Boeing vs. GE Aerospace: Which Aerospace Stock Is a Better Buy in 2026?

GE Aerospace is presented as the stronger 2026 aerospace investment, with FY2025 revenue of $45.9 billion (+18.5%), net income of $8.7 billion and $7.3 billion of free cash flow, versus Boeing's $89.5 billion revenue (+34.5%) but only a 2.5% net margin and negative $1.9 billion free cash flow. GE is projected to grow FY2026 revenue by more than 18% to $52.3 billion, supported by F-47, U.S. Marine and commercial-airline engine awards exceeding $2.4 billion. Boeing is forecast to grow revenue 9% to $97.7 billion, but consensus expects net income to drop to about $85 million amid safety, supply-chain, certification and leverage risks, despite record backlog growth.

Analysis

The relevant dispersion is not commercial-aircraft demand but cash-conversion quality. GE’s installed-base model converts utilization, spare-parts inflation, and deferred shop visits into recurring service revenue with materially less working-capital drag than airframe production. Continued Pratt & Whitney GTF durability disruption is an underappreciated competitive tailwind: constrained A320neo capacity raises the value of available CFM-powered lift and can extend GE’s aftermarket pricing window, while pressuring RTX’s remediation costs.

BA’s equity remains a levered operational call option rather than a clean aerospace upcycle exposure. Higher delivery volume can initially consume cash through inventory normalization, customer concessions, rework, supplier support, and Spirit integration; therefore revenue/backlog growth is not sufficient evidence of deleveraging. The key 1-3 month catalysts are production-rate approvals, 737-10/777X certification milestones, and any quantified Spirit cost-to-complete update; absent those, upside is likely capped by a refinancing and execution discount.

GE’s near-term risk is that earnings growth lags sales growth as engine deliveries carry lower initial margins and supply-chain expedites persist. That makes the stock vulnerable over days to a guide raise that lacks free-cash-flow conversion, especially at a premium multiple. Over 6-18 months, however, airline fleet aging and constrained new-aircraft deliveries should shift economics toward maintenance and parts, favoring GE over BA and, selectively, RTX.

Contrarian view: the apparent GE-versus-BA choice overlooks Airbus. If BA certification or production recovery slips, EADSY captures incremental airline fleet allocations, while GE can still monetize propulsion and service content across a broader aircraft ecosystem. Verify all cited consensus figures against company filings before sizing: the article’s profitability and valuation inputs should not be treated as independently validated.

Key Decisions for Investors

• Initiate a 6-12 month beta-neutral pair: long GE / short BA, sized 1:1 on aerospace-factor beta rather than dollar value. Target 15-20% relative return from sustained GE service mix and BA execution discount; exit if BA receives durable production-rate clearance plus a credible positive-FCF/debt-reduction guide, or if GE cuts FCF guidance.
• Add EADSY on BA-specific certification or delivery-delay headlines over the next 1-3 months. The trade expresses airline substitution rather than a broad aerospace bet; invalidate if BA demonstrates sustained monthly delivery improvement and major airline order-share data do not migrate toward Airbus.
• Keep RTX as a watch-list hedge rather than a short: a demonstrable GTF shop-visit-cost peak and improved engine availability could reverse GE’s relative aftermarket advantage. Reassess the GE/RTX spread at each earnings release using aftermarket margin, spare-parts growth, and cash conversion rather than revenue.
• Do not add outright BA exposure solely on backlog or revenue momentum. Require evidence of positive free cash flow after supplier and Spirit-related cash costs, plus certification timing that supports 2027 delivery visibility; otherwise downside remains asymmetric if capital-market access tightens.
