Aircraft Wi-Fi is carrying the turnaround
- Viasat is shifting satellite capacity from U.S. home broadband to in-flight connectivity.
- The installed commercial aircraft base sits at roughly 4,530, though some planes recently deactivated for competitors.
- Debt remains high at $6.6 billion, making cash flow generation a critical focus for the company.
- U.S. fixed broadband fell to 115,000 subscribers, generating an average of $111 in monthly revenue per user.
- ViaSat-3 Flights 2 and 3 reached the in-orbit test phase, lowering the risk of future capacity shortages.
A pivot with real proof
Viasat is trying to turn a hard satellite story into a cleaner mobility story. The old U.S. home broadband business is shrinking on purpose. The company is using scarce satellite capacity where it sees better returns, mainly aircraft internet. Recent successful deployments for ViaSat-3 Flights 2 and 3 into their in-orbit test phases give the company a clearer path to adding much-needed network capacity.
That plan is working in the data, but facing new friction. Viasat ended the recent quarter with about 4,530 commercial aircraft in service. The company also secured the PTS-G program for its defense segment, proving its military technology has strong momentum. That gives the company a visible growth path if installations keep moving.
The bear case is still serious. Viasat carries $6.6 billion of debt. The market is changing fast as low Earth orbit networks like Starlink win customers with lower-latency service. The company recently confirmed that some commercial aircraft actually deactivated Viasat service to transition to these newer competing providers.
The stock needs steady aviation growth to outpace the intentional decline in home internet. Viasat also needs smooth commercial service starts for ViaSat-3 Flights 2 and 3, plus more debt reduction, to make the turnaround easier to trust.
Selling links in air, sea, and war
Viasat makes money from communications services and from hardware. Services include aircraft Wi-Fi, maritime connections, government satellite communications, and fixed broadband for homes and businesses. Hardware includes terminals, antennas, modems, encryption gear, and other defense technology.
The company reports two segments: Communication Services and Defense and Advanced Technologies. Communication Services is the larger piece and includes aviation, maritime, government satcom, and fixed broadband. Defense and Advanced Technologies sells secure networks, cyber products, space systems, and tactical networking tools.
Most of the revenue is tied to fixed-price contracts. In the last quarter, 96% of revenue came from fixed-price contracts. That can be good when Viasat controls costs, but it can hurt if a project runs late, needs more parts, or takes more labor than planned.
The model breaks if satellite capacity is not enough, if airlines slow installs, if government awards slip, or if LEO rivals force lower prices. It also breaks if cash flow cannot cover interest, satellite spending, and debt paydown at the same time.
What Viasat sells
Commercial aviation IFC
This is the center of the turnaround. Viasat connects aircraft to the internet and had about 4,530 commercial aircraft in service at the end of the recent quarter.
Government satcom
This business provides satellite communication services and products for military and government users. It benefits from demand for secure, mobile connections.
Maritime connectivity
Viasat serves commercial shipping, offshore vessels, and fishing fleets. This area could grow, but it is also exposed to LEO competition at sea.
Fixed broadband
This is the shrinking legacy business, mainly U.S. home internet. Viasat had roughly 115,000 U.S. fixed broadband subscribers at the end of the last quarter.
Information security and cyber defense
Viasat sells encryption and cyber products, including Type 1 and HAIPE-compliant tools used for secure government communications.
Space and mission systems
This line designs satellite systems, modems, terminals, antennas, and related space technology. It gives Viasat exposure to future defense and space programs.
Tactical networking
This business supports mobile military operations with resilient networks for forces in the field. It includes TrellisWare products and the newly won PTS-G program.
Two reported pieces
The mix uses fiscal 2026 revenue. Communication Services was roughly flat, while Defense and Advanced Technologies grew 10% to about $1.34 billion.
What could break
Debt stays too heavy
High impact · Medium oddsViasat ended fiscal 2026 with $6.6 billion of total debt. That still makes cash flow important. If interest costs, satellite spending, or weak revenue eat cash, the turnaround gets harder.
LEO rivals take actual share
High impact · High oddsViasat noted that the traditional GEO satellite industry is losing ground to LEO services like Starlink. This threat is now materializing, with Viasat losing some commercial aircraft activations to competing providers.
Satellite problems limit capacity
High impact · Medium oddsViaSat-3 F1 and I-6 F2 suffered issues that cap future capacity. While ViaSat-3 Flights 2 and 3 recently entered test phases, any delays or performance drops in their commercial service starts would hurt growth.
IFC backlog converts too slowly
Medium impact · Medium oddsThe bull case depends on turning the aircraft backlog into active service. Aircraft installs can slip because of airline schedules, maintenance windows, or delays from aircraft makers.
Fixed broadband drag outlasts aviation growth
Medium impact · High oddsThe U.S. fixed broadband business is shrinking by design down to 115,000 subscribers. It becomes a problem if the fixed decline is larger than the aviation gain.
In one breath
Is Viasat the same kind of company as Starlink?
Both sell satellite connectivity, but they use different network models. Viasat has long relied on GEO satellites, which sit far above Earth, while Starlink uses many LEO satellites closer to Earth.
Why is Viasat shrinking its home broadband business?
The company has limited satellite bandwidth. It is choosing to use more of that capacity for in-flight connectivity, where management sees better long-term returns.
What would make the Viasat turnaround more believable?
Watch for more aircraft installs, steady aviation service revenue growth, successful ViaSat-3 F2 and F3 service starts, and more debt reduction. Those would show that the strategy is working beyond the headline aircraft count.
