Rocket Lab Soars
Rocket Lab USA reported record figures for the fourth quarter and full year 2025.
Dear Growth Investors,
Rocket Lab Soars to Record Heights in Q4 2025 Earnings, Eyes Neutron Debut in 2026.
Rocket Lab released its Q4 and full-year 2025 earnings on February 26, 2026, showcasing remarkable growth amid ongoing investments in its ambitious Neutron rocket program. Despite a delay in Neutron’s first launch to Q4 2026 due to a manufacturing setback, the company reported record-breaking revenue, backlog, and margins, underscoring its strengthening position in the space industry.
Financial Performance: Record Revenue and Margin Expansion
For the full fiscal year 2025, Rocket Lab achieved a record annual revenue of $602 million, marking a 38% increase year-over-year from 2024. This growth reflects a four-year compound annual growth rate (CAGR) of 76.3%, driven by heightened launch cadence and expansion in the space systems segment.
In Q4 2025 alone, revenue reached $180 million, up 36% from Q4 2024 and 16% sequentially from Q3 2025. The company attributed this to an increase in Electron launches, from 4 to 7 quarter-over-quarter, and robust performance in space systems, including contributions from the newly awarded SDA Tranche III Tracking Layer contract.
Gross margins also hit new highs: GAAP gross margin stood at 38% for Q4, while non-GAAP gross margin reached 44.3%. Annual gross margin expansion on both GAAP and non-GAAP bases demonstrates operational efficiencies, with the company progressing toward its target business model despite heavy R&D investments in Neutron.
Operating expenses rose year-over-year, with GAAP and non-GAAP SG&A increasing due to higher staff costs, the Geost acquisition impact, and compliance efforts for U.S. government programs. R&D expenses surged, primarily from Neutron development, including Archimedes engine testing and composite structures. However, SG&A declined quarter-over-quarter, reflecting reduced legal and marketing costs.
Cash position remained strong at $1.1 billion in cash, cash equivalents, marketable securities, and restricted cash. GAAP EPS showed a loss of $(0.09) per share, widened by the absence of a one-time tax benefit from Q3. Adjusted EBITDA loss improved to $(17.4) million from $(26.3) million in Q3, buoyed by revenue growth and margin gains. Non-GAAP free cash flow was $(54.7) million, with capital expenditures up to $49.7 million for Neutron infrastructure.
The backlog ballooned to $1.85 billion by year-end, a 73% increase from Q4 2024 and 69% from Q3 2025, largely fueled by the $816 million SDA contract. Approximately 37% is expected to be recognized in the next 12 months, with the rest beyond.
Business Highlights: Launches, Missions, and Acquisitions
Rocket Lab’s Electron rocket continued its dominance in the small launch market, completing 21 launches in 2025, a new annual record, with 100% mission success. Q4 saw 7 launches, the highest quarterly total yet, including three HASTE (Hypersonic Accelerator Suborbital Test Electron) missions supporting U.S. Department of Defense hypersonic testing priorities. The company signed over 30 new launch contracts, diversifying across U.S. national security, defense, commercial constellations, and allied governments. Notable deals include a 4x launch agreement with BlackSky and a contract with a new confidential national security customer.
In space systems, Rocket Lab secured its largest-ever contract: an $816 million award from the Space Development Agency (SDA) to build and install 18 advanced missile warning satellites for the Tranche III Tracking Layer. This positions Rocket Lab as a disruptive “new prime” in national security space, leveraging vertical integration for high-value opportunities.
The ESCAPADE Mars mission, featuring two Rocket Lab-built satellites for NASA and UC Berkeley, achieved full success: on-time, on-budget launch, deployment, commissioning, and trajectory corrections. Control handover to UC Berkeley is slated for next month, paving the way for science operations.
Additionally, Rocket Lab built and is preparing to launch a spacecraft for NASA’s on-orbit cryogenic fueling demonstration, highlighting its rare capability as one of only two U.S. companies able to build and launch spacecraft. The company also introduced Silicon Solar Arrays for space-based data centers, mega constellations, and national security programs.
The market for data processing in orbit is poised for enormous growth in the coming years. It's a multi-billion dollar market. Rocket Lab could be a major player in that field.
What many miss by looking at Rocket Lab, is their $80 million acquisition of solar module manufacturer SolAero in 2021.
SolAero was founded in 1998 and is headquartered in Albuquerque, New Mexico. The company is known for manufacturing high-performance solar cells and modules for satellites and spacecraft.
SolAero has more than 20 years of experience in the design, qualification, and manufacturing of solar cells and CIC/SCA. SolAero’s space solar cells are among the most powerful in the world and support civil space exploration, science, defense, and intelligence.
The company offers a range of space solar products, each specifically designed for missions in low Earth orbit (LEO), medium Earth orbit (MEO), geostationary orbit (GEO), or for interplanetary applications. SolAero’s technology has also enabled commercial satellite constellations and powers OneWeb’s broadband constellation.
The acquisition for $80 million in cash seems almost like a bargain given the future potential.
SolAero in numbers:
• Over 1,000 satellites in orbit are powered by SolAero products.
• 4 MW of solar cells have been manufactured to date.
• 1,000 successful space missions with 100% reliability and mission success.
Strategic acquisitions bolstered capabilities: Geost (August 2025) enhanced mobile payloads for national security; Optical Support Inc. (February 2026) added high-precision optical expertise; and Precision Components Ltd. (Q1 2026) expanded manufacturing for launch and space systems. An acquisition of Mynaric Laser Optics is in progress, pending regulatory approval.
Rocket Lab was selected for the Missile Defense Agency’s SHIELD program with a $151 billion shared contract ceiling, enabling future bids on launch and space systems.
Let’s look deeper into the acquisition of Optical Support, Inc. This move strengthens Rocket Lab’s capabilities in high-precision optical systems, particularly for national security and commercial satellite payloads.

The OSI deal focuses specifically on precision optics and optomechanics for payloads. For the official announcement, see Rocket Lab’s investor relations page.
Neutron Progress: Milestones Amid Delay
Development of the reusable Neutron medium-lift rocket advanced significantly, with key structures like the Hungry Hippo fairing qualified and delivered to Launch Complex 3 (LC-3) in Virginia. The thrust structure, capable of withstanding 2.1 million pounds of thrust, was qualified and is set for Archimedes engine integration. The 13-meter interstage is undergoing qualification, and LC-3 is preparing for Stage 2 testing.
However, a Stage 1 tank rupture during January 2026 testing, caused by a manufacturing defect in a third-party hand-lay process, prompted a switch to automated fiber placement (AFP) production and design changes for added margin. This, combined with an expanded test program, delayed Neutron’s maiden flight from mid-2026 to Q4 2026.
Archimedes engine testing intensified, with twin test cells at Stennis running in parallel to verify performance under extreme conditions.
Outlook: Continued Growth in 2026
For Q1 2026, Rocket Lab projects revenue between $185 million and $200 million, with increases in both Launch and Space Systems. GAAP gross margins are expected at 34%-36%, non-GAAP at 39%-41%. Operating expenses are forecasted at $120-$126 million GAAP and $106-$112 million non-GAAP. Adjusted EBITDA loss is anticipated at $21-$27 million, with interest income of $8.0 million net.
The company emphasized its healthy pipeline for additional 2026 revenue beyond the backlog, including multi-launch deals and large satellite contracts.
Conclusion
Rocket Lab’s 2025 results highlight its evolution from a small-launch specialist to a full-spectrum space company, with vertical integration unlocking high-value defense and commercial opportunities.
