Report of Independent Registered Public Accounting Firm

To the Plan Administrator and Plan Participants of

Viasat, Inc. 401(k) Profit Sharing Plan:

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Viasat, Inc. 401(k) Profit Sharing Plan (the "Plan") as of March 31, 2026 and 2025, and the related statement of changes in net assets available for benefits for the fiscal year ended March 31, 2026 and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the net assets available for the benefits of the Plan as of March 31, 2026 and 2025, and the changes in net assets available for benefits for the fiscal year ended March 31, 2026, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying schedule of assets (held at end of year) as of March 31, 2026 has been subjected to audit procedures performed in conjunction with the audit of the Plan's financial statements. The supplemental information is the responsibility of the Plan's management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information in the accompanying schedule, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor's Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

Vesting

Participants are immediately vested in their voluntary contributions, plus actual earnings thereon. Participants are vested in Company matching and profit-sharing contributions as follows:

Additionally, participants become 100% vested in Company contributions upon death, disability, or upon reaching the early or normal retirement ages as defined in the Plan document.

Forfeitures

Amounts forfeited by terminated employees are used to pay expenses of the Plan and/or reduce Company matching contributions. As of March 31, 2026 and 2025, total plan level forfeitures were $700,962 and $521,844, respectively. During fiscal years 2026 and 2025, forfeitures of $200,000 and $250,000, respectively, were utilized to reduce the employer contributions receivable.

Hardship Withdrawals

Upon certain conditions, participants, while still employed by the Company, are permitted to withdraw, in a single sum, a portion of their vested account as a result of an immediate and heavy financial need. These conditions include unreimbursed medical expenses, the purchase of the participant's principal residence, the payment of post-secondary education tuition, the payment of burial or funeral costs of immediate family members, the payment of natural disaster clean-up on the participant's principal residence or to prevent eviction or foreclosure from the participant's principal residence.

Plan Termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of a Plan termination, participants become 100% vested in their accounts.

3. Fair Value Measurements

ASC 820 establishes a framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy under ASC 820 are described below:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 - Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in inactive markets, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value (these are often based on internal models and there is rarely a two-way market).

The asset's fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs.

Investments held in the Plan primarily consist of mutual funds, common/collective trusts, pooled separate accounts, the Company's common stock and self-directed brokerage accounts. These assets are recorded at fair value on a recurring basis. Certain investments are measured at fair value using the net asset value ("NAV") per share (or its equivalent) as a practical expedient. These investments include common/collective trusts and pooled separate accounts, which are typically valued using the NAV provided by the issuer of the fund. The NAV is based on the value of the underlying assets owned by the fund, minus liabilities and divided by the number of shares or units outstanding. The following is a description of the valuation methodologies used for investments measured at fair value. There were no changes in the methodologies used as of March 31, 2026 and 2025.

Mutual funds: Valued at the closing NAV reported on the last business day of the fiscal year, which is also the quoted market prices available on an active market.

Common/collective trusts: Valued by the issuer of the common/collective trust funds based on the NAV of its underlying investments. The underlying investments are valued by the issuer using quoted market prices on active markets and provide for daily redemptions with one or two days' notice.

As of March 31, 2026 and 2025, the Plan's investments in common/collective trusts had no unfunded commitments.

Pooled separate accounts: Valued by the issuer of the pooled separate accounts based on the NAV of the underlying investments. The NAV is not a publicly quoted price in an active market and is determined based upon the fair value of the underlying investments. The pooled separate accounts have no unfunded commitment and redemption restrictions as participant transactions may occur daily.

Company common stock: Investments in securities (common stock) traded on a national securities exchange are valued at the last reported sales price on the last business day of the fiscal year.

Self-directed brokerage accounts: The self-directed brokerage accounts are valued based on the fair value of the underlying investments. The underlying investments are carried at fair value based on quoted market prices.

The preceding methods described may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, although the Plan administrator believes these valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

For fiscal years ended March 31, 2026 and 2025, there were no transfers in or out of Level 3.
