EXHIBIT 99.1 February 25, 2026 Victor H. Mendelson (305) 374-1745 ext. 7590 Carlos L. Macau, Jr. (954) 987-4000 ext. 7570 HEICO CORPORATION REPORTS RECORD NET INCOME (UP 13%) AND STRONG INCREASES IN OPERATING INCOME (UP 15%) AND NET SALES (UP 14%) FOR THE FIRST QUARTER OF FISCAL 2026 HOLLYWOOD, FL and MIAMI, FL -- HEICO CORPORATION (NYSE: HEI.A) (NYSE: HEI) today reported an increase in net income of 13% to a record $190.2 million, or $1.35 per diluted share, in the first quarter of fiscal 2026, up from $168.0 million, or $1.20 per diluted share, in the first quarter of fiscal 2025. Net sales increased 14% to $1,178.6 million in the first quarter of fiscal 2026, up from $1,030.2 million in the first quarter of fiscal 2025. Operating income increased 15% to $259.9 million in the first quarter of fiscal 2026, up from $226.8 million in the first quarter of fiscal 2025. The Company's consolidated operating margin improved to 22.1% in the first quarter of fiscal 2026, up from 22.0% in the first quarter of fiscal 2025. EBITDA increased 14% to $312.0 million in the first quarter of fiscal 2026, up from $273.9 million in the first quarter of fiscal 2025. See our reconciliation of net income attributable to HEICO to EBITDA at the end of this press release. Net income attributable to HEICO in the first quarter of fiscal 2026 and 2025 were both favorably impacted by a discrete income tax benefit from stock option exercises. The benefit in the first quarter of fiscal 2026, net of noncontrolling interests, was $21.8 million, or 15 cents per diluted share, as compared to $26.5 million, or 19 cents per diluted share, in the first quarter of fiscal 2025. Consolidated Results Eric A. Mendelson and Victor H. Mendelson, HEICO’s Co-Chairmen and Co-Chief Executive Officers, commented on the Company's first quarter results stating, "We are proud to report record quarterly net income, as well as increased operating income and net sales, principally driven by strong double-digit consolidated organic net sales growth, as well as the contributions from our fiscal 2025 and 2026 acquisitions. The strong organic growth reflects increased demand across all of the Flight Support Group’s product lines and for the Electronic Technologies Group's other electronics, aerospace and defense products. -more- Cash flow provided by operating activities remained strong, totaling $178.6 million in the first quarter of fiscal 2026, as compared to $203.0 million in the first quarter of fiscal 2025. The decrease in cash provided by operating activities reflects a significant distribution to a certain participant under the HEICO Leadership Compensation Plan, as well as higher performance-based compensation payments driven by strong operating performance across both segments in fiscal 2025. We continue to forecast strong cash flow from operations for fiscal 2026. Our total debt to net income attributable to HEICO ratio was 3.52x as of January 31, 2026, as compared to 3.14x as of October 31, 2025. Our net debt to EBITDA ratio was 1.79x as of January 31, 2026, as compared to 1.60x as of October 31, 2025. The increase in our leverage ratio in the first quarter of fiscal 2026 is a direct result of the successful completion of an acquisition during the quarter. See our reconciliation of total debt to net debt at the end of this press release. As we look ahead to the remainder of fiscal 2026, we expect continued sales momentum across both the Flight Support Group and the Electronic Technologies Group, supported by organic demand for our products, together with the impact of recent acquisitions. We remain focused on pursuing selective acquisition opportunities that align with our growth strategy. Our disciplined financial management continues to emphasize long-term shareholder value through a combination of strategic acquisitions and organic growth, while preserving financial strength and flexibility." Flight Support Group The Flight Support Group delivered strong results in operating income and net sales, achieving quarterly increases of 21% and 15%, respectively, as compared to the first quarter of fiscal 2025. These exceptional results reflect strong double-digit organic net sales growth, driven by increased demand across all of the Flight Support Group's product lines, as well as the contributions from our fiscal 2025 acquisitions. The Flight Support Group's net sales increased 15% to $820.0 million in the first quarter of fiscal 2026, up from $713.2 million in the first quarter of fiscal 2025. The net sales increase stems from strong organic growth of 12% and the impact from our fiscal 2025 acquisitions. The organic net sales growth is attributable to increased demand across all of the Flight Support Group’s product lines. The Flight Support Group's operating income increased 21% to $200.7 million in the first quarter of fiscal 2026, up from $166.1 million in the first quarter of fiscal 2025. The operating income increase was principally driven by the previously mentioned net sales growth, selling, general and administrative ("SG&A") expense efficiencies realized from the net sales growth, and an improved gross profit margin. The improved gross profit margin principally reflects the previously mentioned higher net sales and a more favorable product mix within our repair and overhaul parts and services product line. -more- The Flight Support Group's operating margin improved to 24.5% in the first quarter of fiscal 2026, up from 23.3% in the first quarter of fiscal 2025. The increased operating margin principally reflects a decrease in SG&A expenses as a percentage of net sales, mainly reflecting the previously mentioned SG&A expense efficiencies and improved gross profit margin. Electronic Technologies Group The Electronic Technologies Group's first quarter 12% net sales increase was driven mainly by strong organic growth across most of our products, with double-digit organic net sales growth for our aerospace and other electronics products. The Electronic Technologies Group's net sales increased 12% to $370.7 million in the first quarter of fiscal 2026, up from $330.3 million in the first quarter of fiscal 2025. The net sales increase was driven by strong organic growth of 6% and the impact from our fiscal 2025 and 2026 acquisitions. The organic net sales growth is mainly attributable to increased demand for our other electronics, aerospace and defense products, partially offset by a decrease in demand for our space products. The Electronic Technologies Group's operating income was $73.2 million in the first quarter of fiscal 2026, as compared to $76.5 million in the first quarter of fiscal 2025. The operating income decrease principally reflects a decrease in gross profit margin, partially offset by the previously mentioned net sales growth. The decrease in gross profit margin principally resulted from a less favorable product mix of defense products and the previously mentioned decrease in net sales of space products, partially offset by the previously mentioned increase in net sales of aerospace products. The Electronic Technologies Group's operating margin was 19.8% in the first quarter of fiscal 2026, as compared to 23.1% in the first quarter of fiscal 2025. The decreased operating margin principally reflects the previously mentioned lower gross profit margin. Non-GAAP Financial Measures To provide additional information about the Company's results, HEICO has discussed in this press release its EBITDA (calculated as net income attributable to HEICO adjusted for depreciation and amortization expense, net income attributable to noncontrolling interests, interest expense and income tax expense), its net debt (calculated as total debt less cash and cash equivalents), and its net debt to EBITDA ratio (calculated as net debt divided by EBITDA), which are not prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). These non-GAAP measures are included to supplement the Company’s financial information presented in accordance with GAAP and because the Company uses such measures to monitor and evaluate the performance of its business and believes the presentation of these measures enhance an investor's ability to analyze trends in the -more- Company’s business and to evaluate the Company’s performance relative to other companies in its industry. However, these non-GAAP measures have limitations and should not be considered in isolation or as a substitute for analysis of the Company's financial results as reported under GAAP. These non-GAAP measures are not in accordance with, or an alternative to, measures prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. These measures should only be used to evaluate the Company's results of operations in conjunction with their corresponding GAAP measures. Pursuant to the requirements of Regulation G of the Securities and Exchange Act of 1934, the Company has provided a reconciliation of these non-GAAP measures in the last table included in this press release.
