RTX's Commercial Aftermarket Liftoff: Can It Overcome Tariff Gravity?

Read MoreHide Full Article

Key Takeaways

  • RTX's commercial aftermarket sales grew 21% in Q1 2025, driving strong overall performance.
  • Higher steel and aluminum tariffs forced RTX to lower its 2025 EPS forecast to $5.80-$5.95.
  • Global air traffic growth is fueling aftermarket demand, giving RTX a solid long-term buffer.

RTX Corporation’s ((RTX - Free Report) ) commercial aerospace aftermarket segment has proved to be a key performance driver for the company in recent quarters, thanks to steadily growing air traffic necessitating increased usage of aftermarket parts and services. Indeed, the rising number of airline passengers in the post-pandemic era has been fueling demand for aircraft maintenance and repair services, especially as airlines continue to operate older fleets due to new aircraft production delays.

As a result, the robust aftermarket activity in commercial aerospace helped RTX achieve a solid 9% year-over-year organic sales increase in its last reported quarter, partially driven by double-digit growth witnessed in its commercial aftermarket sales. For the first quarter of 2025, the company registered a similar robust growth of 21% in its commercial aftermarket sales.

With global air passenger traffic expected to grow 5.8% year over year in 2025, as predicted by the International Air Transport Association (“IATA”) in its June 2025 outlook, we expect RTX’s commercial aftermarket sales to continue to show stable growth trends in the coming quarters.

However, the recently heightened import tariffs by the U.S. government, particularly on steel and aluminum, can be expected to pose a risk and even curb the extent of the liftoff in its commercial aftermarket business. In particular, these tariffs, expected to result in a plausible upward cost pressure on aftermarket parts manufacturing, prompted RTX to revise its 2025 profit forecast downward. The company now projects its adjusted earnings per share to be in the $5.80-$5.95 range, down from the previous guidance.

Nevertheless, RTX’s outsized growth in the commercial aftermarket should continue to offer it a solid buffer and strong incentive for long-term investors, provided it can successfully navigate industry headwinds and sustain operational momentum.

Other Stocks to Get the Tariff Heat

RTX apart, other aerospace stocks, such as Boeing ((BA - Free Report) ) and Lockheed Martin ((LMT - Free Report) ), which serve the commercial aftermarket industry, remain vulnerable to tariff impacts and may bear the brunt of the resulting cost pressure.

Notably, Boeing Global Services (“BGS”) unit’s parts distribution network provides access to more than 15 million parts worldwide. The company offers a variety of maintenance, repair, and overhaul (“MRO”) services, as well as airplane storage services, at several locations worldwide, including China, Ireland, the UK, and the United States.

On the other hand, Lockheed Martin’s Derco has been providing maintenance, fleet management, upgrades, and a wide range of aircraft spares and components to commercial customers worldwide since 1979. Some of the commercial aircraft platforms that Derco serves include Boeing 747, 777, Airbus A320 and A340.
