Wood Dale, Illinois — AAR CORP. (NYSE: AIR a leading provider of aviation services to commercial and government operators, MROs, and OEMs, announced today it has acquired Aerostrat, a leading long-range maintenance planning software company, for a purchase price of $15 million plus contingent consideration of up to $5 million. The acquisition immediately expands the reach of AAR’s software offerings and the enterprise resource planning system (ERP) capabilities of AAR’s Trax subsidiary.

Aerostrat’s flagship tool, Aerros, provides long-range heavy maintenance planning solutions to operators and MROs, regardless of the maintenance ERP system in use. Today, Aerros supports more than 5,000 aircraft.

Aerros is also highly complementary to Trax’s ERP and line maintenance focused planning applications. Aerros will be available as part of the Trax suite of products and will also continue to be offered separately for use on all ERP platforms.

“This acquisition of Aerostrat marks an important step in AAR’s strategy to advance the next generation of maintenance products and services,” said Andrew Schmidt, Senior Vice President of AAR Digital Services and President of Trax. “By bringing Aerostrat alongside Trax, we create opportunities for further integration and scope expansion for existing Trax customers as well as Aerostrat customers. We are excited about this powerful pairing of solutions.”
