Viasat (VSAT) Q4 2026 earnings review
Free Cash Flow Inflects Positive, But Commercial Pressures Persist
Viasat wrapped up FY26 with a 2% YoY revenue increase in Q4, driven entirely by a robust 12% surge in the Defense and Advanced Technologies (DAT) segment. However, the legacy Communication Services (CS) segment continues to act as a drag, with revenue falling 2% as the fixed broadband business rapidly bleeds subscribers. While GAAP Net Income reversed to a positive $58.8M from a massive $246.1M loss last year, this was heavily skewed by a $203M gain on the sale of the Navarino joint venture—Non-GAAP Net Income remained negative at $(3.2)M. The real bright spot is capital discipline: CapEx is steadily declining, allowing Viasat to print its fifth consecutive quarter of positive Free Cash Flow, a critical milestone for its deleveraging strategy.
🐂 Bull Case
The DAT segment achieved a record backlog of $1.2B (+23% YoY), driven by soaring demand for information security, cyber defense, and tactical networking. This provides high visibility into FY27's guided mid-teens growth.
With FY26 CapEx dropping below $1B and projected to fall further in FY27, Viasat has generated $177M in FY26 Free Cash Flow (excluding the $420M Ligado payment). It now has the organic cash generation to actively pay down its $6.7B debt load.
🐻 Bear Case
U.S. fixed broadband subscribers plummeted to 130,000, down from 189,000 a year ago. This structural decline is severely pressuring the Communication Services segment's margins.
Despite a headline return to GAAP profitability, operations remain under pressure. Adjusted EBITDA fell 1% in Q4, and positive net income was entirely dependent on a one-time $203M asset sale.
⚖️ Verdict: ⚪
Neutral. Management is executing well on the things they can control—CapEx reductions, debt paydown, and defense contract wins. However, until the bleeding stops in the fixed broadband unit, consolidated margin expansion will remain elusive.
Key Themes
Defense and Advanced Technologies (DAT) Momentum
Accelerating. DAT is currently the sole growth engine for the company. Q4 revenue jumped 12% YoY to $361M, and Adjusted EBITDA grew 20% to $83M. Growth is primarily fueled by a large upgrade cycle for quantum-resistant encryption products and space/mission systems. The book-to-bill ratio remains highly favorable at 1.1x.
Fixed Broadband Subscriber Collapse
Decelerating aggressively. The U.S. fixed broadband business continues to deteriorate rapidly as alternative connectivity options (like LEO constellations) take market share. Subscribers dropped from 189,000 in 25Q4 to just 130,000 in 26Q4. Consequently, Fixed Services & Other (FS&O) revenue fell 24% YoY in the quarter. This extreme drag is offsetting the double-digit growth seen in the Aviation unit.
Aviation Connectivity Scales Up
Stable. The commercial aviation unit remains a reliable growth vector. Aircraft in service increased 10% YoY to 4,450, pushing aviation service revenues up 11% YoY. The shift toward 'Full, Fast, Free' Wi-Fi models with carriers like American Airlines and Southwest is driving sustained capacity demand.
Low Quality of GAAP Earnings
Reversing (from negative to positive), but artificially so. Viasat reported GAAP Net Income of $58.8M for Q4, a massive optical improvement from the $246.1M loss a year ago. However, the data directly contradicts the narrative of an operational profitability turnaround. Non-GAAP Net Income was actually $(3.2)M. The GAAP positive result was driven almost entirely by the $203M proceeds from selling its equity investment in Navarino and deferred interest income from the Ligado settlement.
Communication Services Margin Compression
Decelerating. Despite aviation growth, the Communication Services segment saw Adjusted EBITDA decline 6% YoY to $287M. Management attributed this to the rapid drop in high-margin fixed services revenue, combined with increased R&D spending required to support the company's multi-orbit initiatives. Margin recovery here is entirely dependent on successfully deploying ViaSat-3 capacity.
Equatys JV and Direct-to-Device (D2D) Infrastructure
Viasat is heavily promoting its intent to form 'Equatys' with Space42. This joint venture is designed to provide shared, multi-tenant L- and S-band infrastructure for non-terrestrial network (NTN) D2D services. By acting as the 'technology prime contractor' and operating an open, 3GPP-standard network, Viasat aims to drastically lower capital intensity compared to closed, proprietary LEO constellations.
Macro Headwinds: U.S. Government Shutdown Impacts
Management explicitly noted that FY26 financial results were achieved 'despite headwinds from the U.S. Government shutdown during the back half of the fiscal year.' While the DAT segment still posted strong numbers, this highlights the vulnerability of contract timing and program awards to federal budget dysfunction.
Other KPIs
Stable. Generated $24M in Q4, marking the fifth consecutive quarter of positive Free Cash Flow. For the full year, FCF was $177M (excluding the one-time $420M Ligado lump sum). This is a monumental $299M operational improvement year-over-year from FY25's $(122)M cash burn, proving the business model can be self-funding post-Inmarsat integration.
Accelerating. Backlog grew 15% YoY, led by a 23% jump in the Defense segment. Communication Services backlog also grew a healthy 11% YoY ($2.9B), suggesting that multi-orbit mobility demand is offsetting the structural decay in the legacy fixed broadband business.
Improving. Net debt declined sequentially from $5.1B in Q3 to $4.8B in Q4, aided by the Navarino sale, the Ligado settlement, and positive operational FCF. Management noted 'very substantial progress' toward its stated goal of bringing the leverage ratio below 3.0x.
Guidance
Accelerating. Compared to FY26's 3% YoY growth, management expects a slight acceleration. This will be anchored by mid-teens growth in the Defense segment, which will outpace the slower low-single-digit growth expected in Communication Services.
Stable. Compares to $1.55B in FY26. Management explicitly stated that growth will be heavily weighted toward the second half of FY27, implying potential margin pressure in the coming H1 as they continue to invest in R&D and absorb fixed broadband subscriber losses.
Decelerating. A slight reduction from FY26's $993M, indicating that the heaviest capital intensity phase (Inmarsat integration and ViaSat-3 construction) is firmly in the rearview mirror. Includes ~$325M for Inmarsat-related CapEx.
Stable. Essentially flat compared to FY26's $177M (excluding the Ligado payment). While Operating Cash Flow is guided to be flat YoY, the slight reduction in CapEx ensures the company remains in positive cash-generation territory, protecting its deleveraging mandate.
Key Questions
Fixed Broadband Stabilization
U.S. Fixed Broadband subscribers fell from 189k to 130k this year. At what subscriber level or revenue threshold do you see this business finally finding a floor, and are there plans to harvest it rather than reinvest?
Equatys Capital Sizing
Regarding the Equatys D2D joint venture with Space42, how much upfront capital contribution is Viasat expected to provide over the next 12-24 months, and is any of this currently baked into the $950M-$1B FY27 CapEx guide?
