AAR Corp. AIR

Company Overview

AAR Corp. is a global provider of aviation services to commercial airlines, governments, and defense customers, operating primarily within the aerospace and defense services industry. The company focuses on aftermarket aviation support rather than aircraft manufacturing, with core activities spanning maintenance, repair, and overhaul (MRO); parts supply; logistics; and integrated fleet support. Its revenue is primarily driven by long-term service contracts with commercial airlines and government entities, including the U.S. Department of Defense.

Founded in 1951, AAR Corp. began as a distributor of surplus aircraft parts and progressively expanded into comprehensive aviation services through organic growth and acquisitions. Over decades, the company evolved into a diversified aviation services provider with a strategic emphasis on recurring revenue, long-term contracts, and technical capabilities that are difficult to replicate. Its positioning is strengthened by scale, regulatory certifications, and deep customer relationships across both commercial and government aviation markets.
