Rocket Lab Stock Falls 13% as Neutron Slips to 2027
Rocket Lab (RKLB) shares dropped 13% after delaying Neutron rocket's first flight to 2027 due to manufacturing defects. Analysts cut price targets: KeyBanc to $100, Clear Street to $105. Neutron's delay impacts revenue projections and investor sentiment, though Electron launches continue.
How this was made

The 30-second read
Why it matters
The forward-dome manufacturing defects push cryogenic and hydrostatic qualification into early 2027, delaying the first operational launch and prompting multiple analysts to cut price targets.
Market read
This is a company-specific execution setback with immediate market repricing and fresh analyst target reductions, making it a near-term catalyst for RKLB positioning.
What to watch
Investors may be over-weighting the headline date change versus the specific qualification milestones (forward-dome completion, cryogenic and hydrostatic testing) that could de-risk the program sooner than implied.
Background
Neutron is Rocket Lab’s planned larger launch vehicle intended to expand beyond small-satellite Electron missions into a broader commercial and government launch market.
Ticker impact
Rocket Lab pushed Neutron’s inaugural flight to 2027 after finding manufacturing defects in the forward dome, driving a double-digit selloff and analyst target cuts.
Likely continued downside pressure as investors reprice the probability-weighted timeline until forward-dome completion and qualification milestones are verified.
The article cites a concrete schedule change to 2027 tied to specific manufacturing defects, plus same-day analyst price-target reductions and a large intraday decline.
Market effects
Highlights execution risk in next-gen launch vehicle development, likely keeping investors selective on launchers with credible qualification progress.
US-listed space names saw broader weakness, but RKLB’s move was more pronounced due to its own program delay.
Could modestly affect sentiment toward commercial and government launch procurement timelines that depend on Neutron’s future capacity.
Counterpoint
Rocket Lab’s existing Electron business and backlog may cushion the impact, and the company claims the manufacturing process was corrected, reducing the chance of further major slippage.
