Rocket Lab's Neutron Debut Slips to 2027 on Tank-Dome Rework, and Wall Street Trims Its Targets Without Losing Faith
Published on 10/18/2026 at 06:40 | Editorial boerse-global.de
A faulty fuel-tank component has cost Rocket Lab a year on its calendar and a quarter of its market value in a single week. The company confirmed on Wednesday that the maiden flight of its Neutron rocket will not happen in 2026 as planned but in 2027, citing manufacturing defects in the dome of the fuel tank. The stock closed Friday at 45.25 euros, down 8.2% on the day, extending a seven-day slide that has wiped out 26% of its value.
At the root of the problem is a production issue rather than a design failure. Rocket Lab reported flaws in the manufacturing process for the fuel tank, and according to media reports a new forward dome must now be built, cured and inspected — work expected to wrap up by the end of the year, ahead of first-stage testing. CEO Peter Beck said in a mandatory filing with the US Securities and Exchange Commission that the manufacturing difficulties have been resolved, though the necessary investigations and rework still take time.
That distinction matters for how the setback should be read. The engines and the overall architecture of the rocket remain unchanged; what failed was a piece of craftsmanship, not the concept. Rocket Lab's smaller Electron vehicle continues to carry payloads reliably, but Neutron is the rocket meant to open the door to lucrative large contracts and constellation launches. Every quarter of delay ties up capital and pushes future revenue further out.
Analysts Cut Their Numbers, Not Their Ratings
Wall Street's response was swift but notably measured. Citizens lowered its price target to $90 from $130 on Friday, explicitly citing the delayed Neutron launch and its knock-on effect on monetizing missions — yet kept its Market Outperform rating. KeyBanc had already moved on Thursday, trimming its target to $100 from $135 while reaffirming Overweight. Both houses are sending the same signal: the technology and business model remain intact, but the road to commercial maturity is longer and rougher than assumed.
Should investors sell immediately? Or is it worth buying Rocket Lab?
Selling began in after-hours trading following the announcement, Reuters reported, and carried through to the end of the trading week. The stock now sits 66% below its 52-week high, a gap that captures how thoroughly the euphoria has drained out of the name. The market is no longer pricing the vision; it is pricing the calendar.
For a growth company with heavy capital needs, that shift raises an uncomfortable question: how long can it stretch its backers' patience? Rocket Lab's management has shown in the past that it can work through technical challenges methodically, and the current hurdle — a composite component that needs to be remade and recertified — falls squarely into that category. In rocket manufacturing, where even a minor deviation in materials testing can cost millions, such delays are hardly exotic.
2027 Becomes the Proving Ground
What investors are left with is a waiting game and a much more realistic starting point for the months ahead. The sharp markdown has already priced in the lost time; the disappointment belongs mostly to short-term traders who had bet on a smooth debut. Once the new tank dome clears its test stands, attention is likely to swing back to Neutron's long-term potential.
Until then, Beck and his team face a test of their own: proving that the Neutron delay was an isolated incident rather than a sign of deeper problems in ramping production. The rocket's first flight in 2027 will be the moment that decides whether this week's selloff was a passing dent or a lasting discount.
