Aircraft Wi-Fi is carrying the turnaround
- Viasat is shifting satellite capacity from U.S. home broadband to in-flight connectivity, or IFC.
- The installed IFC base reached about 4,580 commercial aircraft, with about 1,000 more in backlog.
- Debt fell to $6.6 billion from $7.2 billion a year earlier, but leverage still matters.
- U.S. fixed broadband is now down to about 130,000 subscribers, with $113 in average monthly revenue per user.
- The new risk is clear: LEO networks like Starlink are pressuring older GEO satellite models.
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.
That plan is working in the data. Viasat had IFC systems installed and in service on about 4,580 commercial aircraft at March 31, 2026, up from about 4,120 a year earlier. It also expects about 1,000 more aircraft to enter service under existing airline deals. 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, even after cutting it from $7.2 billion a year earlier. Two important satellites, ViaSat-3 F1 and I-6 F2, suffered problems that limit the future capacity story. The market is also changing fast as low Earth orbit, or LEO, networks like Starlink win customers with lower-latency service.
So the page should not read like a victory lap. Viasat is executing better, but the price question and the balance sheet question remain. The stock needs steady aviation growth, smooth ViaSat-3 F2 and F3 service starts, and 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 4,580 commercial aircraft in service at the end of fiscal 2026.
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 about 130,000 U.S. fixed broadband subscribers at March 31, 2026.
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.
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 is down from $7.2 billion a year earlier, but it still makes cash flow important. If interest costs, satellite spending, or weak revenue eat cash, the turnaround gets harder.
LEO rivals take share
High impact · High oddsViasat now says the traditional GEO satellite industry is being disrupted by customer adoption of LEO services, including Starlink. LEO systems can offer lower latency because their satellites orbit closer to Earth. This is most dangerous in maritime, enterprise, and fixed broadband, and it may pressure pricing over time.
Satellite problems limit capacity
High impact · Medium oddsViaSat-3 F1 had a reflector deployment issue that materially hurt performance. I-6 F2 had a power subsystem anomaly and did not operate as intended. These events cap some of the capacity Viasat expected to use for future growth.
IFC backlog converts too slowly
Medium impact · Medium oddsThe bull case depends on turning the roughly 1,000 aircraft backlog into active service. Aircraft installs can slip because of airline schedules, maintenance windows, supply issues, or delays from aircraft makers. If installs slow, aviation revenue growth slows too.
Fixed broadband drag outlasts aviation growth
Medium impact · High oddsThe U.S. fixed broadband business is shrinking by design as Viasat moves bandwidth to IFC. That is a smart trade if aviation grows faster and earns better margins. 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.
