SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	9 Months Ended
	Jul. 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 nine months ended July 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. ("HEICO Electronic") 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.

Business Combinations [Abstract]
Acquisitions [Text Block]	ACQUISITIONS 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. In May 2024, the Company, through the same subsidiary of HFSC that completed the above referenced acquisition in December 2023, completed a second arrangement with Honeywell International under which it acquired licenses and certain assets to further enhance the manufacturing of new products, including screens for a military variant of the Boeing 737NG/777 Cockpit Display and Legacy Displays product lines. The purchase price was paid in cash using cash provided by operating activities and is not material or significant to the Company's condensed consolidated financial statements. The allocation of the total consideration for the fiscal 2024 acquisitions 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 allocations to be material to the Company's consolidated financial statements. The operating results of the fiscal 2024 acquisitions were included in the Company’s results of operations as of each effective acquisition date. The amount of net sales and earnings of the fiscal 2024 acquisitions included in the Condensed Consolidated Statements of Operations for the nine and three months ended July 31, 2024, is not material. Had the fiscal 2024 acquisitions 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 nine and three months ended July 31, 2024, and 2023 would not have been materially different from the reported amounts.

Accordingly, the Company acquired the remaining 9.95% equity interest in May 2024. During fiscal 2024, the holders of a 15% noncontrolling equity interest in a subsidiary of the ETG that was acquired in fiscal 2019 exercised their option to cause the Company to purchase their noncontrolling interest over a four-year period ending in fiscal 2027. Accordingly, the Company acquired one-fourth of such interest in March 2024, which increased the Company's ownership interest in the subsidiary to 88.75%. 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 90.05%.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	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 and other long-term liabilities in the Company’s Condensed Consolidated Balance Sheets. Changes in the Company’s contract assets and liabilities for the nine months ended July 31, 2024 are as follows (in thousands): July 31, 2024 October 31, 2023 Change Contract assets, current $104,412 $111,702 ($7,290) Contract liabilities, current 69,727 87,556 (17,829) Contract liabilities, long-term 54,953 — 54,953 Total contract liabilities 124,680 87,556 37,124 Net contract (liabilities) assets ($20,268) $24,146 ($44,414) The decrease in the Company's contract assets during the first nine months of fiscal 2024 principally reflects billings on certain customer contracts in excess of amounts recorded as unbilled receivables on certain other customer contracts using an over-time revenue recognition model, mainly at the ETG. The increase in the Company's total contract liabilities during the first nine months of fiscal 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 nine and three months ended July 31, 2024 that was included in contract liabilities as of the beginning of fiscal 2024 was $51.3 million and $8.4 million, respectively. 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 July 31, 2024, the Company had $1,862.7 million of remaining performance obligations associated with firm contracts pertaining to the majority of the products offered by the FSG and ETG. The Company will recognize net sales as these obligations are satisfied. The Company expects to recognize $542.8 million of this amount during the remainder of fiscal 2024 and $1,319.9 million thereafter, of which a little more than half is expected to occur in fiscal 2025.

Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	INCOME TAXES The Company's effective tax rate decreased to 17.3% in the first nine months of fiscal 2024, down from 19.0% in the first nine months of fiscal 2023. The decrease in the Company's effective tax rate principally reflects a larger tax benefit from stock option exercises recognized in the first quarter of fiscal 2024. The Company 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. Additionally, the decrease in the Company's effective tax rate reflects the prior year unfavorable impact of the portion of acquisition expenses that was not deductible for income tax purposes. The Company's effective tax rate decreased to 18.0% in the third quarter of fiscal 2024, down from 18.4% in the third quarter of fiscal 2023. The decrease in the Company's effective tax rate principally reflects the prior year unfavorable impact of the portion of acquisition expenses that was not deductible for income tax purposes.

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 $307.4 million as of July 31, 2024 and $226.2 million as of October 31, 2023. In connection with a fiscal 2023 acquisition that is part of the FSG, the Company assumed an agreement which may have obligated it to pay contingent consideration of $17.5 million if 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. Both requirements were met as of October 31, 2023. However, payment of the earnout was also predicated on no indication of a significant change with respect to the underlying customer agreement. In the second quarter of fiscal 2024, the customer notified the Company that it intends to reduce its future orders. As a result, the parties to this agreement agreed to settle on a specific contingent consideration amount of $11.0 million. Accordingly, the $17.3 million estimated fair value of the contingent consideration as of October 31, 2023 was reduced to $11.0 million as of April 30, 2024 and paid in the third 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. Based on the fiscal 2024 forecasted earnings of the acquired entity, the Company does not expect that the required earnings objective will be met. Accordingly, the $5.5 million estimated fair value of the contingent consideration as of October 31, 2023 was reversed in the third quarter of fiscal 2024. 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 July 31, 2024, the estimated fair value of the contingent consideration was $21.1 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 July 31, 2024 and October 31, 2023, the Company did not accrue any contingent consideration for this agreement. 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 $9.8 million, in fiscal 2025 should the acquired entity meet certain earnings objectives during fiscal 2023 and 2024. As of July 31, 2024, the estimated fair value of the contingent consideration was CAD $11.2 million, or $8.1 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. The following unobservable inputs were used to derive the estimated fair value of the Company's Level 3 contingent consideration liabilities as of July 31, 2024: Acquisition Fair Value Unobservable Weighted Date (in thousands) Input Range Average (1) 7-18-2022 $21,134 Compound annual revenue growth rate 1% - 11% 6% Discount rate 8.7% - 8.7% 8.7% 8-18-2020 8,119 Compound annual revenue growth rate 11% - 13% 12% Discount rate 9.8% - 9.8% 9.8% (1) Unobservable inputs were weighted by the relative fair value of the contingent consideration liability. Changes in the Company’s contingent consideration liabilities measured at fair value on a recurring basis using unobservable inputs (Level 3) for the nine months ended July 31, 2024 are as follows (in thousands): Liabilities Balance as of October 31, 2023 $71,136 Payment of contingent consideration (31,000) Decrease in accrued contingent consideration, net (10,892) Foreign currency transaction adjustments 9 $29,253 Included in the accompanying Condensed Consolidated Balance Sheet under the following captions: Accrued expenses and other current liabilities $8,119 Other long-term liabilities 21,134 $29,253 The Company records changes in accrued contingent consideration and foreign currency transaction adjustments within SG&A expenses The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, trade accounts payable and accrued expenses and other current liabilities approximate fair value as of July 31, 2024 due to the relatively short maturity of the respective instruments. The carrying amount of borrowings under the Company's credit facility approximates fair value due to its variable interest rate. See Note 5, Short-Term and Long-Term Debt, for the estimated fair value of the Company’s senior unsecured notes. During the third quarter of fiscal 2024, a non-amortizing trade name within the ETG was measured at fair value on a nonrecurring basis, resulting in the recognition of an impairment loss of $6.0 million (see Note 4, Goodwill and Other Intangible Assets). The fair value of this nonfinancial asset as of July 31, 2024, which is classified within Level 3, and the related impairment loss recognized in the third quarter of fiscal 2024 are as follows (in thousands): Carrying Amount Impairment Loss Fair Value (Level 3) Asset: Trade name $7,800 ($6,000) $1,800 The fair value of the trade name was determined using the relief from royalty method, which is an income approach. This method involves applying an asset-specific discount rate to a forecast of cash flows specific to the asset. The following unobservable inputs were used to derive the estimated fair value of the Level 3 trade name as of July 31, 2024: Unobservable Input Rate Discount rate 15.0% Royalty rate 1.0%

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 nine months ended July 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. ("HEICO Electronic") 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.
