Astronics vs. Heico: Which Aerospace Services Stock Offers More Upside?
Read MoreHide Full Article
Key Takeaways
Astronics posted stronger stock performance than Heico, rising 111.9% versus HEI's 20.5% in the past year.
ATRO trades at a lower forward P/E of 21.55X versus HEI's 61.87X, highlighting a more attractive valuation.
Astronics holds lower leverage and higher ROE than Heico, with 22.89% ROE versus HEI's 16.29%.
Rising air passenger traffic worldwide, driving global fleet size, along with ageing aircraft pushing up demand for aftermarket services, is boosting demand for aerospace service stocks like Astronics Corporation (ATRO - Free Report) and HEICO Corporation (HEI - Free Report) . At the same time, escalating geopolitical tensions are driving higher defense budgets worldwide, increasing demand for advanced avionics, electronics and power systems for combat aircraft supplied by these companies.
Together, expanding global fleet, defense modernization and technological innovations are key growth drivers for aerospace services stocks like ATRO and HEI.
Astronics specializes in designing and producing advanced technologies in electrical power, lighting, connectivity and cabin electronics, catering to both commercial airlines and military clients. HEICO, on the other hand, stands out as one of the largest independent aerospace parts manufacturers globally and a key supplier of jet engines and aircraft components.
With aerospace electrification, digitalization and worldwide fleet expansion capturing investor attention, the key question is: Which of these two aerospace service providers is better positioned to deliver stronger returns and long-term resilience? A closer look at the fundamentals of ATRO and HEI can help investors assess which stock may hold greater upside potential.
Financial Stability & Future Growth Drivers: ATRO vs. HEI
Astronics ended June 2025 with a cash and cash equivalent of $13 million. While its long-term debt totaled $159 million, as of June 2025-end, its current debt was nil. So, it is safe to conclude that the stock boasts a solid liquidity position, which should enable it to duly meet its capital expenditure target of $40-$50 million in 2025. A major part of this investment is expected to be dedicated to new product innovations, effectively expanding core competencies in its existing business. This financial stability should also bolster ATRO’s strategy of enhancing its value through strategic acquisitions.
In contrast, Heico’s cash and cash equivalents, as of July 31, 2025, totaled $0.26 billion, which improved sequentially. The company’s long-term debt, as of July 31, 2025, was $2.44 billion, while its current debt was $0.04 billion. This shows that Heico is in a strong financial position in the short term, giving it the flexibility to keep pursuing its steady acquisition strategy, which has been central to its growth.
When it comes to growth drivers, the steadily rising global air passenger traffic over the past few quarters has been boosting the top line for both ATRO and HEI. Consequently, Astronics reported a 3.3% year-over-year increase in sales in the second quarter of 2025, supported in part by a strong 13% rise in sales to the commercial transport market. Meanwhile, Heico’s Flight Support Group posted a robust 18% sales growth in the fiscal third quarter of 2025, driven by continued growth and momentum in its aerospace aftermarket business.
Sales growth in defense-related aerospace parts and equipment, supported by the rising trend of defense product acquisitions worldwide, has also added to the top-line performance of both ATRO and HEI. For Astronics, military sales rose 11% year over year in the second quarter of 2025, driven by higher demand for lighting and safety products. Similarly, higher demand for defense products played an important role in driving a 7% organic sales increase in Heico’s Electronic Technologies Group during the fiscal third quarter of 2025.
Risks of Investing in ATRO vs. HEI
Both Astronics and Heico face industry-specific risks that a prudent investor should keep in consideration before making any strategic decision.
One such risk is persistent supply-chain disruption. In 2025, although Boeing and Airbus announced their plan to increase aircraft production compared with 2024, growth remains below pre-pandemic levels due to ongoing supply-chain disruptions impacting key component suppliers like ATRO and HEI. As Boeing and Airbus are major aerospace OEM clients, limited parts availability and assembly delays could constrain demand for specialized equipment, potentially slowing commercial aerospace-related revenue growth for ATRO and HEI.
Additionally, heightened U.S. import tariffs on many trading partners, imposed this year, threaten to disrupt global trade, further straining supply chains and potentially affecting commercial operations for both companies. These factors pose near-term challenges despite long-term growth opportunities in the aerospace services industry.
