Company Overview
Rocket Lab USA, Inc. (NASDAQ: RKLB) is a space technology company headquartered in Long Beach, California, with operations in New Zealand and the United States. Market capitalization is approximately $35 billion as of March 2026. The company operates in two segments: Launch Services (the Electron small rocket and in-development Neutron medium-lift rocket) and Space Systems (satellite manufacturing, spacecraft components including solar cells and reaction wheels, and end-to-end mission services for government and commercial customers).

Tank Failure Note (January 2026)
During hydrostatic pressure testing, the Neutron Stage 1 tank ruptured. The tank met anticipated flight loads but failed earlier than expected when pushed beyond design margins. Root cause: a hand-laid manufacturing defect at a third-party contractor. Rocket Lab has commissioned an automated fiber placement (AFP) machine for replacement production, which management states is both faster and cheaper than the original hand-laid process. Other qualified hardware (fairing, thrust structure, interstage, Stage 2) is not affected and integration continues.

Management Commentary
We delivered record quarterly revenue of $180 million, which brought our full year revenue to a record $602 million, representing 38% growth year on year.
The benefit of the AFP process is not only faster production but significantly lower cost than the original hand-laid tank.
Q1 2026 is expected to mark peak Neutron R&D spending.
Not quite as dire as moving all of the follow-on flights 12 months later — additional Neutron tail numbers are already being built and other qualified hardware is not being halted.
About 37% of our current backlog is expected to convert into revenue within 12 months.
Rocket Lab is the small launch leader globally for dedicated small satellite missions.

Key Risk Factors
- 1
Neutron execution risk — the Stage 1 tank ruptured during hydrostatic testing in January 2026 due to a hand-laid manufacturing defect. First launch delayed from H1 to Q4 2026. Further delays would increase cumulative development costs beyond the ~$360M already spent.
- 2
Persistent net losses — net loss widened to $198.2M in FY2025 from $190.2M in FY2024, with an accumulated deficit of $1.01B. Free cash flow was negative $321.8M. The company has funded operations partly through $1.15B in ATM (at-the-market) equity sales, diluting existing shareholders.
- 3
Government contract concentration — SDA Tranche 2 ($515M) and Tranche 3 ($816M) alone represent ~72% of the $1.85B backlog. Changes in U.S. defense budget priorities, program delays, or contract renegotiations could materially affect revenue visibility.
- 4
Customer and segment concentration — Space Systems generated ~68% of FY2025 revenue. A slowdown in satellite constellation buildouts or loss of a major customer could disproportionately affect results.
- 5
Competitive landscape — SpaceX Falcon 9 dominates the medium-to-heavy launch market that Neutron targets. New entrants (Blue Origin New Glenn, ULA Vulcan, Relativity Terran R) are also competing for the same contracts.
Verikal Assessment — Key Takeaways
Rocket Lab generated $601.8M in FY2025 revenue (+38% year-over-year), with Space Systems — the division that builds satellites, spacecraft components like solar cells and reaction wheels, and entire satellite constellations for government and commercial customers — contributing approximately 68% of total revenue. The company’s backlog (the total dollar value of signed contracts not yet fulfilled) reached $1.85B, up 73% from the prior year, driven primarily by two large contracts from the Space Development Agency (SDA), a U.S. Department of Defense organization building a network of military satellites. Of this backlog, about 37% is expected to convert to recognized revenue within the next 12 months.
Electron, the company’s small orbital rocket, completed 21 successful orbital launches in FY2025 with a 100% success rate, making it the second most frequently launched orbital rocket globally. Launch cadence — the rate at which a rocket company conducts missions — increased 31% year-over-year. Neutron, the company’s in-development medium-lift rocket designed to carry up to 15,000 kg to low Earth orbit, experienced a setback when the Stage 1 fuel tank ruptured during pressure testing in January 2026. The root cause was traced to a hand-laid manufacturing defect by a third-party contractor. Rocket Lab has since commissioned an automated fiber placement (AFP) machine to build replacement tanks, which management says will be faster and cheaper. First launch is now targeted for Q4 2026, delayed from the original H1 2026 timeline.
The company remains unprofitable, with a net loss of $198.2M in FY2025 and an accumulated deficit — the cumulative total of all losses since the company’s founding — of $1.01B. Free cash flow (cash generated from operations minus capital expenditures) was negative $321.8M. Rocket Lab funded operations in part by raising $1.15B through ATM (at-the-market) equity offerings, a mechanism where a company gradually sells new shares on the open market, which dilutes existing shareholders. The path to profitability hinges on Neutron reaching commercial service and the continued ramp of high-margin Space Systems component sales.
