Business Commentary:

Record Revenue and Backlog Growth:

• Rocket Lab reported record annual revenue of $602 million in 2025, representing a 38% year-on-year growth compared to 2024. Q4 revenue reached $180 million, up 36% from Q4 last year. The total backlog at the end of Q4 stood at a record $1.85 billion, up 73% from the same time in 2024.
• The growth was driven by a record number of Electron and Haste launches, strong demand for space systems contracts, and strategic acquisitions.

Space Systems and Defense Contracts:

• Rocket Lab secured its largest contract ever, an $816 million deal with the Space Development Agency (SDA) for building a constellation of 18 spacecraft. Combined with previous contracts, Rocket Lab now holds over $1.3 billion in contracts with SDA.
• The growth in this segment was fueled by strong defense and national security interests, with Rocket Lab positioning itself as a disruptive prime contractor in the space industry.

Neutron Program and Infrastructure Expansion:

• Rocket Lab made significant progress on its Neutron program, with key milestones achieved in the qualification of critical flight hardware. The company expanded its manufacturing capacity with the acquisition of Precision Components Limited.
• The investments in Neutron and infrastructure were aimed at supporting the aggressive scaling and production needs of the company's growing launch and space systems programs.

Gross Margin Improvement:

• GAAP gross margin for Q4 reached 38%, and non-GAAP gross margin was 44.3%. For the full year, GAAP gross margin was 34.4%, an increase of 780 basis points year-over-year, while non-GAAP gross margin was 39.7%, an increase of 770 basis points.
• The improvement was driven by increased Electron fixed cost absorption due to higher launch cadence and contributions from higher-margin space systems components businesses.

Sentiment Analysis:

Overall Tone: Positive

• Management highlighted "greens all across the board" with record revenue, backlog, and gross margins. Strong execution noted across launch and space systems, including record launches and a large SDA contract win. Optimism expressed for future growth, acquisitions, and Neutron progress despite a tank issue, which is seen as a learning opportunity.

Q&A:

• Question from Andreas Shepard (Cantor Fitzgerald): Can you help us drill deeper into the backlog composition, including SDA Tranche 2/3 and Neutron/Electron?
  Response: All SDA contracts are in backlog, with Tranche 2 partially recognized and Tranche 3 entirely un-recognized. Neutron has several flights in launch backlog.

• Question from Andreas Shepard (Cantor Fitzgerald): With Neutron's first launch pushed to Q4 2026, how should we think about cadence, confidence in second tank, and potential step-up in CapEx?
  Response: Second tank production on the AFP machine is faster and lower cost, with no increased CapEx. Follow-on flights will be slightly faster due to ongoing hardware qualification.

• Question from Edison Yu (Deutsche Bank): How are early discussions on space data centers progressing, and could Rocket Lab content be in one within 2-3 years?
  Response: Company is early but has developed silicon solar arrays critical for such projects. Key challenges are launch cost/cadence, heat rejection, and power. No plans to build massive data centers soon, but solutions are compelling for those exploring the idea.

• Question from Alex Preston (Bank of America): How do you see the environment for indigenous European launch and national security space capabilities, and is Europe getting more distant from U.S. providers?
  Response: Sees Europe as a great opportunity and expansion beachhead. Attitude is constructive and pragmatic, with European nations seeking quick solutions, not just sovereign capabilities.

• Question from Eric Rasmussen (Stifel): What is the timing for Neutron's first revenue flight post-test flight, and will it be a recovery mission?
  Response: Timing of Flight 2 depends on Flight 1 results. Vehicle will be outfitted for downrange landing; if successful, next flight will aim for a soft landing.

• Question from Eric Rasmussen (Stifel): What does the manifest suggest for Electron launches in 2026 and the mix between standard Electron and HASTE?
  Response: Expect good growth in both Electron and HASTE, nominally around 20% growth in the launch business excluding Neutron, with production ramped up significantly.

• Question from Trevor Walsh (Citizens): How does the OSI acquisition enhance customer attractiveness and capabilities?
  Response: Owning optics vertically provides certainty on cost, schedule, and innovation, which is critical for delivering customer sensors.

• Question from Trevor Walsh (Citizens): Can you walk through puts and takes influencing SDA Tranche 3 revenue recognition being conservative?
  Response: Revenue recognition is gated by subcontractor deliveries; vertical integration provides more control and predictability, but initial estimates are conservative.

• Question from Ned Morgan (BTIG): Why did Space Systems performance come in weaker than expected, and why might consensus have been ahead?
  Response: Space Systems volatility is due to programmatic non-linearity and subcontractor execution; diversification across launch and Space Systems helps smooth top-line growth.

• Question from Ned Morgan (BTIG): Can you give any financial color on the recent acquisitions and potential cost takeouts?
  Response: Recent acquisitions are strategic for vertical integration and reducing margin stacking, not material revenue contributors. Monarch would be different.

• Question from Guadamcana (TD Cowen): On the Neutron tank failure, are you certain it was due to manual layup, and is the new process safe?
  Response: Failure tree analysis and coupon testing confirmed the manual process defect; confident the AFP machine process will not have the same anomaly.

• Question from Ryan Koontz (Needham & Company): How do you think about backlog composition relative to DOD vs. commercial over the next 12-18 months?
  Response: Pipeline is balanced between commercial and government, but government offers a more predictable "hockey stick". Mix trends favor government but commercial remains important.

• Question from Michael Leshock (KeyBank Capital Markets): Any changes to your approach on a future Rocket Lab satellite constellation?
  Response: It's too early, but there is constant internal discussion. Neutron's online launch capability will be the time to lean into deploying infrastructure.

• Question from Jan Engelbrecht (Baird): What are your high-level thoughts on the PWSA program and the future of the transport layer?
  Response: Intentional to move up the value chain to tracking layer, which is high value. Transport layer seems dedicated; interoperability is key but challenging for different providers.

• Question from Daniel Hibschman (Craig-Hallum Capital Group): How is Rocket Lab's positioning for the Mars Telecommunications Orbiter (MTO) evolving?
  Response: Believes it is well positioned with experience and capabilities, but competition is expected.

• Question from Daniel Hibschman (Craig-Hallum Capital Group): On gross margins, is the Q1 step-down persistent due to SDA mix, or will margins resume expansion later?
  Response: Trends are supportive of gross margin expansion, but quarter-to-quarter volatility is possible due to mix (e.g., SDA programs have lower gross margin but good operating margin). Neutron will follow a margin expansion curve similar to Electron.

Contradiction Point 1

Revenue Recognition Conservatism for SDA Tranche 3

The reason given for a conservative revenue recognition estimate appears to shift between calls.

Can you comment on the earnings results for Citizens as discussed by Trevor Walsh? - Trevor Walsh (Citizens)

2025Q4: RevRec progression is typically ~10% in the first year... The conservative estimate is based on potential delays from third-party subcontractors. - Adam Spice(CFO)

Why is the RevRec for SDA Tranche 3 considered conservative in the first 12 months? - Trevor Walsh (Citizens JMP Securities) - Follow-up

2025Q4: The conservative estimate is based on the timing of deliveries from third-party subcontractors... The company's goal is to accelerate by ensuring subcontractors stay on schedule, which is easier with greater vertical integration. - Adam Spice(CFO)

Contradiction Point 2

Nature of European Launch Ambitions

Characterization of European launch capability development changes from a long-term sovereign goal to a near-term expansion opportunity.

Alex Preston (Bank of America) - Alex Preston (Bank of America)

2025Q4: Europe has ambitions for sovereign capability, but building it quickly is difficult. Rocket Lab sees Europe as a key expansion opportunity—providing components, satellites, and launch services. - Peter Beck(CEO)

Is Europe's growing appetite for indigenous launch and national security space capabilities leading to increased distance from U.S. providers? - Alexander Preston (Bank of America)

2025Q4: Europe has aspirations for sovereign capability but typically lacks the decades needed to build it. Rocket Lab sees Europe as a great expansion opportunity... European nations are pragmatic and often turn to U.S. providers like Rocket Lab when rapid access to orbit is needed, despite investing in their own launch programs. - Peter Beck(CEO)

Contradiction Point 3

Neutron Launch Cadence and Timing

Inconsistent guidance on the planned launch rate for the first year ofNeutron operations.

Could you discuss the company's performance in the quarter and any challenges ahead? - Eric Rasmussen (Stifel)

2025Q4: The goal is to conduct more launches in 2026 than 2025. A reasonable growth estimate is around 20% for the Electron/HASTE launch business (excluding Neutron), with production directed to build more rockets. - Peter Beck(CEO) & Adam Spice(CFO)

What are the plans for Electron launches in 2026, including the mix between standard Electron and HASTE? - Andres Sheppard-Slinger (Cantor Fitzgerald)

20251111-2025 Q3: The cadence is based on a 12-month rate starting from the first launch. The first launch is a test (R&D expense), and subsequent launches will be revenue-generating. The exact timing within 2026 will determine if the full 3 launches fit within the year. - Peter Beck(CEO) & Adam Spice(CFO)

Contradiction Point 4

Neutron Budget and Spending

Contradiction on whether the Neutron program's budget has increased or remains at the original level.

Can you provide an update on the company's financial performance and guidance for the next quarter? - Andreas Shepard (Cantor Fitzgerald)

2025Q4: The second tank cost is low (variable material cost, not CapEx) as the AFP machine is already commissioned. R&D impact from the tank failure is not significant. - Peter Beck(CEO) & Adam Spice(CFO)

With the Neutron first launch now targeted for Q4 2026, how should we think about the launch cadence (e.g., three launches in the first 12 months), and how confident are we in the second tank development and whether CapEx will increase? - Michael Leshock (KeyBanc Capital Markets)

20251111-2025 Q3: The budget has increased. Estimated cumulative spend through end of 2025 is ~$360M. Human capital costs are ~$15M per quarter; the program is approaching peak spending (likely Q4), with timing dependent on the first launch. - Adam Spice(CFO)

Contradiction Point 5

Neutron First Flight Timeline and Risk Posture

Contradiction on whether the first Neutron flight was delayed by the tank issue or if it improved readiness.

Trevor Walsh (Citizens) - Trevor Walsh (Citizens)

2025Q4: The tank anomaly... inadvertently allowed other subsystem teams to complete more testing and reduce overall program risk. - Peter Beck(CEO) & Adam Spice(CFO)

Would the Neutron first flight have met the original Q1 2026 timeline without the tank issue, and were there other factors affecting the schedule? - Michael Leshock (KeyBanc Capital Markets)

2025Q2: The qualification program is complex but the performance is on track. The focus is on ensuring reliability and scalability from the start, even if it means missing arbitrary deadlines. - Peter Beck(CEO)
