Rocket Lab announced its first customer for its coming Neutron vehicle. The space infrastructure company reported third-quarter revenue increased to $104.8 million, up 55% from $67.6 million for the same period a year ago.

Reports indicate that Stifel analyst Erik Rasmussen raised his estimated valuation of the New Zealand rocket-maker by more than 50%, from $9 to $15 a share, and has "high-level conviction" that Rocket Lab will succeed in bringing its new Neutron rocket to market.

Shares of Rocket Lab USA Inc. are up 23.7% in premarket trades after the space-launch company highlighted strong demand for its Electron rocket during its third-quarter results Tuesday.
