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 (collectively, “HEICO,” or 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, 2023. The October 31, 2023 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, statements of comprehensive income, statements of shareholders' equity and statements of cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2024 are not necessarily indicative of the results which may be expected for the entire fiscal year.

The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. ("HFSC") and their respective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. and its subsidiaries.

New Accounting Pronouncements

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. The ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment performance and deciding how to allocate resources. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, or in fiscal 2025 for HEICO, and interim periods within fiscal years beginning one year later. Early adoption is permitted and the amendments must be applied retrospectively to all prior periods presented. The adoption of this guidance will not affect the Company's consolidated results of operations, financial position or

Index

cash flows and the Company is currently evaluating the effect the guidance will have on its disclosures.

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of specific categories in the annual effective tax rate reconciliation table and further disaggregation for reconciling items that meet a quantitative threshold. The ASU also requires the disaggregation of income taxes paid by jurisdiction. ASU 2023-09 may be applied either prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2024, or in fiscal 2026 for HEICO. Early adoption is permitted. The adoption of this guidance will not affect the Company's consolidated results of operations, financial position or cash flows and the Company is currently evaluating the effect the guidance will have on its disclosures.

2. ACQUISITION

In December 2023, the Company, through a subsidiary of HFSC, entered into an exclusive license and acquired certain assets for the capability to support the Boeing 737NG/777 Cockpit Display and Legacy Displays product lines from Honeywell International. The transaction provides the HFSC subsidiary with the exclusive capability to produce, sell, and repair Boeing 737NG/777 Cockpit Displays as well as other Legacy Displays for Boeing 717, ATR, and select business and general aviation aircraft. The purchase price of this acquisition was paid in cash using proceeds from the Company's revolving credit facility, and is not material or significant to the Company's condensed consolidated financial statements.

The allocation of the total consideration for this acquisition to the tangible and identifiable intangible assets acquired is preliminary until the Company obtains final information regarding their fair values. However, the Company does not expect any adjustment to such allocation to be material to the Company's consolidated financial statements. This acquisition’s operating results were included in the Company’s results of operations from the effective acquisition date. The amount of net sales and earnings of this acquisition included in the Condensed Consolidated Statement of Operations for the three months ended January 31, 2024 is not material. Had this acquisition occurred as of November 1, 2022, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for the three months ended January 31, 2024 and 2023 would not have been materially different than the reported amounts.

The aggregate amount of accrued customer rebates and credits included within accrued expenses and other current liabilities in the accompanying Condensed Consolidated Balance Sheets was $27.5 million as of January 31, 2024 and $24.5 million as of October 31, 2023. The total customer rebates and credits deducted within net sales for the three months ended January 31, 2024 and 2023 was $3.5 million and $2.2 million, respectively.

Research and Development Expenses

The amount of new product research and development ("R&D") expenses included in cost of sales for the three months ended January 31, 2024 and 2023 is as follows (in thousands):

Index

Redeemable Noncontrolling Interests

The holders of equity interests in certain of the Company's subsidiaries have rights ("Put Rights") that may be exercised on varying dates causing the Company to purchase their equity interests through fiscal 2032. The Put Rights, all of which relate either to common shares or membership interests in limited liability companies, provide that the cash consideration to be paid for their equity interests (the "Redemption Amount") be at fair value or a formula that management intended to reasonably approximate fair value based solely on a multiple of future earnings over a measurement period. Management's estimate of the aggregate Redemption Amount of all Put Rights that the Company could be required to pay is as follows (in thousands):


	January 31, 2024	October 31, 2023
Redeemable at fair value	$308,586	$308,472
Redeemable based on a multiple of future earnings	57,279	56,335
Redeemable noncontrolling interests	$365,865	$364,807

During fiscal 2022, the holder of a 19.9% noncontrolling equity interest in a subsidiary of the FSG that was acquired in fiscal 2015 exercised their option to cause the Company to purchase their noncontrolling interest over a four-year period ending in fiscal 2026. In December 2023, the Company acquired an additional one-fourth of such interest, which increased the Company's ownership interest in the subsidiary to 90.1%.

Accumulated Other Comprehensive Loss

Changes in the components of accumulated other comprehensive loss for the three months ended January 31, 2024 are as follows (in thousands):


	Foreign Currency Translation	Defined Benefit Pension Plan	Accumulated Other Comprehensive Loss

4. GOODWILL AND OTHER INTANGIBLE ASSETS

Changes in the carrying amount of goodwill by operating segment for the three months ended January 31, 2024 are as follows (in thousands):


	Segment		Consolidated Totals
	FSG	ETG
Balances as of October 31, 2023	$1,824,305	$1,450,022	$3,274,327

Balances as of January 31, 2024	$1,833,093	$1,457,401	$3,290,494

The goodwill acquired pertains to the fiscal 2024 acquisition described in Note 2, Acquisition, and represents the residual value after the allocation of the total consideration to the tangible and identifiable intangible assets acquired. The Company estimates that $7 million of the goodwill acquired in fiscal 2024 will be deductible for income tax purposes. Foreign currency translation adjustments are included in other comprehensive income (loss) in the Company's Condensed Consolidated Statements of Comprehensive Income. The adjustments to goodwill represent immaterial measurement period adjustments to the allocation of the purchase consideration of certain fiscal 2023 acquisitions.

6. REVENUE

Contract Balances

Contract assets (unbilled receivables) represent revenue recognized on contracts using an over-time recognition model in excess of amounts invoiced to the customer. Contract liabilities (deferred revenue) represent customer advances and billings in excess of revenue recognized and are included within accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets.

Changes in the Company’s contract assets and liabilities for the three months ended January 31, 2024 are as follows (in thousands):


	January 31, 2024	October 31, 2023	Change
Contract assets	$108,888	$111,702	($2,814)
Contract liabilities	96,117	87,556	8,561
Net contract assets	$12,771	$24,146	($11,375)

The increase in the Company's contract liabilities during the first quarter of 2024 principally reflects the receipt of advance deposits on certain customer contracts, mainly at the FSG.

The amount of revenue that the Company recognized during the first quarter of fiscal 2024 that was included in contract liabilities as of the beginning of fiscal 2024 was $26.7 million.

Remaining Performance Obligations

Backlog, which the Company believes to be the equivalent of its remaining performance obligations, represents contractually committed or firm customer orders. As of January 31, 2024, the Company had $1,444.3 million of remaining performance obligations associated with firm contracts pertaining to the majority of the products offered by the ETG and FSG. The Company

The Company maintains the HEICO Corporation Leadership Compensation Plan (the "LCP"), which is a non-qualified deferred compensation plan. The assets of the LCP principally represent cash surrender values of life insurance policies, which derive their fair values from investments in mutual funds that are managed by an insurance company, and are classified within Level 2 and valued using a market approach. Certain other assets of the LCP represent an investment in a money market fund that is classified within Level 1. The assets of the LCP are held within an irrevocable trust and classified within other assets in the Company’s Condensed Consolidated Balance Sheets. The related liabilities of the LCP are included within other long-term liabilities and accrued expenses and other current liabilities in the Company’s Condensed Consolidated Balance Sheets and have an aggregate value of $274.1 million as of January 31, 2024 and $226.2 million as of October 31, 2023.

Index

In connection with a fiscal 2023 acquisition that is part of the FSG, the Company assumed an agreement which now obligates it to pay contingent consideration of $17.5 million as certain operating entities of the acquired company met a calendar year 2023 earnings objective and obtained a certain level of new orders with deliveries scheduled in calendar year 2024, of which both targets were tied to a specific customer contract. The $17.5 million of contingent consideration accrued as of January 31, 2024 is expected to be paid in the second quarter of fiscal 2024.

As part of the agreement to acquire 80.36% of the stock of a subsidiary by the ETG in fiscal 2022, the Company may be obligated to pay contingent consideration of up to $12.1 million in fiscal 2027 based on the earnings of the acquired entity during fiscal years 2025 and 2026 provided the entity meets a certain earnings objective during each of fiscal years 2024 to 2026. As of January 31, 2024, the estimated fair value of the contingent consideration was $5.6 million.

As part of the agreement to acquire 96% of the stock of a subsidiary by the FSG in fiscal 2022, the Company may be obligated to pay contingent consideration of up to $27.4 million in fiscal 2027 based on the earnings of the acquired entity during fiscal years 2025 and 2026 provided the entity meets certain earnings objectives during each of fiscal years 2022 to 2024. As of January 31, 2024, the estimated fair value of the contingent consideration was $20.3 million.

As part of the agreement to acquire 74% of the membership interests of a subsidiary by the FSG in fiscal 2022, the Company would be obligated to pay contingent consideration of $14.1 million in fiscal 2027 only if the acquired entity met a certain earnings objective during the five-year period following the acquisition. Based on the actual earnings of the acquired entity subsequent to the acquisition and forecasted earnings over the remainder of the earnout period, the Company does not expect that the required earnings objective will be met. Accordingly, as of January 31, 2024 and October 31, 2023, the estimated fair value of the contingent consideration was $0.0 million.

As part of the agreement to acquire 89.99% of the equity interests of a subsidiary by the ETG in fiscal 2020, the Company may be obligated to pay contingent consideration of up to CAD $13.5 million, or $10.1 million, in fiscal 2025 should the acquired entity meet certain earnings objectives during fiscal 2023 and 2024. As of January 31, 2024, the estimated fair value of the contingent consideration was CAD $12.3 million, or $9.1 million.

As part of the agreement to acquire a subsidiary by the ETG in fiscal 2017, the Company paid contingent consideration of $20.0 million in December 2023 as the acquired entity met a certain earnings objective during the first six years following the acquisition.

Litigation

On April 20, 2021, an indirect subsidiary of HFSC, which was acquired in June 2020, received a grand jury subpoena from the United States District Court for the Southern District of California requiring the production of documents for the pre-acquisition time period of December 1, 2017 through February 4, 2019 related to the subsidiary's employment of a certain individual and its performance of work on certain Navy vessels during that time period. In connection with this investigation, the individual pled guilty to a charge of a misdemeanor conflict of interest, and has been suspended by the Company pending determination by the Navy whether the suspended employee should be debarred from government contracting. The Company is cooperating with the investigation, and is cooperating with the Navy. The Company has completed its production of documents responsive to the subpoena, although the Company has a continuing obligation to produce such documents should any be located. The Company cannot predict the outcome of the investigation or when the investigation will ultimately be resolved; nor can the Company reasonably estimate the possible range of loss or impact to its business, if any, that may result from this matter.

With the exception of the matter noted above, 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 material adverse effect on the Company’s results of operations, financial position or cash flows.

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.

Our critical accounting policies, 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 Estimates” in our Annual Report on Form 10-K for the year ended October 31, 2023. There have been no material changes to our critical accounting policies during the three months ended January 31, 2024.

Our business is comprised of two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. and their respective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. and its subsidiaries.

Our results of operations for the three months ended January 31, 2024 have been affected by the fiscal 2023 acquisitions as further detailed in Note 2, Acquisitions, of the Notes to Consolidated Financial Statements of our Annual Report on Form 10-K for the year ended October 31, 2023.

Comparison of First Quarter of Fiscal 2024 to First Quarter of Fiscal 2023

Net Sales

Our consolidated net sales in the first quarter of fiscal 2024 increased by 44% to $896.4 million, up from net sales of $620.9 million in the first quarter of fiscal 2023. The increase in consolidated net sales principally reflects an increase of $247.4 million (a 67% increase) to a record $618.7 million within the FSG and an increase of $30.9 million (a 12% increase) to $285.9 million within the ETG. The net sales increase in the FSG reflects $202.0 million contributed by a fiscal 2023 acquisition as well as strong organic growth of 12%. The FSG's organic net sales growth reflects increased demand within its aftermarket replacement parts and repair and overhaul parts and services product lines resulting in net sales increases of $37.9 million and $11.0 million, respectively. The net sales increase in the ETG reflects net sales of $39.4 million contributed by a fiscal 2023 acquisition, partially offset by a 5% organic net sales decline. The ETG's organic net sales decline is mainly attributable to decreased demand for its other electronics, medical and space products resulting in net sales decreases of $7.3 million, $4.7 million and $2.8 million, respectively, partially offset by increased demand for its aerospace products resulting in a net sales increase of $3.3 million. Although sales price changes were not a significant contributing factor to the change in net sales of the FSG and ETG in the first quarter of fiscal 2024, continued cost inflation may lead to higher sales prices during the remainder of fiscal 2024.

Gross Profit and Operating Expenses

Our consolidated gross profit margin was 38.7% in the first quarter of fiscal 2024, as compared to 39.3% in the first quarter of fiscal 2023 principally reflecting decreases of .3% and .2% in the FSG's and ETG's gross profit margin, respectively. The decrease in the FSG's gross profit margin principally reflects a .9% impact from higher inventory obsolescence expense, partially offset by the previously mentioned higher net sales. The reduction in the ETG's gross profit margin principally reflects a .5% impact from an increase in new product research and development expenses as well as the previously mentioned decreases in net sales for its other electronics, space and medical products, partially offset by increased demand for its aerospace products. Total new product research and development expenses included within our consolidated cost of sales were $25.1 million in the first quarter of fiscal 2024, up from $20.2 million in the first quarter of fiscal 2023.

Our consolidated selling, general and administrative ("SG&A") expenses were $166.6 million in the first quarter of fiscal 2024, as compared to $114.4 million in the first quarter of fiscal 2023. The increase in consolidated SG&A expenses principally reflects $49.1 million attributable to our fiscal 2023 acquisitions and costs incurred to support the previously mentioned net sales growth resulting in increases of $5.5 million and $2.6 million in other general and administrative expenses and other selling expenses, respectively, partially offset by a $5.0 million reduction in acquisition costs.

Index

Our consolidated SG&A expenses as a percentage of net sales were 18.6% in the first quarter of fiscal 2024, as compared to 18.4% in the first quarter of fiscal 2023. The increase in consolidated SG&A expenses as a percentage of net sales principally reflects a .6% impact from higher intangible asset amortization expense and depreciation expense, partially offset by an .8% impact from the previously mentioned lower acquisition costs.

Operating Income

Our consolidated operating income increased by 39% to $180.2 million in the first quarter of fiscal 2024, up from $129.4 million in the first quarter of fiscal 2023. The increase in consolidated operating income principally reflects a $52.5 million increase (a 63% increase) to a record $136.1 million in operating income of the FSG, partially offset by a $1.2 million decrease (a 2% decrease) to $55.3 million in operating income of the ETG. The increase in operating income of the FSG principally reflects the previously mentioned net sales growth, partially offset by an $11.1 million increase in intangible asset amortization expense and a $5.0 million increase in inventory obsolescence expense. The decrease in operating income of the ETG principally reflects a lower level of SG&A efficiencies, partially offset by the previously mentioned net sales increase and a $5.0 million decrease in acquisition costs.

Our consolidated operating income as a percentage of net sales was 20.1% in the first quarter of fiscal 2024, as compared to 20.8% in the first quarter of fiscal 2023. The decrease principally reflects a decrease in the ETG's operating income as a percentage of net sales to 19.3% in the first quarter of fiscal 2024, as compared to 22.2% in the first quarter of fiscal 2023 and a decrease in the FSG’s operating income as a percentage of net sales to 22.0% in the first quarter of fiscal 2024, as compared to 22.5% in the first quarter of fiscal 2023. The decrease in the ETG's operating income as a percentage of net sales principally reflects a 2.7% impact from an increase in SG&A expenses as a percentage of net sales as well as the previously mentioned decrease in gross profit margin. The increase in the ETG's SG&A expenses as a percentage of net sales mainly reflects the previously mentioned lower level of efficiencies, partially offset by a 2.0% impact from the previously mentioned lower acquisition costs. The decrease in the FSG’s operating income as a percentage of net sales principally reflects the previously mentioned lower gross profit margin and a .9% impact from the previously mentioned higher intangible asset amortization expense, partially offset by a .9% impact from lower performance-based compensation expense.

Interest Expense

Interest expense increased to $38.6 million in the first quarter of fiscal 2024, up from $6.1 million in the first quarter of fiscal 2023. The increase in interest expense was principally due to an increase in the amount of outstanding debt related to fiscal 2023 acquisitions.

Other Income

Other income in the first quarter of fiscal 2024 and 2023 was not material.

Index

Income Tax Expense

Our effective tax rate decreased to 11.8% in the first quarter of fiscal 2024, down from 16.9% in the first quarter of fiscal 2023. The decrease in our effective tax rate principally reflects a larger tax benefit from stock option exercises recognized in the first quarter of fiscal 2024. We recognized a discrete tax benefit from stock option exercises in both the first quarter of fiscal 2024 and 2023 of $13.6 million and $6.2 million, respectively.

Net Income Attributable to Noncontrolling Interests

Net income attributable to noncontrolling interests relates to the 20% noncontrolling interest held by Lufthansa Technik AG in HEICO Aerospace Holdings Corp. and the noncontrolling interests held by others in certain subsidiaries of the FSG and ETG. Net income attributable to noncontrolling interests was $10.8 million in the first quarter of fiscal 2024, as compared to $10.0 million in the first quarter of fiscal 2023. The increase in net income attributable to noncontrolling interests principally reflects improved operating results of certain subsidiaries of the FSG and ETG in which noncontrolling interests are held.

Net Income Attributable to HEICO

Net income attributable to HEICO increased by 23% to $114.7 million, or $.82 per diluted share, in the first quarter of fiscal 2024, up from $93.0 million, or $.67 per diluted share, in the first quarter of fiscal 2023 principally reflecting the previously mentioned higher consolidated operating income and lower effective tax rate, partially offset by the previously mentioned higher interest expense.

Outlook

As we look ahead to the remainder of fiscal 2024, we continue to anticipate net sales growth in both the FSG and ETG, principally driven by contributions from our fiscal 2023 acquisitions and demand for the majority of our products. Additionally, we plan to continue our commitment to developing new products and services and further market penetration, while maintaining our financial strength and flexibility.

Index

Liquidity and Capital Resources

Our principal uses of cash include acquisitions, capital expenditures, interest payments, cash dividends, distributions to noncontrolling interests and working capital needs. We continue to anticipate fiscal 2024 capital expenditures to be approximately $65 million. We finance our activities primarily from our operating and financing activities, including borrowings under our revolving credit facility. The revolving credit facility and senior unsecured notes contain both financial and non-financial covenants. As of January 31, 2024, we were in compliance with all such covenants and our total debt to shareholders’ equity ratio was 75.4%.

Based on our current outlook, we believe that net cash provided by operating activities and available borrowings under our revolving credit facility will be sufficient to fund our cash requirements for at least the next twelve months.

Operating Activities

Net cash provided by operating activities was $111.7 million in the first quarter of fiscal 2024 and consisted primarily of net income from consolidated operations of $125.5 million, depreciation and amortization expense of $43.5 million (a non-cash item), and net changes in other long-term liabilities and assets related to the LCP of $14.8 million (principally participant deferrals and employer contributions), partially offset by a $71.8 million increase in net working capital. The increase in net working capital is inclusive of a $50.5 million decrease in accrued expenses and other current liabilities mainly reflecting the payment of fiscal 2023 accrued performance-based compensation, a $49.8 million increase in inventories to support an increase in consolidated backlog, and a $15.8 million increase in prepaid expenses and other current assets, partially offset by a $38.9 million decrease in accounts receivable resulting from the timing of collections.

Net cash provided by operating activities increased by $35.0 million in the first quarter of fiscal 2024, up from $76.7 million in the first quarter of fiscal 2023. The increase is principally attributable to a $22.5 million increase in net income from consolidated operations and a $16.4 million increase in depreciation and amortization expense.

Investing Activities

Net cash used in investing activities totaled $71.1 million in the first quarter of fiscal 2024 and related primarily to acquisitions of $46.2 million, capital expenditures of $13.4 million and investments related to the LCP of $12.7 million. Further details regarding our fiscal 2024 acquisition may be found in Note 2, Acquisition, of the Notes to Condensed Consolidated Financial Statements.

Index

Financing Activities

Net cash used in financing activities in the first quarter of fiscal 2024 totaled $16.7 million. During the first quarter of fiscal 2024, we borrowed $50.0 million under our revolving credit facility, which was partially offset by $15.0 million in payments made on our revolving credit facility, $13.9 million of net payments on short-term debt, $13.8 million of cash dividends paid on our common stock, $13.8 million of contingent consideration payments and $8.8 million of distributions to noncontrolling interests.

Other Obligations and Commitments

There have not been any material changes to our other obligations and commitments that were included in our Annual Report on Form 10-K for the year ended October 31, 2023.

New Accounting Pronouncements

See Note 1, Summary of Significant Accounting Policies - New Accounting Pronouncements, of the Notes to Condensed Consolidated Financial Statements for additional information.

Guarantor Group Summarized Financial Information

On July 27, 2023, we completed the public offer and sale of senior unsecured notes, which consisted of $600 million principal amount of 5.25% Senior Notes due August 1, 2028 (the "2028 Notes") and $600 million principal amount of 5.35% Senior Notes due August 1, 2033 (the "2033 Notes" and, collectively with the 2028 Notes, the "Notes"). The Notes are fully and unconditionally guaranteed on a senior unsecured basis by all of our existing and future subsidiaries that guarantee our obligations under our revolving credit facility ("Credit Facility") (the “Guarantor Group”).

The Notes were issued pursuant to an Indenture, dated as of July 27, 2023 (the “Base Indenture”), between HEICO and certain of its subsidiaries (collectively, the "Subsidiary Guarantors") and Truist Bank, as trustee (the “Trustee”), as supplemented by a First Supplemental Indenture, dated as of July 27, 2023 (the “First Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between us, the Subsidiary Guarantors and the Trustee. The Notes are direct, unsecured senior obligations of HEICO and rank equally in right of payment with all of our existing and future senior unsecured indebtedness. Each Subsidiary Guarantor is owned either directly or indirectly by the Company and jointly and severally guarantee our obligations under the Notes. None of the Subsidiary Guarantors are organized outside of the U.S.

Index

Under the Indenture, holders of the Notes will be deemed to have consented to the release of a subsidiary guarantee provided by a subsidiary guarantor, without any action required on the part of the Trustee or any holder of the Notes, upon such subsidiary guarantor ceasing to guarantee or to be an obligor with respect to the Credit Facility. Accordingly, if the lenders under the Credit Facility release a subsidiary guarantor from its guarantee of, or obligations as a borrower under, the Credit Facility, the obligations of the subsidiary guarantors to guarantee the Notes will immediately terminate. If any of our future subsidiaries incur obligations under the Credit Facility while the Notes are outstanding, then such subsidiary will be required to guarantee the Notes.

In addition, a subsidiary guarantor will be released and relieved from all its obligations under its subsidiary guarantee in the following circumstances, each of which is permitted by the indenture:

•upon the sale or other disposition (including by way of consolidation or merger), in one transaction or a series of related transactions, of a majority of the total voting stock of such subsidiary guarantor (other than to us or any of our affiliates); or

•upon the sale or disposition of all or substantially all the property of such subsidiary guarantor (other than to any of our affiliates or another subsidiary guarantor);

provided, however, that, in each case, such transaction is permitted by the Credit Facility and after giving effect to such transaction, such subsidiary guarantor is no longer liable for any subsidiary guarantee or other obligations in respect of the Credit Facility. The subsidiary guarantee of a subsidiary guarantor also will be released if we exercise our legal defeasance, covenant defeasance option or discharge the Indenture.

We conduct our operations almost entirely through our subsidiaries. Accordingly, the Guarantor Group’s cash flow and ability to service any guaranteed registered debt securities will depend on the earnings of our subsidiaries and the distribution of those earnings to the Guarantor Group, including the earnings of the non-guarantor subsidiaries, whether by dividends, loans or otherwise. Holders of the guaranteed registered debt securities will have a direct claim only against the Guarantor Group.

The following tables include summarized financial information for the Guarantor Group (in thousands). The information for the Guarantor Group is presented on a combined basis, excluding intercompany balances and transactions between us and the Guarantor Group and excluding investments in and equity in the earnings of non-guarantor subsidiaries. The Guarantor Group’s amounts due from, amounts due to, and transactions with non-guarantor subsidiaries have been presented in separate line items. The consolidating schedules are provided in accordance with the reporting requirements of Rule 13-01 under SEC Regulation S-X for the issuer and guarantor subsidiaries.

•The severity, magnitude and duration of public health threats, such as the COVID-19 pandemic;

•Our liquidity and the amount and timing of cash generation;

•Lower commercial air travel, airline fleet changes or airline purchasing decisions, 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, space or homeland security spending by U.S. and/or foreign customers or competition from existing and new competitors, which could reduce our sales;

•Our ability to introduce new products and services at profitable pricing levels, which could reduce our sales or sales growth;

•Product development or manufacturing difficulties, which could increase our product development and manufacturing costs and delay sales; and

•Our ability to make acquisitions, including obtaining any applicable domestic and/or foreign governmental approvals, and achieve operating synergies from acquired businesses; customer credit risk; interest, foreign currency exchange and income tax rates; and economic conditions, including the effects of inflation, within and outside of the aviation, defense, space, medical, telecommunications and electronics industries, which could negatively impact our costs and revenues.

We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by applicable law.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Jan. 31, 2024
Accounting Policies [Abstract]
Summary of Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited condensed consolidated financial statements of HEICO Corporation and its subsidiaries (collectively, “HEICO,” or 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, 2023. The October 31, 2023 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, statements of comprehensive income, statements of shareholders' equity and statements of cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2024 are not necessarily indicative of the results which may be expected for the entire fiscal year. The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. ("HFSC") and their respective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. and its subsidiaries. New Accounting Pronouncements In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. The ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment performance and deciding how to allocate resources. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, or in fiscal 2025 for HEICO, and interim periods within fiscal years beginning one year later. Early adoption is permitted and the amendments must be applied retrospectively to all prior periods presented. The adoption of this guidance will not affect the Company's consolidated results of operations, financial position or cash flows and the Company is currently evaluating the effect the guidance will have on its disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of specific categories in the annual effective tax rate reconciliation table and further disaggregation for reconciling items that meet a quantitative threshold. The ASU also requires the disaggregation of income taxes paid by jurisdiction. ASU 2023-09 may be applied either prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2024, or in fiscal 2026 for HEICO. Early adoption is permitted. The adoption of this guidance will not affect the Company's consolidated results of operations, financial position or cash flows and the Company is currently evaluating the effect the guidance will have on its disclosures.

ACQUISITIONS	Jan. 31, 2024
Business Combination and Asset Acquisition [Abstract]
Asset Acquisition	ACQUISITION In December 2023, the Company, through a subsidiary of HFSC, entered into an exclusive license and acquired certain assets for the capability to support the Boeing 737NG/777 Cockpit Display and Legacy Displays product lines from Honeywell International. The transaction provides the HFSC subsidiary with the exclusive capability to produce, sell, and repair Boeing 737NG/777 Cockpit Displays as well as other Legacy Displays for Boeing 717, ATR, and select business and general aviation aircraft. The purchase price of this acquisition was paid in cash using proceeds from the Company's revolving credit facility, and is not material or significant to the Company's condensed consolidated financial statements. The allocation of the total consideration for this acquisition to the tangible and identifiable intangible assets acquired is preliminary until the Company obtains final information regarding their fair values. However, the Company does not expect any adjustment to such allocation to be material to the Company's consolidated financial statements. This acquisition’s operating results were included in the Company’s results of operations from the effective acquisition date. The amount of net sales and earnings of this acquisition included in the Condensed Consolidated Statement of Operations for the three months ended January 31, 2024 is not material. Had this acquisition occurred as of November 1, 2022, net sales, net income from consolidated operations, net income attributable to HEICO, and basic and diluted net income per share attributable to HEICO shareholders on a pro forma basis for the three months ended January 31, 2024 and 2023 would not have been materially different than the reported amounts.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Jan. 31, 2024
Accounting Policies [Abstract]
Basis of Presentation [Text Block]	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of HEICO Corporation and its subsidiaries (collectively, “HEICO,” or 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, 2023. The October 31, 2023 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, statements of comprehensive income, statements of shareholders' equity and statements of cash flows for such interim periods presented. The results of operations for the three months ended January 31, 2024 are not necessarily indicative of the results which may be expected for the entire fiscal year. The Company has two operating segments: the Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. ("HFSC") and their respective subsidiaries; and the Electronic Technologies Group (“ETG”), consisting of HEICO Electronic Technologies Corp. and its subsidiaries.
New Accounting Pronouncements, Policy [Policy Text Block]	New Accounting Pronouncements In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which expands reportable segment disclosure requirements by requiring disclosures of significant reportable segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and included within each reported measure of a segment's profit or loss. The ASU also requires disclosure of the title and position of the individual identified as the CODM and an explanation of how the CODM uses the reported measures of a segment's profit or loss in assessing segment performance and deciding how to allocate resources. Additionally, ASU 2023-07 requires all segment profit or loss and assets disclosures to be provided on an annual and interim basis. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, or in fiscal 2025 for HEICO, and interim periods within fiscal years beginning one year later. Early adoption is permitted and the amendments must be applied retrospectively to all prior periods presented. The adoption of this guidance will not affect the Company's consolidated results of operations, financial position or cash flows and the Company is currently evaluating the effect the guidance will have on its disclosures. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires disclosure of specific categories in the annual effective tax rate reconciliation table and further disaggregation for reconciling items that meet a quantitative threshold. The ASU also requires the disaggregation of income taxes paid by jurisdiction. ASU 2023-09 may be applied either prospectively or retrospectively and is effective for fiscal years beginning after December 15, 2024, or in fiscal 2026 for HEICO. Early adoption is permitted. The adoption of this guidance will not affect the Company's consolidated results of operations, financial position or cash flows and the Company is currently evaluating the effect the guidance will have on its disclosures.
