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, 2003. The October 31, 2003 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 of only normal recurring accruals) necessary for a fair presentation of the condensed consolidated balance sheets, statements of operations and cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2004 are not necessarily indicative of the results which may be expected for the entire fiscal year. STOCK DIVIDEND In December 2003, the Company's Board of Directors declared a 10% stock dividend on both its Common Stock and its Class A Common Stock that was paid in shares of Class A Common Stock on January 16, 2004 to shareholders of record as of January 6, 2004. All common stock share and per share information has been adjusted retroactively to give effect to the stock dividend. STOCK BASED COMPENSATION The Company accounts for stock-based employee compensation using the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees," and related Interpretations. Accordingly, compensation expense has been recorded in the accompanying condensed consolidated financial statements for those options granted below fair market value of the underlying stock on the date of grant. 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 (an alternative method) of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation," to stock-based employee compensation. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. 5

THREE MONTHS ENDED JANUARY 31, ------------------------------ 2004 2003 ------------- -------------- Net income, as reported $ 3,241,000 $ 2,834,000 Add: Stock-based employee compensation expense included in reported net income, net of related tax effects -- 1,000 Deduct: Total stock-based employee compensation expense determined under a fair-value method for all awards, net of related tax effects (386,000) (413,000) ------------- -------------- Pro forma net income $ 2,855,000 $ 2,422,000 ============= ============== Net income per share: Basic - as reported $ .14 $ .12 Basic - pro forma $ .12 $ .10 Diluted - as reported $ .13 $ .12 Diluted - pro forma $ .11 $ .10 NEW ACCOUNTING PRONOUNCEMENT In January 2003, the FASB issued FASB Interpretation No. 46 (FIN 46), "Consolidation of Variable Interest Entities." This Interpretation, which was revised in December 2003, clarifies the application of Accounting Research Bulletin No. 51, "Consolidated Financial Statements," to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 requires an enterprise to consolidate a variable interest entity if that enterprise will absorb a majority of the entity's expected losses, is entitled to receive a majority of the entity's expected residual returns, or both. FIN 46 also requires disclosures about unconsolidated variable interest entities in which an enterprise holds a significant variable interest. FIN 46 was immediately effective for variable interest entities created or entered into after January 31, 2003 and is effective in the first reporting period ending after December 15, 2003 for variable interest entities in which an enterprise holds a variable interest that it acquired before February 1, 2003. The adoption of FIN 46 did not have a material effect on the Company's results of operations or financial position. 2. ACQUISITION In December 2003, the Company, through its HEICO Electronic Technologies Corp. subsidiary, acquired an 80% interest in the assets and business of Sierra Microwave Technology, Inc., (Sierra). Under the transaction, the Company formed a new subsidiary, Sierra Microwave Technology, LLC (Sierra LLC), which acquired substantially all of the assets and certain liabilities of Sierra. The new subsidiary is owned 80% by the Company and 20% by certain members of Sierra's management group. The results of operations of Sierra LLC were included in the Company's results of operations effective December 2003. The purchase price was paid principally in cash using proceeds from the Company's revolving credit facility and with some 6

shares of the Company's Class A Common Stock. The purchase price of the acquisition was not significant to the Company's condensed consolidated financial statements and the pro forma consolidated operating results assuming Sierra had been acquired as of the beginning of fiscal 2004 would not have been materially different from the reported results. The allocation of the purchase price to the acquired net assets is preliminary while the Company obtains final information regarding the fair value of assets acquired and liabilities assumed. Sierra LLC is engaged in the design and manufacture of certain niche microwave components used in satellites and military products. 3.

Amortization expense of other intangible assets for the three months ended January 31, 2004 was $27,000.

Warranty reserves are included in the Company's condensed consolidated balance sheets under the caption "Accrued expenses and other current liabilities." The amount recognized is based on historical claims cost experience. Based on an analysis of such cost experience, the Company reduced its estimated warranty liability in the first quarter of fiscal 2004. Changes in the product warranty liability for the three months ended January 31, 2004 are as follows: Balance as of October 31, 2003 $ 633,000 Change in estimate of warranty liability (491,000) Accruals for warranties issued during the period 34,000 Warranty claims settled during the period (33,000) ---------- Balance as of January 31, 2004 $ 143,000 ========== As partial consideration in the acquisition of Inertial Airline Services, Inc. (IAS) in August 2001, the Company issued $5 million in HEICO Class A Common Stock (318,960 shares) and guaranteed that the resale value of such Class A Common Stock would be at least $5 million through August 31, 2004. Concurrent with the acquisition, the Company loaned the seller $5 million, which was due August 31, 2004 and secured by the 318,960 shares of HEICO Class A Common Stock. The loan is shown as a reduction of shareholders' equity in the Company's condensed consolidated balance sheets under the caption, "Note receivable secured by Class A Common Stock." In October 2003, the seller sold 220,000 shares of the HEICO Class A Common Stock and the Company received net proceeds of $2.1 million to reduce the note receivable. In February 2004, the Company received net proceeds of $1.2 million from the seller upon the sale of the remaining 98,960 shares of the HEICO Class A Common Stock. Pursuant to the Company's guarantee that the aggregate resale value of the 318,960 shares of Class A 11

Common Stock would be at least $5 million, the $1.7 million difference between the guaranteed value and the $3.3 million of aggregate net proceeds ($2.1 million received in October 2003 and $1.2 million received in February 2004) from the sales of the Class A Common Stock has been recorded as a reduction of capital in excess of par value and the note receivable as of January 31, 2004. As part of the agreement to acquire an 80% interest in Sierra (see Note 2), the Company has the right to purchase the minority interests in approximately ten years, or sooner under certain conditions, and the minority holders have the right to cause the Company to purchase their interests commencing in approximately five years, or sooner under certain conditions. LITIGATION The Company is involved in various legal actions arising in the normal course of business. Based upon the Company's and its legal counsel's evaluations of any claims or assessments, management is of the opinion that the outcome of these matters will not have a significant effect on the Company's condensed consolidated financial statements. 12

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, 2003. 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. 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. THREE MONTHS ENDED JANUARY 31, ------------------------------ 2004 2003 ------------- -------------- Net sales $ 46,151,000 $ 41,788,000 ------------- -------------- Cost of sales 30,615,000 28,012,000 Selling, general and administrative expenses 8,963,000 8,247,000 ------------- -------------- Total operating costs and expenses 39,578,000 36,259,000 ------------- -------------- Operating income $ 6,573,000 $ 5,529,000 ============= ============== 13

THREE MONTHS ENDED JANUARY 31, ------------------------------ 2004 2003 ------------- -------------- Net sales by segment: Flight Support Group $ 34,257,000 $ 31,886,000 Electronic Technologies Group 11,939,000 10,000,000 Intersegment sales (45,000) (98,000) ------------- -------------- $ 46,151,000 $ 41,788,000 ============= ============== Operating income by segment: Flight Support Group $ 5,326,000 $ 5,377,000 Electronic Technologies Group 2,484,000 768,000 Other, primarily corporate (1,237,000) (616,000) ------------- -------------- $ 6,573,000 $ 5,529,000 ============= ============== Net sales 100.0% 100.0% Gross profit 33.7% 33.0% Selling, general and administrative expense 19.4% 19.7% Operating income 14.2% 13.2% Interest expense 0.7% 0.8% Interest income and other (expense) income -- 0.2% Income tax expense 4.7% 4.4% Minority interests' share of income 1.8% 1.4% Net income 7.0% 6.8% COMPARISON OF FIRST THREE MONTHS OF FISCAL 2004 TO FIRST THREE MONTHS OF FISCAL 2003 Net Sales Net sales for the first three months of fiscal 2004 totaled $46.2 million, compared to net sales of $41.8 million for the first three months of fiscal 2003. The increase in net sales reflects an increase of $2.4 million (7% increase) to $34.3 million in sales within the FSG, and an increase of $1.9 million (a 19% increase) to $11.9 million in sales within the ETG. The FSG's sales increase primarily reflects improved demand for its aftermarket replacement parts and repair and overhaul services, which reflects some recovery within the commercial airline industry, as well as increased sales of new products. The increase in sales within the ETG primarily resulted from the acquisition of Sierra Microwave Technology, Inc. (Sierra) in December 2003. Gross Profits and Operating Expenses The Company's gross profit margin averaged 33.7% for the first three months of fiscal 2004 as compared to 33.0% for the first three months of fiscal 2003, reflecting higher margins within the ETG offset by a small decrease in the FSG's gross profit margin. The ETG's gross profit margin increase was primarily due to the acquisition of Sierra and sales of higher margin products. The FSG's gross profit margin decrease was principally due to higher costs from write-offs of excess inventory, partially offset by a reduction of its product warranty reserve and lower research and development expenses as a percentage of net sales in the first quarter of fiscal 2004. Consolidated cost of sales amounts for the first three months of fiscal 2004 and fiscal 2003 include approximately $2.1 million and $2.2 million, respectively, of new product research and development expenses. 14

Selling, general and administrative (SG&A) expenses were $9.0 million and $8.2 million for the first three months of fiscal 2004 and fiscal 2003, respectively. The increase in SG&A expenses is mainly due an increase in Corporate expenses. Corporate expenses in the first quarter of fiscal 2003 reflected a reversal of approximately $400,000 of professional fees that were accrued at the end of fiscal 2002 pursuant to a contractual arrangement that was renegotiated in the first quarter of fiscal 2003. As a percentage of net sales, SG&A expenses decreased to 19.4% for the first three months of fiscal 2004 compared to 19.7% for the first three months of fiscal 2003. The decrease as a percentage of sales is due to higher sales volumes within the FSG and ETG. Operating Income Operating income of $6.6 million for the first three months of fiscal 2004 was 18.9% higher than operating income of $5.5 million for the first three months of fiscal 2003. The increase in operating income reflects a $1.7 million increase in operating income of the ETG from $0.8 million for the first three months of fiscal 2003 to $2.5 million for the first three months of fiscal 2004, partially offset by a $0.6 million increase in Corporate expenses. As a percentage of net sales, operating income increased from 13.2% in the first three months of fiscal 2003 to 14.2% in the first three months of fiscal 2004. 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 7.7% in the first three months of fiscal 2003 to 20.8% in the first three months of fiscal 2004 offset by a slight decrease in the FSG's operating income as a percentage of net sales from 16.9% in the first three months of fiscal 2003 to 15.5% in the first three months of fiscal 2004. The increase in the ETG's operating income and operating income as a percentage of net sales reflects the purchase of Sierra and the increased gross margins, discussed previously. The decrease in the FSG's operating income as a percentage of net sales reflects the lower gross profit margins discussed previously. Interest Expense Interest expense in the first three months of fiscal 2004 and fiscal 2003 were comparable as average borrowings outstanding and associated interest rates remained at approximately the same levels. Interest Income and Other (Expense) Income Interest income and other (expense) income in the first three months of fiscal 2004 and fiscal 2003 were not material. Income Tax Expense The Company's effective tax rate decreased from 35.3% for the first three months of fiscal 2003 to 34.5% for the first three months of fiscal 2004 as the minority interests' share of the income of Sierra Microwave Technology, LLC (Sierra LLC) is excluded from the Company's income that is subject to federal income taxes, and due to a higher tax benefit on foreign sales. 15

Minority Interests' Share of Income Minority interests' share of income of consolidated subsidiaries relates to the minority interests held in HEICO Aerospace and the 20% minority interest held in Sierra LLC. The increase from the first three months of fiscal 2003 to the first three months of fiscal 2004 was primarily attributable to income of Sierra LLC. Net Income The Company's net income was $3.2 million, or $.13 per diluted share, in the first three months of fiscal 2004 compared to $2.8 million, or $.12 per diluted share, in the first three months of fiscal 2003. Outlook The Company reported increased sales in its two business segments reflecting both organic growth and growth through acquisitions. The Company believes that the FSG's operating margins will continue to improve during the balance of fiscal 2004 while maintaining the strong operating margins in the ETG. Based on the current strengthening of the general economy and the markets in which the Company participates and the Company's continued success in introducing new products and services, the Company continues to target growth in fiscal 2004 sales and earnings over fiscal 2003 results. 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 interest and principal on debt, capital expenditures, cash dividends and increases in working capital. The Company believes that its operating cash flow 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 $7.7 million for the first three months of fiscal 2004, consisting primarily of net income of $3.2 million, depreciation and amortization of $1.6 million, a deferred income tax provision of $1.2 million, a tax benefit on stock option exercises of $1.3 million and minority interests' share of income of consolidated subsidiaries of $0.8 million, partially offset by an increase in net operating assets of $0.3 million. 16

Investing Activities Net cash used in investing activities during the first three months of fiscal 2004 related primarily to the acquisition of Sierra and capital expenditures totaling $1.0 million for building improvements at certain manufacturing facilities and equipment purchases. Financing Activities Net cash provided by financing activities during the first three months of fiscal 2004 primarily related to net borrowings of $22.0 million on the Company's revolving credit facility primarily to fund the acquisition referenced above, partially offset by the payment of $0.6 million in cash dividends on the Company's common stock. OFF-BALANCE SHEET ARRANGEMENTS The Company has arranged for standby letters of credit aggregating to $1.2 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 $0.5 million letter of credit expiring July 2004. These letters of credit are supported by the Company's $120 million 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 Sierra (see Note 2 to the condensed consolidated financial statements), the Company has the right to purchase the minority interests in approximately ten years, or sooner under certain conditions, and the minority holders have the right to cause the Company to purchase their interests commencing in approximately five years, or sooner under certain conditions. NEW ACCOUNTING PRONOUNCEMENT In January 2003, the FASB issued FASB Interpretation No. 46 (FIN 46), "Consolidation of Variable Interest Entities." This Interpretation, which was revised in December 2003, clarifies the application of Accounting Research Bulletin No. 51, "Consolidated Financial Statements," to certain entities in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. FIN 46 requires an enterprise to consolidate a variable interest entity if that enterprise will absorb a majority of the entity's expected losses, is entitled to receive a majority of the entity's expected residual returns, or both. FIN 46 also requires disclosures about unconsolidated variable interest entities in which an enterprise holds a significant variable interest. FIN 46 was immediately effective for variable interest entities created or entered into after January 31, 2003 and is effective in the first reporting period ending after December 15, 2003 for variable interest entities in which an enterprise holds a variable interest that it acquired before February 1, 2003. The adoption of FIN 46 did not have a material effect on the Company's results of operations or financial position. 17

FORWARD-LOOKING STATEMENTS The Private Securities Litigation Reform Act of 1995 (the Act) provides a safe harbor for forward-looking statements made by or on behalf of the Company. The Company and its representatives may from time to time make written or oral statements that are "forward-looking," including statements contained in this report and other filings with the Securities and Exchange Commission and in reports to the Company's shareholders. Management believes that all statements that express expectations and projections with respect to future matters could 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, 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, competition from existing and new competitors, 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. For an enterprise such as the Company, a wide range of factors could materially affect future developments and performance. A list of such factors is set forth in the Company's Annual Report on Form 10-K for the year ended October 31, 2003. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. 18

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 January 31, 2004, a hypothetical 10% increase in interest rates would increase the Company's interest expense by approximately $73,000 on an annual basis. 19

ITEM 4. CONTROLS AND PROCEDURES EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES The Company's Chief Executive Officer and its Chief Financial Officer concluded that the Company's disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) are effective, based on their evaluation as of the end of the period covered by this quarterly report on Form 10-Q. CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING There were no changes in the Company's internal control over financial reporting 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. 20
