HEICO Corporation (NYSE: HEI) is a leading supplier of aircraft aftermarket parts and maintenance, repair, and overhaul (MRO) services, with a long track record of growth driven by disciplined acquisitions and organic reinvestment in a fragmented industry. Originally founded as Heinicke Instruments in 1957, the company transitioned into aerospace and has since completed over 110 acquisitions, building a diversified platform across commercial, defense, and business aviation markets.

Its operations are split between the Flight Support Group (FSG), which contributes roughly 70% of revenue and focuses on aftermarket parts and MRO services, and the Electronic Technologies Group (ETG), which provides mission-critical components for defense and space applications. HEICO is well positioned to benefit from a structural supply-demand imbalance in the aviation industry, where global aircraft production remains significantly below replacement needs, with a shortfall expected to persist into the early 2030s.
This dynamic is driving increased utilization of aging aircraft, supporting sustained demand for aftermarket parts and MRO services. The company’s expanding catalog of FAA-approved parts and ability to pass through rising input costs further reinforces its margin resilience and pricing power.
Recent financial performance reflects this favorable backdrop, with strong revenue growth led by FSG, alongside margin expansion, while temporary pressure in ETG margins is expected to normalize through the fiscal year. HEICO continues to execute on its acquisition strategy, recently adding capabilities across fuel systems and turbine components, further broadening its addressable market. Overall, the company presents a compelling long-term growth story supported by durable industry tailwinds, strong competitive positioning, and consistent execution.
