Rocket Lab Corporation (NASDAQ: RKLB) finished at $55.25 on Thursday, down 6.64%, and the stock is trading at 0.54% above that level in pre-market trading today. The stock has now fallen for two straight sessions, following a 7.85% decline Wednesday to $59.18. The company has a market cap of $33.06 billion, and its shares are roughly 63% off their 52-week high of $151.00.
Neutron Slips to 2027
The most recent round of selling came after Rocket Lab’s operations update on Wednesday following its close. The company said the first launch of its medium-lift Neutron rocket has been pushed to 2027, from its previous Q4 2026 target. The delay comes after engineers found voids in the carbon-fibre composite forward dome of the first-stage propellant tank.
The team reproduced the defect during testing and changed the manufacturing process as a result, CEO Peter Beck said. The dome, however, has yet to be finished and qualified, and it is hoped the cryogenic testing and hydrostatic testing will continue through Q1 2027. The postponement comes after a January 2026 pressure test of the tank, which pushed the launch date to Q4 2026. Neutron was originally scheduled to fly in 2024.
Heavy Volume and a Wide Intraday Range
Rocket Lab has tumbled as much as 16% to open at $49.69 Thursday and then rose to close at $55.25, down 6.64%. Trading volume was around 47.7 million shares, which was approximately 141% higher than the 19.8 million shares traded in the past three months.
The overall market was trending in the opposite direction, with the S&P 500 up 0.33% to 7,744. Space-sector peers Redwire and Intuitive Machines also rose, suggesting Rocket Lab’s decline was driven mainly by company-specific concerns over Neutron.
Analysts Trim Targets but Stay Positive
Some analysts cut their estimates due to the delay, while keeping a positive rating. KeyBanc’s Michael Leshock lowered his target to $100 from $135 and maintained an Overweight rating due to a decrease in expected number of Neutron launches in 2027 and lower valuation multiples for high growth space companies. In the meantime, Clear Street’s Gregory Pendy trimmed his $129 target to $105, but stayed with a Buy rating. Cantor Fitzgerald maintained its $122 estimate and Overweight rating. These targets represent potential upside of approximately 81% to 121%, based on Thursday’s $55.25 closing price.
The Core Business Is Still Growing
Rocket Lab’s existing business continues to expand despite the Neutron setback. Revenue in the second quarter of 2026 grew 62% compared to the same quarter of 2025, reaching $234.1 million, and contracted backlog hit a new high of $2.36 billion.
The company also inked a multi-year agreement with Synspective in September for 20 more Electron missions. The agreement underscores Rocket Lab’s continued revenue from its existing launch operations as it prepares for the launch of its larger Neutron rocket.
What to Watch Next
Rocket Lab is trying to stabilize above Thursday’s intraday low of $49.69, which is the first support level to watch. The 52-week low level of $37.57 is a longer-term low. On the positive side, resistance is just below Wednesday’s $59.18 close and around $60.

Investors will be watching progress on the forward dome and tank qualification, along with updates on Neutron customer contracts. The upcoming quarterly report, expected on Nov. 9, will give new numbers for capital expenditures, cash burn and revenue from a launch. The changes could assist investors in understanding the impact of the delay on Rocket Lab’s growth strategy and financial prospects. This is a market analysis not an investment advice.
