Rocket Lab says the window for a 2026 Neutron debut is narrowing

In its filing ahead of the Q2 2026 earnings call, Rocket Lab said the window for an end-of-year Neutron launch is narrowing and that the debut could slip into 2027. The company still targets delivering the rocket to the launch pad in Q4 2026, and said exact launch timing depends on first-stage qualification. For traders, Neutron remains the main source of future revenue growth that has not yet started.
