With RKLB shares falling over the past three months, investors may be reassessing the stock’s outlook. Let's examine the factors and assess the stock's investment prospects to make an informed decision.
Potential Risks to Rocket Lab’s Growth
Rocket Lab remains vulnerable to changes in government spending and customer concentration, as a meaningful portion of its business is tied to U.S. government and defense programs, while a limited number of customers account for a substantial share of revenues. Shifts in government priorities, budget allocations, procurement schedules or contract funding could affect demand for the company's launch and space systems offerings. The loss, delay or cancellation of a major customer program could reduce revenues, backlog and future business visibility.
Rocket Lab operates in a competitive and capital-intensive space industry requiring continued investment in launch vehicles, spacecraft, manufacturing capacity and infrastructure. Competition from established aerospace contractors and emerging launch providers could intensify pressure on pricing and market share, while ongoing investments in technologies such as Neutron could increase costs and weigh on profitability.
Rocket Lab also faces supply-chain risks, as certain raw materials, components, subsystems and services are sourced from sole-source suppliers. Disruptions, shortages, quality issues or longer lead times could increase costs, delay customer deliveries and affect operating performance as the company scales its launch and space systems businesses.
Key Growth Drivers of Rocket Lab
Rocket Lab is strengthening its position in space-based defense through a major satellite and launch award. In August 2026, the company received a $397 million U.S. Space Force contract to develop, build and launch multiple Flatellites for the Space-Based Airborne Moving Target Indicator program. The award highlights Rocket Lab's vertically integrated capabilities and expands its role in high-value national security space programs.
The company also delivered strong second-quarter results, with record revenues of $234.1 million, up 62% year over year, while the backlog reached a record $2.36 billion. Rocket Lab also guided for record revenues in the third quarter, highlighting continued momentum across its launch and space systems businesses.
