Shares of GE Aerospace tumbled as much as -4.0% to $300.56 on October 30, even after the company posted third-quarter results that topped Wall Street estimates and raised its full-year 2026 guidance. The culprit: what lies ahead looks murkier than what just happened. GE Aerospace Crushed Its Quarter — But a $300 Million Engine Problem and a Soft Holiday Finish Have Wall Street Asking What Comes Next

Shares of GE Aerospace slid 4% to $300.56 on October 30, even as the company sat on one of the best quarters in its post-breakup history. The company reported Q3 adjusted EPS of $2.25, beating the $2.01 consensus estimate, while revenue of $13.29 billion topped expectations by over $400 million. The sell-off reveals a market that cares less about what just happened and more about what's coming.

• A Blockbuster Quarter Wasn't Enough to Satisfy Investors. Year-to-date orders, revenue, and total engine deliveries all rose more than 20%.

Management lifted its full-year EPS guidance to $8.00–$8.10 and free cash flow to $9.1–$9.4 billion. Yet the stock dropped because the raised guidance, when you subtract what was already earned in the first three quarters, points to a softer Q4 — implied earnings of roughly $1.87–$1.97 per share, about 6% below the $2.04 Wall Street expected, according to TD Cowen. In other words, the full-year raise wasn't big enough to keep Q4 from looking like a step down.

• A New Engine Program Is Bleeding Money Before It Can Earn Any. GE expects its GE9X engine program — the powerplant designed for Boeing's long-delayed 777X widebody jet — to create a roughly $300 million year-over-year profit headwind in 2027 as shipments to Boeing rise, even though per-engine costs are expected to fall.

In the aerospace industry, new engine programs typically launch with negative profit margins that flip to high profitability as production scales and decades of lucrative aftermarket servicing begin.

Management expects adjusted margins in 2027 to stay flat with 2026, with real expansion resuming only in 2028 as GE9X losses ease and maintenance revenue on its newer LEAP engine matures.

• The Services Cash Machine Is Still Humming — and That's What Really Counts. Management raised its outlook, citing a $170 billion-plus commercial services backlog and low-double-digit services growth projected for 2027.

LEAP engine shop visits — the bread-and-butter repair work that generates high-margin revenue — grew about 40% year-over-year in Q3. The near-term GE9X drag is real, but the long-term profit engine is the recurring service revenue from thousands of jets already flying.

• January's Guidance Update Will Be the Real Test. The 2027 outlook may matter most: management said GE Aerospace will nearly hit its original 2028 profit target two years early, meaning the January report must set a new, higher bar. Until then, investors are stuck weighing a dominant franchise against a Q4 slowdown and a costly engine ramp that won't pay off for at least a year.
