AST SpaceMobile faces high risks and valuation doubts; Rocket Lab seen as safer hold investment.

AST SpaceMobile remains an early-stage company with unresolved risks in deployment, activation, and economics, making its current high valuation questionable. Despite some progress in manufacturing and launches, the company has not sufficiently de-risked its business model. In contrast, Rocket Lab shows more advanced progress with proven launch operations, customers, and improving margins, though it faces some uncertainty with its Neutron rocket. Overall, Rocket Lab is favored as a Hold due to better risk-adjusted positioning, while AST SpaceMobile is recommended as a Sell given its higher execution risks and lack of validated monetization despite similar valuations.
