Rocket Lab Stock Falls After Neutron Launch Is Delayed Into 2027

Rocket Lab (RKLB) shares dropped 7.9% during trading and 7.3% after-hours after the company delayed the Neutron rocket's maiden flight to 2027. The delay was due to manufacturing defects in a carbon-composite tank component, requiring rework and new production. Neutron is key to competing with SpaceX, and delays increase development costs while pushing back revenue.
