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 $364.2 million as of July 31, 2025 and $315.0 million as of October 31, 2024.

As part of the agreement to acquire 90% of the membership interests of a subsidiary by the FSG in fiscal 2025, the Company may be obligated to pay contingent consideration of up to $21.1 million in fiscal 2028 based on the earnings of the acquired entity during the three-year period following the acquisition provided the entity meets a certain earnings objective over the same three-year period. As of July 31, 2025, the estimated fair value of the contingent consideration was $12.1 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. As of July 31, 2025, the estimated fair value of the contingent consideration was $21.5 million.

As part of the agreement to acquire 74% of the membership interests of a subsidiary by the FSG in fiscal 2022, the Company may be obligated to pay contingent consideration of $14.1 million in fiscal 2027 should the acquired entity meet a certain earnings objective during the five-year period following the acquisition. Based on actual results to date and an improving net sales forecast for the subsidiary's products over the remainder of the earnout period, the estimated fair value of the contingent consideration increased from $0.0 million as of October 31, 2024 to $8.6 million as of July 31, 2025.

As part of the agreement to acquire 89.99% of the equity interests of a subsidiary by the ETG in fiscal 2020, the Company paid contingent consideration of CAD $11.7 million, or $8.1 million, in January 2025 as the acquired entity met certain earnings objectives during fiscal 2023 and 2024.

The estimated fair values of the contingent consideration arrangements described above are classified within Level 3 and were determined using a probability-based scenario analysis approach. Under this method, a set of discrete potential future subsidiary earnings was determined using internal estimates based on various revenue growth rate assumptions for each scenario. A probability of likelihood was assigned to each discrete potential future earnings estimate and the resultant contingent consideration was calculated. The resulting probability-weighted contingent consideration amounts were discounted using a weighted average discount rate reflecting the credit risk of a market participant.

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, 2025 ($ in thousands):

		Unobservable		Weighted
Acquisition Date	Fair Value	Input	Range	Average (1)
1-31-2025	$12,075	Compound annual revenue growth rate	5% - 22%	17%
		Discount rate	7.2% - 7.2%	7.2%
7-18-2022	21,534	Compound annual revenue growth rate	3% - 9%	7%
		Discount rate	7.7% - 7.7%	7.7%
3-17-2022	8,643	Compound annual revenue growth rate	(2%) - 6%	3%
		Discount rate	7.8% - 7.8%	7.8%

(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, 2025 are as follows (in thousands):

	Liabilities
Balance as of October 31, 2024	$30,207
Contingent consideration related to an acquisition	11,509
Increase in accrued contingent consideration, net	8,974
Payment of contingent consideration	(8,144)
Foreign currency transaction adjustments	(294)
Balance as of July 31, 2025	$42,252

As of July 31, 2025, the Company's contingent consideration balance is included within other long-term liabilities in its Condensed Consolidated Balance Sheet. The Company records changes in accrued contingent consideration and foreign currency transaction adjustments within SG&A expenses in its Condensed Consolidated Statements of Operations.

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, 2025 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, Long-Term Debt, for the estimated fair value of the Company’s senior unsecured notes.
