AAR Corp. or TAT Technologies: Which Share Should You Choose in 2026?

Overview of the Aerospace Services Market in 2026

The international aerospace services sector is set for further growth in 2026, fueled by robust demand for air travel, increased aircraft usage, and ongoing expansion in the Maintenance, Repair, and Overhaul (MRO) segment. Airlines, freight carriers, and defense organizations continue to prioritize fleet reliability and operational effectiveness, generating consistent prospects for service providers like TAT Technologies and AAR Corp..

TAT Technologies is recognized for its advanced thermal management solutions, auxiliary power units, and component MRO offerings. In contrast, AAR Corp. operates with a more diversified approach, encompassing MRO, supply chain management, and logistics services. With maintenance needs remaining high in both commercial and military aviation, these companies are well-positioned to capitalize on favorable industry trends. This analysis explores their competitive advantages, financial outcomes, and potential risks to determine which stock may present greater value in 2026.

Key Growth Drivers for AAR Corp. (AIR)

AAR Corp.'s recent momentum is attributed to impressive quarterly results and ongoing investments in operational capabilities and technology, which have bolstered investor trust. In January 2026, AAR reported a 16% increase in revenue and a 31% rise in adjusted net income for its fiscal second quarter compared to the previous year.

The company is enhancing its market footprint through facility upgrades and technological advancements. Notably, AAR completed an expansion of its Airframe MRO center in Oklahoma City, boosting its ability to meet growing demand from both commercial and government clients, as well as MRO partners and original equipment manufacturers. This added capacity is expected to strengthen service delivery and support sustained revenue growth.

Additionally, AAR's Trax division is experiencing significant progress. Trax renewed a multi-year contract with Air Atlanta Icelandic, which, after adopting the eMRO platform in 2024, will now implement eMobility and cloud-based solutions. These upgrades are anticipated to streamline maintenance, enhance efficiency, and improve regulatory compliance, further solidifying AAR’s technological leadership and recurring revenue base.

Growth Catalysts for TAT Technologies (TATT)

TAT Technologies is expanding its backlog through new agreements. In January 2026, the company secured a three-year contract valued at around $14 million with a U.S.-based airline to provide landing gear MRO services for its Embraer E 170 and E 175 aircraft. The deal includes an optional one-year extension, potentially raising the total to approximately $19 million.

These services will be carried out at TAT’s Greensboro, North Carolina facility, aligning with the anticipated increase in overhaul activities as these aircraft enter the early stages of their maintenance cycles. This contract supports TAT’s operational objectives and highlights ongoing demand for landing gear MRO services.
