AST SpaceMobile (NASDAQ: ASTS): Direct-to-Smartphone Satellite Broadband

Who they are

Abel Avellan founded AST SpaceMobile in 2017 after selling his previous satellite communications company, and the premise has not changed since: build satellites with antennas large enough that an ordinary phone — with its tiny antenna and modest transmit power — can close the link on its own. Everything else about the company follows from that one engineering choice.

It is a demanding choice. A phone cannot shout very loudly, so the satellite has to listen very carefully, which means an enormous phased-array antenna. AST's Block 1 BlueBirds already used the largest commercial communications arrays ever flown in low Earth orbit. The Block 2 satellites are roughly three times larger again — arrays of about 2,400 square feet — and unfolding one of those in orbit is a genuinely non-trivial piece of mechanical engineering.

The company listed on the Nasdaq in 2021 via a SPAC merger and has since raised capital repeatedly to fund the constellation. It employs more than 2,250 people, runs over 500,000 square feet of manufacturing and operations space, and holds a patent portfolio with roughly 3,900 granted and pending claims. Manufacturing is about 95% vertically integrated, including a dedicated Texas facility producing the "microns" — AST's ASIC processors — at a rate supporting more than ten satellites' worth per month.

What they do

AST does not sell to consumers. It sells to mobile carriers, who resell space-based coverage as an extension of their own networks — which is why the partner list is the asset that matters most.

Those partners now number close to 60 operators covering over three billion subscribers, including AT&T and Verizon in the US, Vodafone, Rakuten, Bell Canada and Telus in Canada, and Orange, MTN, Vodacom and Axian Telecom across Africa. The company has also secured over $1.2 billion in aggregate contracted revenue commitments from partners, and holds contracts with the US government.

The regulatory milestone came in early 2026, when the FCC authorised commercial SpaceMobile Service in the United States through a Supplemental Coverage from Space grant covering a network of up to 248 satellites. That is the permission slip that turns demonstrations into a business.

Deployment has accelerated sharply. BlueBird 6 launched in December 2025 from India, BlueBird 7 on Blue Origin's New Glenn in April 2026, BlueBirds 8–10 on a Falcon 9 in June 2026, and BlueBirds 11–13 on another Falcon 9 on 5 August 2026. Production is advancing through satellite 42, with BlueBirds 14, 15 and 16 preparing for the next mission. The stated target is 45 to 60 satellites in orbit by the end of 2026, with launches roughly every one to two months.

On performance: a Block 1 BlueBird hit a peak of 98.9 Mbps directly to an unmodified smartphone over international waters. The Block 2 satellites are expected to roughly double that, approaching 200 Mbps.

How they make money

Three revenue lines, at very different stages of maturity.

• Gateway hardware — AST sells the ground gateways its carrier partners need to connect the satellite network to their terrestrial cores. Fifteen commercial gateways were delivered across nine customers on five continents in the second half of 2025 alone. This is real revenue today, but it is one-time equipment revenue, not the eventual business model.
• US government contracts — service revenue tied to milestones across multiple programmes.
• Carrier revenue share — the actual long-term model, in which mobile operators pay AST for the space-based coverage they resell to subscribers. This is the line that has barely started.

The numbers reflect that sequencing. AST went from pre-revenue to $70.9 million of revenue in 2025, most of it concentrated in a $54.3 million fourth quarter driven by gateway deliveries and government milestones. Q1 2026 revenue was $14.7 million against total operating expenses of $164.1 million. The company has reaffirmed 2026 revenue guidance of $150 million to $200 million.

Capital consumption is the other half of the picture: Q4 2025 capital expenditure alone was roughly $407 million, up from about $259 million in Q3, spent on Block 2 satellite materials and launch contracts. Against that, cash stood at approximately $3.5 billion as of 31 March 2026. This is a company converting a very large balance sheet into orbital hardware at speed.

Where it sits in the value chain

AST sits in Stage 5: Satellite Communications & Broadband, but it reaches backwards through the chain more than most operators. Because it builds its own satellites in-house — arrays, processors and all — it also performs the work of Stage 2 and Stage 3, and because it manufactures and sells the carrier gateways, it touches Stage 4 as well.

What it deliberately does not do is launch. AST buys rides from SpaceX, Blue Origin, and ISRO, which puts it in the mildly awkward position of paying its most direct competitor to deploy the constellation competing with Starlink's direct-to-cell service. That is currently a fact of life for anyone building in this segment.

The bigger trend

Direct-to-device is the first satellite application in decades with a genuinely consumer-scale addressable market, and the reason is that it removes the hardware barrier. Every previous satellite service required buying something — a phone, a dish, a terminal. This one requires buying nothing, which means the market is not "people who want satellite service" but "people with phones."

The strategic prize is coverage economics. Terrestrial cell towers cover a small fraction of the planet's surface because towers are only worth building where people are dense enough to pay for them. Satellites invert that: the marginal cost of covering an empty ocean is zero. For a mobile carrier, satellite coverage is a way to claim complete national coverage without building anything.

The competitive field is now crowded, and it is splitting by spectrum strategy. SpaceX's Starlink Direct to Cell is ahead on commercial deployment and, following its purchase of EchoStar's AWS-4 and H-block licences, now controls dedicated spectrum for the service. Globalstar supports Apple's satellite features. Viasat and others are pursuing shared-infrastructure models. AST's differentiator is bandwidth — it is targeting genuine broadband rather than text messaging — but broadband requires enormous antennas, which is why its satellites are so much larger and its capital requirements so much heavier than the alternatives.
