AST SpaceMobile Faces Twin Tests: Viasat's FCC Challenge and a Wall Street Divide Over Execution

AST SpaceMobile's path to commercial service now runs through two separate gates — one regulatory, one operational — and the market is pricing both at once. Viasat has asked the U.S. Federal Communications Commission to reject the company's application for additional foreign spectrum, while analysts remain sharply divided over whether a recent selloff reflects a genuine competitive threat or a misread of the company's position.

The stock's 31% decline over 30 days frames the debate. AST has flagged progress toward an initially intermittent mobile broadband service, targeted to launch before the end of 2026 in the U.S., Canada, Japan, the U.K. and Saudi Arabia. That timeline carries a regulatory caveat, and the company has explicitly stopped short of promising continuous coverage at the outset.

A Spectrum Fight at the FCC

Viasat's filing argues that AST's request overlaps with existing satellite services and seeks frequencies that are not available for the proposed operation. AST submitted the application in July; the FCC accepted it for review in September — a procedural step, not an approval. The company has said it will obtain national authorizations before operating abroad and plans technical measures to limit interference.

The distinction matters for investors weighing the geographic build-out. Without the necessary frequency approvals, engineering milestones cannot automatically translate into wider service. AST's own expansion plans remain expressly conditional on regulatory clearance.

Two Analysts, Two Readings

Wall Street's split came into focus on October 12, when Deutsche Bank upgraded AST SpaceMobile from Hold to Buy while keeping its $93 price target. Analyst Bryan Kraft characterized the preceding selloff as a market misinterpretation. Piper Sandler had moved the other way about a week earlier, cutting the stock from Overweight to Neutral and slashing its price target from $98 to $54. Analyst Alexander Potter cited reduced confidence in the launch pace for 2026–2027 and competition from SpaceX.

That competitive worry traces to October 8, when SpaceX agreed to acquire Grain Management's nationwide 800 MHz spectrum portfolio for Starlink Mobile. The deal is subject to FCC approval and is not a completed takeover. Deutsche Bank's counterargument is that the move does not make SpaceX a stronger competitor to AST as a provider to its mobile partners — a distinction between building out proprietary spectrum resources and holding a position inside existing partner relationships.

Infrastructure Is Not Coverage

The operational question is how long a connection is actually available. Early on, service depends on whether satellite coverage exists at a given moment; additional satellites are meant to extend both the duration and frequency of that coverage. More than 60 gateways are installed, in operation or planned worldwide, and over 3,000 mobile cells are already activated in the U.S. Those figures describe different stages of build-out and do not prove continuous service.

BlueBird production, according to the company, has reached unit 50 — a signal of manufacturing momentum, not of satellites already in orbit. The partner ecosystem spans more than 60 mobile operators with over 3 billion subscribers combined, though that reach is not equivalent to paying customers of the satellite service.

A European Opening, Without a Supplier

A possible European angle has emerged: Deutsche Telekom, Orange, Telefónica and Vodafone are exploring a joint bid for future European satellite spectrum. The joint venture Satellite Connect Europe is building European-operated ground infrastructure to link satellites with mobile core networks. AST welcomed the initiative, pointing to its European-operated ground infrastructure and BlueBird satellites.

No satellite provider has yet been selected for the potential joint bid, and the declaration contains no supplier commitment to AST. A firm order cannot be inferred from it.

What the Year-End Deadline Really Tests

The next concrete checkpoint is the targeted service launch before the end of 2026 — with no specific day attached. Investors would be better served watching the conditions around any launch: where service is authorized, when it becomes available, and how coverage develops. If the schedule holds and additional satellites widen the available connection windows, today's preparation could prove durable progress. If the timeline slips or coverage stays severely constrained for longer, expectations for the build-out would need reassessment. The investment case rests less on the existence of a launch target than on whether AST can turn prepared infrastructure and partner relationships into an increasingly reliable service.
