Rocket Lab's Neutron Slips to 2027: Wall Street Trims Targets, Not Ratings

Rocket Lab investors learned this week that a few cubic centimetres of trapped air inside a carbon-fibre tank dome can cost a growth stock a quarter of its value. Shares of the launch company closed Friday at 45.25 euros, down 8.2% on the day and 26% over the course of a single trading week.

The trigger was Wednesday's announcement that the maiden flight of Neutron — the medium-lift rocket meant to carry Rocket Lab beyond its small-launch niche — has slipped from its original 2026 target into 2027. Air pockets discovered in the upper dome of the first-stage tank forced a rework of the manufacturing process, and the schedule has not recovered since.

The fix is in, the clock is not

In a filing with the US Securities and Exchange Commission, CEO Peter Beck stressed that the production issues have been resolved. What remains is the unglamorous tail of any engineering correction: inspections, replacement parts and reassembly. Completion of those components and the associated checks is expected before the first quarter of 2027, with stage integration and initial testing to follow during that opening quarter.

The distinction matters for how the setback should be read. This is not a design failure or a launch accident but the cost of scaling a composite manufacturing line from the proven Electron to a much larger vehicle. Building rockets rarely follows a straight line, and the jump to heavier payloads demands technological firsts that cannot be bent to a stock market calendar.

Two days, two rounds of cuts

Sell-side reaction came quickly and in two waves. Goldman Sachs moved first on Thursday, trimming its price target to $67 from $75 while keeping a Neutral rating. Citizens followed on Friday, cutting its target to $90 from $130 but maintaining an Outperform stance. KeyBanc had already acted on Thursday, lowering its target to $100 from $135 while staying Overweight. Other houses issued their own reductions, though most retained their largely positive ratings.

The common thread is a recalibration rather than a retreat. Analysts now model Neutron's first flight for the second quarter of 2027, and the loss of the original fourth-quarter 2026 goal forces valuation discounts even among those who back the programme. Rocket building consumes heavy capital during development, and every delay extends that cash-burning stretch.

Electron keeps the lights on

Away from the headlines around the big rocket, the core business is still ticking over. On Monday the company published its next launch manifest for the veteran Electron vehicle. The mission "We're Not Hawking Around," carrying three satellites for HawkEye 360, is scheduled to lift off no earlier than 21 October. Two further flights for customer iQPS are targeted for 4 and 10 November at the earliest.

That steady cadence in the established segment is what gives management room to work methodically through the Neutron hurdles. The stock now sits 66% below its 52-week high, a gap that captures how thoroughly the euphoria has drained out of the name. What is left is the hard reality of rocket manufacturing, where even a minor flaw in materials testing runs into the millions.

For shareholders, the takeaway is patience. 2027 becomes the decisive year: only when Neutron actually leaves the pad will it be clear whether this week's slide was a temporary dent or a lasting markdown on the valuation.
