With RKLB’s recent gains in the market, some investors may be tempted to buy the stock immediately. However, it is important to look deeper into what is driving this strong performance before making any decision. The key question is whether the company can sustain this momentum or if there are potential risks that could slow its growth. This helps investors make a more informed and thoughtful choice.

Tailwinds for RKLB

RKLB’s recent performance appears to be supported by notable milestones and contract wins, which have helped sustain investor confidence.

In November 2025, Rocket Lab achieved an important milestone by successfully launching a suborbital mission for the Defense Innovation Unit and the Missile Defense Agency using its HASTE vehicle. The mission carried a main payload from the Johns Hopkins University Applied Physics Laboratory along with several secondary payloads. This launch supports the testing of advanced missile-defense technologies and strengthens Rocket Lab’s role in national security missions.

In the same month, Rocket Lab reached another key achievement when two Explorer-class spacecraft built for NASA and the University of California, Berkeley’s Space Sciences Laboratory were successfully launched for the ESCAPADE mission to Mars. These spacecraft will study the planet’s magnetosphere and highlight Rocket Lab’s growing involvement in deep-space research.

RKLB is also preparing for the first launch of the Neutron rocket, which is expected in the second half of 2025. This should significantly expand Rocket Lab’s launch capacity in the United States and will help it move beyond small satellite launches to compete with larger players in the space industry.

Risks to Consider Before Choosing RKLB

Rocket Lab shows strong growth potential in the near term, but investors should also keep in mind some important risks. One key concern is the company’s high operating costs. Rocket Lab continues to spend heavily on the development of advanced technologies, such as the Neutron rocket, satellite platforms and other space systems. These expenses often exceed revenue growth and have resulted in ongoing losses in recent quarters and might also continue to do so in the near term.
