Rocket Lab Tumbles 11% as Neutron’s First Flight Moves to 2027; SpaceX and AST SpaceMobile Pull Back
Rocket Lab's (RKLB) stock fell 11% after delaying Neutron's first flight to 2027 due to manufacturing issues. SpaceX (SPCX) and AST SpaceMobile (ASTS) also saw declines. Rocket Lab's CEO stated the problem is solved, but testing will extend into Q1 2027. The company's backlog is $2.36 billion, up 137% YoY. Investors are watching for Q3 2026 revenue guidance and test campaign progress.
