Key Takeaways
- Rocket Lab achieved 38% revenue growth reaching $601.8 million in 2025, supported by a record-breaking $1.85 billion backlog
- An $816 million Space Development Agency contract solidified Rocket Lab’s position in government aerospace projects
- AST SpaceMobile generated $70.9 million in 2025 annual revenue while advancing its commercial satellite infrastructure
- AST maintains robust pro forma liquidity exceeding $3.9 billion to support ongoing satellite launches
- Analyst sentiment favors Rocket Lab with a Moderate Buy rating, while AST receives a Reduce consensus
In the expanding space technology sector, Rocket Lab and AST SpaceMobile represent two compelling yet fundamentally different investment opportunities. These companies pursue distinct strategies with varying levels of risk and reward. One has established a proven, multi-faceted operation. The other pursues an ambitious vision that could revolutionize global mobile communications.
Rocket Lab delivered impressive financial results throughout 2025. The company reported revenue growth of 38%, totaling $601.8 million for the year. Its fourth-quarter performance was particularly noteworthy, achieving record revenue of $179.7 million. Perhaps most significantly, Rocket Lab closed the year with a $1.85 billion backlog—a 73% year-over-year increase. This substantial backlog provides greater revenue visibility compared to many competitors in the space industry.
The company’s evolution extends far beyond its launch service origins. In 2025, product sales generated $371.6 million while services contributed $230.2 million. Today, Rocket Lab manufactures spacecraft, specialized components, and integrated systems primarily for defense and national security applications.
Strong Government Partnerships Provide Rocket Lab with Revenue Stability
A significant milestone came when Rocket Lab secured an $816 million agreement with the Space Development Agency. This substantial contract demonstrates the company’s credibility for executing complex, extended-duration government programs. Meanwhile, its Neutron medium-lift launch vehicle represents management’s primary focus for driving the next phase of expansion.
However, profitability remains elusive. Rocket Lab recorded a net loss of $198.2 million throughout 2025. Company executives have also projected continued adjusted EBITDA losses for the opening quarter of 2026. Current valuations reflect investor confidence in future operational scale rather than present-day profitability.
AST SpaceMobile pursues an entirely different approach. The company’s mission centers on deploying a space-based cellular broadband infrastructure capable of connecting directly with ordinary smartphones—eliminating the need for specialized equipment. Successfully executing this vision at scale could unlock underserved markets worldwide that conventional satellite providers cannot efficiently address.
AST remains in the early stages of this ambitious undertaking. The company reported full-year 2025 revenue of $70.9 million. Fourth-quarter results showed particularly strong performance at $54.3 million, primarily generated through gateway equipment deliveries, partnerships with mobile network operators, and achieving government-related milestones.
Substantial Cash Reserves Provide AST SpaceMobile Development Runway
At the conclusion of 2025, the company maintained $2.8 billion in cash and cash equivalents. Following additional capital raises in early 2026, pro forma liquidity surpassed $3.9 billion. This financial cushion enables AST to continue satellite deployment initiatives without facing near-term funding constraints.
AST has also secured more than $1.2 billion in contracted revenue commitments from strategic partners. For a company that recently commenced commercial operations, this represents substantial validation. Nevertheless, the company continues reporting significant losses, and ultimate success hinges on deployment velocity and network reliability.
Analyst perspectives clearly reflect these fundamental differences. Rocket Lab maintains a Moderate Buy consensus rating, comprising 2 Strong Buys, 7 Buys, 7 Holds, and 1 Sell recommendation. Conversely, AST SpaceMobile carries a Reduce consensus, with 2 Buys, 6 Holds, and 3 Sell ratings.
Final Thoughts
The analyst community demonstrates greater confidence in Rocket Lab’s established business model. While AST’s potential upside is acknowledged as genuine, its current stage makes valuation more challenging for traditional analysis. Rocket Lab presents a more mature enterprise with diversified revenue streams, proven execution, and broader analyst endorsement. AST represents a higher-risk proposition with substantially greater potential returns if its satellite broadband architecture achieves commercial success.
Rocket Lab offers the more established investment case at present. AST SpaceMobile embodies the more ambitious technological vision. The appropriate choice between these two space stocks depends entirely on individual risk tolerance and investment objectives.
