AST SpaceMobile is building a proprietary satellite network designed to connect directly to standard smartphones without hardware modifications.
Space Exploration Technologies dominates the launch market while scaling its Starlink broadband service to millions of global subscribers.
Which space-based player deserves a spot in your portfolio in 2026?
The race to provide global satellite connectivity is heating up as space-based networks move from concept to commercial reality. Choosing between AST SpaceMobile (NASDAQ:ASTS) and Space Exploration Technologies (NASDAQ:SPCX) requires weighing infrastructure versus integration.
AST SpaceMobile focuses on connecting standard smartphones directly to its satellite constellation without special hardware. In contrast, Space Exploration Technologies, known on the street as SpaceX, leverages its own reusable rockets to deploy the massive Starlink broadband network. While both target the frontier of global communication, their business models and financial scales differ significantly for investors.
AST SpaceMobile competes among communication stocks by partnering with global mobile network operators to provide satellite-based services. Its primary strategy involves using a proprietary satellite constellation to provide connectivity to standard smartphones without hardware modifications. According to its latest annual report, filed for FY 2025, the company has secured agreements with over 50 partners, including AT&T Inc (NYSE:T) and American Tower Corp (NYSE:AMT). Customer concentration like this adds a layer of risk to the business.
In FY 2025, revenue reached approximately $70.9 million, a substantial jump from the $4.4 million reported in the prior fiscal year. The company reported a net loss of nearly $342 million for the period. While revenue growth is accelerating as the company begins its commercial rollout, profitability remains a distant goal during this build-out phase.This resulted in a net margin of negative 482%, illustrating the high costs associated with launching a satellite constellation before reaching full operational scale.
The current debt-to-equity ratio is roughly 1.2x, showing the company relies more on debt than equity to fund its operations. Based on the December 2025 balance sheet, the so-called current ratio is roughly 16.4x. This indicates a high level of liquid assets relative to near-term liabilities. Free cash flow, which is cash flow from operations minus capital expenditures, was more than negative $1.1 billion for FY 2025, as the firm invested heavily in its proprietary manufacturing and launch capabilities.
Space Exploration Technologies operates a vertically integrated business that designs, manufactures, and launches its own rockets and satellites. The company generates revenue through its Starlink broadband service, which serves millions of subscribers across the consumer, enterprise, and government markets. It currently serves customers in 164 countries and territories, utilizing its proprietary launch capabilities to expand its orbital constellation.
In FY 2025, revenue reached nearly $18.7 billion, which is a growth of roughly 33% over the previous fiscal year. The company reported a net loss of close to $4.9 billion, resulting in a net margin of roughly negative 26%. This loss follows a profitable year in 2024, highlighting the variable nature of heavy capital investment in the aerospace sector.
As of its December 2025 balance sheet, the current ratio is approximately 1.4x. The debt-to-equity ratio is nearly 0.6x, indicating that the company uses less debt relative to equity compared to its peer. Free cash flow was approximately negative $14 billion, and stock-based compensation (SBC) represented roughly 29% of operating cash flow, which inflates reported cash generation since SBC is a non-cash expense added back in the cash flow statement.
AST SpaceMobile faces significant risks regarding its financial viability and ongoing capital requirements. The company has a history of losses and has not yet generated revenue from its core SpaceMobile Service, leading to potential shareholder dilution if more funding is needed. Operational execution is also critical, as the service depends on the successful launch and performance of a complex satellite constellation. Furthermore, the company faces intense competition from established providers like Starlink.
Space Exploration Technologies operates in the high-risk aerospace industry, where launch failures or technical setbacks can cause significant financial and reputational damage. The company is subject to intense regulatory scrutiny and must maintain a high cadence of successful launches to sustain its Starlink expansion. Competition is also a factor, as the company faces pressure from other satellite providers such as Iridium Communications (NASDAQ:IRDM) and Viasat Inc (NASDAQ:VSAT).
Space Exploration Technologies appears more reasonably priced based on its P/S ratio and Forward P/E relative to its larger revenue base.
| Metric | AST SpaceMobile | Space Exploration Technologies |
|---|---|---|
| Forward P/E | n/a | 196x |
| P/S ratio | 153x | 66x |

SpaceX's various businesses intend to leverage the company's core launch capabilities, starting with reusable rockets. The ability to reuse boosters significantly lowers per-launch costs and spreads fixed manufacturing costs across multiple missions. Expectations are that scaling up quickly will happen, with Wall Street analysts projecting $39 billion in sales for fiscal 2026, a much lower net loss of around $1.6 billion, and profitability in 2027.
The lack of free cash flow appears to be crushing; projections indicate free cash flow will be negative $28 billion this year, then jump to negative $67 billion in 2027.
Still, the success of Tesla Inc (NASDAQ:TSLA) has made founder Elon Musk the richest man in the world and raised expectations that he can make an even greater fortune from SpaceX. The business certainly has market support behind it, raising the world's largest IPO, $85.7 billion this year.
SpaceX has a very real business in Starlink, which mitigates the possibility that grander plans won't come to fruition.
AST SpaceMobile expects its space-based network to give it a significant business in a few years. Essentially, AST SpaceMobile is a direct-to-device play to provide full mobile phone compatibility for major carriers without the need for specialized equipment. Many of its potential clients are also equity holders in the company, including AT&T, Verizon Communications (NYSE:VZ), Bell Canada, Rakuten, Vodafone (NASDAQ:VOD), Alphabet Inc (NASDAQ:GOOGL), American Tower, and Telus (NYSE:TU).
By the end of 2026, the company should have 45 satellites, which will allow it to fully service the U.S., and that should start to supercharge revenue growth. For fiscal 2026, Wall Street sees $149 million in sales, jumping to $725 million the following year, when the company is projected to turn its first modest profit. Free cash flow appears much more manageable, with analysts expecting positive free cash flow in 2029.
In choosing between the two, the major telecom businesses backing AST SpaceMobile lend confidence that the company's plans will pan out over the long term. Meanwhile, SpaceX's mission appears muddled: is it a telecom provider, a space cargo business, or a Mars colonization outfit?
The better bet for 2026 is AST SpaceMobile.
