Business Description

The Company HEICO Corporation through its subsidiaries (collectively, “HEICO,” “we,” “us,” “our” or the “Company”) believes it is the world’s largest manufacturer of Federal Aviation Administration (“FAA”)-approved jet engine and aircraft component replacement parts, other than the original equipment manufacturers (“OEMs”) and their subcontractors. HEICO also believes it is a leading manufacturer of various types of electronic equipment for the aviation, defense, space, medical, telecommunications and electronics industries. The Company was originally organized in 1957 as a holding company known as HEICO Corporation. As part of a reorganization completed in 1993, the original holding company (formerly known as HEICO Corporation) was renamed as HEICO Aerospace Corporation and a new holding corporation known as HEICO Corporation was created. The reorganization did not result in any change in the business of the Company, its consolidated assets or liabilities or the relative interests of its shareholders. Our business is comprised of two operating segments: The Flight Support Group . Our Flight Support Group (“FSG”), consisting of HEICO Aerospace Holdings Corp. and HEICO Flight Support Corp. and their collective subsidiaries, accounted for 70%, 68% and 60% of our net sales in fiscal 2025, 2024 and 2023, respectively. The FSG uses proprietary technology to design and manufacture jet engine and aircraft component replacement parts for sale at lower prices than those manufactured by OEMs. These parts are approved by the FAA and are the functional equivalent of parts sold by OEMs. In addition, the FSG repairs, overhauls and distributes jet engine and aircraft components, avionics and instruments for domestic and foreign commercial air carriers and aircraft repair companies as well as military and business aircraft operators. The FSG also manufactures and sells specialty parts as a subcontractor for aerospace and industrial original equipment manufacturers and the United States ("U.S.") government. Additionally, the FSG is a leading supplier, distributor, and integrator of military aircraft parts and support services primarily to the U.S. Department of Defense, defense prime contractors, and foreign military organizations allied with the U.S. Further, the FSG is a leading manufacturer of advanced niche components and complex composite assemblies for commercial aviation, defense and space applications. The FSG also engineers, designs and manufactures thermal insulation blankets and parts as well as removable/reusable insulation systems for aerospace, defense, commercial and industrial applications; manufactures expanded foil mesh for lightning strike protection in fixed and rotary wing aircraft; distributes aviation electrical interconnect products and electromechanical parts; overhauls industrial pumps, motors, and other hydraulic units with a focus on the support of legacy systems for the U.S. Navy; performs tight-tolerance machining, brazing, fabricating and welding services for aerospace, defense and other industrial applications; and manufactures emergency descent devices ("EDDs") and personnel and cargo parachute products. 1 Index The Electronic Technologies Group .
