Rocket Lab Corp A (RKLB) fell 5.38% to $64.17 in morning trading, marking a sharp reversal from a modest opening gap higher. The stock has been volatile in recent weeks amid developments around its $8.1 billion Iridium acquisition and progress on its Neutron rocket program. The recent intraday pullback follows a brief rally after the Federal Communications Commission cleared a key regulatory hurdle for the Iridium deal.
What Happened
The stock opened at $68.60, a 1.2% gap higher from the prior close, but quickly reversed course, falling to a session low of $64.15. The decline came despite recent positive developments, including the FCC’s approval of the first step in the Iridium acquisition and continued testing of the Neutron rocket in Virginia. However, the broader space sector has seen mixed momentum, with SpaceX reported to be limiting new Falcon 9 bookings beyond 2028, which could affect the competitive landscape. Rocket Lab’s shares have also been pressured by ongoing unprofitability, with a net loss margin of -21.5% and an earnings per share of -0.28 over the trailing twelve months.
What The Data Shows
The stock has been trading within a 52-week range of $37.57 to $151.00, with recent volatility pushing it toward the lower end. Over the past eight sessions, it has declined 0.8%, from $66.93 to $66.37. The current session has seen 5.6 million shares traded, which is 0.2 times the 3-month daily average. Unusual options activity has also been noted, with $1.8 million in call premiums versus $269,000 in put premiums. The biggest single options print was $824,000. Meanwhile, insiders have sold a total of $303.4 million in the last 90 days, with no buy transactions reported.
What To Watch
The Iridium deal is expected to close in mid-2027, pending shareholder approval on Sept. 24. Investors will also be watching for further updates on the Neutron rocket program and any additional regulatory or technical developments.
