AAR Corp. (NYSE: AIR) is a U.S.-based aerospace and defense aftermarket services company listed on the NYSE in the United States. Headquartered in Wood Dale, Illinois, in the Chicago area, AAR traces its roots to 1951, was organized in 1955, and has evolved from a logistics-oriented aviation supplier into a diversified platform serving commercial airlines, government operators, MROs, and OEMs. For investors, the company stands out as an independent, scaled aftermarket franchise with a global footprint across more than 20 countries.
AAR’s business is organized around four operating segments: Parts Supply, Repair & Engineering, Integrated Solutions, and Expeditionary Services. Parts Supply includes the purchase, sale, lease, repair, and overhaul of aircraft and engine parts, with a growing emphasis on new-parts distribution. Repair & Engineering covers airframe maintenance, component repair, heavy maintenance, and engineering-related services. Integrated Solutions focuses on broader maintenance and supply chain programs, while Expeditionary Services addresses government and defense customers with sustainment, logistics, and field-support capabilities. This structure gives AAR exposure to both commercial aviation cycles and recurring government demand.
The company’s competitive position is built on its independence from major OEMs, its breadth of services, and its ability to bundle distribution, repair, and software into an integrated offering. That mix strengthens customer stickiness and supports margin expansion as the company shifts toward higher-value activities. AAR also highlights software solutions that support airlines, MROs, and cargo operators, giving it a more differentiated value proposition than a pure distributor or pure maintenance provider.
Recent developments have been material. In January 2026, AAR reported strong fiscal second-quarter results, including 16% sales growth and improved adjusted EBITDA margins, driven by Parts Supply and recent acquisitions. In November 2025, AAR acquired HAECO Americas, substantially expanding its North American heavy-maintenance footprint and reinforcing its Repair & Engineering strategy; the deal also came with multi-year customer contracts worth more than $850 million. AAR also completed the ADI acquisition in Parts Supply and announced the purchase of Aircraft Reconfig Technologies in early 2026. At its May 2026 Investor Day, management reiterated a strategy centered on above-market growth, margin expansion, and disciplined capital allocation.
