    Executive summary

    Rocket Lab Q3 FY25 — Record Revenue and Strong Backlog Growth

    Rocket Lab delivered record Q3 FY25 revenue and strong gross margins, driven by robust Space Systems performance and accelerating Electron demand, resulting in a record launch contract backlog. While Neutron's first launch is now targeted for Q1 2026 to ensure thorough testing, the company maintains a strong liquidity position of over $1 billion for strategic M&A and organic growth initiatives, aiming for future operating leverage and positive cash flow.

    Highlights

    5

    • Record revenue of $155 million, up 48% year-on-year.

    • Strong GAAP gross margin of 37% and non-GAAP gross margin of 41.9%.

    • Largest Launch contract backlog yet with 49 launches on contract.

    • 16th mission launched this year, equaling last year's record, with a 17th expected soon.

    • Total backlog of $1.1 billion, with 57% expected to convert in the next 12 months.

    Concerns

    5

    • Neutron first launch pushed to Q1 next year, extending R&D spending with a labor cost of $15 million per quarter.

    • Launch Services revenue declined 12.3% quarter-over-quarter due to fewer launches from customer spacecraft delivery delays.

    • GAAP operating expenses of $116.3 million and non-GAAP operating expenses of $98.1 million exceeded guidance ranges.

    • Adjusted EBITDA loss of $26.3 million was below the guidance range of $21 million to $23 million loss.

    • Non-GAAP free cash flow was a use of $69.4 million, compared to a use of $55.3 million in Q2.

    Neutron Development Programunderway
    Spent to date: around $360 million exiting 2025

    Benefit: First launch in Q1 2026, second launch in 2026.

    Investments ramped up in propulsion, test and integration of mechanical composite structures. Capital expenditures remain elevated as we invest in testing, production scaling and infrastructure expansion. Approaching peak R&D spending. Original estimate of $250M-$300M exceeded.

    Return on Investment (ROI) Bargeunderway

    Benefit: 3 main propulsion generating sets, each capable of more than 3 megawatts of electrical power (2.5x total electricity capacity for Launch Complex 3).

    Propulsion generating sets recently passed factory acceptance testing and have been cleared to be sent to the shipyard in Louisiana. Will not be used for the first flight.

    Risks & headwinds

    3
    Neutron Development DelaysOngoing, with first launch now targeted for Q1 next year.

    Labor cost for the program is about $15 million a quarter.

    Mitigation: Prioritizing thorough testing and risk retirement over rushing to launch, ensuring reliability.

    Government Shutdown Impact on New AwardsOngoing

    Timing of new awards for the SDA Tranche-3 constellation has been delayed.

    Mitigation: Existing and fully funded contracts (e.g., $0.5 billion program) continue. Management is confident in competitive position for future awards.

    Customer Spacecraft Delivery DelaysQ3 FY25

    Launch Services revenue declined 12.3% quarter-over-quarter.

    Mitigation: Expect a strong return to sequential revenue growth in the launch business in Q4 due to a busy manifest.

    Why it matters

    Verifies the company's methodical development approach and unlocks future Neutron bookings and NSSL awards.

    So we're aiming to get to a new trend of the pad in Q1 next year, if all goes well with the first launch thereafter.

    Q&A highlights

    7

    What is driving the strong international launch bookings, and how is the supply chain for Electron handling the demand?

    Strong commercial and space agency bookings are driving demand, with Electron being a preferred small launch vehicle globally. Electron's supply chain is robust as over 90% of its components are built in-house, mitigating challenges.

    “Electron's like 90% plus built in-house. So we don't see too many challenges there.”

    Detailed Narrative

    01

    Electron Launch Cadence and Demand

    Rocket Lab achieved its 16th launch this year, equaling last year's record, with a 17th planned in the coming days, demonstrating accelerated Electron demand. The company secured 17 dedicated launches in Q3 alone, primarily from international customers in Japan, Korea, and Europe, contributing to its largest-ever launch contract backlog of 49 missions. The HASTE program continues to redefine hypersonic testing, leveraging Electron's agility and responsiveness for next-generation defense programs.

    02

    Neutron Development Progress and Timeline Adjustment

    Neutron development is progressing with extensive testing of major assemblies, subassemblies, and systems, including the unique 'Hungry Hippo' fairing and Archimedes engines. The first launch is now targeted for Q1 2026, with the second flight planned for later in 2026, reflecting a methodical approach to risk retirement and ensuring reliability over speed. The company emphasizes thorough ground testing to avoid learning during first flight, maintaining its reputation for success.

    03

    Space Systems Performance and Strategic M&A

    The Space Systems segment delivered $114.2 million in revenue, a 16.7% sequential increase, driven by robust satellite manufacturing. The acquisition of GEOs strengthens national security offerings and prime contractor capabilities, particularly for programs like Golden Dome and the Space Development Agency. The Mynaric acquisition, a laser communications company, is nearing completion after its financial restructure, establishing Rocket Lab's first European foothold. The company maintains over $1 billion in liquidity for future strategic M&A.

    04

    Financial Performance and Outlook

    Q3 FY25 revenue reached a record $155 million, up 48% YoY, with GAAP gross margin at 37% and non-GAAP at 41.9%. The company expects Q4 revenue of $170-$180 million and further gross margin improvement to 37-39% GAAP and 43-45% non-GAAP, driven by a higher mix of launch contributions and increased Electron cadence. Operating expenses remain elevated due to Neutron development, but peak R&D spending is anticipated, leading towards future operating leverage and positive cash flow.

    05

    SDA Programs and Government Shutdown Impact

    The transport layer constellation for the Space Development Agency (SDA) cleared critical design review, moving into spacecraft production. While existing contracts, including a $0.5 billion program, are fully funded and continue, the government shutdown has impacted the timing of📎 new awards for the SDA Tranche-3 constellation. Management remains confident in its competitive position as a prime contractor for these awards, citing strong relationships and capabilities.

    06

    Vertical Integration and Competitive Advantage

    Rocket Lab highlights its vertical integration as a key differentiator, enabling schedule certainty, cost efficiency, and quality control across its programs. This approach, combined with a strong reputation for reliability and a broad technology portfolio, positions the company as a prime contractor for complex space missions. The company aims to amass strategic elements to ultimately deploy things at scale, with Neutron providing multi-ton capability and Space Systems offering comprehensive satellite manufacturing.
