Europe's Spectrum Fight Is the Test AST SpaceMobile Has to Pass

Imagine your smartphone holding full 5G broadband in the middle of the Atlantic without a specialized app. AST SpaceMobile builds massive low-Earth-orbit satellites that function as cell towers in the sky. Their BlueBird spacecraft unfurl phased-array antennas stretching up to 2,400 square feet, relaying signals directly to ordinary pocket phones.

AST SpaceMobile is not a consumer brand, and you will never pay them directly for a monthly subscription. Think of the company as a flying cell tower landlord. It sells wholesale connectivity to mobile network operators, letting carriers bill their existing subscribers for coverage in remote dead zones. Today, AST SpaceMobile makes its money selling gateway equipment and hitting government milestones rather than charging commercial phone users.

That wholesale model faced a major test on October 19. Europe’s four biggest mobile operators—Deutsche Telekom, Orange, Telefónica, and Vodafone—signed a Letter of Intent to explore a joint bid for Mobile Satellite Services spectrum. Crucially, the carriers noted that their satellite partner is "still to be selected." AST SpaceMobile was not a signatory to the agreement, though it publicly welcomed the news.

That gap sets up a high-stakes dynamic. Telecom operators want to avoid becoming passive resellers for someone else's closed satellite network, while AST SpaceMobile needs to prove it is the neutral vendor they should hire.

The prize is the European Union's 2 GHz Mobile Satellite Services band. Spectrum is real estate in the airwaves, and this slice provides the optimal physics for satellite direct-to-device service. Unlike narrow emergency channels limited to text alerts, this band has enough room for genuine broadband. Current rights held by legacy players expire in May 2027.

Under a proposal from the European Commission, Brussels plans to divide the band into six paired 5-megahertz blocks, reserving key capacity for an EU newcomer. That reservation matters, because it pushes satellite companies to link arms with local telecom operators.

This is where AST SpaceMobile holds an unusual advantage. In September 2025, the company acquired priority rights from the International Telecommunication Union covering the exact 2 GHz frequencies Europe is preparing to re-allocate. Its satellites can also tune across roughly 1,150 megahertz of carrier frequencies, adapting directly to bands operators already own.

AST SpaceMobile has also built physical roots on European soil. Through Satellite Connect Europe, a joint venture with Vodafone, it is constructing ground stations in Germany, France, Spain, and the UK, alongside a production facility in Barcelona.

The clock is ticking because SpaceX is moving fast. On October 8, SpaceX agreed to acquire Grain Management’s nationwide 800 MHz spectrum portfolio, a deal the Wall Street Journal reported at about $8 billion. Two days prior, U.S. regulators approved a 15,000-satellite direct-to-device Starlink constellation.

SpaceX launches AST SpaceMobile’s satellites while simultaneously building the rival network designed to outrun them. Even carrier alliances are hedging their bets. On October 1, AT&T, Verizon, and T-Mobile launched their own direct-to-device joint venture in the United States, proving telecom giants will not lock themselves into a single satellite provider without leverage.

That uncertainty explains why AST SpaceMobile shares trade down roughly 42% this year and nearly 70% below their May peak. At roughly 141 times trailing sales, the market is pricing the equity like an option on spectrum rights.

For the stock to re-rate, three things must happen in sequence. The company must turn its ground joint venture into a signed European carrier contract. It must accelerate satellite deployment from 13 spacecraft toward the 45 to 60 units needed for continuous coverage. Finally, it must book recurring carrier service revenue rather than one-off gateway receipts.

The bear case centers on a staggering cash burn that leaves little room for manufacturing delays. AST SpaceMobile generated just $31.5 million in second-quarter revenue while spending $622 million on capital expenditures, resulting in negative $719 million of free cash flow.

Pro forma liquidity of more than $3.7 billion provides roughly five quarters of runway at that pace, before accounting for up to $795 million in committed purchase obligations.

Backlog sits at $1.2 billion, but only about 6.6% converts over the next twelve months, leaving full-year guidance of $150 million to $200 million heavily reliant on unbooked business. Share dilution is continuous, with Class A shares climbing 5% in the first half of the year and an $800 million at-the-market program already tapped dry. If SpaceX leverages its owned rockets and acquired low-band spectrum to offer standalone coverage, AST SpaceMobile risks holding billions in debt for an underutilized fleet.

The next checkpoint is whether BlueBirds 14 through 16 leave Cape Canaveral before year-end to prove the launch cadence can keep up with cash burn. The satellites can reach any phone on the ground, but AST SpaceMobile still needs European carriers to flip the switch.
