## Customers

AAR sells to commercial aviation customers such as airlines, aircraft operators, lessors, and independent MRO providers that need reliable parts availability and turnaround time for maintenance events. Government customers—particularly the U.S. Department of Defense and other U.S. agencies, plus foreign governments—buy integrated logistics, aircraft support, and expeditionary capabilities under multi-year contracts and task orders. In Parts Supply, customers purchase both USM and new OEM parts, often benefiting from AAR’s authorized distribution relationships and global fulfillment. In Repair & Engineering, customers use AAR’s certificated repair stations for regulated airframe and component work where compliance, quality, and capacity are critical. Trax software is purchased by airlines and MRO organizations to manage maintenance and operational processes, supporting longer-term, embedded customer relationships.

- **Commercial airlines and aircraft operators** (primary) — Buy new parts distribution, USM, flight-hour component programs, and MRO services to reduce downtime and manage maintenance costs.
- **U.S. Government (DoD/DoS and related agencies)** (primary) — Procure customized, performance-based supply chain logistics and aircraft support programs, plus expeditionary services tied to mission readiness.
- **Foreign governments and defense operators** (secondary) — Purchase logistics support, parts, and aircraft sustainment services similar to U.S. government programs, often via multi-year contracts.
- **MRO providers and aerospace service companies** (secondary) — Buy distributed OEM parts, components, and software (Trax) to support their own maintenance operations and customer programs.
- **OEM partners (authorized distribution relationships)** (emerging) — Use AAR as a channel to reach global operators through exclusive or authorized distribution for specific product lines and markets.

## Geography

AAR operates globally, with sales to foreign customers representing 34.2% of consolidated sales in fiscal 2025, reflecting meaningful exposure to international airline and government demand. The company maintains offices and facilities in several foreign countries and runs repair capacity across the United States, Canada, Asia, and Europe through twelve FAA-certificated repair stations. Ten of these repair stations also hold EASA certification and three hold TCCA certification, enabling work for customers operating under different regulatory regimes. International expansion also occurs through acquisitions and investments, including an operating facility in Thailand acquired with the Product Support business. This footprint supports global parts distribution and repair turnaround but increases exposure to cross-border regulatory, currency, and operational risks.

- Global sales base; foreign customers were 34.2% of FY2025 sales
- 12 FAA-certificated repair stations across US, Canada, Asia, Europe
- EASA/TCCA certifications broaden addressable customer base
- Thailand facility added via Product Support acquisition
- International offices/facilities support parts distribution and programs
- Cross-border operations add regulatory, logistics, and FX complexity

## Strategy

AAR is optimizing its portfolio toward core, higher-margin aftermarket offerings, including divesting the LGO business to sharpen focus. It is investing in digital technologies to improve service delivery, with Trax positioned to scale across large airlines and MRO providers and digital tools driving efficiency in Airframe MRO. Capacity expansion is a near-term operational priority, highlighted by construction of two Airframe MRO facility expansions in Miami and Oklahoma City. The company is also pursuing long-term agreements in both commercial and government markets, including new distribution awards and multi-year U.S. Navy contracts, to increase revenue visibility and deepen customer integration. M&A remains part of the playbook, with integration and synergy capture (e.g., Product Support acquisition) used to expand capabilities and footprint.

- **Expand and modernize Airframe MRO capacity** (medium-term) — More capacity and efficiency supports demand and improves turnaround economics.
- **Grow Parts Supply distribution and USM programs** (short-term) — Authorized distribution and platform-specific USM agreements drive volume and customer stickiness.
- **Scale digital offerings and integrated solutions** (medium-term) — Software and performance-based programs can deepen customer integration and support margin mix improvement.
- **Increase penetration in government sustainment programs** (medium-term) — Multi-year contracts can provide backlog visibility and diversify demand versus commercial cycles.

- Portfolio optimization toward core, higher-margin aftermarket services
- Scale new parts Distribution via OEM authorizations and exclusives
- Expand Airframe MRO capacity (Miami and Oklahoma City expansions)
- Invest in digital tools and Trax to embed into airline/MRO workflows
- Win multi-year government programs (e.g., U.S. Navy P-8A support)
- Integrate acquisitions to add capabilities and improve margins

## Risks

AAR’s results are tied to commercial aviation utilization and maintenance cycles; downturns in flight activity can reduce demand for parts, MRO events, and asset values. The company operates in highly competitive markets against OEMs, airline in-house MRO operations, and other independent suppliers, which can pressure pricing and access to skilled labor. International operations are material (34.2% of FY2025 sales to foreign customers) and create exposure to regulatory compliance, geopolitical disruption, and execution risk in overseas facilities and joint ventures. Government contracting adds risks from bid protests, shifting procurement preferences (including set-asides), and potential insourcing by agencies. Cybersecurity is a persistent threat given reliance on IT systems and defense-contractor requirements, and a high concentration in specific engine/part platforms can create asset-specific demand and valuation risk.

- **Competitive pressure across parts, MRO, and expeditionary markets** [high] — OEMs, airlines with in-house MRO, and larger competitors may underprice or bundle offerings, pressuring margins and share.
- **International operating risk** [high] — A meaningful portion of sales is to foreign customers and the company operates facilities abroad, increasing exposure to country-specific disruptions and compliance requirements.
- **Government contracting execution and award risk** [medium] — Bid protests, contract modifications, set-asides, and agency decisions to insource work can delay or reduce program earnings.
- **Cybersecurity threats and IT disruption** [medium] — Ransomware, denial-of-service, and state-affiliated threats could disrupt operations and increase compliance costs, particularly given defense-customer requirements.
- **Asset/platform concentration in engines and related parts** [medium] — If demand declines or a platform is redesigned/replaced or faces technical issues, asset values and sale/lease rates can fall, impairing returns on inventory/assets.

- Commercial aviation downturns reduce parts demand and MRO volumes
- Intense competition from OEMs, airlines, and independent MROs
- Skilled labor constraints can limit repair capacity and margins
- International operations risk (regulatory, geopolitical, FX, logistics)
- Government contract risk: bid protests, set-asides, and insourcing
- Cyber incidents could disrupt operations and trigger compliance costs
- Asset concentration risk in specific engine/parts platforms (e.g., CFM56)

## Accounting

AAR’s reported results rely on management estimates in several areas that can move earnings and asset values, particularly for inventories and rotable assets where net realizable value depends on demand, aging, and expected scrap recovery. Business combinations are significant: purchase price allocation to identifiable intangibles and goodwill requires fair value judgments, while transaction costs are expensed as incurred, affecting period comparability around deal activity. Goodwill is not amortized and is tested at least annually (May 31) using qualitative or quantitative assessments; changes in market conditions or segment outlook can trigger impairment, as illustrated by impairment recognized in connection with goodwill allocation decisions tied to divestiture actions. Revenue recognition is a critical policy given the mix of parts sales (often point-in-time) and service/program work that may involve different timing patterns and estimates. The allowance for credit losses and other provisions also require judgment and can change with customer mix and macro conditions.

- **Inventory and rotable asset valuation (LCNRV) and write-downs** — Affects cost of sales, gross margin, and working capital
- **Business combinations (purchase price allocation, intangibles, goodwill)** — Affects operating expenses, amortization, and balance sheet composition
- **Goodwill impairment testing** — Non-cash impairment charges can materially affect operating income
- **Revenue recognition across parts sales and service/program work** — Affects revenue timing, contract assets/liabilities, and margins

- Inventory/rotable valuation at lower of cost or net realizable value
- Write-down assumptions: demand, aging, usage trends, scrap recovery
- Purchase price allocation and fair value estimates in acquisitions
- Goodwill annual impairment testing (qualitative approach used recently)
- Potential impairment tied to portfolio changes/divestitures
- Revenue recognition judgments across parts, MRO, and program contracts
- Allowance for credit losses sensitive to customer credit conditions
- Letters of credit and performance bonds affect commitments disclosure
