Rocket Lab notched two significant operational wins in a single day last week — a successful hot-fire test of the AVac engine for its Neutron rocket and a $11.4 billion expansion of a Pentagon launch contract program. Yet the company’s stock ended the week down 16.48%, closing at €59.30 on Friday after a modest 0.68% intraday gain. Over the past month, the shares have plunged 36.85%, trading roughly 56% below the 52-week high of €133.80 set on May 27. The stark disconnect between milestones and market performance reveals a company caught between accelerating technical execution and acute investor anxiety over its largest-ever acquisition.

The AVac test, conducted on July 17, 2026, marks a critical step for Neutron, the medium-lift vehicle designed to carry larger payloads for commercial megaconstellations and national security missions. The vacuum-optimized version of the Archimedes engine will power the rocket’s second stage, and clearing this hurdle moves the maiden flight timetable forward. That same day, the U.S. Department of Defense increased the total value of its National Security Space Launch Phase Three Lane One contracts by $11.4 billion cumulatively, with Rocket Lab among the beneficiaries alongside Impulse Space and Relativity Federal. The expansion provides multi-year visibility into high-priority government work — a domain where Rocket Lab recently demonstrated end-to-end capability with the VICTUS-HAZE mission, delivering a complete solution including rocket, satellite, and orbital operations.

But the stock’s slide has been driven by a different narrative. The planned $8 billion acquisition of Iridium Communications has spooked retail investors, who fear dilution and integration risks. The selling pressure was amplified earlier in the month when Piper Sandler initiated coverage on Rocket Lab with a Neutral rating, pointing to concerns about the Iridium deal’s execution and valuation. Insider sales and a broader sector-wide pullback in space stocks added further momentum to the rout. Technical indicators now suggest the shares are oversold: the 14-day relative strength index has fallen to 30.2, a level that often precedes a bounce, and annualized 30-day volatility has climbed to 96%.

Should investors sell immediately? Or is it worth buying Rocket Lab?

Despite the bearish sentiment, the broader analyst community remains largely constructive. Of the 16 analysts covering Rocket Lab, 81% rate the stock as a Buy or Strong Buy, with none recommending a sale. Morgan Stanley reaffirmed its Overweight rating and a target of €105, arguing that Rocket Lab is on a trajectory to become a vertically integrated space platform akin to SpaceX. The average analyst price target stands at $117, implying substantial upside from current levels. Piper Sandler’s neutral initiation stands as the most cautious voice, but even that bank acknowledges the long-term opportunity if the Iridium integration can be managed smoothly.

Operationally, Rocket Lab’s trajectory is headed in the opposite direction from its stock. The CEO called the most recent quarter “phenomenal,” citing record revenue, a record backlog, and a wave of new launch contracts. Launch Services brought in $63.7 million during Q1, while the larger Space Systems segment — which builds satellites and critical components — generated $136.7 million. For the current second quarter, management guided for revenue of roughly $233 million at the midpoint, which would represent 61% year-over-year growth. The company’s order book remains thick with government and commercial commitments.

On the chart, the stock now trades about 12% below its 200-day moving average of €67.33. That trend line, along with the €59 level, is being watched as a potential floor, with traders eyeing a possible “buy the dip” reaction if the oversold reading triggers a reversal. Yet volatility is likely to persist until the next quarterly report provides clarity on the Iridium integration plan and the production timeline for Neutron’s structure at the Wallops, Virginia facility. For now, Rocket Lab is a story of two diverging trajectories: one lifting toward operational milestones and record revenue, the other pressed down by the weight of its biggest bet yet.
