Explanation of Responses:

1. This entry represents the number of shares of Viasat, Inc. common stock withheld by the Issuer to satisfy the tax withholding obligation of the Reporting Person. These shares were not sold by the Reporting Person but were instead offset from the total number of vested shares received by the Reporting Person from the Issuer.

2. The original restricted stock unit grant was for 18,678 restricted stock units on 11/17/2021. Subject to the Reporting Person's election to defer the receipt of common stock, the units vest and convert into shares of common stock of the Issuer over a four year period commencing on 12/17/2022 and ending on 11/17/2025.

3. Until vested, the restricted stock unit shall be subject to forfeiture in the event of termination of employment or service with the Issuer.

4. On November 17, 2021 the reporting person was granted an award of performance-based stock options, which vested based upon the Issuer's total shareholder return ("TSR") relative to the TSRs of the Issuer's peer companies over a four-year performance period (the "Relative TSR"). On November 18, 2025, the Compensation and Human Resources Committee of the Issuer's Board of Directors certified the Issuer's Relative TSR performance, resulting in the vesting of this award.

5. The stock option is fully vested and currently exercisable.
