ViasatTM Q3 FY23 SHAREHOLDER LETTER

Fellow Shareholders, We are happy to report that after a long, painstaking process the first ViaSat-3 satellite has completed construction and testing, and is scheduled for launch the week of April 8th. With the approach of this first launch it’s worth reviewing why we decided to invest in the ViaSat-3 constellation and the opportunities it enables. Our success in satellite broadband builds on three simple points: 1) broadband customers value speed and bandwidth, 2) space systems are capital intensive so efficiently matching bandwidth supply from space to geographic and temporal demand on the ground (and in the air) drives economic success, and 3) global mobility markets are difficult or impossible to serve terrestrially and are among the most valuable – and technically challenging – to serve efficiently. With ViaSat-1 and ViaSat-2 we were able to test these value propositions in real, highly competitive regional markets in and around North America. They’ve worked well and we are confident they will continue to do so. With each satellite network we introduced space and ground innovations focused on speed, bandwidth, and the ability to more efficiently match bandwidth supply and demand. The supply/demand matching problem is especially critical in mobility where aircrafts and ships converge at transportation hubs. Our success in North American In-Flight Connectivity (IFC) supports our thesis – demonstrated by our airline customers’ ability to offer free Wi-Fi to all of their passengers, including at congested hub airports, at scale. The ViaSat-3 system is intended to enable a substantial leap in space and ground technology—designed to deliver far more bandwidth per unit of capital, over very large coverage areas, with dynamic control over when and where that bandwidth is delivered. And, by building three satellites concurrently we can extend these capabilities and economic advantages to global mobility markets, not just regionally. We are confident our success in the North American IFC market can be extended globally, and that our initial forays into Australia, Brazil, Europe and, more recently, China are indicative of that. When we decided to undertake the ViaSat-3 program we understood there were cost and schedule risks. Existing technology, or fewer than three satellites, could not unlock the opportunities in global mobility. We’ve faced technical, manufacturing and unprecedented pandemic challenges along the way, as did our spacecraft manufacturer. Recently, launch scheduling also added somewhat to the delay. With the Americas satellite complete, we believe the ViaSat-3 specific issues for the EMEA and APAC satellites are largely behind us. We believe the technology is state-of-the-art, benefits from powerful technology trends in cloud computing, AI, and cyber security and creates a foundation for more performance gains. Tests of the space and ground technologies support that. The costs and schedules for the EMEA and APAC satellites are significantly improved relative to the Americas first flight, as we and our spacecraft manufacturer refined construction and test methods, and pandemic effects diminished. The delay in the first satellite meant our bandwidth supply in the U.S. could not keep pace with our very rapid IFC growth. We decided to continue to grow IFC by re-allocating bandwidth from residential to IFC. The upcoming launch of ViaSat-3 Americas offers abundant fuel for renewed residential growth. It enables more attractive service plans and/or pricing and the ability to focus more bandwidth on the highest demand areas. There are still an estimated 10 to 15 million U.S. homes that are candidates for high speed, high bandwidth satellite services. U.S. residential earnings are attractive and we believe we can reignite solid growth there again. We are disappointed with the delay, but positioned for growth: Immediately subsequent to quarter-end, we concluded the sale of our Link-16 Tactical Data Links business for $1.96 billion (Link-16 TDL Sale), which yielded gains of over $1.5 billion and about $1.8 billion in cash, net of taxes. While it reduces our continuing operations revenue and earnings outlook, we believe we are positioned to achieve our ongoing growth objectives via a greater focus on the satellite services opportunities enabled by ViaSat-3. The gain in FY2023 will make this year, by far, the most profitable in our history and the related cash proceeds strengthens our balance sheet and fuels the success-based capital investments associated with growth. Our IFC business is seeing very robust growth – not only in aircraft in service, follow-on orders from existing customers, and wins with new airlines – but also in engagement among passengers as airlines leverage our performance and scale, especially in North America. Other nascent mobility markets (e.g. business aviation and maritime) are seeing attractive growth on relatively small bases enabled by current satellites. The regulatory decision processes for the Inmarsat transaction are nearing completion. We believe the transaction can accelerate our evolution to primarily serving global mobility customers. The respective space systems are highly complementary, given our historic focus on regional service and Inmarsat’s legacy mission of global coverage. We believe the combined company will benefit customers by delivering more service options sooner, and greater operational and capital synergies. Also, the underlying technology in ViaSat-3 could transform Inmarsat’s L-band services, including in the emerging direct-to-device market. Viasat enters calendar 2023 at a milestone moment for the company’s next phase of growth. With deployment of two of our ViaSat-3 satellites planned for the first half of fiscal year 2024, and with the recent completion of the Link-16 TDL Sale, Viasat is moving deliberately towards its future as a global communications services company, delivering high-volume, affordable bandwidth across mobility, consumer, enterprise and government applications. We are excited and energized by the opportunities, the very large and diverse addressable markets, the huge amounts of bandwidth we’ll have available, and the revenue, earnings, and free cash flow prospects created.

Q3 FY2023 Financial Results Subsequent to quarter end, on January 3, 2023, Viasat completed the Link-16 TDL Sale for $1.96 billion. Net cash proceeds are expected to be approximately $1.8 billion after taxes, fees, and other expenses. The gain on the sale is expected to be the dominant factor in FY2023 full year profitability Revenue1 for Q3 FY2023 was slightly down YoY to $714 million while revenue from continuing operations increased 4% YoY to $651 million Net loss2 of $42 million for Q3 FY2023 increased by $36 million compared to Q3 FY2022 primarily due to lower Adjusted EBITDA and higher income tax and interest expense Adjusted EBITDA3 for the quarter declined 15% YoY to $139 million. Adjusted EBITDA from continuing operations declined 3% YoY to $122 million primarily due to lower revenue from fixed broadband, network costs associated with the upcoming ViaSat-3 launch, and outsized continuing operations cost base under active management, partially offset by continued growth in commercial air IFC service Commercial Networks revenue increased 20% YoY and 35% sequentially - excluding the impact of the Acacia litigation payment in Q2 FY2023 - driven primarily by increased commercial air IFC terminal shipments Government Systems revenue from continuing operations grew 3% YoY driven by 10% YoY growth from service revenue despite ongoing certification delays and supply chain issues Satellite Services revenue was slightly down YoY, with fewer residential subscribers in the U.S. partially offset by higher fixed broadband ARPU, higher IFC revenue from 17% more aircraft in service compared to Q3 FY2022, and organic growth in LATAM international fixed broadband Awards4 for the quarter increased 8% YoY to $617 million, while awards from continuing operations increased 14% YoY driven primarily by strong bookings in Commercial Networks for commercial air IFC terminal shipments and antenna systems products Net leverage5 increased sequentially to 4.7x LTM Adjusted EBITDA, with higher net debt and lower Adjusted EBITDA. Pro forma for the Link-16 TDL Sale, net leverage would have been approximately 2.0x LTM Adjusted EBITDA AWARDS4 $ in millions $569 Q3 FY22 $617 Q3 FY23 $1,996 Q3 FY22 YTD $2,514 Q3 FY23 YTD REVENUE1 $ in millions Discontinued Ops Continuing Ops $720 Q3 FY22 $714 Q3 FY23 $2,086 Q3 FY22 YTD $2,137 Q3 FY23 YTD OPERATING INCOME (LOSS)6 $ in millions $4.5 Q3 FY22 ($17.5) Q3 FY23 $29.1 Q3 FY22 YTD ($17.6) Q3 FY23 YTD NET INCOME (LOSS)2 $ in millions ($6.6) Q3 FY22 ($42.2) Q3 FY23 $13.6 Q3 FY22 YTD ($112.0) Q3 FY23 YTD NON-GAAP NET INCOME (LOSS)2 $ in millions $24.7 Q3 FY22 ($10.9) Q3 FY23 $83.4 Q3 FY22 YTD ($13.9) Q3 FY23 YTD ADJ.

The decrease YoY was driven primarily by tactical data links products (which is part of our Link-16 TDL business that was held for sale during the period) and network management services partially offset by awards growth from government mobile broadband services and tactical satcom radio products. Government Systems ended the quarter with backlog of $1.1 billion. Awards and backlog7 from continuing operations in Government Systems were $122 million and $530 million, respectively. Revenue Q3 FY2023 Government Systems revenue was $244 million, a decrease of 10% YoY. Product revenues declined 18% YoY primarily from lower tactical data links product deliveries partially offset by 12% YoY services revenue growth mostly due to tactical satcom networks. Revenue from continuing operations was $182 million, an increase of 3% compared to the prior year period. Certification delays constrained growth during the third quarter, however, subsequent to quarter-end progress was made in mitigating this bottleneck. Adjusted EBITDA Government Systems Q3 FY2023 Adjusted EBITDA was $68 million, a decrease of 16% YoY driven predominantly by the lower flow through of product revenue from tactical data links. Adjusted EBITDA from continuing operations grew 15% YoY to $51 million compared to Q3 FY2022. The YoY continuing operations increase resulted primarily from higher gross margins from services businesses, which offset higher R&D expenses. Shareholder Letter | Q3 Fiscal Year 2023 3

The partnership aims to expand access to connectivity in the Democratic Republic of the Congo, Nigeria, Guatemala, Mexico and the United States › Received Better Satellite World Award from Space & Satellite Professionals International for helping Ukrainian refugees in Slovakia access the internet through satellite connectivity Revenue Q3 FY2023 Satellite Services revenue was $302 million, a 2% decrease YoY and a 1% increase sequentially. Strong commercial air IFC service growth was offset by a decline in U.S. fixed broadband subscribers. We expect continued declines in U.S. fixed broadband subscribers until we begin to scale commercial service on ViaSat-3 Americas in early summer of calendar 2023. Adjusted EBITDA Satellite Services Q3 FY2023 Adjusted EBITDA was $90 million, a 19% decrease YoY and a 1% decrease sequentially. The Adjusted EBITDA decline was primarily due to ground network activation expenses associated with the upcoming ViaSat-3 launches, declines in the U.S. fixed broadband subscriber base, lower gross margins from energy services and international expansion costs, offset by strong commercial air IFC services growth. 1,880 1,910 1,930 1,970 2,140 Aircraft Installed 1,800 1,830 1,900 1,950 2,110 Aircraft In-Service Q3 Q4 Q1 Q2 Q3 FY22 FY22 FY23 FY23 FY23 Commercial Aircraft Shareholder Letter | Q3 Fiscal Year 2023

Launch is anticipated for the week of April 8th in Cape Canaveral Selected by Sichuan Airlines and AeroSat Link, a subsidiary of China Satcom, to provide IFC technology and equipment for installation on its Airbus A320 family of aircraft Awards In Q3 FY2023, Commercial Networks awards increased 62% compared to Q3 FY2022 driven by strong orders from commercial air IFC terminals, antenna systems programs and energy products. AWARDS, REVENUE AND ADJ. EBITDA3 $ in millions $267 $527 $393 $460 $82 $26 Awards Revenue Adj. EBITDA Q3 FY22 YTD Q3 FY23 YTD Revenue Q3 FY2023 Commercial Networks revenue was $167 million, an increase of 20% YoY. Third quarter deliveries grew as anticipated with commercial air products delivering over 240 IFC terminals, a significant increase over the prior year period and the previous quarter. Growth from energy products and satellite products also contributed to the YoY increase. Adjusted EBITDA Commercial Networks Q3 FY2023 Adjusted EBITDA was a loss of $19 million, an improvement of 33% YoY. Increased revenue flow through from commercial air IFC terminals and energy products combined with a significant reduction of R&D expenditures for satellite payload and ground network development were the main contributors for the YoY improvement. ViaSat-3 Update The ViaSat-3 EMEA satellite is undergoing spacecraft integration at Boeing and the ViaSat-3 APAC satellite is nearing completion of final payload integration and testing at our Tempe, Arizona facility.

Balance Sheet, Cash Flows and Liquidity OPERATING CASH FLOW $ in millions $159 Q3 FY22 $119 Q4 FY22 $40 Q1 FY23 $188 Q2 FY23 $89 Q3 FY23 CAPITAL EXPENDITURE & INVESTMENT $ in millions $237 Q3 FY22 $279 Q4 FY22 $271 Q1 FY23 $284 Q2 FY23 $296 Q3 FY23 NET DEBT & NET LEVERAGE RATIO5 $ in millions (except net leverage) 3.2x $2,031 $2,214 Q3 FY22 3.6x Q4 FY22 4.2x $2,443 $2,571 Q1 FY23 4.2x Q2 FY23 4.7x $2,791 Q3 FY23 Operating Cash Flow Viasat generated $89 million in operating cash flow during the quarter, a decrease of 44% YoY and 53% sequentially. The YoY comparison reflects the decrease in operating results and increased working capital tied to accounts receivable and IFC product inventory concurrent with revenue growth and higher terminal deliveries for that business. Capital Expenditure & Investment Q3 FY2023 capital expenditures were $296 million, an increase of 25% YoY. The increase was primarily due to higher expenditures in capitalized software development and other related infrastructure and to a lesser extent increased satellite capital expenditures for the ViaSat-3 constellation program. Debt and Leverage Net debt increased $220 million sequentially to $2.8 billion at the end of Q3 FY2023 while net leverage increased to 4.7x LTM Adjusted EBITDA. During the quarter, our liquidity declined to $339 million, which included $182 million in cash and cash equivalents and $157 million of remaining borrowing capacity under our revolving credit facility. With the closing of the Link-16 TDL Sale immediately following quarter end, we significantly increased liquidity and applied a portion of the net proceeds of the sale to reduce debt. Our pro forma net leverage after giving effect to the Link-16 TDL sale would have been approximately 2.0x LTM Adjusted EBITDA at the end of Q3 FY2023 and pro forma liquidity would have been approximately $2.3 billion. Shareholder Letter | Q3 Fiscal Year 2023 6

Outlook During Q3 FY2023, consolidated financial performance was adversely impacted by weakness in our Link-16 TDL business while our continuing operations benefitted from Government Systems’ tactical satcom networks business and seasonally lower R&D expense. For the full year FY2023, we expect Adjusted EBITDA from continuing operations to be roughly flat YoY, with fourth quarter bearing increased ViaSat-3 ground network operating expenses in preparation for ViaSat-3 Americas service launch and some IFC terminal deliveries shifting to the right due to delays in new aircraft deliveries to our airline customers. This excludes the significant gain from the Link-16 TDL Sale, and the related stranded cost remediation charges expected in Q4 FY2023. Full year FY2023 earnings will be very strong, dominated by the Link-16 TDL Sale. Fiscal year 2024 will be an exciting year for us as we begin to deploy and scale our ViaSat-3 constellation, including the first two satellite launches. While growth timing reflects the delays incurred in launching ViaSat-3, the opportunities are very attractive. For the full year FY2024, we expect Adjusted EBITDA from continuing operations to grow double digits YoY. Cash flow from operations is expected to improve YoY driven by Adjusted EBITDA growth and a reduction in working capital. Despite the launches of both ViaSat-3 Americas and ViaSat-3 EMEA, we believe capital expenditures will remain flat compared to FY2023 with a larger portion of our investments moving to success-based expenditures as we seed a resurgence in growth for our fixed broadband business. This brings FY2024 net leverage targets to around 4.0x as we transition to our fully deployed network in FY2025. We expect Q1 FY2024 to be impacted by ViaSat-3 launch related costs, increased advertising and ground network expenses, seasonality in IFC services and weakness in U.S. fixed broadband in advance of ViaSat-3 Americas. The quarterly profile of revenue and Adjusted EBITDA is expected to improve throughout the year as we scale our commercial service on ViaSat-3 Americas in early summer with incremental margins improving in later quarters. Longer term – on a stand-alone basis and pro forma for the Link-16 TDL Sale – we expect to achieve much faster growth in FY2025, as we scale into our ViaSat-3 satellites following their launch. We continue to believe that we will achieve our stand-alone FY2025 target of doubling revenue and more than doubling Adjusted EBITDA relative to FY2020 – again, pro forma for the Link-16 TDL Sale. We remain committed to delivering positive free cash flow shortly after ViaSat-3 EMEA enters commercial service. Considering the cash flow effects of the Link-16 TDL Sale, the current ViaSat-3 launch schedules, and quarterly seasonality and boundary effects, we anticipate achieving positive free cash flow in the spring of calendar 2025, approximately two quarters later than our prior guidance. Sincerely, Mark Dankberg Shareholder Letter | Q3 Fiscal Year 2023 7

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. and Adjusted EBITDA, measures Viasat believes are appropriate to enhance an overall understanding of Viasat’s past financial performance and prospects for the future. We believe the non-GAAP results provide useful information to both management and investors by excluding specific expenses that we believe are not indicative of our core operating results. 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.
