Rocket Lab's Neutron Rocket Delayed to 2027 After Carbon Composite Defect
Published on 10/16/2026 at 17:31 | Editorial boerse-global.de
Rocket Lab has pushed the maiden flight of its Neutron medium-lift rocket from the fourth quarter of 2026 into 2027, after microscopic air pockets were discovered between the carbon fiber layers of the first stage's forward fuel tank dome. The defect surfaced following a switch to automated fiber placement, according to CEO Peter Beck, and it lands at an awkward moment for shareholders: the stock closed at EUR 49.30 in German trading on the day of the disclosure, a drop of 7.2 percent, and now sits 63 percent below its 52-week high.
The setback strikes at the core of the company's growth thesis. Electron, Rocket Lab's workhorse small-launch vehicle, carries roughly 300 kilograms to low Earth orbit — a payload class that caps its addressable market. Neutron is designed to lift up to 13,000 kilograms, putting it in direct competition with SpaceX's Falcon 9 and opening the door to the large, lucrative contracts the company needs to scale. This is not the first slip: an earlier tank ruptured during a hydrostatic pressure test in January 2026, prompting a redesign of both the structure and the manufacturing process. A first flight had once been targeted for 2024.
Engineering Fixes Advance, but the Clock Keeps Ticking
Beck said a rear dome built under the revised process has passed inspection, and a new forward component is now in production. The forward section must nonetheless be rebuilt from scratch and re-certified. The decisive test comes in the first quarter of 2027, when hydrostatic and cryogenic checks of the fully assembled first stage are due to wrap up. Only that result will determine when in 2027 the debut can actually take place.
The nine Archimedes engines, which are meant to generate roughly 6.45 million newtons of thrust at liftoff, still await qualification, as does the launch campaign at the Wallops Island spaceport in Virginia. Should the pressure tests on the newly laminated dome reveal further delamination or material weaknesses, the launch could slide into the second half of 2027 or beyond.
Profitability Milestones Are Tied to the Debut
The timing of Neutron's commercial monetization is the single variable that matters most for valuation. Management has guided to positive adjusted EBITDA in the quarter following a successful first flight, with positive free cash flow expected only 18 to 24 months after that event. Every month of delay pushes that financial inflection point further out. Free cash flow came in at minus USD 110.1 million in the most recent quarter, and a longer runway to launch means higher upfront costs and a longer period of cash consumption.
Should investors sell immediately? Or is it worth buying Rocket Lab?
Strategic commitments add complexity. The planned acquisition of Iridium is expected to close around mid-2027. If Neutron's operational start drags past 2027, the risk rises that Rocket Lab will need to tap capital markets again to fund its investments — a move that would dilute existing shareholders.
A Record Backlog Softens the Blow
The bullish case rests on the underlying business, which is expanding quickly. Rocket Lab posted record second-quarter 2026 revenue of USD 234 million, up 62 percent year over year, while its order book climbed to USD 2.36 billion — a 137 percent increase over the prior year. More than 90 launches are under contract across all programs, and Electron has strung together 56 consecutive successful missions. Bookings continue to flow in, including an agreement with Synspective covering 20 launches, while the Space Systems segment delivers steady contributions. Neutron already has pre-contracts in hand, among them a USD 397 million development order from the US Space Force.
Analysts are divided on how much damage the delay inflicts. Stifel reiterated its buy rating with a USD 132 price target, stressing that no structural design flaw is at play and that customer demand remains intact. Cantor Fitzgerald's Andres Sheppard kept a "Buy" rating and a USD 122 target, pointing to a persistent global shortage of launch capacity. KeyBanc trimmed its target from USD 135 to USD 100 but stayed at "Overweight." Citizens cut its target from USD 130 to USD 90 while maintaining a "Market Outperform" rating, noting that the most tangible effect of the revised timeline is that launch revenue shifts out of fiscal 2027 and 2028.
In that optimistic scenario, Rocket Lab completes a successful debut sometime in 2027, closes the gap to the market leader, and reaches positive free cash flow from 2028.
Chart Levels Define the Risk
For investors, the situation boils down to clear markers. As long as the shares hold above their 52-week low of EUR 32.60, the valuation reflects a market that is pricing the delay as a manageable transition year and expressing confidence in the company's liquidity position. The stock trades at EUR 47.65 in German dealing, down 23 percent year to date. If confidence erodes on fresh technical setbacks in the manufacturing process, a test of lower levels becomes likely — a loss of faith that would materialize if the rebuild schedule for the tank component wobbles again.
The next concrete milestone arrives on November 9, when Rocket Lab reports third-quarter results. Beyond revenue — management recently guided to USD 250 million to USD 265 million — investors will scrutinize updated cash-burn projections. The real technical reckoning follows in the first quarter of 2027, once hydrostatic and cryogenic testing of the fully assembled first-stage tank is complete. Completion of the dome by the end of 2026, followed by faultless integration of the first stage early next year, would give the market the reliable launch date it has long been waiting for.
