Exhibit 99.2

Q3 FY24 SHAREHOLDER LETTER

Fellow Shareholders, Our Q3 Fiscal Year 2024 results reflect continued year-over-year revenue and Adjusted EBITDA1 growth driven by our mobility and government businesses. We also continued to make meaningful progress in the near-term business priorities we highlighted last quarter while strengthening our capital structure and investing for profitable growth: 1.Building operational momentum and financial performance of core businesses. For Q3 FY2024, net loss2 increased to $124 million, revenue grew 8% and Adjusted EBITDA grew 11% YoY (is inclusive of Inmarsat’s results in the prior year period) – through focused execution and positive operating leverage in our portfolio of diverse businesses across attractive markets. 2.Executing on synergy and strategic opportunities through methodical Inmarsat integration. During the quarter we completed an important milestone by integrating and organizing the company to facilitate greater efficiency using common infrastructure, operational, go-to-market, and engineering resources for delivering our services. We expect this to result in approximately $100 million in annualized cash operating savings by the beginning of FY2025. This exceeds the original $80 million run-rate target we set when the Inmarsat acquisition was announced and advances those savings by approximately two years. 3.Accelerate mobility business growth while advancing inflection to positive free cash flow. Our existing satellite fleet and the 7 Ka-band satellites under construction are key elements of our technology roadmap to achieve our multi-year growth objectives and improving productivity. Our revised capital budgets reflect the synergies enabled by our integrated space and ground infrastructure, the revenue synergy potential in our integrated portfolio, and a sharp focus on positive free cash flow. We reiterate our goal of achieving sustainable positive free cash flow in the first half of calendar 2025. For Q3 FY2024, we earned revenue of $1.1 billion, a 73% YoY increase compared to revenue from continuing operations of $651 million in Q3 FY2023, reflecting the impact of the acquisition of Inmarsat in May 2023. Net loss for the quarter was $124 million, compared to a $47 million loss from continuing operations in the prior year period. The increase in net loss was driven primarily by higher interest expense associated with the additional debt incurred and assumed in the Inmarsat acquisition and non-recurring charges relating to the integration of Inmarsat. Adjusted EBITDA in Q3 FY2024 was $383 million, an increase of 214% compared to Adjusted EBITDA from continuing operations in the prior year period. Our Q3 FY2024 results included a full quarter of contribution from Inmarsat. Including Inmarsat’s results in the prior year period for a more meaningful comparison, YoY revenue and Adjusted EBITDA growth for the combined companies in the quarter would have been 8% and 11%, respectively. Inmarsat’s stand-alone performance for the quarter ended December 31, 2023, was very good, with top line revenue of $443 million, a 12% YoY increase, and estimated Adjusted EBITDA of $260 million, a 17% YoY increase. As a reminder, substantially all of Inmarsat’s former aviation, maritime and enterprise business units are included in our Satellite Services segment, while their former government business unit is included in our Government Systems segment. We ended the quarter with $3.7 billion in backlog after reporting $1.2 billion of awards during the quarter, a 111% YoY increase in awards from continuing operations. Government Systems ended the quarter with over $6.4 billion of IDIQ unawarded potential contract value, an increase of 152% YoY in IDIQ unawarded potential contract value from continuing operations. The growth in awards and the IDIQ portfolio was primarily due to the inclusion of Inmarsat’s awards and IDIQ portfolio in the current year period, plus a significant new satellite services contract from the US government for approximately $260 million. Shareholder Letter | Q3 Fiscal Year 2024

Our results reflect good execution across our diverse set of global mobility markets, including in-flight connectivity (IFC), government, business aviation and enterprise maritime. Evidence of this includes the renewed long-term commitment by Viasat and Deutsche Telekom to the European Aviation Network (EAN), comprised of S-band satellite coverage and a complementary ground network component operated by Deutsche Telekom. Subsequent to quarter end, Lufthansa Group became a new EAN customer by agreeing to equip more than 150 aircraft with our EAN IFC solution. This is in addition to the 240 Lufthansa Group aircraft contracted on our Ka-band network. Our liquidity position at the end of Q3 FY2024 was very strong, at over $2.9 billion, which included $1.65 billion of cash. Sequentially, net leverage3 increased slightly to 3.8x estimated combined LTM Adjusted EBITDA as of Q3 FY2024, a 0.1x sequential increase, and remains substantially favorable to plan at the time the Inmarsat acquisition was announced. The ViaSat-3 F1 satellite continues to undergo testing of the payload and affected antenna. Based on the results of this testing to date we continue to expect to obtain sufficient bandwidth and coverage flexibility, combined with our existing and planned fleet, and partner space resources, to support our growing global mobility business. We currently anticipate placing the satellite into commercial service with our first mobility flights enabled next quarter, Q1 FY2025. During the quarter our antenna supplier completed its root cause investigation of the ViaSat-3 F1 antenna deployment anomaly. Based on its findings and recommendations, we are implementing several corrective actions on the ViaSat-3 F2 antenna. We expect to complete those actions as well as extensive testing and spacecraft integration by early calendar 2025 with launch expected shortly thereafter. The scheduled launch of ViaSat-3 F3 remains on track for late in the fourth quarter of calendar 2024. The F3 satellite has a different antenna design by a different supplier, and its schedule is not affected by the ViaSat-3 F1 anomaly. Finally, our insurance recovery claims are proceeding well with some payments received in Q4 FY2024 and the majority anticipated to be paid in FY2025. With continued growth in our core businesses, realization of strategic, operational and capital synergies consistent with the growth objectives in our core markets, we anticipate YoY growth in revenue and Adjusted EBITDA in Q4 FY2024 and for FY2025, as well as achieving our free cash flow inflection point in the first half of calendar 2025. Additional details are provided in the Outlook section of this letter. Shareholder Letter | Q3 Fiscal Year 2024

Q3 FY2024 Financial Results › Revenue of $1.1 billion in Q3 FY2024 was up 73% compared to revenue from continuing operations of $651 million in Q3 FY2023. Inmarsat’s full quarter contribution was $443 million, a 12% increase YoY from Inmarsat’s standalone revenue in the prior year period › Net loss of $124 million for Q3 FY2024 increased from a net loss from continuing operations of $47 million in the prior year period primarily due to increased interest expense associated with the additional debt incurred and assumed in the Inmarsat acquisition and non-recurring charges relating to the integration of Inmarsat following the acquisition › Adjusted EBITDA for the quarter was $383 million, an increase of 214% YoY relative to Adjusted EBITDA from continuing operations in Q3 FY2023. Inmarsat’s full quarter estimated Adjusted EBITDA contribution was $260 million reflecting YoY growth of about 17% from Inmarsat’s standalone estimated Adjusted EBITDA in the prior year period. Viasat’s results were driven by the Inmarsat acquisition, strong demand for commercial IFC services and strength in our Government Systems segment › Government Systems, excluding Inmarsat’s contribution, had another exceptional quarter with a 24% YoY increase in revenue from continuing operations – primarily from significant demand for information assurance and tactical satcom products › Satellite Services revenue, excluding Inmarsat’s contribution, was flat YoY with growth from commercial air IFC services offsetting fixed broadband subscriber declines as we continue to prioritize bandwidth for mobility services › Awards for the quarter were $1.2 billion, an increase of 111% YoY from awards from continuing operations primarily due to the full quarter contribution from the acquisition of Inmarsat and large Q3 FY2024 government satellite services awards › Net leverage increased sequentially to approximately 3.8x estimated combined LTM Adjusted EBITDA Shareholder Letter | Q3 Fiscal Year 2024 AWARDS $ in million REVENUE $ in millions OPERATING INCOME (LOSS) $ in millions NET INCOME (LOSS)2 $ in millions ADJ. EBITDA1 $ in millions BACKLOG $ in millions

Government Systems Segment Highlights › Supported the U.S. Air Force in a major military exercise called Mobility Guardian 2023. Viasat provided resilient and interoperable airborne communications through its Beyond Line-of-Sight hatch terminal integrated with its next generation Move Out/Jump Off interoperable tactical gateway. Additionally, Viasat used its NetAgility SD-WAN networking router to bridge these networks with Automated Primary, Alternate, Contingency and Emergency capabilities to ensure robust and resilient connectivity › Partnering with Safran Data Systems to bring InRange to market; InRange is a global in-orbit telemetry solution leveraging Viasat’s ELERA L-band network that enables launch providers and spaceports to relay launch vehicle telemetry in flight throughout their trajectory without having to rely on ground networks › Unveiled new portable, flat panel GX LITE Terminal for mobile use by land forces. Built with land expeditionary users’ requirements in mind, GX LITE readily translates to any “grab and go” situation and enables secure, flexible, high-throughput communications worldwide › Integrated our flexible dual-band broadband terminal, the GAT-5530, onto the Airbus C295 MSA aircraft for the Irish Air Corps, which focuses on the Military Air Defence of Ireland airspace and supports United Nations peacekeeping operations Awards Government Systems Q3 FY2024 awards were $584 million, a more than fourfold increase compared to awards from continuing operations in Q3 FY2023. Underscoring the YoY growth was the full quarter impact of high-value, recurring services awards from Inmarsat’s portfolio alongside stronger demand from information assurance products and tactical satcom networks. Q3 FY2024 backlog of $1.2 billion more than doubled compared to backlog from continuing operations of $530 million in Q3 FY2023. Unawarded IDIQ contract value reached $6.4 billion at the end of Q3 FY2024. Revenue In Q3 FY2024, Government Systems revenue increased to $381 million, a 109% YoY increase from Q3 FY2023 revenue from continuing operations. A full quarter impact from Inmarsat enabled service revenue to grow 179% YoY. Product revenue also increased significantly by 55% YoY driven by high-speed network encryption products and tactical satcom products. Q3 FY2024 benefitted from strong demand enabling us to accelerate certain product deliveries. Adjusted EBITDA Q3 FY2024 Adjusted EBITDA grew to $130 million, a 155% YoY increase from Q3 FY2023 Adjusted EBITDA from continuing operations. The full quarter contribution from Inmarsat services and revenue flow through from our Type 1 high-speed network encryption and tactical satcom products were the main drivers for the YoY growth. Adjusted EBITDA margin of 34% was approximately 600 basis points higher compared to Q3 FY2023. Shareholder Letter | Q3 Fiscal Year 2024 AWARDS, REVENUE AND ADJ. EBITDA1 $ in millions BACKLOG AND UNAWARDED IDIQ $ in millions

Satellite Services Segment Highlights › Revenue from aviation, maritime, enterprise and other services rose to 79% of segment total, driven primarily by the full quarter impact from Inmarsat and significant growth in commercial air IFC services › Announced a new, long-term agreement with Deutsche Telekom to provide IFC solutions to airline partners across the European Aviation Network (EAN), which combines S-band satellite coverage with a complementary air-to-ground network › Subsequent to quarter end, Lufthansa Group became a new EAN customer by agreeing to equip more than 150 aircraft with our EAN IFC solution › Launched in partnership with Skylo Technologies, the world’s first global direct-to-device network enabling Mobile Network Operators, device makers and chipset manufacturers to enable their products to seamlessly connect over both terrestrial and satellite networks via 3GPP Release 17 within our global L-band network coverage Revenue Q3 FY2024 Satellite Services revenue increased 92% YoY to $581 million compared to $302 million from Q3 FY2023. The full quarter impact of Inmarsat services and additional aircraft in service from commercial aviation were the key drivers to the YoY growth, partially offset by expected declines in the U.S. fixed broadband business as we continued to prioritize mobility services. Our combined fleet of commercial aviation aircraft ended the quarter at over 3,500 planes in service and continues to be the fastest growing element of our Satellite Services segment. Adjusted EBITDA Satellite Services Q3 FY2024 Adjusted EBITDA more than tripled YoY to $289 million. Adjusted EBITDA growth was a result of the full quarter contribution from Inmarsat, increased commercial aircraft in service, lower advertising expenditures and moderating ground network rollout expenses. The growing proportion of mobility services in our service portfolio, along with a significant portion of those services distributed through indirect channels, and certain favorable one-time services items, resulted in a Q3 FY2024 Adjusted EBITDA margin of 50%, a significant increase compared to an Adjusted EBITDA margin of 30% in Q3 FY2023.

Commercial Networks Segment Highlights › The antenna supplier concluded its ViaSat-3 F1 reflector anomaly investigation with root causes identified and corrective actions developed for application to the ViaSat-3 F2 satellite. We expect the reflectors with supplier corrective actions implemented will be delivered to Boeing in late calendar 2024 with anticipated spacecraft launch in the first half of calendar 2025 › Completed thermal vacuum testing on the second satellite in the upcoming Arctic Satellite Broadband Mission. The two ASBM satellites host Viasat’s GX-10a and GX-10b Ka-band payloads, extending our high-speed global network across the Arctic region including polar coverage. Both satellites are expected to launch together in mid-calendar 2024 › Expect to begin thermal vacuum testing on the ViaSat-3 F3 spacecraft in April 2024 with launch anticipated to occur late in the fourth quarter of calendar 2024 › Submitted insurance claims for Inmarsat-6 F2 and ViaSat-3 F1 for $349 million and $421 million, respectively. The claims process is progressing as expected, with initial payments received subsequent to quarter end Awards In Q3 FY2024, Commercial Networks awards decreased 23% YoY to $113 million due primarily to the timing of orders for commercial air IFC terminals and energy products partially offset by growth from antenna systems. Backlog ended the quarter at $636 million. Revenue Commercial Networks Q3 FY2024 revenue was $166 million, essentially flat YoY. Lower revenue from commercial air IFC terminal deliveries YoY was offset by the full quarter impact from the Inmarsat acquisition. We expect commercial air IFC terminal deliveries to continue to be lumpy quarter to quarter, reflecting the timing of new aircraft deliveries and retrofit cadence by our airline partners. Adjusted EBITDA Q3 FY2024 Commercial Networks Adjusted EBITDA was a $35 million loss, an increased loss compared to the prior year period. Lower gross margins, higher SG&A and higher R&D expenditures were the primary drivers of the increased loss YoY. Shareholder Letter | Q3 Fiscal Year 2024 AWARDS, REVENUE AND ADJ. EBITDA1 $ in millions

Balance Sheet, Cash Flows and Liquidity Operating Cash Flow Viasat generated $134 million in operating cash flow during the quarter, an increase of $44 million YoY and down $85 million sequentially. The YoY comparison reflects the full quarter contribution from Inmarsat and improved operating results, partially offset by increased working capital and decreased operating cash flow associated with the divestiture of the Link-16 TDL business in Q4 FY2023. The sequential decline was primarily related to a combination of cash payments related to our organizational realignment, taxes payable on the gain on the divestiture of the Link-16 TDL business and an Inmarsat tax settlement. Capital Expenditure Q3 FY2024 capital expenditures were $421 million, an increase of 42% YoY. The YoY increase was primarily due to the full quarter contribution from Inmarsat. Excluding Inmarsat’s contribution, capital expenditures were down 3% YoY and up 10% sequentially; this YoY decline was primarily related to lower capital expenditures in general infrastructure spend and customer premise equipment. Sequentially, the increase primarily reflects higher satellite expenditures as ViaSat-3 F2 and F3 near completion. Debt and Leverage Viasat ended Q3 FY2024 with $2.9 billion in available liquidity, which consisted of $1.65 billion in cash and cash equivalents and $1.3 billion of combined borrowing ability under our two undrawn revolving credit facilities. Net debt of the combined companies was $5.9 billion and our net leverage ratio increased sequentially to 3.8x of estimated combined LTM Adjusted EBITDA.

FY2024 Outlook During the quarter, we maintained strong financial performance, took actions to achieve operating cost and capital expenditure synergies, and earned substantial new business awards. Our awards and backlog continued to increase driven by our government and mobility businesses in particular. The Inmarsat integration and organizational transformation, combining the best of each company, continued to make progress, consistent with the accelerated timeline and increased magnitude of synergies that we announced last quarter. As a result, we continue to expect to grow over the near- and long term while improving cash generation. As a reminder, we closed the acquisition of Inmarsat on May 30, 2023. To facilitate comparability, Inmarsat’s financial results are included with Viasat’s on a combined basis in our YoY comparisons below. Outlook for our expected actual results in FY2024 reflect 10 months of Inmarsat contributions only. › For FY2024 we expect YoY revenue growth in the high single-digit percentages over the combined revenue of Viasat and Inmarsat in FY2023, excluding the one-time benefits from the litigation settlement of $56 million in Q2 FY2023 and $95 million in Q2 FY2024. Excluding the non-recurring contribution to revenue from the litigation settlement, Viasat expects FY2024 actual revenue to increase to a range of $4.10 billion to $4.25 billion (which includes 10 months of Inmarsat contributions). › For FY2024 we expect YoY Adjusted EBITDA growth in the mid-single-digit percentages over FY2023 estimated combined Adjusted EBITDA, excluding the one-time benefits from the litigation settlement of $51 million in Q2 FY2023 and $86 million in Q2 FY2024. Excluding the non-recurring contribution to Adjusted EBITDA from the litigation settlement, Viasat now expects FY2024 Adjusted EBITDA to increase to a narrowed range of $1.275 billion to $1.30 billion (which includes 10 months of Inmarsat contributions). › Satellite Services revenue is expected to grow modestly in FY2024 compared to FY2023, supported by growth in mobility offset by an expected decline in U.S. fixed broadband revenue. › Government Systems revenue is expected to deliver strong YoY growth in FY2024, with increasing contributions from sales of encryption products and as government service revenue scales. Government Systems revenue visibility for the remainder of FY2024 is supported by backlog of over $1.2 billion, alongside growing recurring government service revenue contributions from Inmarsat. › Commercial Networks revenue is expected to grow significantly in FY2024 compared to FY2023 with solid contributions from IFC terminal deliveries and advanced ground antenna systems. › Net leverage is expected to increase modestly by the end of FY2024 as cash balances are partially used to fund capital expenditures. We continue to expect to grow revenue and Adjusted EBITDA again in FY2025 relative to FY2024 (including, for comparability, a full 12 months of Inmarsat financial results in FY2024 on a combined basis and excluding the one-time benefit from the litigation settlement mentioned above). Capital expenditures for FY2025 are expected to decline to a range of $1.4 billion to $1.5 billion, excluding the benefit from insurance recoveries. We continue to expect an inflection to positive free cash flow in the first half of calendar year 2025. We have large and growing markets for mobility services to source our growth, a diverse combination of businesses, unique space and ground assets to serve these markets with healthy awards and backlog, and cost reduction actions that support our growth outlook through 2025 and beyond. Sincerely, Mark Dankberg Guru Gowrappan Shareholder Letter | Q3 Fiscal Year 2024

Endnotes 1. A reconciliation of Adjusted EBITDA to net income (loss) attributable to Viasat, Inc. is provided at the end of this letter. For all three segments Adjusted EBITDA includes certain corporate and other indirect costs previously allocated to the discontinued operations that have been reallocated across all three segments for Q3 FY2023. 2. Net income (loss) as used herein is defined as net income (loss) attributable to Viasat, Inc. common stockholders. 3. Net leverage ratio is defined as principal amount of total debt less cash and cash equivalents and short-term investments divided by estimated combined Adjusted EBITDA for the twelve-month period ended December 31, 2023. Estimated combined LTM Adjusted EBITDA is calculated by combining Viasat’s Adjusted EBITDA from continuing operations for the applicable period (which includes Adjusted EBITDA of Inmarsat for periods subsequent to the acquisition) and the estimated Adjusted EBITDA of Inmarsat for periods through the closing of the Inmarsat acquisition (which, for the net leverage ratio is the five months ended May 30, 2023, and for the YoY Adjusted EBITDA growth outlook is the twelve months ended March 31, 2023 (for FY2023) and the two months ended May 30, 2023 (for FY2024)).

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. A reconciliation of specific adjustments to GAAP results is provided in the tables below. In addition, we have included estimations of Adjusted EBITDA of the Inmarsat business for certain periods to enhance investors’ understanding of the contribution of the newly acquired Inmarsat business to Viasat’s overall financial performance. Inmarsat’s stand-alone results of operations are reported in accordance with International Financial Reporting Standards (IFRS) and not GAAP in accordance with the requirements of Inmarsat’s debt instruments. However, to facilitate comparability with statements regarding Viasat’s overall Adjusted EBITDA, these estimations of Inmarsat’s Adjusted EBITDA have been prepared using the same methodology and adjustments as used in the calculation of Viasat’s overall Adjusted EBITDA. However, as IFRS differs from GAAP in a number of important respects, readers are cautioned not to place undue reliance on these estimations, which have been prepared for illustrative purposes only. In addition, for purposes of calculating our net leverage ratio as of December 31, 2023, we use estimated combined LTM Adjusted EBITDA for the twelve months ended December 31, 2023. Moreover, to facilitate comparability of YoY Adjusted EBITDA and revenue, we use estimated combined Adjusted EBITDA for FY2023 and FY2024 and estimated combined revenue and Adjusted EBITDA for Q3 FY2023. Estimated combined Adjusted EBITDA for the twelve months ended December 31, 2023, FY2023 and FY2024 represents Adjusted EBITDA of Viasat and estimated Adjusted EBITDA of Inmarsat (for periods prior to the Inmarsat acquisition) for the applicable twelve-month period on a combined basis, as if the Inmarsat acquisition had occurred on the first day of such period. Similarly, estimated combined revenue and Adjusted EBITDA for Q3 FY2023 represent revenue and Adjusted EBITDA of Viasat and revenue and estimated Adjusted EBITDA of Inmarsat on a combined basis, as if the Inmarsat acquisition had occurred on the first day of the quarter. These presentations do not conform to GAAP or the Securities and Exchange Commission rules for pro forma presentations; however, we have included these combined results solely for purposes of presenting our net leverage ratio as of December 31, 2023, and to facilitate comparability of our results and outlook for revenue and Adjusted EBITDA growth YoY (which otherwise would not provide a comparable presentation). This estimated combined financial information is unaudited and does not include any pro forma adjustments to reflect the Inmarsat acquisition and related transactions. Estimated combined quarterly and LTM Adjusted EBITDA has been prepared by management for illustrative purposes only in connection with our presentation of net leverage ratio and to facilitate comparability of our outlook for Adjusted EBITDA growth YoY and does not purport to be indicative of what the combined company’s results of operations would have been if the Inmarsat acquisition and related transactions had occurred at the beginning of the period presented. In addition, the combined financial information does not reflect non-recurring charges incurred in connection with the Inmarsat acquisition, nor any cost savings and synergies expected to result from the Inmarsat acquisition (and associated costs to achieve such savings or synergies), nor any costs associated with severance or integration activities resulting from the Inmarsat acquisition.
