GE Aerospace has shifted its public narrative away from supply chain shortages, even as those constraints continue to weigh on its ability to serve customers.
Just two years ago, management was openly candid about production struggles, with the CEO acknowledging on an earnings call that “our new engine output was disappointing, down 20% sequentially.”
The engine output problem has since improved, but a different shortage has taken its place, one that management now discusses far less prominently.
The remaining bottleneck is in spare parts and materials, not finished engines, and the numbers tell a story that contrasts sharply with the company’s otherwise strong headline results.
Spare parts delinquency, a direct measure of shipments delayed due to supply constraints, grew 20% sequentially in the second quarter of 2026, signaling the company is struggling to meet commitments already made to customers.
Management acknowledged the problem on a recent earnings call, stating “it is a number we are not proud of, because we are failing to meet customer expectations in that regard.”
Spare parts represent roughly 40% of GE Aerospace’s services revenue, making this bottleneck a meaningful risk to the highest-margin segment of the business.
A persistent shortage in forgings and castings is acting as a hard ceiling on fulfilling spare parts demand, which could translate into revenue and profit misses if left unresolved.
Despite the supply chain overhang, GE Aerospace’s headline financials remain impressive, with second quarter 2026 revenue up 24%, earnings per share up 22%, and free cash flow up 43% year over year.
The company also raised its full-year 2026 guidance, lifting EPS expectations to a range of $7.65 to $7.85 and free cash flow guidance to between $8.9 billion and $9.2 billion.
Behind those figures sits a commercial services backlog of roughly $170 billion, up nearly $30 billion since the end of 2024, underscoring the scale of demand the company is working to fulfill.
First quarter 2026 commercial services revenue grew 39% and total orders surged 87%, confirming that the services-led growth thesis is currently overpowering the known supply constraints.
The investment case for GE Aerospace now rests almost entirely on the massive and fast-growing services business, a shift in emphasis that conveniently moves the supply shortage out of the spotlight.
On valuation, the stock trades at 42.1 times earnings compared to an S&P 500 median of 24.4 times, though trailing revenue growth of 22% against a 7.8% median offers some justification for the premium.
The core question for investors is whether management can resolve the spare parts supply crunch before it becomes a visible drag on the very services engine driving the company’s valuation.
