New York, Feb 4, 2026, 20:48 EST — Market closed.
- Shares of GE Aerospace closed roughly 0.5% lower and continued to drift down in after-hours trading.
- Investors are watching closely as GE reviews a possible durability problem with the GE9X engine powering Boeing’s delayed 777X.
- Announcements at the Singapore Airshow have focused attention on expanding engine repair capacity and boosting service growth.
Shares of GE Aerospace dropped Wednesday, then dipped again after hours amid concerns over a possible durability problem with the GE9X engine used in Boeing’s 777X. The stock closed down 0.5% at $308.33 and fell another 1.1% to $305.00 in after-hours trading.
GE said Monday it is investigating a possible problem linked to a seal in the GE9X engine, but company officials warned it’s too soon to assess the impact. Boeing CEO Kelly Ortberg mentioned the issue during the firm’s Q4 call, confirming Boeing still plans to begin deliveries in 2027. Boeing declined to comment further. The 777X program is already years behind schedule, with Boeing booking over $15 billion in charges, Reuters reported.
The key point now: engines aren’t just a one-off sale. Most profits trickle in through maintenance and spare parts over time. Investors keep a close eye on shop-visit patterns and surprise repairs, nearly as much as on fresh orders. Competitors such as RTX’s Pratt & Whitney and Rolls-Royce are fighting over that same long-term services market.
GE Aerospace expanded its footprint at Singapore’s Seletar Aerospace Park on Wednesday, launching a new module repair facility focused on CFM LEAP high-pressure turbine modules. Tim McQueen, executive director of GE Aerospace’s global component repair network, called it a clear sign of their push to build local MRO capabilities.
At the Singapore Airshow, GE Aerospace and Thai Aviation Industries inked a memorandum aimed at exploring maintenance support for GE engines powering Thailand’s government and military fleets. Rita Flaherty from GE called the deal a chance to “provide timely, advanced maintenance and repair” while boosting GE’s presence in the region. GE Aerospace
Just a day before, GE announced a $300 million investment over five years to upgrade its engine repair facilities in Singapore, focusing on automation, digitization, and AI-driven inspection. Mohamed Ali, president and CEO of GE Aerospace’s commercial engines and services division, called it a move that “will usher in breakthrough capabilities.” GE Aerospace
GE teamed up with Singapore’s aviation regulator and development agencies this week to roll out SPAARC, a research alliance focused on next-gen aviation tech, including AI for safety and airspace management. “This partnership will add new capabilities to Singapore in areas such as AI, air traffic management and aerodynamics,” said Jermaine Loy, managing director of Singapore EDB.

The GE9X seal review is still an open question. Should the findings call for hardware tweaks or more intensive maintenance, Boeing’s already squeezed 777X testing and certification timeline could face setbacks, driving up expenses for both suppliers and operators.
Wednesday’s session was a mixed bag: the Dow climbed, yet the S&P 500 edged down as major tech stocks dropped amid renewed skepticism over high AI-driven valuations, Reuters noted.
In a separate filing, Senior Vice President Amy Gowder disclosed selling 4,000 GE shares at $305.73 each on Feb. 2. After the sale, she still held 16,535 shares.
U.S. markets remain closed until Thursday, leaving investors eager for updates from GE or Boeing on the GE9X review. The Singapore Airshow, ongoing until Feb. 8, is prime time for companies to drop remarks on repair capacity and fleet readiness—comments that can shake aerospace stocks.
