With RKLB’s shares rising over the past six months, investors may have positive views. Let's examine the factors and assess the stock's investment prospects to make an informed decision.
Tailwinds Driving RKLB’s Growth
Rising U.S. national security demand is driving sustained volume across Rocket Lab’s launch and space systems operations. In 2025, the company completed three HASTE hypersonic missions and indicated additional launches in 2026, aligning with evolving Golden Dome priorities. It also secured a prime contract under the SDA Tranche III Tracking Layer program and gained access to future opportunities through a Missile Defense Agency SHIELD IDIQ award. In March 2026, Rocket Lab signed its largest launch agreement for a block buy of hypersonic test flights, reinforcing its growing role in defense and hypersonic testing programs. The agreement strengthens its role as a key defense partner in hypersonic testing, a rapidly growing priority area, while helping build a competitive niche with potential for recurring missions.
The company’s backlog expanded significantly by the end of fourth-quarter 2025, with management expecting a meaningful portion to convert within the next 12 months, including conservative assumptions for key programs. This offers a solid base for 2026, while diversified launch and components activities provide additional revenue upside. The mix of large, phased programs and shorter-cycle work helps reduce visibility risk and supports a more predictable revenue ramp compared with earlier periods.
Rocket Lab is strengthening its capabilities through strategic acquisitions. In February 2026, the company acquired Optical Support, Inc. (“OSI”), a leader in high-precision optical and optomechanical systems. OSI’s advanced lenses and instruments are critical for national security and commercial satellites, enhancing Rocket Lab’s optical systems used in space protection, space domain awareness, missile warning, tracking and defense applications.
Factors Hindering RKLB’s Growth
With a substantial portion of its 2025 backlog in Space Systems and SDA revenues recognized progressively, margin percentages may decline even as revenues and operating leverage rise. This dynamic adds complexity to Rocket Lab’s near-term earnings outlook and could weigh on valuation multiples if investors focus more on short-term margin consistency than long-term margin expansion and scale advantages.
A significant portion of the backlog is tied to U.S. government programs, increasing exposure to budget cycles, procurement timelines, and policy decisions. Regulatory approvals add further uncertainty. These factors can delay program execution and impact revenue timing, creating sensitivity to external decisions beyond the company's control.
