HEICO CORPORATION

HEICO Corporation has two classes of common stock, Common Stock and Class A Common Stock, both listed on the New York Stock Exchange. Beneficial ownership of 5% or more of either class is disclosed in the company’s proxy statement filed with the U.S. Securities and Exchange Commission. As of the 17 January 2025 record date used in HEICO Corporation’s most recent annual meeting proxy statement, the largest disclosed holder was the Mendelson Reporting Group, a group comprising members of the Mendelson family together with related trusts and entities, reporting beneficial ownership of approximately 16.54% of Common Stock and 1.17% of Class A Common Stock.

Other beneficial owners of 5% or more disclosed in the same filing included The Vanguard Group, Inc. (approximately 6.58% of Common Stock and 9.56% of Class A Common Stock), BlackRock, Inc. (approximately 9.08% of Common Stock and 6.34% of Class A Common Stock), Capital World Investors (approximately 7.44% of Common Stock), Dr. Herbert A. Wertheim (approximately 7.47% of Common Stock and 7.78% of Class A Common Stock), Principal Global Investors, LLC (approximately 11.66% of Class A Common Stock) and FMR LLC (approximately 5.90% of Class A Common Stock). These figures represent institutional and reportable beneficial ownership rather than a complete shareholder register; as a U.S. publicly traded company, HEICO Corporation is not required to disclose its full shareholder base.

The Mendelson Reporting Group’s filing identifies Laurans A. Mendelson, Eric A. Mendelson and Victor H. Mendelson, together with related family entities, as members of the reporting group, without attributing a separately calculated percentage to each individual member. Laurans A. Mendelson died on 27 September 2025; the public filings reviewed for this profile have not yet updated the Mendelson Reporting Group’s disclosed holding to reflect any resulting change in beneficial ownership, so the percentages above should be read as of the January 2025 record date rather than as current.

Shareholder disclosure for HEICO Corporation is best described as major shareholders only: only holders crossing the 5% SEC reporting threshold are individually named, and no complete shareholder register is publicly available. No single ultimate beneficial owner or calculated UBO percentage can be reliably established from the available filings, because the Mendelson Reporting Group’s holding is disclosed collectively rather than attributed to one individual.

HEICO Corporation’s board of directors and executive leadership are disclosed in its filings with the U.S. Securities and Exchange Commission and on its official website. Following the death of Executive Chairman Laurans A. Mendelson on 27 September 2025, his sons Eric A. Mendelson and Victor H. Mendelson were named Co-Chairmen of the Board of Directors; both had already been serving as Co-Chief Executive Officers since 1 May 2025, alongside their existing roles as President and Chief Executive Officer of the Flight Support Group (Eric A. Mendelson, since 1993) and of the Electronic Technologies Group (Victor H. Mendelson, since 1996). The board also includes independent directors Thomas M. Culligan, Carol F. Fine, Adolfo Henriques, Mark H. Hildebrandt, Julie Neitzel and Dr. Alan Schriesheim.

Among named executive officers, Carlos L. Macau, Jr. has served as Executive Vice President, Chief Financial Officer and Treasurer since June 2012, and Steven M. Walker has served as Chief Accounting Officer since June 2012. Nationality is not disclosed for HEICO Corporation’s directors or officers in its SEC filings or on its corporate website, and country of residence is likewise not separately stated in those sources. Any address on file with the Florida Department of State relates to the company’s registered office and agent for service of process, and should not be read as an individual officer’s residence.

Recent officer changes: Laurans A. Mendelson transitioned from Chairman and Chief Executive Officer to Executive Chairman effective 1 May 2025, with Eric A. Mendelson and Victor H. Mendelson becoming Co-Chief Executive Officers on the same date; following Laurans A. Mendelson’s death on 27 September 2025, Eric A. Mendelson and Victor H. Mendelson were named Co-Chairmen of the Board of Directors.

Officer and director information for HEICO Corporation is best described as current only, based on the company’s most recent proxy statement, 8-K filings and official board of directors page; full historical appointment and resignation dates for every director are not itemized in the sources reviewed.

HEICO Corporation is the ultimate parent company of its corporate group; it is not a subsidiary of any other entity. The company operates through two principal segments, the Flight Support Group and the Electronic Technologies Group, each comprising numerous directly and indirectly held subsidiaries incorporated primarily in the United States, together with certain subsidiaries in France, the United Kingdom, Singapore, Hong Kong, Mexico, Canada, India and other countries.

Two of the group’s most significant subsidiaries were acquired through verified, publicly announced transactions. In January 2023, HEICO Corporation, through its Electronic Technologies Group, acquired approximately 93.69% of the outstanding common stock and all preferred stock of Exxelia International SAS, a France-registered manufacturer of passive electronic components, for approximately $504 million in net cash. In August 2023, HEICO Corporation completed the acquisition of Wencor Group, LLC, a U.S. aircraft aftermarket parts and repair business, for approximately $2.05 billion in cash and HEICO Class A Common Stock, the largest acquisition in the company’s history, which was integrated into the Flight Support Group.

Beyond these two verified transactions, HEICO Corporation’s SEC filings and official disclosures do not itemize ownership percentages, voting control or the individual parent/subsidiary status of the numerous smaller operating entities within its corporate structure. Group and subsidiary information for HEICO Corporation is best described as partial: the identity of its major, recently acquired subsidiaries is independently verifiable through official acquisition announcements and SEC filings, but ownership percentages and status for the group’s full population of smaller subsidiaries are not independently confirmed beyond what already appears in the company’s registry-sourced corporate-structure data.
