Wall Street’s Single Big Bet Beyond Apple and NVIDIA: AAR Corp
Wall Street and institutional investors have recently poured a whopping $8 billion into an aviation services company, surpassing NVIDIA and Microsoft. The protagonist is AAR Corp (NYSE: AIR). While AAR may appear to be a simple aircraft maintenance company on the surface, it’s actually evolving into a platform company driving digital innovation across the entire aviation industry.
AAR’s fiscal 2025 performance exceeded investor expectations. Annual revenue reached $2.8 billion, a 20% increase year-over-year, with fourth-quarter revenue of $755 million showing 12% growth. Even more impressive is the improvement in profitability. Adjusted EBITDA margin rose to 11.8%, up 140 basis points from the previous year. This indicates that the company’s fundamentals are achieving structural profitability improvements, not just simple revenue growth.
Fourth-quarter earnings per share of $1.16 recorded an earnings surprise, beating analyst expectations of $1.00 by 16%. This suggests the market had underestimated AAR’s growth potential. On an annual basis, adjusted earnings per share increased 17% to $3.91 from $3.33 the previous year.
AAR’s strength lies in the balanced growth of its four core business segments. The parts supply division recorded $306 million, a 17% increase, with adjusted EBITDA margin expanding from 14.8% to 17.1%. This shows the company is evolving beyond simple parts sales to high-value-added services.
The repair and engineering segment also maintained solid growth, with revenue growing 3% to $223 million, while the integrated solutions segment achieved $181.5 million, a 10% increase.
The strength in government business is particularly notable. Government customer revenue increased 21%, meaning the company secured stable revenue sources even during times of economic uncertainty. Government contracts typically provide predictable cash flows over extended periods.

AAR’s Strength: Revenue Source Diversification
The company consists of four core business divisions:
Parts Supply (40%): Handles used serviceable material (USM) sales and new OEM parts distribution. According to CEO John Holmes, “We tear down dozens of aircraft and engines annually, recertify those parts, and sell them on the open market. These parts have the same part number, form, fit, and function as new parts, but because they’re used, they sell for 30-60% less than purchasing new parts from OEMs.”
Repair & Engineering (32%): Provides aircraft component maintenance, repair, and overhaul services.
Integrated Solutions (25%): Includes supply chain management and Trax cloud-based MRO (Maintenance, Repair, Overhaul) software.
Expeditionary Services (3%): Handles equipment and personnel movement support for military and humanitarian missions.
This business model diversification, encompassing hardware, maintenance, platform software, and services, serves as a buffer against aviation industry cyclical volatility. AAR’s Digital Product Management Vice President Matt Camerit expressed confidence, saying, “During the first 6-12 months of the pandemic, we faced difficulties in the commercial sector, but increased maintenance activities in government and military sectors offset this. Thanks to our diverse business models and independent status, we weathered it well and actually became stronger.”

“The Era of Paper-Based Maintenance is Over”… AAR’s Aviation Digital Revolution
The core reason AAR attracts investor attention lies in its digital platform called Trax. This cloud-based aircraft maintenance (MRO) software platform has created remarkable market value, with business revenue doubling from $25 million two years ago to approximately $50 million in fiscal 2025. Management currently aims to double this again through new contracts including one with Delta Air Lines.
Traditional aircraft maintenance has long relied on analog manual management methods. For extended periods, parts inventory, maintenance schedules, and safety inspections were all paper-based. Trax integrates all these processes into a real-time digital platform, allowing customers to manage maintenance operations remotely not only from desktops but also from smartphones and tablets.
This represents not just technical improvement but a fundamental business model change, enabling transition from one-time service provision to continuous subscription-based revenue models.
AAR is optimizing its portfolio by divesting low-profitability non-core businesses. It completed the sale of its non-core Landing Gear Overhaul business to GA Telesis for $51 million. This is part of a strategic plan to optimize the portfolio by investing in core functions that will accelerate targeted growth and margin expansion initiatives.
The strategy of divesting labor-intensive, low-margin businesses and focusing on high-margin businesses like digital solutions is actually producing results. CFO Sean Gillen explained, “Fourth-quarter total adjusted revenue set a new quarterly record at $736 million with 12% growth, due to strong growth across all business segments.”

AAR’s financial structure is also continuously improving. The net debt ratio decreased from 3.06x to 2.72x, with the target range of 2.0-2.5x not far away. This suggests the company is finding an appropriate balance between growth investments and maintaining financial health, which is a positive signal for investors.
Simultaneously, investments for future growth continue. Oklahoma City and Miami MRO expansions scheduled to become operational in 2026 will add 15% network capacity. This represents proactive investment to meet increasing aircraft maintenance demand.
The company also presented a positive outlook for fiscal 2026, expecting first-quarter revenue growth of 6-11% and adjusted operating margin of 9.6-10%. CEO John Holmes stated, “Organic revenue growth is approaching 9%, and we expect continued improvement in adjusted operating margin at the 9.6% level for fiscal 2025.”
Market experts are also giving positive evaluations of AAR. Major investment banks have set target prices at $75-85, indicating continued investor interest. Most notable is the movement of institutional investors. In August 2025, investors poured $8 billion into AAR, surpassing NVIDIA, Microsoft, and Palantir. This represents the largest capital inflow during that period.
Westwood Holdings Group expanded its AAR stock holdings by 10.3% in the first quarter, securing stakes worth a total of $89 million. JP Morgan increased its holdings by a remarkable 215.9%. Such large-scale capital inflows from institutional investors indicate recognition of AAR’s long-term growth potential.

Insight Bridge AI’s Perspective: The Game Changed by Trax… Aviation Services Company at the Center of AX (AI Transformation)
The background to AAR’s attention lies in structural changes in the global aviation industry. With the number of aircraft worldwide continuously increasing, maintenance demand for older aircraft is rapidly growing. In situations where new aircraft purchases cost hundreds of billions of won, extending the lifespan of existing aircraft is more economically rational.
Importantly, AAR Corp’s rise suggests the market is passing through an important inflection point, beyond being simply an individual company’s success story. The reason institutional investors are focusing on this aviation services company over tech giants like NVIDIA and Microsoft is clear.
First, in situations where inflation and supply chain instability persist, companies are focusing on efficient utilization of existing assets rather than purchasing new assets. AAR’s used parts regeneration business and predictive maintenance services are core beneficiary areas of this trend.
Second, the digital transformation paradigm is changing. Companies that previously focused on IT infrastructure construction are now paying attention to actual work process digitization. AAR’s Trax platform is exactly the epitome and good example of such “practical digitization.”
Third, the importance of “intermediate service industries” is being highlighted in the global supply chain reorganization process. Companies providing specialized services between manufacturers and end users are emerging as the core of new value creation.
AAR’s success shows that the “platform economy” is no longer exclusive to IT companies. It’s being proven that traditional industries can also expand customer touchpoints and increase profitability through digital platforms. This suggests that understanding the essence of business models has become more important than sector classification in future investment strategies.
