Rocket Lab Delays Neutron Rocket Launch to 2027 Following Manufacturing Defect

BearishHigh impact
RKLB$59.18 −7.85%IRDM$45.78 −2.03%

Rocket Lab Corporation (RKLB) shares fell nearly 8 percent after the company postponed the maiden flight of its Neutron rocket into 2027. Chief Executive Peter Beck stated that the delay was caused by air pockets discovered in a carbon-composite dome within Neutron's propellant tank. Engineers identified the issue during testing, modified the production process, and successfully fabricated a replacement rear dome.

The schedule push comes as Rocket Lab works to complete a planned acquisition of satellite communications operator Iridium Communications Inc. (IRDM) for $54 per share in cash and stock. The transaction would combine Rocket Lab's launch capabilities with Iridium's profitable network, which brought in $871.7 million in revenue and $114.4 million in net income last year. Rocket Lab had revenue of $601.8 million and a net loss of $198.2 million over the same period.

Rocket Lab aims to finish manufacturing and inspecting the remaining tank components before the end of the year. The assembled first-stage tank will undergo pressure and cryogenic testing during the first quarter of 2027 before a specific launch date is set. Meanwhile, regulatory reviews for the Iridium transaction remain ongoing, with public responses and replies scheduled through early November.
