AAR CORP.

AAR CORP. is a global aerospace and defense aftermarket solutions company, providing a comprehensive range of aviation services to commercial and government customers worldwide. Headquartered in Wood Dale, Illinois, USA, the company's mission is to "go above and beyond to provide value-driven aerospace aftermarket solutions to meet the evolving needs of our customers worldwide."

The company operates through four primary segments: Parts Supply, Repair & Engineering, Integrated Solutions, and Expeditionary Services. Its offerings include the sale and leasing of used serviceable engine and airframe parts, distribution of new parts, airframe maintenance, component repair, and overhaul services. AAR also provides fleet management, operation of customer-owned aircraft, supply chain logistics programs, and specialized software solutions such as Trax, Aerostrat, and Airvoyant. The company serves commercial airlines, which constitute its largest customer segment, as well as government and defense markets globally.

Led by Chairman, President, and CEO John M. Holmes, AAR has recently expanded its capabilities and market presence. In April 2026, the company completed the acquisition of Aircraft Reconfig Technologies (ART), enhancing its engineering and certification services, and launched Airvoyant, an AI-driven procurement platform for the aviation industry. AAR also expanded its commercial distribution partnership with Woodward for engine components and secured significant contracts, including a $305 million follow-on C-40A contract for the U.S. Navy and Marine Corps and $450 million in pallet contracts for the U.S. Air Force. In November 2025, AAR acquired HAECO Americas, solidifying its position as a leading MRO provider in North America. The company reported record consolidated sales of $2.8 billion in Fiscal Year 2025.

AAR Acquires Aircraft Reconfig Technologies to Expand Certification Capabilities

Event summary

  • AAR CORP. completed its acquisition of Aircraft Reconfig Technologies (ART) from ZIM Aircraft Cabin Solutions.
  • The acquisition, announced December 17, 2025, was an all-cash transaction valued at $35 million.

What we're watching

Contract Performance
AAR's ability to execute this large, complex contract efficiently will be crucial, as firm-fixed-price agreements leave little margin for error and potential cost overruns.
Competition
The defense logistics market is competitive; future contract renewals will depend on AAR's ability to demonstrate cost-effectiveness and superior service compared to potential rivals.
Fleet Modernization
The U.S. Navy and Marine Corps’ long-term plans for the C-40A fleet, including potential upgrades or replacements, could impact the scope and duration of AAR’s support requirements.

AAR's Q3 Results Show Acceleration Amidst Strategic Acquisitions

Event summary

  • AAR reported Q3 FY2026 sales of $845 million, a 25% increase year-over-year.
  • Adjusted diluted EPS rose 26% to $1.25, driven by organic sales growth of 14%.
  • The company's Parts Supply segment saw a 45% sales increase, with new parts distribution to government customers growing by 36%.

The big picture

AAR's strong Q3 results underscore the continued demand for aftermarket aviation solutions, particularly within the government sector. The company's aggressive acquisition strategy, totaling billions in recent deals, aims to expand its service offerings and market reach, but carries integration risk. AAR's focus on recurring revenue streams, like Trax's software solutions, is a positive sign for long-term stability.

What we're watching

Geopolitical Risk
The company's commentary on the Middle East conflict highlights a potential vulnerability; sustained disruption could impact demand despite AAR's stated resilience.
Acquisition Integration
While HAECO Americas integration is ahead of schedule, the success of the pending A-R-T acquisition will be critical for realizing anticipated synergies and driving further growth.
Margin Sustainability
The improved EBITDA margin is partly attributed to a shift towards higher-margin offerings; maintaining this trend will depend on continued execution and pricing power in a competitive market.

AAR Secures $450M Air Force Pallet Contracts, Extending Decades-Long Partnership

Event summary

  • AAR CORP. has been awarded two sole-source contracts totaling up to $450 million by the U.S. Air Force.
  • One contract, valued at $160 million, covers repair services for 463L Legacy Cargo Pallets, with completion expected by March 2031.
  • The second contract, valued at $290 million, involves the manufacture and production of 463 legacy air cargo pallets, slated for completion by March 2032.
  • AAR has served as the primary supplier of 463L Pallets to the U.S. Air Force since 1963.

The big picture

This contract win reinforces AAR's position as a critical supplier to the U.S. Air Force, representing a significant portion of its government solutions revenue. The long-term nature of the contracts provides revenue visibility, but also highlights AAR's dependence on government spending and its ability to maintain a competitive advantage in a niche market. The continued use of legacy pallets suggests a complex modernization timeline within the Air Force’s logistics infrastructure.

What we're watching

Contract Execution
The firm-fixed-price nature of the repair contract means AAR’s margins will be heavily influenced by operational efficiency and cost management over the next seven years.
Competition Dynamics
While AAR has a long history as the primary supplier, the sole-source nature of these contracts raises questions about potential future competitive bidding processes and pricing pressures.
Pallet Obsolescence
The continued reliance on 'legacy' pallets suggests a slower transition to newer cargo systems, and AAR's ability to adapt its offerings to future Air Force requirements will be crucial.

Supply Chain Resilience
Given ongoing geopolitical instability and supply chain disruptions, AAR’s ability to ensure consistent availability of the LASEREF IV system will be a key differentiator and a test of its distribution infrastructure.
Integration Risk
The collaboration's long-term value will depend on the seamless integration of AAR's and Otto's operational processes, particularly in technical support and logistics, to avoid friction and maintain customer satisfaction.

  • He most recently served as President of Elgin, Trackless, and Vactor at Federal Signal Corporation.
  • Sarah Flanagan is returning to her role as Vice President, Financial Operations.
  • AAR reaffirmed its existing financial guidance for Q3 and the full fiscal year.

The big picture

AAR's decision to bring back Dylan Wolin, who previously held key strategic roles, indicates a desire to accelerate growth and potentially refocus the company's direction. His experience in corporate development and capital markets suggests a focus on inorganic growth and shareholder value creation. The move also highlights the importance of continuity and institutional knowledge within AAR's leadership team, particularly given the complexities of the aerospace and defense aftermarket.

What we're watching

AAR Expands Oklahoma City MRO, Solidifies Alaska Airlines Partnership

Event summary

  • AAR CORP. has completed an 80,000+ square foot expansion of its Airframe MRO facility in Oklahoma City.
  • The expansion adds three maintenance bays capable of servicing all 737 variants.
  • The project is expected to create 200 new full-time jobs at AAR.
  • AAR will induct additional Alaska Airlines aircraft into service as part of a long-term agreement.
  • The Oklahoma City facility has a history of maintenance operations dating back over 50 years.

The big picture

AAR's expansion reflects the ongoing trend of airlines outsourcing MRO work to specialized providers. The long-term agreement with Alaska Airlines signals a deepening relationship and provides AAR with a stable revenue stream, but also highlights the concentration risk associated with a single major customer. The digitization initiative underscores the increasing importance of technology in the aviation maintenance sector.

What we're watching

Customer Dependence
Alaska Airlines represents a significant portion of AAR's business, and the long-term nature of this commitment warrants monitoring for potential shifts in Alaska's fleet strategy or outsourcing needs.
Digitization
The collaboration with Alaska Airlines to digitize maintenance processes could significantly impact AAR's operational efficiency and margins, but the timeline and cost of implementation remain key risks.
Capacity Utilization
The success of the expansion hinges on AAR's ability to fill the new maintenance bays, and a slowdown in air travel or increased competition could impact capacity utilization rates.
