Income Tax Disclosure [Text Block] INCOME TAXES
The Company's effective tax rate was 18.4% in the first nine months of fiscal 2026, as compared to 16.0% in the first nine months of fiscal 2025. The increase in the Company's effective tax rate principally reflects a smaller tax benefit from stock option exercises recognized in the first quarter of fiscal 2026. The Company recognized a discrete tax benefit from stock option exercises in the first quarter of fiscal 2026 and 2025 of $22.3 million and $27.2 million, respectively.

The Company's effective tax rate was 20.6% in the third quarter of fiscal 2026, as compared to 18.9% in the third quarter of fiscal 2025. The increase in the Company's effective
tax rate principally reflects a smaller favorable impact from tax-exempt unrealized gains recognized in the cash surrender values of life insurance policies related to the HEICO Corporation Leadership Compensation Plan in the third quarter of fiscal 2026 as compared to the third quarter of fiscal 2025.
