") have been prepared in conformity with accounting principles generally accepted in the United States of America for interim financial information and in accordance with the instructions to Form 10-Q. Therefore, the condensed consolidated financial statements do not include all information and footnotes normally included in annual consolidated financial statements and should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended October 31, 2005. The October 31, 2005 Condensed Consolidated Balance Sheet has been derived from the Company's audited consolidated financial statements. In the opinion of management, the unaudited condensed consolidated financial statements contain all adjustments (consisting principally of normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of operations and statements of cash flows for such interim periods presented. The results of operations for the six months ended April 30, 2006 are not necessarily indicative of the results which may be expected for the entire fiscal year. STOCK BASED COMPENSATION Effective November 1, 2005, the Company adopted Statement of Financial Accounting Standards ("SFAS") No. 123(R), "Share-Based Payment", as interpreted by the Securities and Exchange Commission in Staff Accounting Bulletin No. 107 and began recording compensation expense associated with stock options. SFAS No. 123(R) requires companies to recognize in the statement of operations the cost of employee services received in exchange for awards of equity instruments based on the grant date fair value of those awards (with limited exceptions). Prior to the adoption of SFAS No. 123(R), the Company accounted for stock-based employee compensation using the intrinsic value method prescribed by Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued to Employees". Accordingly, compensation expense had only been recorded in the consolidated financial statements for any stock options granted below fair market value of the underlying stock as of the date of grant. The Company adopted the modified prospective transition method provided for under SFAS 123(R) and accordingly, prior period results have not been retroactively adjusted. The modified prospective transition method requires that stock-based compensation expense be recorded for (i) all new stock options granted on or after November 1, 2005 based on the grant date fair value determined under the provisions of SFAS 123(R) and (ii) all unvested stock options granted prior to November 1, 2005 based on the grant date fair value as determined under the provisions of SFAS No. 123. 5

Beginning in fiscal 2006, the Company has presented the cash flows resulting from tax deductions in excess of the cumulative compensation cost recognized for stock options exercised ("excess tax benefit") as a financing activity in the Condensed Consolidated Statements of Cash Flows as prescribed by SFAS No. 123(R). Prior to the adoption of SFAS No. 123(R), the Company presented all tax benefits resulting from stock option exercises as an operating activity in the Condensed Consolidated Statements of Cash Flows. For the six months ended April 30, 2006, the excess tax benefit from stock option exercises of $1,135,000 was presented in financing activities in the Company's Condensed Consolidated Statements of Cash Flows. As a result of the adoption of SFAS No. 123(R), the Company's net income for the six months and three months ended April 30, 2006 includes compensation expense of $887,000 and $459,000, respectively, and income tax benefit related to the Company's stock options of $267,000 and $141,000, respectively. Substantially all of the stock option compensation expense was recorded as a component of selling, general and administrative expenses in the Company's Condensed Consolidated Statement of Operations. The following table illustrates the pro forma effects on net income and net income per share as if the Company had applied the fair value recognition provisions of SFAS No. 123 to stock-based compensation during the six months and three months ended April 30, 2005: SIX MONTHS ENDED THREE MONTHS ENDED APRIL 30, 2005 APRIL 30, 2005 ---------------- ------------------ Net income, as reported $ 10,141,000 $ 5,713,000 Add: Stock-based employee compensation expense included in reported net income, net of tax 1,000 1,000 Deduct: Stock-based employee compensation expense determined under a fair-value method, net of tax (622,000) (298,000) ---------------- ------------------ Pro forma net income $ 9,520,000 $ 5,416,000 ================ ================== Net income per share: Basic - as reported $ .42 $ .23 Basic - pro forma $ .39 $ .22 Diluted - as reported $ .39 $ .22 Diluted - pro forma $ .36 $ .21 Further information regarding stock options can be found in Note 7, Stock Options. 6

OTHER NEW ACCOUNTING PRONOUNCEMENTS In November 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No. 151, "Inventory Costs, an amendment of ARB No. 43, Chapter 4". SFAS No. 151 requires the allocation of fixed production overhead costs be based on the normal capacity of the production facilities and unallocated overhead costs recognized as an expense in the period incurred. The Statement also clarifies that abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and wasted materials (spoilage) are required to be recognized as current period charges. The provisions of SFAS No. 151 are effective for fiscal years beginning after June 15, 2005. The adoption of SFAS No. 151 did not have a material effect on the Company's results of operations, financial position, or cash flows. In March 2005, the FASB issued FASB Interpretation No. 47 ("FIN 47"), "Accounting for Conditional Asset Retirement Obligations--an interpretation of FASB Statement No. 143." This Interpretation clarifies the timing of liability recognition for legal obligations associated with an asset retirement when the timing and (or) method of settling the obligation are conditional on a future event that may or may not be within the control of the entity. FIN 47 is effective no later than the end of fiscal years ending after December 15, 2005. The Company does not expect the adoption of FIN 47 to have a material effect on its results of operations, financial position, or cash flows. In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3." SFAS No. 154 changes the requirements for the accounting and reporting of a change in accounting principle. The Statement eliminates the requirement in APB Opinion No. 20 to include the cumulative effect of changes in accounting principle in the income statement in the period of change, and instead requires that changes in accounting principle be retrospectively applied unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. The Statement applies to all voluntary changes in accounting principle. SFAS No. 154 is effective for changes made in fiscal years beginning after December 15, 2005. The Company does not expect the adoption of SFAS No. 154 to have a material effect on its results of operations, financial position, or cash flows. 2. ACQUISITIONS In November 2005, the Company, through its HEICO Aerospace Holdings Corp. subsidiary, acquired a 51% interest in the assets and business of Seal Dynamics LLC ("SDI"). The remaining 49% interest is principally held by a member of SDI's management group. As part of the agreement to acquire a 51% interest in SDI, the Company has the right to purchase the remaining 49% interest over a seven-year period beginning approximately after the second anniversary of the acquisition, or sooner under certain conditions, and the minority holder has the right to cause the Company to purchase the same equity interest over the same period. SDI is a distributor and designer of FAA-approved hydraulic, pneumatic, mechanical and electro-mechanical components for the commercial, regional and general aviation markets. 7

In November 2005, the Company, through its HEICO Electronic Technologies Corp. subsidiary, acquired all of the stock of Engineering Design Team, Inc. ("EDT") and substantially all of the assets of an EDT affiliate. Subject to meeting certain earnings objectives during the first four years following the acquisition, the Company may be obligated to pay additional consideration of up to $53.0 million in aggregate. EDT specializes in the design, manufacture and sale of advanced high-technology, high-speed interface products that link devices such as telemetry receivers, digital cameras, high resolution scanners, simulation systems and test systems to almost any computer. EDT's products are utilized in homeland security, defense, medical, research, astronomical and other applications across numerous industries. The acquisitions of SDI and EDT were accounted for using the purchase method of accounting. The purchase price of each acquisition was principally paid in cash using proceeds from the Company's revolving credit facility and was not significant to the Company's consolidated financial statements individually. The allocation of the purchase price of each acquisition to the tangible and identifiable intangible assets acquired and liabilities assumed in these condensed consolidated financial statements is preliminary until the Company obtains final information regarding their fair values. The results of operations of SDI and EDT were included in the Company's results of operations effective as of the beginning of fiscal 2006. The Company's unaudited pro forma consolidated operating results for the six months ended April 30, 2005 assuming the acquisitions of SDI and EDT had been consummated as of the beginning of fiscal 2005 would have been net sales of $150,930,000, net income of $12,540,000, basic net income per share of $.51 and diluted net income per share of $.48. The Company's unaudited pro forma consolidated operating results for the three months ended April 30, 2005 assuming the acquisitions of SDI and EDT had been consummated as of the beginning of fiscal 2005 would have been net sales of $80,043,000, net income of $6,744,000, basic net income per share of $.28 and diluted net income per share of $.26. The pro forma financial information is presented for comparative purposes only and is not necessarily indicative of the results of operations that actually would have been achieved if the acquisitions had taken place as of the beginning of fiscal 2005. The unaudited pro forma financial information includes adjustments to historical amounts such as additional amortization expense related to acquired intangible assets, increased interest expense associated with borrowings to finance the acquisitions, increased performance awards under the terms of the acquisitions and the incremental minority interest in the net income of SDI. 8

Cash investing activities related to acquisitions (principally SDI and EDT), including contingent purchase price payments to previous owners of acquired businesses, and adjustments to the preliminary allocation of the purchase price of prior year acquisitions to the assets acquired and liabilities assumed for the six months ended April 30, 2006 is as follows: SIX MONTHS ENDED APRIL 30, 2006 ------------------ Fair values of assets acquired and liabilities assumed: Liabilities assumed $ 6,081,000 Minority interests in consolidated subsidiaries 5,358,000 Less: Goodwill 15,731,000 Inventories, net 11,233,000 Identifiable intangible assets 8,330,000 Accounts receivable, net 4,704,000 Accrued additional purchase consideration 2,860,000 Other assets 1,537,000 ------------------ Acquisitions and related costs, net of cash acquired $ (32,956,000) ================== Accrued additional purchase consideration in the above table represents amounts accrued as of October 31, 2005 as a component of goodwill in accordance with the agreements related to certain prior year acquisitions that were paid in fiscal 2006. 3.

STOCK OPTIONS The Company currently has two stock option plans, the 2002 Stock Option Plan ("2002 Plan") and the Non-Qualified Stock Option Plan under which stock options may be granted. The Company's 1993 Stock Option Plan ("1993 Plan") terminated in March 2003 on the tenth anniversary of its effective date. No options may be granted under the 1993 Plan after such termination date; however, options outstanding as of the termination date may be exercised pursuant to their terms. In addition, the Company granted stock options to two former shareholders of an acquired business pursuant to employment agreements entered into in connection with the acquisition in fiscal 1999. A total of 3,031,613 shares of the Company's stock are reserved for issuance to employees, directors, officers, and consultants as of April 30, 2006, including 2,869,150 shares currently under option and 162,463 shares available for future grants. Options issued under the 2002 Plan may be designated as incentive stock options or non-qualified stock options. Incentive stock options are granted with an exercise price of not less than 100% of the fair market value of the Company's common stock as of date of grant (110% thereof in certain cases) and are exercisable in percentages specified as of the date of grant over a period up to ten years. Only employees are eligible to receive incentive stock options. Non-qualified stock options under the 2002 Plan may be granted at less than fair market value and may be immediately exercisable. Options granted under the Non-Qualified Stock Option Plan may be granted with an exercise price of no less than the fair market value of the Company's common stock as of the date of grant and are generally exercisable in four equal annual installments commencing one year from the date of grant. The options granted pursuant to the 2002 Plan may be designated as Common Stock and/or Class A Common Stock in such proportions as shall be determined by the Board of Directors or the Stock Option Plan Committee in its sole discretion. The stock options granted to two former shareholders of an acquired business were fully vested and transferable as of the grant date and expire ten years from the date of grant. The exercise price of such options was the fair market 13

value as of the date of grant. Options under all stock option plans expire not later than ten years after the date of grant, unless extended by the Stock Option Plan Committee or the Board of Directors.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW This discussion of our financial condition and results of operations should be read in conjunction with our condensed consolidated financial statements and notes thereto included herein. The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates if different assumptions were used or different events ultimately transpire. The Company's critical accounting policies, some of which require management to make judgments about matters that are inherently uncertain, are described in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations," under the heading "Critical Accounting Policies" in the Company's Annual Report on Form 10-K for the year ended October 31, 2005. The Company has two operating segments: the Flight Support Group ("FSG"), consisting of HEICO Aerospace Holdings Corp. ("HEICO Aerospace") and its subsidiaries, and the Electronic Technologies Group ("ETG"), consisting of HEICO Electronic Technologies Corp. and its subsidiaries. The Company's results of operations during the six months ended April 30, 2006 have been affected by several recent acquisitions. In November 2005, the Company, through its HEICO Aerospace Holdings Corp. subsidiary, acquired a 51% interest in Seal Dynamics LLC ("SDI"). The remaining 49% interest is principally held by a member of SDI's management group. In November 2005, the Company, through its HEICO Electronic Technologies Corp. subsidiary, acquired Engineering Design Team, Inc. ("EDT") and an EDT affiliate. The purchase price of each acquisition was principally paid in cash using proceeds from the Company's revolving credit facility and was not significant to the Company's consolidated financial statements individually. The operating results of SDI and EDT were included in the Company's results of operations effective as of the beginning of fiscal 2006. For further information regarding these acquisitions, see Note 2, Acquisitions, of the Notes to Condensed Consolidated Financial Statements. During fiscal 2005, the Company, through its HEICO Electronic Technologies Corp. subsidiary, acquired Connectronics, Corp. and its affiliate, Wiremax, Ltd. (collectively "Connectronics") in December 2004, Lumina Power, Inc. ("Lumina") in February 2005, and an 85% interest in HVT Group, Inc. ("HVT") in September 2005. The remaining 15% interest is held by certain members of HVT's management group. The operating results of each acquired company were included in the Company's results of operations from their effective acquisition date. 20

As further explained within Comparison of First Six Months of Fiscal 2006 to First Six Months of Fiscal 2005, the first six months of fiscal 2006 reflects the full impact of each of the above mentioned acquisitions whereas the first six months of fiscal 2005 includes just five months of operating results of Connectronics and three months of operating results of Lumina from each of their respective aforementioned acquisition dates. As further explained within Comparison of Second Quarter of Fiscal 2006 to the Second Quarter of Fiscal 2005, the second quarter of fiscal 2006 reflects the full impact of each of the above mentioned acquisitions whereas the second quarter of fiscal 2005 includes just the operating results of Connectronics and Lumina and not of HVT, SDI and EDT, which were acquired subsequently. RESULTS OF OPERATIONS The following table sets forth the results of the Company's operations, net sales and operating income by segment, and the percentage of net sales represented by the respective items in the Company's Condensed Consolidated Statements of Operations.

COMPARISON OF FIRST SIX MONTHS OF FISCAL 2006 TO FIRST SIX MONTHS OF FISCAL 2005 Net Sales Net sales for the first six months of fiscal 2006 increased by 45.4% to $180.2 million, as compared to net sales of $124.0 million for the first six months of fiscal 2005. The increase in net sales reflects an increase of $35.9 million (a 40.6% increase) to $124.2 million in net sales within the FSG, and an increase of $20.3 million (a 56.9% increase) to $56.1 million in net sales within the ETG. The FSG's net sales increase reflects the acquisition of SDI and organic growth of approximately 14%. The organic growth reflects increased sales of new products and services as well as improved demand for the FSG's aftermarket replacement parts and repair and overhaul services, associated with continued recovery within the commercial airline industry. The ETG's net sales increase reflects the acquisitions of Connectronics, Lumina, HVT and EDT and organic growth of approximately 9% reflecting increased demand for certain products. Gross Profit and Operating Expenses The Company's gross profit margin decreased slightly to 36.4% for the first six months of fiscal 2006 as compared to 36.6% for the first six months of fiscal 2005, reflecting slightly lower margins within the FSG offset by an increase in the ETG margin. The FSG's gross profit margin decrease was due principally to a less favorable product mix including the expected impact of lower margins realized on products distributed by SDI. The ETG's gross profit margin increase was principally from improved product mix, including a higher margin product mix contributed by recent acquisitions. Consolidated cost of sales for the first six months of fiscal 2006 and 2005 includes approximately $8.2 million and $5.3 million, respectively, of new product research and development expenses. Selling, general and administrative ("SG&A") expenses were $33.7 million and $25.2 million for the first six months of fiscal 2006 and fiscal 2005, respectively. The increase in SG&A expenses was mainly due to higher operating costs, principally personnel related, associated with the aforementioned acquisitions, the increase in net sales discussed above, an increase in corporate expenses and stock option compensation expense (see Stock Based Compensation below). Corporate expenses are up due to increased costs to comply with the Sarbanes-Oxley Act of 2002 and higher accrued performance awards. The majority of such costs incurred in fiscal 2005 were not incurred until the second half of fiscal 2005. As a percentage of net sales, SG&A expenses decreased to 18.7% for the first six months of fiscal 2006 compared to 20.4% for the first six months of fiscal 2005. The decrease as a percentage of net sales is due to improved efficiencies in controlling costs while increasing revenues. Operating Income Operating income for the first six months of fiscal 2006 increased by 58.8% to $31.9 million, compared to operating income of $20.1 million for the first six months of fiscal 2005. The increase in operating income reflects an increase of $6.8 million (a 41.8% increase) to $23.3 million in 22

operating income of the FSG in the first six months of fiscal 2006 from $16.5 million for the first six months of fiscal 2005. Operating income of the ETG increased $7.7 million (a 115.0% increase) to $14.4 million for the first six months of fiscal 2006 from $6.7 million for the first six months of fiscal 2005. These increases were partially offset by the aforementioned increase in corporate expenses. As a percentage of net sales, operating income increased from 16.2% in the first six months of fiscal 2005 to 17.7% in the first six months of fiscal 2006. The increase in operating income as a percentage of net sales reflects an increase in the FSG's operating income as a percentage of net sales from 18.6% in the first six months of fiscal 2005 to 18.8% in the first six months of fiscal 2006 and an increase in the ETG's operating income as a percentage of net sales from 18.7% in the first six months of fiscal 2005 to 25.6% in the first six months of fiscal 2006. The increase in the FSG's operating income as a percentage of net sales reflects improved operating efficiencies. The increase in the ETG's operating income as a percentage of net sales reflects the increased gross profit margins discussed previously. Interest Expense Interest expense increased to $1,669,000 in the first six months of fiscal 2006 from $533,000 in the first six months of fiscal 2005. The increase was principally due to a higher weighted average balance outstanding under the revolving credit facility in the first six months of fiscal 2006 and higher interest rates. Interest and Other Income Interest and other income in the first six months of fiscal 2006 and fiscal 2005 were not material. Income Tax Expense The Company's effective tax rate for the first six months of fiscal 2006 decreased to 35.2% from 36.3% for the first six months of fiscal 2005. The decrease is principally due to a higher amount of the minority interests' share of income excluded from the Company's fiscal 2006 consolidated income subject to federal income taxes. Minority Interests' Share of Income Minority interests' share of income of consolidated subsidiaries relates to the minority interests held in HEICO Aerospace, including the 49% minority interest held in SDI, and the minority interests held in the ETG, which consist of the 20% minority interest held in Sierra Microwave Technology, LLC ("Sierra") and the 15% minority interest held in HVT. The increase in the minority interests' share of income for the first six months of fiscal 2006 compared to the first six months of fiscal 2005 is attributable to the acquisitions of SDI (November 2005) and HVT (September 2005) and the higher earnings of the FSG and Sierra. 23

Net Income The Company's net income was $14.3 million, or $.54 per diluted share, for the first six months of fiscal 2006 compared to $10.1 million, or $.39 per diluted share, for the first six months of fiscal 2005 reflecting the increased operating income referenced above. OUTLOOK The Company reported increased sales and operating income in its two business segments reflecting both growth through acquisitions and strong organic growth. Consolidated operating margins experienced in the first half of fiscal 2006 approximate those currently expected for the full fiscal 2006 year. Based on the Company's continued success in introducing new products and services and increasing product demand, the Company continues to target growth in fiscal 2006 sales and net income over fiscal 2005. COMPARISON OF SECOND QUARTER OF FISCAL 2006 TO SECOND QUARTER OF FISCAL 2005 Net Sales Net sales for the second quarter of fiscal 2006 increased by 37.5% to $92.1 million, as compared to net sales of $67.0 million for the second quarter of fiscal 2005. The increase in net sales reflects an increase of $16.4 million (a 35.7% increase) to $62.5 million in net sales within the FSG, and an increase of $8.6 million (a 41.1% increase) to $29.6 million in net sales within the ETG. The FSG's net sales increase reflects the acquisition of SDI and organic growth of approximately 9%. The organic growth reflects increased sales of new products and services as well as improved demand for the FSG's aftermarket replacement parts and repair and overhaul services associated with continued recovery within the commercial airline industry. The ETG's net sales increase reflects the acquisitions of HVT and EDT and organic growth of approximately 6% reflecting increased demand for certain products. Gross Profit and Operating Expenses The Company's gross profit margin decreased to 36.4% for the second quarter of fiscal 2006 as compared to 37.4% for the second quarter of fiscal 2005, reflecting lower margins within the FSG partially offset by an increase in the ETG margin. The FSG's gross profit margin decrease was due principally to a less favorable product mix including the expected impact of lower margins realized on products distributed by SDI. The ETG's gross profit margin increase was principally from improved product mix, including a higher margin product mix contributed by recent acquisitions. Consolidated cost of sales for the second quarter of fiscal 2006 and 2005 includes approximately $4.4 million and $2.9 million, respectively, of new product research and development expenses. SG&A expenses were $16.9 million and $13.6 million for the second quarter of fiscal 2006 and fiscal 2005, respectively. The increase in SG&A expenses was mainly due to higher operating costs, principally personnel related, associated with the aforementioned acquisitions, the increase in net sales discussed above, an increase in corporate expenses and stock option compensation expense (see Stock Based Compensation below). Corporate expenses are up due to increased costs 24

to comply with the Sarbanes-Oxley Act of 2002 and higher accrued performance awards. The majority of such costs incurred in fiscal 2005 were not incurred until the second half of fiscal 2005. As a percentage of net sales, SG&A expenses decreased to 18.4% for the second quarter of fiscal 2006 compared to 20.3% for the second quarter of fiscal 2005. The decrease as a percentage of net sales is due to improved efficiencies in controlling costs while increasing revenues. Operating Income Operating income for the second quarter of fiscal 2006 increased by 45.4% to $16.6 million, compared to operating income of $11.4 million for the second quarter of fiscal 2005. The increase in operating income reflects an increase of $2.1 million (a 24.4% increase) to $11.0 million in operating income of the FSG in the second quarter of fiscal 2006 from $8.9 million for the second quarter of fiscal 2005. Operating income of the ETG increased $4.5 million (a 105.1% increase) to $8.7 million for the second quarter of fiscal 2006 from $4.2 million for the second quarter of fiscal 2005. These increases were partially offset by the aforementioned increase in corporate expenses. As a percentage of net sales, operating income increased from 17.1% in the second quarter of fiscal 2005 to 18.0% in the second quarter of fiscal 2006. The increase in operating income as a percentage of net sales reflects an increase in the ETG's operating income as a percentage of net sales from 20.1% in the second quarter of fiscal 2005 to 29.2% in the second quarter of fiscal 2006 offset by a decrease in the FSG's operating income as a percentage of net sales from 19.3% in the second quarter of fiscal 2005 to 17.7% in the second quarter of fiscal 2006. The increase in the ETG's operating income as a percentage of net sales reflects the increased gross profit margins discussed previously. The decrease in the FSG's operating income as a percentage of net sales reflects the decreased gross profit margins discussed previously partially offset by improved operating efficiencies. Interest Expense Interest expense increased to $861,000 in the second quarter of fiscal 2006 from $300,000 in the second quarter of fiscal 2005. The increase was principally due to a higher weighted average balance outstanding under the revolving credit facility in the second quarter of fiscal 2006 attributable to borrowings related to acquisitions and higher interest rates. Interest and Other Income Interest and other income in the second quarter of fiscal 2006 and 2005 were not material. Income Tax Expense The Company's effective tax rate for the second quarter of fiscal 2006 decreased to 36.2% from 37.7% for the second quarter of fiscal 2005. The decrease is principally due to a higher amount of the minority interests' share of income excluded from the Company's fiscal 2006 consolidated income subject to federal income taxes. 25

Minority Interests' Share of Income Minority interests' share of income of consolidated subsidiaries relates to the minority interests held in HEICO Aerospace, including the 49% minority interest held in SDI, and the minority interests held in the ETG, which consist of the 20% minority interest held in Sierra and the 15% minority interest held in HVT. The increase in the minority interests' share of income for the second quarter of fiscal 2006 compared to the second quarter of fiscal 2005 is attributable to the acquisitions of SDI (November 2005) and HVT (September 2005) and the higher earnings of the FSG and Sierra. Net Income The Company's net income was $7.5 million, or $.28 per diluted share, for the second quarter of fiscal 2006 compared to $5.7 million, or $.22 per diluted share, for the second quarter of fiscal 2005 reflecting the increased operating income referenced above, partially offset by the increased minority interests' share of income of certain consolidated subsidiaries. LIQUIDITY AND CAPITAL RESOURCES The Company generates cash primarily from its operating activities and financing activities, including borrowings under long-term credit agreements. Principal uses of cash by the Company include acquisitions, payments of principal and interest on debt, capital expenditures, cash dividends and increases in working capital. The Company believes that its net cash provided by operating activities and available borrowings under its revolving credit facility will be sufficient to fund cash requirements for the foreseeable future. Operating Activities Net cash provided by operating activities was $7.4 million for the first six months of fiscal 2006, consisting primarily of net income of $14.3 million, minority interests' share of income of consolidated subsidiaries of $5.5 million, depreciation and amortization of $4.3 million, a tax benefit on stock option exercises of $2.4 million, a deferred income tax provision of $1.7 million, and stock option compensation expense of $.9 million, partially offset by an increase in net operating assets of $20.6 million and the presentation of $1.1 million of excess tax benefit from stock option exercises as a financing activity in accordance with the provisions of SFAS No. 123(R) (see Stock Based Compensation below). The increase in net operating assets (current assets used in operating activities net of current liabilities) primarily reflects a higher investment in inventories by the FSG required to meet increased sales demand associated with new product offerings, sales growth and increased lead times on certain raw materials; an increase in accounts receivable due to sales growth; and the payment of performance awards and income taxes that were accrued as of October 31, 2005. Net cash provided by operating activities decreased from $11.5 million for the first six months of fiscal 2005 principally as a result of the increase in net operating assets referenced above, partially offset by the increase in net income and the minority interests' share of income. 26

Investing Activities Net cash used in investing activities during the first six months of fiscal 2006 related primarily to acquisitions and related costs (principally SDI and EDT) of $33.0 million and capital expenditures totaling $4.6 million. Financing Activities Net cash provided by financing activities during the first six months of fiscal 2006 primarily related to borrowings of $34.0 million on the Company's revolving credit facility principally used to fund the aforementioned acquisitions, proceeds from stock option exercises of $3.8 million and $1.1 million of excess tax benefit from stock option exercises classified as a financing activity in accordance with the provisions of SFAS No. 123(R), partially offset by repayments of $7.0 million on the Company's revolving credit facility and the payment of $1.0 million in cash dividends on the Company's common stock. OFF-BALANCE SHEET ARRANGEMENTS The Company has arranged for standby letters of credit aggregating $2.2 million to meet the security requirement of its insurance company for potential workers' compensation claims and one of the Company's subsidiaries has guaranteed its performance related to a customer contract through a letter of credit for $.1 million, expiring August 2006. These letters of credit are supported by the Company's revolving credit facility. In addition, the Company's industrial development revenue bonds are secured by a $2.0 million letter of credit expiring April 2008 and a mortgage on the related properties pledged as collateral. As part of the agreement to acquire an 80% interest in a subsidiary by the ETG in fiscal 2004, the Company has the right to purchase the minority interests beginning at approximately the tenth anniversary of the acquisition, or sooner under certain conditions, and the minority holders have the right to cause the Company to purchase their interests commencing on approximately the fifth anniversary of the acquisition, or sooner under certain conditions. As part of the agreement to purchase a subsidiary by the ETG in fiscal 2005, the Company may be obligated to pay additional purchase consideration of up to $3.8 million in aggregate should the subsidiary meet certain earnings objectives during the first four years following the acquisition. In the second quarter of 2006, the Company paid $2.2 million of such additional purchase consideration based on the subsidiary's earnings relative to target for the first year. As part of the agreement to purchase a subsidiary by the ETG in fiscal 2005, the Company may be obligated to pay additional purchase consideration currently estimated to total up to $2.3 million should the subsidiary meet certain product line-related earnings objectives during the fourth and fifth years following the acquisition. The additional purchase consideration will be accrued when the earnings objectives are met. As part of the agreement to acquire an 85% interest in a subsidiary by the ETG in fiscal 2005, the minority holders have the right to cause the Company to purchase their interests over a four-year period starting around the second anniversary of the acquisition, or sooner under certain conditions. 27

As part of the agreement to acquire a 51% interest in a subsidiary by the FSG in fiscal 2006, the Company has the right to purchase 28% of the equity interests of the subsidiary over a four-year period beginning approximately after the second anniversary of the acquisition, or sooner under certain conditions, and the minority holder has the right to cause the Company to purchase the same equity interest over the same period. Further, the Company has the right to purchase the remaining 21% of the equity interests of the subsidiary over a three-year period beginning approximately after the fourth anniversary of the acquisition, or sooner under certain conditions, and the minority holder has the right to cause the Company to purchase the same equity interest over the same period. As part of the agreement to acquire a subsidiary by the ETG in fiscal 2006, the Company may be obligated to pay additional consideration of up to $53.0 million in aggregate during the first four years following the acquisition. The maximum amount of additional consideration that may become payable by year is $6.8 million in fiscal 2006, $9.2 million in fiscal 2007, $17.8 million in fiscal 2008 and $19.2 million in fiscal 2009. The additional purchase consideration will be accrued when the earnings objectives are met. The Company has also accrued additional purchase consideration aggregating $.5 million as of April 30, 2006 in accordance with the agreements related to certain acquisitions based principally on the actual value of the net assets acquired. The Company expects to pay this amount in fiscal 2006. As part of an agreement for exclusive license rights to intellectual property, one of the subsidiaries of the ETG has guaranteed minimum royalty payments aggregating $.4 million through fiscal 2007. STOCK BASED COMPENSATION Effective November 1, 2005, the Company adopted Statement of Financial Accounting Standards ("SFAS") No. 123(R), "Share-Based Payment", as interpreted by the Securities and Exchange Commission in Staff Accounting Bulletin No. 107 and began recording compensation expense associated with stock options. SFAS No. 123(R) requires companies to recognize in the statement of operations the cost of employee services received in exchange for awards of equity instruments based on the grant date fair value of those awards (with limited exceptions). Prior to the adoption of SFAS No. 123(R), the Company accounted for stock-based employee compensation using the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees". Accordingly, compensation expense had only been recorded in the consolidated financial statements for any stock options granted below fair market value of the underlying stock as of the date of grant. The Company adopted the modified prospective transition method provided for under SFAS 123(R) and accordingly, prior period results have not been retroactively adjusted. The modified prospective transition method requires that stock-based compensation expense be recorded for (i) all new stock options granted on or after November 1, 2005 based on the grant date fair value 28

determined under the provisions of SFAS 123(R) and (ii) all unvested stock options granted prior to November 1, 2005 based on the grant date fair value as determined under the provisions of SFAS No. 123. Beginning in fiscal 2006, the Company has presented the cash flows resulting from tax deductions in excess of the cumulative compensation cost recognized for stock options exercised ("excess tax benefit") as a financing activity in the Condensed Consolidated Statements of Cash Flows as prescribed by SFAS No. 123(R). Prior to the adoption of SFAS No. 123(R), the Company presented all tax benefits resulting from stock option exercises as an operating activity in the Condensed Consolidated Statements of Cash Flows. For the six months ended April 30, 2006, the Company reclassified $1,135,000 of excess tax benefit from stock option exercises from operating activities to financing activities in its Condensed Consolidated Statements of Cash Flows. As a result of the adoption of SFAS No. 123(R), the Company's net income for the six months and three months ended April 30, 2006 includes compensation expense of $887,000 and $459,000 , respectively, and income tax benefit related to the Company's stock options of $267,000 and $141,000, respectively. Substantially all of the stock option compensation expense was recorded as a component of selling, general and administrative expenses in the Company's Condensed Consolidated Statement of Operations. As of April 30, 2006, there was $1.3 million of pretax unrecognized compensation expense related to nonvested stock options, which is expected to be recognized over a weighted average period of approximately 1.6 years. Further information regarding stock options can be found in Note 7, Stock Options, of the Notes to Condensed Consolidated Financial Statements. OTHER NEW ACCOUNTING PRONOUNCEMENTS In November 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No. 151, "Inventory Costs, an amendment of ARB No. 43, Chapter 4". SFAS No. 151 requires the allocation of fixed production overhead costs be based on the normal capacity of the production facilities and unallocated overhead costs recognized as an expense in the period incurred. The Statement also clarifies that abnormal inventory costs such as costs of idle facilities, excess freight and handling costs, and wasted materials (spoilage) are required to be recognized as current period charges. The provisions of SFAS No. 151 are effective for fiscal years beginning after June 15, 2005. The adoption of SFAS No. 151 did not have a material effect on the Company's results of operations, financial position, or cash flows. In March 2005, the FASB issued FASB Interpretation No. 47 ("FIN 47"), "Accounting for Conditional Asset Retirement Obligations--an interpretation of FASB Statement No. 143." This Interpretation clarifies the timing of liability recognition for legal obligations associated with an asset retirement when the timing and (or) method of settling the obligation are conditional on a future event that may or may not be within the control of the entity. FIN 47 is effective no later than the end of fiscal years ending after December 15, 2005. The Company does not expect the 29

adoption of SFAS No. 154 to have a material effect on its results of operations, financial position, or cash flows. In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Error Corrections, a replacement of APB Opinion No. 20 and FASB Statement No. 3." SFAS No. 154 changes the requirements for the accounting and reporting of a change in accounting principle. The Statement eliminates the requirement in APB Opinion No. 20 to include the cumulative effect of changes in accounting principle in the income statement in the period of change, and instead requires that changes in accounting principle be retrospectively applied unless it is impracticable to determine either the period-specific effects or the cumulative effect of the change. The Statement applies to all voluntary changes in accounting principle. SFAS No. 154 is effective for changes made in fiscal years beginning after December 15, 2005. The Company does not expect the adoption of SFAS No. 154 to have a material effect on its results of operations, financial position, or cash flows. FORWARD-LOOKING STATEMENTS Certain statements in this Report constitute "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. All statements contained herein that are not clearly historical in nature may be forward-looking and the words "believe," "expect," "estimate" and similar expressions are generally intended to identify forward looking statements. Any forward-looking statements contained herein, in press releases, written statements or other documents filed with the Securities and Exchange Commission or in communications and discussions with investors and analysts in the normal course of business through meetings, phone calls and conference calls, concerning our operations, economic performance and financial condition are subject to known and unknown risks, uncertainties and contingencies. We have based these forward-looking statements on our current expectations and projections about future events. All forward-looking statements involve risks and uncertainties, many of which are beyond our control, which may cause actual results, performance or achievements to differ materially from anticipated results, performance or achievements. Also, forward-looking statements are based upon management's estimates of fair values and of future costs, using currently available information. Therefore, actual results may differ materially from those expressed in or implied by those statements. Factors that could cause such differences, but are not limited to: lower demand for commercial air travel or airline fleet changes, 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. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. 30

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Substantially all of the Company's borrowings bear interest at floating interest rates. Based on the outstanding debt balance as of April 30, 2006, a hypothetical 10% increase in interest rates would increase the Company's interest expense by approximately $348,000 on an annual basis. The Company is also exposed to foreign currency exchange rate fluctuations on the United States dollar value of its foreign currency denominated transactions, which are principally in British pound sterling. A hypothetical 10% weakening in the exchange rate of the British pound sterling to the United States dollar as of April 30, 2006 would not have a material effect on the Company's results of operations or financial position. 31

ITEM 4. CONTROLS AND PROCEDURES EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES The Company's Chief Executive Officer and its Chief Financial Officer conducted an evaluation of the effectiveness of the Company's disclosure controls and procedures as of the end of the period covered by this quarterly report. Based upon that evaluation, the Company's Chief Executive Officer and its Chief Financial Officer concluded that the Company's disclosure controls and procedures are effective as of the end of the period covered by this quarterly report. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING There were no changes in the Company's internal control over financial reporting identified in connection with the evaluation referred to above that occurred during the Company's most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting. 32

PART II. OTHER INFORMATION ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS The Company did not incur any unregistered sales of its equity securities or repurchase any of its equity securities during the first six months of fiscal 2006. ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS At the Annual Meeting of Shareholders held on March 27, 2006, the Company's shareholders elected eight directors.

               disclosure controls and procedures to be designed under our

               the period in which this report is being prepared;

          d)   Disclosed in this report any change in the registrant's internal
               control over financial reporting that occurred during the
               registrant's most recent fiscal quarter (the registrant's fourth
               fiscal quarter in the case of an annual report) that has
               materially affected, or is reasonably likely to materially
               affect, the registrant's internal control over financial
               reporting; and

     (5)  The registrant's other certifying officer and I have disclosed, based
          on our most recent evaluation of internal control over financial
          reporting, to the registrant's auditors and the audit committee of the
          registrant's board of directors (or persons performing the equivalent
          functions):

          a)   All significant deficiencies and material weaknesses in the
               design or operation of internal control over financial reporting
               which are reasonably likely to adversely affect the registrant's
