Why Is Boeing Stock Falling While Revenue Soars Past Peers?

Boeing (BA) grew revenue faster over the past twelve months than any of its aerospace and defense peers, GE Aerospace included, and its stock still fell. It is also the only one in that group running an operating loss. The growth has come with rising airplane deliveries, and the market is waiting to see whether those airplanes earn a margin.

How Does Boeing Rank Next To GE Aerospace?

GE Aerospace is the sharpest comparison. It grew revenue 21.7% over the trailing twelve months, close to Boeing’s 24.8%, on an operating margin of 18.7%, and its stock returned 13.4%. Boeing’s operating margin over the same twelve months was negative 5.4%. Its stock returned negative 4.4%.

Nearly the same growth, opposite margins, opposite returns. RTX grew revenue less than half as fast as Boeing, and its stock returned 25.7%. The market is paying GE Aerospace and RTX for the profit on each sale, and Boeing is the only company in the group with no operating profit to show.

Where Does Boeing Say The Profit On An Airplane Goes?

Management has pointed to long-standing supply chain architecture as a primary factor dictating how margins are distributed between airframers and component suppliers on current delivery programs. Boeing is managing supplier bottlenecks on 787 engine deliveries, which lagged in the first half of 2026 and constrain the ramp from eight to ten aircraft per month. While suppliers maintain healthier margins, Boeing carries the integration and delivery burden.

Commercial Airplanes still lost money on operations in the June 2026 quarter despite handing over 171 airplanes, its most since 2018, though its margin improved from a year earlier on the higher volume.

The CFO says program cash margins on the 737 and 787 sit only slightly above breakeven, held down largely by a pricing drag that fades as deliveries climb and better-priced backlog comes through. The 737 is ramping to 47 airplanes per month. Volume is arriving before the margin does.

What Would Show Boeing’s Deliveries Turning Into Cash?

Cash is the scoreboard. Management guides 2026 free cash flow to $1 billion to $3 billion, on a record backlog of $715 billion. That backlog is more than seven years of revenue at the trailing pace of $94.0 billion, so demand is not the doubt. Landing inside the 2026 range says the deliveries are turning into cash. Missing it says the pricing drag is still eating the volume.

The risk is that the ramp runs through other people’s factories and Boeing’s own labor talks. Past 52 a month on the 737, the CEO expects the climb to get harder. The 787 needs GE’s engines to recover. The engineers’ union, SPEEA, had its contract set to expire October 6, though Boeing and union leaders reached a tentative four-year agreement in mid-September that now awaits member ratification.

None of that settles today. You are being asked to believe that a company whose Commercial Airplanes unit still loses money will turn the fastest growth in its group into the margins GE Aerospace and RTX already earn. That is possible, and it is a lot to ask. If you cannot settle it, our five-factor stock scorecard ranks every stock on growth, profitability, stability, resilience and valuation.

The Best Stock In The Group Is Still A Single Stock

Ranking a company against its peers sharpens the picture, and whichever name wins is still a single stock. Concentration tends to arrive by accident rather than by decision.
