Rocket Lab's Neutron Debut Pushed to 2027: Tiny Voids in a Carbon-Fibre Dome Trigger a Brutal Week
Published on 10/17/2026 at 04:02 | Editorial boerse-global.de
Microscopic air pockets trapped between layers of carbon fibre in the forward dome of a first-stage propellant tank were enough to ground Rocket Lab's most ambitious project for another year. The announcement that the maiden flight of the Neutron heavy-lift rocket must wait until 2027 caught investors off guard, and the selling has been relentless: the stock shed 8.2% on Friday to close at EUR 45.25, capping a seven-day slide of 26%.
The Los Angeles Times identified the delay to the launch vehicle as the principal trigger for the rout, which gathered pace as the week wore on. Earlier in the session the shares had been changing hands at EUR 46.05, down 6.6% on the day, and the paper now sits roughly 66% below its 52-week high of EUR 133.80.
A manufacturing flaw, not a design failure
The root cause lies in voids that compromised the safety margins of the composite component, forcing the part to be rebuilt from scratch. CEO Peter Beck has said the underlying production issue is already resolved, but qualification testing and reassembly of the tank will drag on until the end of the first quarter of 2027. A firm launch date will only be set after that.
The first flight had originally been pencilled in for the fourth quarter of 2026 — and before that, for even earlier years. Rocket Lab attributed the rescheduling to difficulties in the tank manufacturing process, which demand extra development time. The operational setback has visibly dented investor confidence, yet the distinction matters: voids in composite materials are a textbook production headache in high-tech manufacturing, not an architectural flaw that calls the entire Neutron concept into question.
The Street trims its numbers
The delay fed straight into analysts' models. Citizens JMP cut its price target to $90 from $130 on Friday while keeping an Outperform rating, pointing to the knock-on effects on future business — above all, the monetisation of planned launches in the coming two fiscal years, which now slips noticeably to the right. A day earlier, KeyBanc had trimmed its own target to $100 from $135, holding at Overweight. Another institution lowered its target to $67 and stayed neutral.
Should investors sell immediately? Or is it worth buying Rocket Lab?
Despite the sizeable reductions, the houses largely left their underlying recommendations untouched — a signal that faith in the longer-term story remains intact. Stifel went further, reaffirming a $132 target and stressing that customer interest in the future launch vehicle is as strong as ever.
What the market is overlooking
Buried under the disappointment is the operational strength of the existing business. Rocket Lab is no longer a pure bet on the future: second-quarter 2026 revenue climbed 62% year on year to around $234 million. More than 80% of that now comes from Space Systems — satellites and space-based infrastructure — with the established Electron launch programme securing the remainder.
The balance sheet backs the ambition. The company ended June 2026 with a record order backlog of $2.36 billion and cash and equivalents north of $2.1 billion, giving it the financial cushion to see Neutron development through without existential strain.
Delayed revenue, not lost revenue
For shareholders, the postponement means that material financial returns from Neutron will arrive later than hoped. A successful maiden flight is the decisive step in establishing Rocket Lab in the market for larger payloads — the rocket is designed to carry up to 13,000 kilograms to low Earth orbit — and in opening new revenue streams. Goldman Sachs responded by lowering its target to $67 from $75, citing the higher cash burn expected over the coming quarters.
Not everyone is heading for the exits. Cathie Wood's ARK used the weakness to add more than 168,000 shares, a vote of confidence in the long-term perspective. The core business is growing briskly, the coffers are full, and demand for alternatives to the near-monopoly held by SpaceX shows no sign of fading.
Until Rocket Lab stabilises the tank manufacturing process, investors will need patience in abundance. The stock's next move is likely to be dictated by progress on the build programme — and by whether thoroughness, which in aerospace must always trump speed, delivers a clean first flight when the countdown finally begins.
