Rocket Lab Stock Down 64%: Neutron Slips to 2027 [2026]
Rocket Lab's stock fell 64% from its May high to $54.73 on Oct. 30, after delaying its Neutron rocket's first flight to 2027. The company reported Q2 2026 revenue of $234.1M, up 62% YoY, with a $2.36B backlog. Neutron's delay raises questions about the company's valuation, which is built on both its existing space systems business and the unlaunched rocket.
