Rocket Lab's Neutron Debut Pushed to 2027: A Composite Flaw, a Two-Day Slide, and a $2.1 Billion Cushion
Published on 10/17/2026 at 06:20 | Editorial boerse-global.de
Tiny voids trapped between layers of carbon fibre in the forward dome of a first-stage propellant tank have upended Rocket Lab's near-term roadmap — and investors have responded with a two-session stampede for the exits.
The stock fell 8.2% on Friday to close at EUR 45.25, extending a seven-day decline to 26%. A day earlier it had already shed 6.6% to EUR 46.05. Measured against its 52-week high of EUR 133.80, the shares now sit roughly 66% lower.
At the heart of the selloff is a manufacturing defect: microscopic air pockets in the composite dome of the Neutron rocket's first-stage tank eroded safety margins, forcing the component to be rebuilt from scratch. CEO Peter Beck said the root cause in the production process has already been fixed, but qualification testing and tank assembly will stretch to the end of the first quarter of 2027. A firm launch date will only be set after that.
The maiden flight had originally been targeted for the fourth quarter of 2026 and had been slated for even earlier years before that. The slip pushes back the commercial debut of a vehicle designed to haul up to 13,000 kilograms into low Earth orbit — and with it, the entry into the lucrative medium-payload market.
Two Analysts, Two Verdicts
Wall Street's response came swiftly and in divergent tones. Goldman Sachs' Noah Poponak cut his price target to $67 from $75 on Friday, keeping a Neutral rating and pointing squarely at higher expected costs and a steeper cash burn as the timeline stretches. Citizens trimmed its target to $90 from $130 the same day but stood by its Market Outperform rating, citing the delayed monetisation of launch contracts in fiscal 2027 and 2028.
Should investors sell immediately? Or is it worth buying Rocket Lab?
Stifel, for its part, reiterated a $132 target despite the setback, stressing that customer appetite for the future launch vehicle remains as strong as ever.
The split captures the central question now facing shareholders: can Rocket Lab bridge an extended development stretch without diluting them through a capital raise? Additional engineering and manufacturing costs will accrue over a longer period while the anticipated launch revenue slips away — a double squeeze on the balance sheet.
The Business Beneath the Rocket
What the gloom has obscured, bulls argue, is the strength of the existing operation. Rocket Lab is no longer a pure bet on the future. Second-quarter 2026 revenue jumped 62% year on year to roughly $234 million, with more than 80% of that total now flowing from Space Systems — satellite construction and space-based infrastructure — while the established Electron launch programme provides the remaining base.
The company also ended June 2026 with a record order backlog of $2.36 billion and more than $2.1 billion in cash and equivalents, a buffer that should carry Neutron development through to completion without existential strain.
Institutional money is already moving. Cathie Wood's ARK bought more than 168,000 shares on the dip, a signal of confidence in the long-term story.
What to Watch From Here
Whether the EUR 45 area — the 52-week low — holds as support will shape the near-term trend. A decisive break below it under continued selling pressure could deepen the correction as institutions trim exposure further.
Rocket Lab at a turning point? This analysis reveals what investors need to know now.
The next real tests for investors are detailed progress reports on Neutron's construction and the coming quarterly figures, when management must specify its expected cash consumption and liquidity runway. Only once it demonstrates that the extended development can be absorbed without alarming burn rates are fundamentals likely to give the share price a durable floor.
For the optimists, the case rests on the nature of the setback itself: voids in composite materials are a familiar manufacturing headache in high technology, not an architectural flaw that undermines the entire Neutron concept. Should the fixes lock in the reliability and reusability of the design, the rocket could emerge in 2027 as a competitive alternative in a market where institutional and commercial customers are eager to diversify away from existing monopolies. Demand for dependable orbital transport remains as high as ever.
The bear case is equally clear. Complex space projects rarely stop at a single schedule adjustment. Further technical hurdles could stretch the timeline deep into 2027, and if spending on personnel, test infrastructure and materials keeps climbing while high-margin large launches stay grounded, pressure on capital reserves would mount sharply. In the worst case, Rocket Lab would have to raise fresh equity — at current levels, a painful dilution for existing holders — while rivals that bring their vehicles to market sooner could pry away contracts.
Either way, the hoped-for earnings inflection from Neutron has shifted back by at least three quarters. The debate now is whether the market has priced that delay in full — or whether the tank dome is merely the first of the surprises.
