Q4 FY25 Shareholder Letter

Fellow shareholders, Our fiscal year 2025 (FY2025) was a pivotal year in creating the foundation for multi-year accelerated growth and sustained cash flow through increasing earnings and decreasing capital intensity. We are pleased with our operational performance and the accomplishments of our team towards the strategic goals we set for the year. We met or beat our guidance metrics, achieved record new contracts awards growth, made significant progress on our capital structure, integrated the first ViaSat-3 (VS-3) F1 into our global network demonstrating the expected benefits to user experience and network efficiency, completed critical milestones on our satellite roadmap, earned an inspiring reception to the new multi-orbit NexusWave maritime broadband service, introduced several network optimization innovations delivering substantial efficiency and user experience gains, reached new win-win third-party network agreements, including to reduce latency for all mobility users while also enhancing capital efficiency, and made organizational changes to further improve speed, agility, and greater structural optionality. And we enhanced financial transparency with new reporting segments and accompanying disclosures. We are also bringing major innovations to our unique and valuable spectrum rights to the MSS market segment at L-band, and the new Mobile Satellites Service capabilities they enable for our customers. Working with the MSSA, we are laying the foundation for an open architecture, standards based eco-system for Non-Terrestrial Network (NTN) extensions to the 5G and 6G networks of the future. Existing and emerging 3GPP standards foster interoperability for consumer mobile devices between terrestrial and “a single” individual satellite network. MSSA’s framework builds on these standards, enabling choice, scale, and substantially lower costs by creating an approach to NTN interoperability with, and among, all participating space networks. That approach, as adopted by the space and terrestrial eco-system participants, means mobile phones, autos, drones, and virtually any standards compliant device, can use a much more cost-effective aggregation of coordinated satellite spectrum, globally, versus depending on a single, capricious constellation. Viasat is focused on three major L-band business objectives: 1. Substantially reducing capital and operating costs for MSS/NTN open architecture and standards-based space networks. 2. Supporting, transitioning, and evolving our critical government, maritime and aeronautical safety services users to the enhanced capabilities they will need in the fully connected autonomous, unmanned, AI future by leveraging next generation space assets. 3. Transitioning our nascent global D2D NTN business from the existing NB-IoT emergency and messaging standards to the emerging 5G NR services market as new chips and devices enter and penetrate the market over the next few years. One of our very highest priorities is getting VS-3 F2 and F3 into service, and we have been updating status on our satellite roadmap. For VS-3 F2 the critical path includes corrective actions and testing the reflectors and integrating with the spacecraft. We are still planning to ship VS-3 F2 to the launch site this summer. We have adjusted the in-service date roadmap to better reflect various potential schedule uncertainties post-shipment. The VS-3 F3 schedule critical path goes through antenna subsystem integration – which uses a different manufacturer and design not requiring corrective actions. We are monitoring the launch manifest and range priorities. As previously shared, VS-3 F2 will be launched via ULA. As we achieve satellite integration and test milestones on the spacecraft, we reduce the magnitude of the “bring into service” schedule risk, but of course, that does not eliminate schedule risks extrinsic to our own spacecraft or launch campaign that could, as in the past, affect schedules by weeks or more. Our VS-3 F1 usage has been scaling steadily. Even with the antenna anomaly we have almost 2,000 planes served by VS-3 F1, tens of thousands of cumulative flights, and hundreds more each day. We commissioned a survey to compare our service on Hawaii routes, in particular, so we could benchmark user experience against LEO competition. The results are very favorable and shown on page 10 of our accompanying earnings presentation (link here). They support our view that competition is primarily about delivering measurably reliable and consistent free Wi-Fi, while providing a single interface for airlines to manage, monetize and integrate all their passenger entertainment and connectivity services. We have been a leader in innovating, delivering and measuring those services and are increasingly confident that the combination of our existing and planned fleet with our third- party partners will compete well in our target markets. Of course, we can still improve by judiciously integrating LEO networks to both further optimize latency-sensitive traffic and improve economics while meeting industry leading service quality and reliability metrics. NexusWave is already off to a good start in maritime. The terms of our Telesat Lightspeed agreement, blended with our existing and forthcoming owned and third-party fleets, and our existing and planned user terminals and network capabilities can improve user experiences and extend market access for all our mobility customers, enhance our competitive position, and reduce capital intensity. There have also been some meaningful developments regarding Ligado but it remains an ongoing legal matter. We continue to vigorously pursue our claims in Ligado’s bankruptcy and defend Ligado’s meritless lawsuit against Inmarsat. Until then, any future cash payments from Ligado have been excluded from our financial outlook and remain upside.Shareholder Letter | Q4 Fiscal Year 2025 1

We have continued to make progress on many operational, financial, and strategic fronts. We exit FY2025 stronger than when we entered as evidenced by our healthy backlog, growing operating cash flow, moderating capital expenses, and continued awards growth in key businesses. And we believe in the durability of our growth as supported by the market proof points in the accompanying earnings presentation (link here) highlighting American Airlines selecting us to scale to free Wi-Fi, along with successful free domestic trials, new global airline awards, and third-party survey data illustrating VS-3 delivering world class passenger inflight Wi-Fi experience and satisfaction on flights between Hawaii and the US. Looking ahead, we realize success in fiscal year 2026 (FY2026) is more than just hitting the numbers, it is about securing our future and accelerating growth. We have a comprehensive plan to deliver sustainable, compelling operating and free cash flow, reinforce our competitive positions, unlock portfolio value and drive returns and shareholder value. Steadfast delivery and execution are fundamental tenets in FY2026, and we believe the outcomes are enhanced confidence with the markets and attractive entry points for value capture. FY2026 is the year to reposition for growth. There will be challenges but we are playing to win. Sincerely, Mark Dankberg Shareholder Letter|Q4 Fiscal Year 2025 2

Communication Services Segment Highlights › Subsequent to quarter end, announced Amara, Viasat’s next generation, multi-orbit IFC solution for commercial aviation. Customers benefit from innovations in core satellite network design, hardware advancements, and a suite of digital products. Coupled with additional features, including smart network enhancements and application-level data linking to satellites in multiple orbits, Viasat Amara is designed with powerful scalability so airlines can differentiate a future-proof onboard passenger experience › Subsequent to quarter end, signed Telesat agreement to incorporate LEO Ka-band capacity into multi-orbit service offerings. The LEO capacity from Telesat will be seamlessly integrated with Viasat’s ultra-high throughput satellites to offer customers fast, highly reliable, robust and cost-effective connectivity services. › Launched our enhanced high performance in-flight connectivity (IFC) service with STARLUX. In total, 48 aircraft are expected to install or transition to Viasat’s most advanced IFC system, based on the ViaSat-3 compatible and multi-orbit Amara ready high-performance GM-40 terminal solution › Selected by Aeromexico to retrofit its Boeing 787 Dreamliner fleet of 17 aircraft with Viasat’s most advanced in-flight Wi-Fi solution. Additionally, Aeromexico is using the Viasat Ads platform to offer its passengers free, ad-supported, streaming capable connectivity sessions › Subsequent to quarter end, selected by Riyadh Air, Saudi Arabia’s new premium international airline to provide a “Full, Fast, Free” in-flight connectivity for all Riyadh Air loyalty members on initial Boeing 787 Dreamliner factory-installed deliveries. The service includes access to streaming subscriptions on guests’ own personal devices, which 71% of passengers report as a priority activity according to our 2024 Passenger Experience Survey. › Verified 340 Mbps NexusWave download speeds demonstrating the power of network bonding for Maritime customers under real-world conditions.

YoY growth in aviation was more than offset by declines in FS&O relating to US fixed broadband and the divestiture of the Energy Services Systems Integration business, as well as in government satcom. Q4 FY2025 total backlog of $2.6 billion decreased 16% YoY; aviation backlog increased 37% offset by FS&O due to decline of the US fixed broadband business and the removal of the Energy Systems Integration business backlog. Revenue In Q4 FY2025, Communication Services revenue decreased 4% YoY to $825 million. The decline was primarily driven by product revenues which were down 23% primarily due to accelerated IFC terminal deliveries in the prior year period and the divestiture of the Energy Services Systems Integration business in Q3 FY2025. Service revenue increases of 16% and 5% YoY from government satcom and aviation, respectively, were more than offset by a 19% YoY decrease in FS&O services and an 8% YoY decrease in maritime services as third-party companion offerings drove ARPU pressure. Commercial and business aviation ended the quarter with approximately 4,030 and 2,000 aircraft in service, respectively, growing YoY and sequentially. Maritime vessels were slightly down YoY and sequentially to about 14,000. U.S. fixed broadband ended the quarter with approximately 189,000 subscribers and $117 average revenue per user. Adjusted EBITDA Communication Services Q4 FY2025 Adjusted EBITDA of $306M increased 2% compared to prior year. Strong operating performance in government satcom services and lower Communications Services segment research and development costs were partially offset by maritime and FS&O services, and overall product revenues.

Defense and Advanced Technologies Segment Highlights Selected to lead the lunar orbiting satellite communications portion of the European Space Agency’s Moonlight Program, alongside Telespazio. People, spacecraft, and lunar vehicles will access the system to speed communications among themselves and back to earth to better enable their scientific and exploration projects including their position over the Moon. The UK Space Agency selected Viasat to lead the UK ecosystem to deliver the communications capability First-of-its-kind demonstration of direct-to-device connectivity for the automotive sector. The tests, conducted with ecosystem partners in Brazil, enabled vehicles to seamlessly switch between satellite and cellular networks, ensuring uninterrupted connectivity based on location Delivered 100,000th Type 1 encryption device supporting the government with high assurance solutions that help keep the most sensitive data secure from emerging and evolving threats. Our teams design, develop, manufacture and deliver these solutions. Viasat’s encryption solutions have earned a ubiquitous presence — protecting information from the tactical edge on the battlefield to enterprise cloud networks and data centers to satellite ground operations and space assets. Received the MSUA Satellite Mobile Innovation Award for Software Defined Network Innovation with our Multi-Domain Unified Secure Integrated Communications (MUSIC) solution. MUSIC was central to Viasat’s award from Defense Innovation Unit to support the Replicator autonomous systems program. Viasat also received the MSUA award in the Government Mobile Innovation category for our Hybrid SATCOM Approach solution. Awards Defense and Advanced Technologies Q4 FY2025 awards increased 58% YoY to $395 million. The YoY growth was primarily driven by significant awards in information security and cyber defense products, tactical networking products, advanced technologies and other, and space and mission systems. Backlog was $984 million in Q4 FY2025, an increase of 50% YoY and 6% sequentially, with a book-to-bill of 1.2. Revenue Q4 FY2025 Defense and Advanced Technologies revenue was $322 million, an 11% increase YoY. The YoY revenue growth was driven primarily by product revenue increases in tactical networking and information security and cyber defense. Adjusted EBITDA In Q4 FY2025, Defense and Advanced Technologies Adjusted EBITDA increased 19% YoY to $69 million. Strong operating performance in tactical networking more than offset higher R&D expenditures. Defense and Advanced Technologies segment provides a diverse set of resilient, vertically integrated solutions, leveraging core technical competencies in encryption, cyber security, tactical gateways, modems and waveforms, to government and commercial customers

Balance Sheet, Cash Flows and Liquidity OPERATING CASH FLOW4 Operating Cash Flow $ in millions Viasat generated $298 million in operating cash flow during the quarter, an increase of $66 million YoY and $79 million sequentially. The YoY increase primarily reflects improved operating performance and a decline in working capital largely from increases in accounts payable and other accrued liabilities. The sequential increase primarily reflects a decline in working capital largely from increases in other accrued liabilities and accounts payables and lower cash taxes. Capital Expenditure Q4 FY2025 capital expenditures declined 34% YoY to $248 million. Capital expenditures decreased YoY primarily due to lower satellite expenditures related to timing of certain space, ground infrastructure and other capex payments. Net Debt and Liquidity CAPITAL EXPENDITURE4 Viasat ended Q4 FY2025 with $2.8 billion in available liquidity which $ in millions consisted of $1.61 billion in cash and cash equivalents and $1.14 billion of borrowing ability under our two undrawn revolving credit facilities. Net debt3 decreased sequentially to NET DEBT3 $ in billions $5.6 billion primarily due an increase in cash and cash equivalents, resulting in a slight sequential decline in our net debt relative to LTM Adjusted EBITDA. Subsequent to fiscal year end, we used cash on hand to redeem early all $442.6 million remaining aggregate principal amount of our senior notes due 2025. $ Shareholder Letter|Q4 Fiscal Year 2025 7

Outlook We view FY2026 as the launch year for multi-year earnings growth, cash generation and continued evolution. We expect to multiply our global bandwidth with new satellites entering service and continue advancing our multi-orbit strategy (focusing on offsetting third-party capacity margin impact with further network optimization). We will remain actively evaluating portfolio and strategic opportunities to unlock value and deploy any potential cash proceeds to paying down debt. We will stay hyper focused on delivering a sustainable and compelling inflection to positive free cash flow while continuing to invest in future growth opportunities unique to us. We will work towards reducing the capital intensity of our portfolio by leveraging an expanding partnership ecosystem while planting seeds for emerging growth markets including evolved MSS and D2D. We will emerge as a better company, with fully competitive franchises, a derisked debt maturity profile and strengthened capital structure which we believe will enhance our market valuation. › For FY2026 we expect low single digit YoY revenue growth and flattish YoY Adjusted EBITDA. – We expect Communication Services segment FY2026 flat revenue performance to be driven by low double-digit growth in aviation services that we expect will be offset by a lower rate of declines in fixed services and other. – We expect Defense and Advanced Technologies FY2026 mid-teens YoY revenue growth to be driven primarily by strong double-digit growth in both information security and cyber defense and space and mission systems. › We continue to expect Net debt3 relative to LTM Adjusted EBITDA to increase modestly by the end of FY2026. › In FY2026, we continue to expect capital expenditures of approximately $1.3 billion (range includes approximately $450 million for Inmarsat related capital expenditures). › Reflecting expectations for another year of double-digit operating cash flow and the timing of capital expenditures, we continue to expect an inflection to positive free cash flow in the second half FY2026. We want to reiterate that we realize success in FY2026 is more than just hitting the numbers, it is about securing our future and accelerating growth. We are confident in our plan to deliver sustainable, compelling operating and free cash flow, bolster our competitive positions, unlock portfolio value and drive returns and shareholder value. FY2026 is the year to reposition for growth. There will be challenges but we are playing to win. Shareholder Letter | Q4 Fiscal Year 2025 8

Use of Non-GAAP Financial Information To supplement Viasat’s consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP), Viasat uses non-GAAP net income (loss) attributable to Viasat, Inc., Adjusted EBITDA, net debt and free cash flow, measures Viasat believes are appropriate to enhance an overall understanding of Viasat’s past financial performance and prospects for the future. We believe non-GAAP net income (loss) attributable to Viasat, Inc. and Adjusted EBITDA provide useful information to both management and investors by excluding specific expenses that we believe are not indicative of our core operating results. We believe net debt provides useful information to both management and investors in order to monitor our leverage (including our ability to service our debt and make capital expenditures) and evaluate our consolidated balance sheet. A limitation associated with using net debt is that it subtracts cash and therefore may imply there is less debt than the most comparable GAAP measure. We believe free cash flow is an important liquidity metric because it measures, during a given period, the amount of cash generated that is available to repay debt obligations, make investments, fund acquisitions and for certain other activities. Free cash flow can vary significantly from period to period depending upon, among other things, operating asset and liability balances, service and product revenues, operating efficiencies, increases or decreases in purchases of property and equipment, subscriber additions (losses), subscriber churn, and other factors. In addition, since we have historically reported non-GAAP results to the investment community, we believe the inclusion of non-GAAP numbers provides consistency in our financial reporting and facilitates comparisons to Viasat’s historical operating results. Further, these non-GAAP results are among the primary indicators that management uses as a basis for evaluating the operating performance of our segments, allocating resources to such segments, planning and forecasting in future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for measures of financial performance prepared in accordance with GAAP. A reconciliation of specific adjustments to GAAP results is provided in the tables below under “Non-GAAP Financial Reconciliation.” Copyright © 2025 Viasat, Inc. All rights reserved.
