See our reconciliation of net income attributable to HEICO to EBITDA at the end of this press release. -more- Consolidated Results Laurans A. Mendelson, HEICO’s Executive Chairman, along with Co-Chief Executive Officers Eric A. Mendelson and Victor H. Mendelson, commented on the Company's second quarter results stating, "We are very pleased to report record quarterly operating income and net sales, driven primarily by double-digit consolidated organic net sales growth. This performance mainly reflects strong organic net sales growth across all product lines of the Flight Support Group and double-digit organic net sales growth for the Electronic Technologies Group’s space and aerospace products. Cash flow provided by operating activities increased 45% to $204.7 million in the second quarter of fiscal 2025, up from $141.1 million in the second quarter of fiscal 2024. We continue to forecast strong cash flow from operations for fiscal 2025. Our total debt to net income attributable to HEICO ratio was 3.79x as of April 30, 2025, down from 4.34x as of October 31, 2024. Our net debt to EBITDA ratio was 1.86x as of April 30, 2025, down from 2.06x as of October 31, 2024. 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 2025, we remain confident in achieving net sales growth across both the Flight Support Group and Electronic Technologies Group segments, driven primarily by strong organic demand for most of our products. Additionally, we aim to accelerate growth through our recently completed acquisitions while positioning ourselves to capitalize on future acquisition opportunities. Our disciplined financial strategy continues to focus on maximizing long-term shareholder value through a balanced approach of strategic acquisitions and organic growth initiatives aimed at gaining market share, while maintaining a strong financial position and preserving flexibility." Flight Support Group Noting the Flight Support Group's record setting second quarter results, the Company stated that it extended its growth trend and achieved quarterly increases of 24% and 19% in operating income and net sales, respectively, as compared to the second quarter of fiscal 2024. These exceptional results principally reflect robust 14% quarterly organic net sales growth driven by increased demand across all of Flight Support Group's product lines, as well as the contributions from the fiscal 2025 and 2024 acquisitions. The Flight Support Group has now achieved nineteen consecutive quarters of growth in net sales. The Flight Support Group's net sales increased 19% to a record $767.1 million in the second quarter of fiscal 2025, up from $647.2 million in the second quarter of fiscal 2024. The Flight Support Group's net sales increased 17% to a record $1,480.2 million in the first six months of fiscal 2025, up from $1,265.9 million in the first six months of fiscal 2024. The net sales increase in the second quarter and first six months of fiscal -more- 2025 reflects strong organic growth of 14% and the impact from our fiscal 2025 and 2024 acquisitions. The organic net sales growth in the second quarter and first six months of fiscal 2025 reflects increased demand across all of our product lines. The Flight Support Group's operating income increased 24% to a record $185.0 million in the second quarter of fiscal 2025, up from $148.9 million in the second quarter of fiscal 2024. The operating income increase principally reflects the previously mentioned net sales growth and an improved gross profit margin, partially offset by the impact from changes in the estimated fair value of accrued contingent consideration. The improved gross profit margin principally reflects higher net sales within our repair and overhaul parts and services product line and higher net sales and a more favorable mix of defense products within our specialty products product line. The Flight Support Group's operating income increased 23% to a record $351.1 million in the first six months of fiscal 2025, up from $285.0 million in the first six months of fiscal 2024. The operating income increase principally reflects the previously mentioned net sales growth, an improved gross profit margin, and selling, general and administrative ("SG&A") expense efficiencies realized from the net sales growth, partially offset by the impact from changes in estimated fair value of accrued contingent consideration. The improved gross profit margin principally reflects the higher net sales across all of our product lines and a more favorable mix of defense products within our specialty products product line. The Flight Support Group's operating margin improved to 24.1% in the second quarter of fiscal 2025, up from 23.0% in the second quarter of fiscal 2024. The operating margin increase principally reflects the previously mentioned improved gross profit margin, partially offset by the impact from the previously mentioned changes in the estimated fair value of accrued contingent consideration. The Flight Support Group's operating margin improved to 23.7% in the first six months of fiscal 2025, up from 22.5% in the first six months of fiscal 2024. The operating margin increase principally reflects the previously mentioned improved gross profit margin. Electronic Technologies Group With respect to the Electronic Technologies Group's strong second quarter results the Company credited improved demand for the majority of its products, including strong double-digit organic net sales growth for the Electronic Technologies Group's space and aerospace products, which contributed favorably to the quarterly results. The Electronic Technologies Group's net sales increased 7% to $342.2 million in the second quarter of fiscal 2025, up from $319.3 million in the second quarter of fiscal 2024. The net sales increase reflects organic growth of 4% and the impact from our fiscal 2024 and 2025 acquisitions. The organic net sales growth is mainly attributable to -more- increased demand for our space, aerospace, and other electronics products, partially offset by a decrease in demand for our medical and defense products. The Electronic Technologies Group's net sales increased 11% to a record $672.5 million in the first six months of fiscal 2025, up from $605.3 million in the first six months of fiscal 2024. The net sales increase reflects strong organic growth of 7% and the impact from our fiscal 2024 and 2025 acquisitions. The organic net sales growth mainly reflects increased demand for our space, defense, and aerospace products, partially offset by a decrease in demand for our medical products. The Electronic Technologies Group's operating income increased 3% to $77.9 million in the second quarter of fiscal 2025, up from $75.3 million in the second quarter of fiscal 2024. The operating income increase principally reflects the previously mentioned net sales growth and SG&A expense efficiencies realized from the net sales growth, partially offset by a lower gross profit margin. The lower gross profit margin principally reflects the decreased defense and medical products net sales, partially offset by the increased space products net sales. The Electronic Technologies Group's operating income increased 18% to a record $154.3 million in the first six months of fiscal 2025, up from $130.6 million in the first six months of fiscal 2024. The operating income increase principally reflects the previously mentioned net sales growth and SG&A expense efficiencies realized from the increased net sales. The Electronic Technologies Group's operating margin was 22.8% in the second quarter of fiscal 2025, as compared to 23.6% in the second quarter of fiscal 2024. The lower operating margin principally reflects the previously mentioned lower gross profit margin, partially offset by a decrease in SG&A expenses as a percentage of net sales, mainly due to the previously mentioned efficiencies. The Electronic Technologies Group's operating margin improved to 23.0% in the first six months of fiscal 2025, up from 21.6% in the first six months of fiscal 2024. The increased operating margin principally reflects lower SG&A expenses as a percentage of net sales, mainly due to the previously mentioned efficiencies. 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”). -more- 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 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.
