Industry Context

The aviation aftermarket represents a large and high-growth opportunity, with the Global MRO Total Addressable Market projected at $138 billion in 2025. Key market drivers include strong air travel growth, a growing and aging global aircraft fleet, new aircraft delivery constraints extending aftermarket demand, increasing airline outsourcing of maintenance, constrained capacity, and rising adoption of used serviceable materials (USM). AAR's strategic repositioning and acquisitions align with these trends, positioning it as a pure-play provider benefiting from long-term industry growth.

Comparison to Industry Standards

• AAR is positioned as the largest independent North American MRO provider.
• The acquisition of HAECO Americas makes AAR the largest heavy maintenance provider in North America, as HAECO Americas was previously the second largest behind AAR.
• AAR's proprietary asset evaluation methods for Used Serviceable Materials (USM) allow customers to realize 30-70% cost savings compared to OEM new parts, indicating a competitive advantage in cost efficiency.
• The company's focus on high-value, complex repairs on current and next-gen platforms, along with a growing portfolio of proprietary DER repairs, positions it strongly against competitors in component services.

Stakeholder Impact

• Shareholders: Positive impact from strong financial performance, margin expansion, and strategic growth initiatives. Potential dilution from the equity offering is offset by improved leverage and future growth prospects.
• Employees: Potential for growth and new opportunities through acquisitions and hangar expansions.
• Customers: Enhanced service offerings, expanded MRO capabilities, and advanced software solutions (Trax) are expected to provide greater value and efficiency.
• Suppliers: New OEM partnerships and the planned supplier portal through Trax could create new collaboration opportunities.
• Creditors: Improved leverage ratios and disciplined debt management enhance creditworthiness.

Next Steps

• Win market share via new business wins in new parts distribution.
• Complete Oklahoma City hangar expansion and progress on Miami hangar expansion.
• Drive Component Services volume through cross-selling.
• Secure new business wins in Integrated Solutions Government.
• Complete acquisition integrations and realize synergies.
