HEICO CORP

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.

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.

The Electronic Technologies Group . Our Electronic Technologies Group ("ETG"), consisting of HEICO Electronic Technologies Corp. and its subsidiaries, accounted for 30%, 32% and 40% of our net sales in fiscal 2025, 2024 and 2023, respectively. The ETG derived approximately 51%, 51% and 49% of its net sales in fiscal 2025, 2024 and 2023, respectively, from the sale of products and services to U.S. and foreign military agencies, prime defense contractors and both commercial and defense satellite and spacecraft manufacturers. The ETG collectively designs, manufactures and sells various types of electronic, data and microwave, and electro-optical products, including infrared simulation and test equipment, laser rangefinder receivers, electrical power supplies, back-up power supplies, power conversion products, underwater locator beacons, emergency locator transmission beacons, flight deck annunciators, panels, indicators, electromagnetic and radio frequency interference shielding and filters, high power capacitor charging power supplies, amplifiers, traveling wave tube amplifiers, photodetectors, amplifier modules, microwave power modules, flash lamp drivers, laser diode drivers, arc lamp power supplies, custom power supply designs, cable assemblies, high voltage power supplies, high voltage interconnection devices and wire, high voltage energy generators, high frequency power delivery systems; memory products, including three-dimensional microelectronic and stacked memory, static random-access memory (SRAM), and electronically erasable programmable read-only memory (EEPROM); harsh environment electronic connectors and other interconnect products, radio frequency ("RF") and microwave amplifiers, transmitters, and receivers and integrated assemblies, sub-assemblies and components; RF sources, detectors and controllers, wireless cabin control systems, solid state power distribution and management systems, proprietary in-cabin power and entertainment components and subsystems, cockpit displays and other avionics components, crashworthy and ballistically self-sealing auxiliary fuel systems, nuclear radiation detectors, communications and electronic intercept receivers and tuners, fuel level sensing systems, high-speed interface products that link devices, high performance active antenna systems and airborne antennas for commercial and military aircraft, precision guided munitions, other defense applications and commercial uses; silicone material for a variety of demanding applications; precision power analog monolithic, hybrid and open frame components; high-reliability ceramic-to-metal feedthroughs and connectors, technical surveillance countermeasures (TSCM) equipment to detect devices used for espionage and information theft; rugged small-form factor embed
