Which Aerospace Stock Stands Out: Astronics or Heico?
Read MoreHide Full Article
Key Takeaways
ATRO posted Q3 2025 revenue growth of 3.8% and a 44% rise in net adjusted earnings year over year.
ATRO's Aerospace segment sales climbed nearly 8.5%, driven by airline cabin power demand and military orders.
HEI reported Q4 fiscal 2025 revenue growth of 19.3% and a 34.3% increase in earnings per share.
Rising global air passenger traffic is driving growth in aircraft fleet sizes, while an ageing aircraft base is increasing demand for aftermarket services. These factors are supporting stronger demand for aerospace service stocks such as Astronics Corporation (ATRO - Free Report) and HEICO Corporation (HEI - Free Report) . At the same time, higher global defense spending, driven by ongoing geopolitical tensions, is boosting demand for advanced avionics, electronics and power systems used in military aircraft supplied by these companies.
Overall, fleet expansion, defense modernization and continued technological innovation remain key growth drivers for aerospace services providers like ATRO and HEI.
Astronics focuses on developing advanced electrical power systems, lighting, connectivity solutions and cabin electronics for both commercial and military customers. HEICO, in contrast, is one of the largest independent manufacturers of aerospace parts worldwide and a major supplier of jet engine and aircraft components.
As trends such as aircraft electrification, digitalization and global fleet growth continue to gain momentum, investors are left with an important question: which of these two aerospace companies is better positioned for long-term stability and returns? A closer review of ATRO’s and HEI’s fundamentals can help assess which stock offers stronger upside potential.
Tailwinds for ATRO
ATRO’s recent performance has been supported by solid quarterly results and targeted acquisitions, which have helped maintain investor confidence. In November, the company reported its third-quarter 2025 results, posting revenue growth of 3.8% and a 44% increase in net adjusted earnings compared with the year-ago period.
Astronics continues to benefit from improving conditions in both defense and commercial aerospace markets. During the third quarter of 2025, its Aerospace segment generated sales of $192.7 million, up nearly 8.5% year over year. This growth was driven by higher demand for cabin power products from airlines and increased orders for lighting and safety products from military customers.
In October 2025, Astronics further expanded its aviation portfolio with the acquisition of Buhler Motor Aviation (“BMA”), a Germany-based manufacturer of aircraft seat actuation systems. BMA produces actuators, electronics, control panels, pneumatic systems and lighting solutions.
The acquisition strengthens Astronics’ existing seat actuation offerings and adds technical expertise along with established product designs. BMA will work closely with Astronics’ PGA subsidiary to enhance seat actuation solutions and support future innovation, reinforcing the company’s position in commercial aerospace and supporting steady growth in this niche segment.
Tailwinds for HEI
HEI’s recent performance has been supported by solid quarterly results and targeted acquisitions, which have helped maintain investor confidence. In December, the company reported its fourth-quarter fiscal 2025 results, posting revenue growth of 19.3% and a 34.3% increase in net earnings per share (EPS) compared with the year-ago period.
In December 2025, HEICO announced that its Flight Support Group subsidiary, Wencor Group, entered into an agreement to acquire EthosEnergy Accessories and Components (Ethos A&C). The transaction is subject to regulatory approvals and customary closing conditions, with completion expected in the first quarter of fiscal 2026.
Ethos A&C specializes in the repair of a wide range of aircraft engine accessories and components, including fuel nozzles, wire harnesses, starters, valves, plenum assemblies, air diffusers and engine parts such as blades, vanes and seals. Once completed, the acquisition is expected to strengthen HEICO’s aftermarket repair capabilities and support earnings growth, further enhancing its position in the global aviation services market.
