AST SpaceMobile vs. GE Aerospace: Which Industrials Stock Is a Better Buy in 2026?

GE Aerospace is presented as the preferred 2026 investment, supported by FY2025 revenue of nearly $46 billion (+18.5%), net income of about $8.7 billion, and $7.3 billion of free cash flow. FY2026 revenue is projected to rise more than 18% to $52.3 billion, aided by defense and commercial engine awards exceeding $2.4 billion, while valuation is materially lower than AST SpaceMobile at 41.7x forward P/E and 7.5x sales versus 186.0x and 357.1x. AST SpaceMobile generated nearly $71 million in FY2025 revenue (+1,500%) but remains deeply loss-making, with a $341.9 million net loss and roughly $1.1 billion free-cash-flow outflow despite its satellite-network growth potential.

Analysis

GE’s earnings power is more levered to fleet utilization and high-margin aftermarket shop visits than to headline aircraft deliveries. The key 6-18 month upside is that constrained engine availability raises the economic value of spare engines, maintenance contracts, and pricing discipline; this can support free-cash-flow conversion even if OEM volume growth moderates. The less appreciated risk is that revenue growth materially exceeding profit growth implies mix, productivity, or working-capital pressure—making 2026 cash-flow guidance and services margins more important than order announcements.

ASTS remains an underwriting exercise on constellation deployment, regulatory clearance, spectrum access, and network capacity—not on the size of its carrier-partner addressable market. Carrier equity stakes and commercial agreements reduce go-to-market risk but do not establish end-user pricing, take rates, or the capital intensity required to provide commercially useful broadband at scale. A further equity raise before self-funded operations would likely matter more to the stock than initial revenue beats, while Starlink direct-to-cell, GSAT/Apple and IRDM represent competitive benchmarks that could compress eventual wholesale pricing.

Consensus framing treats GE as the lower-risk compounder and ASTS as the asymmetric disruptor, but both may be vulnerable to unrealistic assumptions: GE’s multiple requires sustained aftermarket execution, while ASTS’s valuation requires unusually rapid conversion from technical milestones to cash generation. The near-term setup favors GE on measurable quarterly KPIs; ASTS should trade primarily on launch cadence, satellite functionality, carrier commercialization terms, and financing rather than conventional sales multiples.

Key Decisions for Investors

• Initiate/maintain a 6-12 month long GE position on pullbacks around earnings or supply-chain noise. Underwrite to services-margin expansion and free-cash-flow conversion rather than revenue growth; reduce if 2026 free-cash-flow guidance is cut, commercial-services margins contract for two consecutive quarters, or LEAP/aftermarket shop-visit assumptions weaken.
• Express relative value as beta-neutral long GE / short ASTS over a 3-6 month horizon only if ASTS borrow is available at acceptable cost. The thesis is that GE has near-term cash earnings while ASTS faces milestone and financing risk; cap gross exposure because a successful launch, regulatory authorization, or carrier prepayment can generate a sharp ASTS squeeze.
• Do not chase ASTS on generic partnership or subscriber-addressable-market announcements. Establish an alert for independently disclosed paid-service pricing, contracted minimum-revenue commitments, satellite availability metrics, and an updated multiyear capital plan; absent those data, the risk/reward is too dependent on dilution assumptions.
• For defense exposure, prefer GE over BA for the next 6-12 months: GE monetizes propulsion and installed-base support while BA retains greater certification, production-rate, and fixed-price program risk. Reassess if GE’s defense awards fail to translate into segment margin or if BA demonstrates sustained production normalization.
