Vertical Integration Across the Entire Space Stack Rocket Lab operates from launch through spacecraft production and now communications hardware. Electron — its small-lift rocket — completed nearly three dozen successful missions and generated $199 million in launch services revenue in 2025 , with average revenue per launch rising to $8.5 million from $7.8 million the prior year. Space Systems contributed the larger share at $402.8 million, or 67% of total revenue. That’s a fancy way of saying the company captures value at multiple layers instead of handing off work to suppliers. Gross margins expanded to a record 38% GAAP in the fourth quarter, up 780 basis points year-over-year and 100 basis points sequentially. In short, vertical control helped margins rise even as the company scaled both launch cadence and satellite manufacturing. The company posted record full-year 2025 revenue of $602 million, up 38% from the year prior, while Q4 revenue reached $180 million, a 36% increase and above consensus estimates of roughly $178 million. Backlog expanded 73% to $1.85 billion, with about 37% expected to convert to revenue in the next 12 months. That visibility sets Rocket Lab apart from many peers still chasing funding rounds rather than contracts. Adding to the Arsenal Last week, Rocket Lab received regulatory approval from Germany’s Federal Ministry for Economic Affairs and Energy to acquire Mynaric , a provider of laser optical communications terminals. The deal, first announced in 2025 with an initial value around $75 million plus performance-based payments, is set to close this month. Mynaric will remain based in Munich, giving Rocket Lab its first dedicated European presence and in-house high-bandwidth data links for satellites. This addition completes more of the stack. Laser comms move data far faster than radio systems, addressing a key need for both commercial constellations and defense networks. Customers can now turn to one vendor for launch, spacecraft build, and connectivity. The Upside of Owning the Full Space Stack Def ense contracts now anchor a meaningful portion of growth. In December, the U.S. Space Development Agency awarded Rocket Lab an $816 million prime contract — its largest to date — to build 18 missile-warning and tracking satellites for Tracking Layer Tranche 3. Last month, it added a $190 million contract with the War Dept. for 20 hypersonic test flights using its HASTE launch vehicle. Electron’s operations from New Zealand and Virginia support responsive launch needs for smaller payloads, including national security missions that require speed and compliance with export rules. Space Systems revenue outpaced launch in 2025, showing the model already delivers diversified income. Neutron, the medium-lift reusable rocket, targets larger constellations and higher-margin missions. A propellant tank failure during January testing delayed the first launch to no earlier than Q4. Management identified manufacturing fixes and expects R&D spending to peak in the first quarter. That said, the delay carries clear execution risk, with cumulative Neutron investment already notable. Success would expand the addressable market without cannibalizing the profitable Electron franchise. No matter how you slice it, Rocket Lab’s end-to-end capabilities, proven Electron performance, expanding defense role, and Mynaric integration create a differentiated profile heading into the SpaceX IPO wave. The Risks That Make the Reward Yet, the company still reports losses. Full-year 2025 produced a net loss, with Q4 GAAP EPS at a $0.09 loss. Guidance for Q1 calls for revenue of $185 million to $200 million. Analysts see breakeven potentially arriving in 2027 or later. Smart investors balance that against Rocket Lab’s $2 billion backlog and 38% revenue growth that outpaced many smaller launch peers hampered by funding gaps. Launch delays or shifts in government spending could also pressure results. Shares trade at premium valuations reflecting growth expectations, though the numbers show a business generating real revenue and backlog while peers scramble. In any case, with sector attention rising, Rocket Lab offers retail investors exposure to a vertically integrated player delivering today — and positioned for larger missions tomorrow. Key Takeaway Instead of buying a basket of space stocks, focus on just one anchored in vertical integration across launch, spacecraft, defense, and communications. Rocket Lab’s $602 million annual revenue, $2 billion backlog, mounting military wins, and a just-approved Mynaric deal provide concrete progress. While investors need to monitor its Neutron execution and quarterly conversion of backlog, taking a position today gives you skin in the game with a proven winner. SpaceX’s IPO may be worth buying into when it finally goes public, but Rocket Lab is delivering real-world results today. About the Author
