AST SpaceMobile vs. Intuitive Machines: Which Space Infrastructure Stock Is a Better Buy in 2026?

Intuitive Machines is presented as the more attractive 2026 space-infrastructure investment, trading at a 1.3x price-to-sales ratio versus AST SpaceMobile's 149x despite expected fiscal-2026 revenue growth to $952 million from record first-quarter revenue of $187 million and a $1.1 billion backlog. AST SpaceMobile reported FY2025 revenue of $70.9 million, up roughly 1,500%, but posted a $342 million net loss and negative $1.1 billion free cash flow; analysts forecast 2026 sales of $149 million and $725 million in 2027 as its constellation expands to 45 satellites. Both companies remain capital-intensive and loss-making, with AST facing litigation and direct-to-cell competition, while Intuitive Machines remains exposed to NASA funding concentration and lunar-mission execution risk.

Analysis

The valuation gap is less a simple bargain signal than a difference in revenue quality and funding risk. LUNR’s rerating requires converting contracted work into cash without mission losses or working-capital stress; backlog alone should not receive a full multiple until milestones, margins, and payment terms are visible. ASTS, conversely, is priced on a narrow execution path: satellite deployment, spectrum/regulatory clearance, carrier activation, and proof that wholesale economics support recurring service revenue before another major capital raise.

For the next 1-3 months, LUNR has the cleaner fundamental catalyst path if quarterly bookings convert to funded awards and management raises revenue or cash-burn guidance. ASTS is more vulnerable to a downside air pocket if deployment cadence slips, carrier commercialization is delayed, or litigation produces adverse disclosure-related developments; its valuation leaves little cushion for a one- or two-quarter delay. The key falsifier for relative-long LUNR is a material mission anomaly, cancellation/deferral of a major government award, or deterioration in operating cash flow despite reported revenue growth.

Consensus may underappreciate that direct-to-device is initially complementary to terrestrial networks, not an immediate tower replacement: T and VZ can reduce rural coverage gaps without absorbing full network-build costs, while AMT’s exposure is a longer-dated rural densification risk rather than an earnings event. Over 6-18 months, the more important ASTS competitive variable is whether SpaceX’s direct-to-cell offering commoditizes basic messaging/coverage, forcing ASTS toward a lower wholesale take rate even if demand materializes. LUNR’s apparent cheapness can also be illusory if revenue is dominated by low-margin pass-through hardware and subcontractor content.

Key Decisions for Investors

• Initiate a 1-3 month relative-value position: long LUNR / short ASTS, sized beta-neutral and modestly given high short-interest/squeeze risk in ASTS. Target 20-30% relative return if LUNR confirms cash conversion and ASTS guidance/deployment risk persists; exit if LUNR loses a material award or ASTS demonstrates commercial service activation with improved funding visibility.
• Own LUNR only through the next earnings/cash-flow update if receivables, contract assets, and operating cash flow validate reported revenue. Add on evidence of positive gross-margin progression and funded bookings; avoid adding solely on backlog headlines.
• Avoid unhedged ASTS longs ahead of deployment and financing updates. For investors requiring upside exposure, use defined-risk call spreads dated beyond the next major satellite/service milestone rather than equity; the missing diligence item is the fully funded constellation capex plan and expected carrier revenue-share structure.
• Monitor AMT as a 6-18 month second-order watch item rather than a near-term short. Reassess rural tower-growth assumptions only if direct-to-device services expand from emergency/messaging coverage into meaningful broadband substitution and carriers explicitly reduce rural tower leasing or build plans.
