AIR vs CW

Key Takeaways

• AIR delivered a notable ~66% one-year total return as of late July 2026, driven by strong momentum in aviation aftermarket parts distribution and software expansion, while CW posted a ~57% one-year return fueled by record defense and commercial nuclear demand.
• AAR Corp is an aviation services pure-play with a market capitalization of approximately $5.1 billion, whereas Curtiss-Wright is a diversified industrial technology company valued near $27.7 billion — a roughly 5x size differential that shapes their respective risk profiles.
• Curtiss-Wright boasts substantially higher operating margins (~18.6% adjusted in FY2025) and generates significant free cash flow (FCF), while AAR operates at lower but rapidly improving margins (~11.8% adjusted EBITDA margin) with a more aggressive growth trajectory.
• Both companies are riding secular tailwinds in aerospace and defense spending, but their exposure differs: AIR leans heavily on commercial aviation aftermarket demand, while CW benefits from naval defense programs and the global nuclear energy renaissance.
• Curtiss-Wright returns capital to shareholders through dividends and aggressive buybacks ($465 million in FY2025), whereas AAR currently prioritizes deleveraging and organic reinvestment over shareholder payouts.
• On valuation, AIR trades at a trailing P/E (price-to-earnings ratio) of roughly 27x, while CW commands a richer multiple near 55x — reflecting the market's premium for CW's higher-margin, diversified earnings stream.

Introduction

In the industrials sector, few comparisons are more instructive than that between AIR (AAR Corp) and CW (Curtiss-Wright Corporation). Both companies serve aerospace and defense end markets and have delivered exceptional shareholder returns over the past twelve months. Yet beneath the surface, they occupy meaningfully different positions along the value chain. AAR is a focused provider of aviation aftermarket services — parts distribution, maintenance, repair and overhaul (MRO), and software solutions — while Curtiss-Wright is a diversified engineered products and systems company spanning naval propulsion, defense electronics, and commercial nuclear power. This stock comparison is relevant for investors seeking to understand how two aerospace-adjacent industrials with different business models, scale, and financial profiles stack up in the current market environment.

AIR Overview and Recent Performance

AIR (AAR Corp), headquartered in Wood Dale, Illinois, has been one of the stronger performers in the aerospace aftermarket space in recent months. The company provides essential services to commercial airlines and government operators globally — from new parts distribution and used serviceable material (USM) sales to airframe MRO, landing gear repair, and its fast-growing Trax aviation software platform. In its fiscal year 2025 (ended May 2025), AAR reported record sales of $2.8 billion, representing 20% year-over-year growth, while adjusted EBITDA (earnings before interest, taxes, depreciation, and amortization) rose 34% to $324 million.

Recent market activity has reflected investor enthusiasm for AAR's strategic transformation. The company substantially completed the integration of its Product Support acquisition, divested its Landing Gear Overhaul business for $48 million, and continued to win high-profile software contracts — including a landmark Trax implementation across Delta TechOps' line maintenance network. Commercial sales remain the dominant revenue driver at roughly 71% of the total, but government business has also grown at a double-digit pace. Net leverage has declined from 3.58x at the time of the Product Support acquisition to 2.72x, and management has guided for further organic sales growth approaching 10% in fiscal 2026. The stock has responded accordingly, with a one-year gain exceeding 66% as of late July 2026.

CW Overview and Recent Performance

CW (Curtiss-Wright Corporation), based in Davidson, North Carolina, is a diversified global provider of highly engineered products and services across three segments: Aerospace & Industrial, Defense Electronics, and Naval & Power. The company's technologies span naval propulsion systems, control rod drive mechanisms for nuclear reactors, aircraft actuation components, surface treatment services, and advanced electronics for ground defense and aerospace applications. In full-year 2025, Curtiss-Wright delivered record results: $3.5 billion in sales (up 12%), adjusted operating income of $651 million (up 19%), and adjusted diluted EPS of $13.23 (up 21%).

Curtiss-Wright's recent momentum has been underpinned by its "Pivot to Growth" strategy, which has translated into an impressive adjusted operating margin of 18.6% — a 110-basis-point expansion year over year. The company generated record FCF of $554 million and a book-to-bill ratio of 1.2x, signaling sustained demand ahead. New orders reached $4.1 billion for the full year, and backlog grew 18% to $4.1 billion. The commercial nuclear and naval defense markets have been particularly robust growth drivers. Curtiss-Wright also executed a record $465 million in share repurchases during FY2025 and maintains a quarterly dividend. The stock has risen approximately 57% over the past twelve months, with a notably lower beta of 0.86, indicating less volatility relative to the broader market.

Head-to-Head Comparison

The most fundamental contrast between AIR and CW lies in their business model architecture. AAR is a services-intensive company — its value proposition hinges on distribution scale, MRO throughput, and software adoption within the global aviation fleet. Curtiss-Wright, by contrast, is a product- and systems-oriented manufacturer with deep proprietary technology moats in naval propulsion, nuclear reactor components, and defense electronics. This distinction translates directly into profitability: CW's adjusted operating margin of 18.6% nearly doubles AIR's adjusted EBITDA margin of roughly 11.8%.

On growth, AAR holds the edge in recent organic sales momentum, driven by market share gains in new parts distribution and the global airline industry's sustained demand for aftermarket support. AIR's revenue base of $2.8 billion is growing from a smaller base and has room for further margin expansion as acquisition synergies materialize. Curtiss-Wright's $3.5 billion revenue base is growing at a solid but more moderate pace, with management guiding for 6–8% organic sales growth in 2026. However, CW's growth is arguably more durable given its $4.1 billion backlog and exposure to multi-year naval defense and nuclear infrastructure programs.

Risk profiles differ meaningfully. AAR carries higher net leverage at 2.72x and remains more sensitive to commercial airline cycles, fuel prices, and air travel demand fluctuations. Curtiss-Wright benefits from a more balanced revenue mix across defense, commercial aerospace, nuclear power, and general industrial end markets, which cushions against single-sector downturns. CW also boasts substantially stronger FCF generation ($554 million versus AAR's more constrained cash flows), giving it greater capital allocation flexibility.

Valuation is another key differentiator. AIR trades at approximately 27x trailing earnings, while CW commands roughly 55x — a premium that reflects CW's superior margins, FCF profile, and diversified revenue streams. However, this premium also means that AAR may present a relatively more accessible entry point for investors willing to accept higher operational leverage and sector concentration risk.

Tickeron AI Verdict

Based on observable trend consistency, margin quality, backlog visibility, and risk-adjusted positioning, Tickeron's AI-powered analytical framework would likely express a cautious preference for CW in the current market environment. Curtiss-Wright's combination of record backlog, expanding operating margins, robust FCF generation, and diversified exposure across defense, nuclear, and commercial aerospace creates a more stable foundation for sustained outperformance. Its lower beta and consistent capital return program further strengthen the risk-adjusted case. That said, AIR remains a compelling growth story — particularly for investors with higher risk tolerance who seek leveraged exposure to the commercial aviation aftermarket recovery and are comfortable with ongoing deleveraging dynamics. Both stocks have demonstrated strong relative performance, but the AI verdict leans toward the steadier, higher-margin operator with deeper backlog visibility.
