Exhibit 99.2

Viasat Q4 FY26 Shareholder Letter Fellow Shareholders, Our fiscal year 2026 financial results are largely consistent with our expectations and plans entering the year despite headwinds from the U.S. Government shutdown during the back half of the fiscal year. We are pleased with our operational and financial performance, as well as the accomplishments of our teams as we compete and win in attractive growth markets. Highlights for the year include: • Record new contract awards and backlog, along with modest growth in revenue, and Adjusted EBITDA2, both of which were also at record levels. • Cash generation of nearly $600 million in free cash flow4, and approximately $180 million excluding the Ligado lump sum payment. We delivered positive free cash flow in each of the last five quarters. We achieved this while still continuing to invest in our future. • Strengthening our capital structure – including very substantial progress toward our net debt3 relative to LTM Adjusted EBITDA ratio stated goal of below 3x. We have also made important progress with ViaSat-3 (VS-3). Subsequent to quarter end, we successfully completed all deployments on VS-3 F2 including the reflectors and boom, and VS-3 F3 launched successfully on April 29th. Since then, radiator and solar array deployments have been successfully completed and orbit raising is underway. VS-3 F3, planned to cover the Asia-Pacific region, is expected to arrive on station in approximately one month, with service entry anticipated in August or September calendar year 2026. Our ongoing fleet expansions support key growth initiatives in aviation, maritime, fixed services, and government satcom businesses. They also introduce important new capabilities, including new forms of resilience for our government and commercial customers. We believe that the VS-3 satellites are the most advanced commercial satellites in the world in terms of adaptive beamforming for cost efficiencies, user performance improvements, and resilience to interference. We also believe they set new commercial standards for solar power generation and thermal dissipation – with both of those capabilities among the foundational technology challenges for developing economical data centers in space. Looking ahead, we have three key near-term focus areas to drive growth in fiscal year 2027 and beyond. 1. Our ongoing fleet expansion is expected to roughly triple bandwidth inventory – and increasing adaptive beamforming flexibility provides an additional boost to the fleet’s effective capacity, offering higher speeds on both forward and return links. We will also expand our fleet-wide multi-orbit capabilities in maritime by augmenting our existing LEO and GEO resources. We are making steady progress on our Aera Ka-band multi-orbit terminal for IFC, which has already entered the Line-Fit certification process for all Boeing commercial airliners. Telesat is also progressing with the launch of its first pathfinder Lightspeed LEO satellites, scheduled this year, with initial global service planned for late next year. While the market for broadband satellite services is very competitive, it is also growing rapidly, and we believe we have a good opportunity to grow with it. 2. Developing and deploying multi-tenant, multi-orbit L- and S-band shared infrastructure delivering next-generation Mobile Satellite Services, including for global aero and maritime safety, as well as next-generation air, ground, and maritime vehicle autonomy, along with mobile D2D opportunities – with a focus on lowering capital intensity. While we are aiming for services in calendar year 2029, we are targeting significant revenue from our role as the technology provider for Equatys, the space infrastructure entity we are forming along with Space42. 3. We also intend to sustain the rapid growth rate in our Defense and Advanced Technologies (DAT) segment for both defense and commercial markets, building on our dual-use advanced technology. The DAT segment is the first place where new technology developments, like Equatys, will be recognized. The Equatys initiative for next-generation L- and S-band space and ground infrastructure is anticipated to be an important contributor for broadband services, mobile L- and S-band services, and DAT. We continue to work closely with Space42 and other potential partners as co-founders of the new, shared infrastructure entity that is intended to substantially improve capital productivity for L- and S-band satellite mobility services. The Equatys infrastructure is intended to enable 3GPP standards for interoperable NTN services through both satellite-specific and terrestrial frequencies. The shared-tower infrastructure model can enable greater spectrum efficiency as well as reduced infrastructure costs for all participating parties. As with terrestrial shared tower infrastructure, the spectrum rights and obligations remain with the participating licensees, initially Viasat and Space42 - but with the potential to expand to include additional partners. Viasat is expected to participate as the initial technology prime contractor for Equatys. Space-based L- and S-band beamforming technology is at the heart of the NTN D2D opportunity, and our technology solution both benefits from, and advances, our long history of advanced L-band and Ka- band broadband space-based phased array technology. The foundational Equatys satellite and phased array technology is also designed to support multi-orbit broadband (such as Ka-band) services at both GEO and LEO. The near-term market for commercial and government broadband satellite services remains both highly competitive and rapidly growing. Viasat has recently seen double-digit revenue and earnings growth in aviation, offset by declines in fixed residential services and maritime. In fiscal year 2027, we anticipate that financial results in fixed and residential services will improve, but increased competition will reduce our growth rate in aviation services. However, we are seeing accelerating growth opportunities in our DAT segment that, in combination with our Communication Services segment, create opportunities for accelerating company-wide revenue growth ahead. Shareholder Letter | Q4 Fiscal Year 2026 1 The space sector is poised to benefit from a number of exciting new defense, commercial and scientific initiatives, and we believe Viasat is well positioned to participate in a number of those.

We believe our relatively unique position as both a leading space technology innovator and leading satellite services company helps differentiate us from competitors that are, in most cases, not vertically integrated across those markets. In the near-term many of those opportunities will first be captured in our DAT segment. I would like to point out a few opportunities that generally involve innovations in business models as well as technology. One key opportunity was just announced last week, when, subsequent to the end of Q4, we received a follow-on award to our initial phase of the PTS-G (Protected Tactical Satellite – Global) contract for a first delivery of a small, low cost, maneuverable dual-band GSO U.S. government tactical satellite. We believe PTS-G is an excellent opportunity to grow our participation in government tactical space system technologies and services, and an opportunity to use technology innovation to substantially increase the effectiveness and resilience of U.S. tactical broadband satellite communications while helping address potential threats to other orbits and systems. PTS-G is closely related to the existing WGS (Wideband Global System) U.S. tactical satellite network through which the U.S. has a significant range of international partnerships and coalition interoperability relationships – so there is also a meaningful international opportunity. There are also substantial follow-on opportunities in related dual-use broadband space technology and services. Our low cost L- and S-band multi-orbit proliferated LEO and low-cost broadband maneuverable GEO satellites share important technology foundations and are evidence of the value of our vertical integration, dual-use, multi-orbit, multi-band assets, resources, and capabilities. We believe this is a key differentiator for us to provide resilient and highly valuable services to our government and commercial customers across bands and orbits. Recently the three major U.S. mobile carriers announced plans to create a joint venture (the U.S. MNO JV) around D2D NTN services. As a reminder there are D2D opportunities using both licensed satellite spectrum and supplemental satellite use of terrestrial spectrum, each offering distinct use cases: • Terrestrial spectrum via space towers can extend coverage into places where no terrestrial coverage exists. • Satellite spectrum via space towers for overlays to perfect service gaps in places where there is already coverage through terrestrial towers and access points. The Equatys business model supports a full-service approach in which Viasat can compete to deliver standard interoperable D2D NTN services using licensed satellite L-band spectrum. Alternatively, the U.S. MNO JV, or the individual Mobile Network Operator (MNO) carriers, can simply contract for shared space tower infrastructure to support the MNO’s already-owned terrestrial spectrum in locations where that is appropriate. Think of Equatys as a unique player offering “un-bundled” space infrastructure, ground infrastructure, and/or shared network operations, as well as being platform for satellite operators, such as Viasat or Space42, or other global or regional operators to offer D2D services using their licensed spectrum. The U.S. MNO JV for D2D NTN is an example of an application that we see as a good growth opportunity for Viasat as both a service provider and the initial Equatys technology provider, supporting MNOs in applying satellite capabilities to augment their terrestrial networks. Another area driving innovation and growth in satellite technology is the potential for space data centers. While launch is certainly a key enabling technology, there are several other areas that overlap key enabling satellite communications technologies, such as: • Solar power generation • Thermal dissipation • Radiation hardening or tolerance for advanced digital computing • Space-ground and space-space broadband communications including both RF and optical • Orchestration and coordination of congested orbital spectrum and spatial resources We believe we have state-of-the-art expertise and technology in a number of these areas and have numerous avenues available for research and partnerships. It is on our target list of DAT segment growth opportunities, taking advantage of our multi-orbit, dual-use, vertically integrated technology base. We have several of these significant DAT segment opportunities pending and will update our fiscal year 2027 outlook as those opportunities mature over the first half of this fiscal year. We are highly focused on a critical few strategic initiatives to ensure we can participate in rapidly evolving markets, technologies and business models while maintaining top-tier competitive positions. We have optionality in our longer-term plans, building on reduced capital intensity and improving return on invested capital with key levers available to realize shareholder value. Sincerely, Mark Dankberg Shareholder Letter | Q4 Fiscal Year 2026 2 FY 2026 Year in Review Financial Highlights Achieved record awards of $4.9 billion, driven primarily by an 8% yearover- year (YoY) increase in the Communication Services segment.

We ended the year with a record backlog of $4.1 billion, representing a 15% increase over the prior year. The Defense and Advanced Technologies segment achieved a record backlog, growing 23% YoY, while the Communication Services segment backlog grew 11% YoY. Net loss1 of $34 million improved YoY from a net loss1 of $575 million. This improvement reflects the gain on the sale of our equity investment in Navarino, higher interest income recognized on the deferral of Ligado’s quarterly fees (received as part of the lump sum payment), and higher impairment charges and loss on extinguishment of debt related to refinancing activity in the prior year. Delivered record revenue of $4.6 billion and record Adjusted EBITDA2 of $1.6 billion. > Generated $1.2 billion of operating cash flow, excluding the $420 million Ligado lump sum payment. Capital expenditures were $993 million. Free cash flow4 generated was $177 million, an improvement of $299 million YoY. As of fiscal year end 2026, we have generated positive free cash flow for five consecutive quarters. > Redeemed early with cash all remaining $442.6 million aggregate principal amount of our senior notes due 2025 and repaid the remaining $300 million in principal amount of the original Inmarsat term loan facility that was scheduled to mature in 2026. > Net debt3 relative to LTM Adjusted EBITDA declined compared to the prior year, and we ended the year with available liquidity of $2.9 billion. Business Highlights > Successfully launched ViaSat-3 (VS-3) F2 and, subsequent to quarter end, completed all deployments including the reflectors and boom. > Subsequent to quarter end, successfully launched VS-3 F3, with coverage slated for the Asia-Pacific Region. Service entry expected in August or September this calendar year. > Achieved record awards of $580 million in information security and cyber defense driven by encryption products and next generation programs wins. > Achieved record awards of over $1 billion in government satcom driven by a multi-year $234 million Southern Positioning Augmentation Network (SouthPAN) award. > Expanded satellite coverage over the Arctic region using our GX10A and GX10B Highly Elliptical Orbit (HEO) satellite payloads enabling polar coverage for government, maritime, and aviation customers. > Continued to build core mobility franchises.

The YoY increase was driven primarily by lower cash tax payments, partially offset by the timing of interest payments. The sequential increase was mainly due to a decline in working capital, reflecting a decrease in accounts receivable, partially offset by the timing of interest payments. Capital Expenditures Capital expenditures for Q4 FY2026 increased 20% YoY to $298 million, primarily reflecting higher satellite expenditures related to the timing of certain space, ground infrastructure, and other capital expenditure payments. Free Cash Flow4, Net Debt3 and Liquidity During the quarter, Viasat generated $24 million in free cash flow, a decline of $27 million compared to the prior year quarter. This decrease primarily reflects a YoY increase in capital expenditures, partially offset by higher operating cash flow. For fiscal year 2026, Viasat generated $177 million in free cash flow, excluding the $420 million proceeds from the Ligado lump sum payment. Viasat ended Q4 FY2026 with $2.9 billion in available liquidity, consisting of $1.75 billion in cash and cash equivalents and $1.15 billion of borrowing capacity under our two undrawn revolving credit facilities. During the quarter, we entered into a credit agreement with the Export-Import Bank of the United States (Ex-Im Bank) for a $189 million direct loan facility with net proceeds of $176 million, which were fully drawn following satisfaction of the conditions of utilization. In addition, we completed the sale of our equity investment in Navarino with gross proceeds of $203 million. Net debt declined sequentially to $4.8 billion, resulting in an improvement of our net debt relative to LTM Adjusted EBITDA, both sequentially and compared to the prior year period.

Shareholder Letter | Q4 Fiscal Year 2026 7 Outlook Our performance over fiscal year 2026 illustrates our continued ability to translate strategy into attractive financial results, with cash flow and net debt relative to LTM Adjusted EBITDA improvements as key indicators, and to balance near-term execution with long-term strategic positioning. We are proud of the resilience and commitment of our team to meet the challenges associated with cutting edge space technology. We made significant progress in fiscal year 2026 and are exiting the year stronger than we entered as evidenced by our record backlog, ongoing multi-orbit fleet expansion, and accelerating growth opportunities in our Defense and Advanced Technologies segment. • Revenue and Adjusted EBITDA: We expect mid-single-digit YoY revenue growth in FY2027 and Adjusted EBITDA to be flat to up slightly YoY, with stronger growth in second half of the fiscal year. o Communication Services Segment: We expect FY2027 segment revenue growth in the low single-digits YoY, driven by continued growth in aviation services, offset by a lower rate of decline in FS&O. o Defense and Advanced Technologies Segment: We expect FY2027 segment revenue growth in the mid-teens YoY, driven primarily by strong growth in information security and cyber defense, as well as space and mission systems and tactical networking. • Net Debt: We expect net debt relative to LTM Adjusted EBITDA to decrease slightly by the end of FY2027. • Capital Expenditures: We expect FY2027 capital expenditures of between $950 million and $1.0 billion, including approximately $325 million for Inmarsat related capital expenditures. • Operating and Free Cash Flow: For FY2027, we expect operating cash flow to be flat YoY and free cash flow generated to be approximately $180 million. Our free cash flow guidance excludes the benefit of the Ligado lump sum payments in both periods, as they are non-recurring. We are highly focused on a critical few strategic initiatives to ensure we can participate in rapidly evolving markets, technologies and business models while maintaining top-tier competitive positions. We are accelerating growth while investing prudently for our future and have line of sight to significant upside catalysts. We have optionality in our longer-term plans, building on reduced capital intensity and improving return on invested capital, with key levers available to realize shareholder value.

Shareholder Letter | Q4 Fiscal Year 2026 11 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 © 2026 Viasat, Inc. All rights reserved.
