Read MoreHide Full Article
Key Takeaways
AAR and TAT Technologies are positioned to benefit from strong MRO demand in 2026.
AIR posted 16% revenue growth and 31% earnings growth, while expanding MRO capacity and tech.
TATT secured a $14M landing gear MRO deal and projects strong 2026 sales and EPS growth.
The global aerospace services market continues to expand in 2026, supported by strong air travel demand, higher aircraft utilization and sustained growth in the Maintenance, Repair and Overhaul market. Airlines, cargo operators and defense agencies remain focused on fleet readiness and operational efficiency, creating steady opportunities for service providers such as TAT Technologies (TATT - Free Report) and AAR Corp. (AIR - Free Report) .
TAT Technologies brings specialized expertise in thermal management systems, auxiliary power units and component MRO services. AAR benefits from a broader and more diversified model that includes MRO services, supply-chain solutions and logistics support. As maintenance requirements remain elevated across commercial and defense aviation, both companies are positioned to benefit from favorable industry conditions. In this article, we compare their business strengths, financial performance and key risks to assess which stock may offer better value in 2026.
Tailwinds for AIR
AIR’s recent performance has been driven by strong quarterly results and continued investments in operations and technology, which have supported investor confidence. In January 2026, the company reported second-quarter fiscal 2026 results with revenue growth of 16% and a 31% increase in adjusted net earnings compared with the prior-year period.
AIR is further strengthening its market presence through facility expansion and ongoing technology initiatives. The company recently completed the expansion of its Airframe MRO facility in Oklahoma City, increasing capacity to address rising demand from commercial and government customers, as well as MRO providers and OEMs. The additional capacity is expected to enhance service capabilities and support long-term revenue growth.
The company is also witnessing solid momentum in its Trax business. Trax extended a multi-year agreement with Air Atlanta Icelandic. After upgrading to the eMRO platform in 2024, the airline will now implement eMobility and cloud hosting solutions. These enhancements are expected to improve maintenance processes, increase operational efficiency and strengthen regulatory compliance, reinforcing AIR’s technology offerings and recurring revenue stream.
Tailwinds for TATT
TATT continues to strengthen its order book with new contract wins. In January 2026, the company signed a three-year agreement worth approximately $14 million with a U.S. based commercial airline to provide landing gear MRO services for its Embraer E 170 and E 175 fleet. The contract includes a one-year extension option that could raise the total value to about $19 million.
The work will be performed at TATT’s Greensboro, North Carolina, facility and aligns with the expected rise in overhaul activity as the E 170 and E 175 fleet enters the early stage of their scheduled maintenance cycle. The agreement supports TATT’s operating plans and reflects steady demand for landing gear MRO services.
