Performance Analysis
Intuitive Machines delivered sequential revenue growth of 14% in Q1 2025, reaching $62.5 million, led by execution in CLPS (Commercial Lunar Payload Services), LTDS (Lunar Terrain Vehicle Services), and NSNS (Near Space Network Services). The company’s gross profit improved to $6.7 million, marking a third straight quarter of positive gross margin and underscoring progress in operational efficiency and program mix. BOEM, the company’s orbital servicing segment, contributed $21.7 million, reflecting ongoing work on the OSAM (On-orbit Servicing, Assembly, and Manufacturing) project and new commercialization studies for the Space Force.
Free cash flow turned positive for the first time at $13.3 million, supported by milestone receipts for IM3, IM4, and LTV, and a $148 million cash infusion from warrant redemption. SG&A rose seasonally due to incentive compensation, while adjusted EBITDA improved by $4.6 million versus Q4, trending toward breakeven by year-end. The cash balance surged to $373.3 million, with no debt and a new $40 million credit facility untapped. Backlog ended at $272.3 million, with 45% to 50% expected to convert in 2025 and major new awards anticipated in the second half.
- Margin Expansion: Higher margin service businesses, especially NSNS, are beginning to scale, supporting the path to positive adjusted EBITDA.
- Backlog Conversion: Nearly half of the current backlog is slated for recognition in 2025, providing near-term revenue visibility.
- Capital Strength: Over $400 million in available capital positions LUNR for both organic investment and opportunistic M&A.
While program milestone timing continues to drive cash flow lumpiness, management’s focus on recurring services and infrastructure is gradually smoothing the revenue base and improving profitability prospects.
Executive Commentary
"As we anticipated last year, the Artemis campaign is evolving. Nominated NASA Administrator Jared Isaacman has articulated a bold dual-track vision to pursue lunar and Martian exploration with Artemis as a stepping stone. We believe this vision, reinforced by the President's recent NASA budget request, signals continued support for deep space initiatives that Intuitive Machines is built to serve."
Steve Altomus, Chief Executive Officer
"We kicked off 2025 with a strong first quarter, with revenues and gross margin up sequentially... We continue to drive consistent and higher profitability through efficient program execution and a focus on higher margin service businesses. This marks our third consecutive quarter of positive gross margins."

Strategic Positioning
1. Multi-Pillar Space Economy Model
Intuitive Machines structures its business around three pillars: delivery services, data services, and infrastructure services. Delivery encompasses lunar landers, rideshare, and orbital transfer vehicles; data services include lunar data relay and navigation (NSNS); infrastructure covers surface mobility and power (LTV, nuclear propulsion). This model enables LUNR to address the full value chain of lunar and cislunar commerce, with a growing emphasis on recurring, service-based revenue streams.
2. Diversification into National Security and Earth Reentry
Recent contract wins in stealth satellite, orbital transfer vehicles, and a $10 million Texas Space Commission grant for Earth reentry vehicle development highlight LUNR’s pivot beyond NASA-centric projects. The reentry program leverages proprietary soft-landing technology for precision payload return, targeting commercial and defense customers and positioning the company as a multi-domain infrastructure provider.
3. Technical Differentiation and Operational Learning
IM2’s partial success yielded unique operational data from the lunar south pole, enabling rapid iteration for IM3. The company is investing in redundant altimeters, lighting-independent sensors, and machine learning-enhanced navigation. This cycle of flight, review, and redesign is hardening LUNR’s technical edge and credibility in high-risk, high-reward lunar operations.
4. Government Alignment and Policy Tailwinds
Federal budget signals and NASA’s evolving Artemis priorities provide visibility into future funding and contract flow. LUNR’s testimony before Congress and collaboration with national security stakeholders reinforce its standing as a preferred commercial partner for both civil and defense space initiatives.
Key Considerations
The quarter demonstrated LUNR’s ability to execute across multiple programs while navigating the complexity of government-driven demand cycles. The company’s capital position and backlog provide a strong foundation, but the next phase will depend on scaling service revenues and capitalizing on new contract awards.
Key Considerations:
- Transition to Recurring Revenue: NSNS and lunar data relay services are critical for margin expansion and long-term stability as milestone-driven delivery revenues remain lumpy.
- Operational Resilience: IM2’s lessons are being rapidly applied to IM3, with technical upgrades and enhanced testing mitigating risk for future missions.
- Backlog Visibility: Execution on $272 million in backlog and conversion of recent awards will determine near-term revenue realization.
- M&A Optionality: With no debt and significant cash, LUNR has flexibility to pursue strategic acquisitions aligned with its three-pillar model.
Risks
Program milestone timing and contract closeouts remain unpredictable, leading to potential revenue and cash flow lumpiness. Dependency on government budgets and evolving NASA priorities introduces funding and award timing risk, while technical setbacks on high-profile lunar missions could impact credibility and cost structure. Competitive dynamics in data relay and infrastructure, especially as European and other entrants emerge, may compress margins or slow adoption.
Forward Outlook
For Q2 2025, Intuitive Machines expects:
- Recognition of IM2 success payments and additional NSNS milestone revenue
- Continued sequential revenue growth from backlog execution
For full-year 2025, management maintained guidance:
- Revenue of $250 million to $300 million
- Positive run-rate adjusted EBITDA by Q4 2025 and full-year positive adjusted EBITDA in 2026
Management highlighted several factors that will shape results:
- Timing of new contract awards, particularly in CLPS, LTV, and NSNS
- Scaling of higher-margin, service-based revenues to offset milestone lumpiness
Takeaways
LUNR’s first positive free cash flow quarter marks a pivotal operational milestone, but sustaining this performance will depend on execution in upcoming lunar, data, and infrastructure programs.
- Margin Trajectory: The shift toward NSNS and recurring services is starting to lift margins, but scale and contract wins will determine durability.
- Strategic Breadth: Expansion into national security and Earth reentry diversifies the opportunity set, reducing reliance on NASA alone.
- Future Watchpoint: Investors should monitor backlog conversion, major contract awards in the second half, and the pace of recurring revenue ramp as key drivers for 2025-2026.
Conclusion
Intuitive Machines is executing against a diversified strategy, leveraging technical learning and government alignment to build a multi-domain space infrastructure business. With a strong capital base and improving profitability, the company is positioned to capitalize on new government and commercial opportunities, but must demonstrate sustained revenue and margin growth as milestone-driven volatility persists.
