Power of Attorney for VIASAT INC

This filing discloses a Power of Attorney granted by Jinhy Yoon, a director of VIASAT INC, to Stacy Nguyen, Barbara Olson, Brett Church, and Paul Castor. The attorneys-in-fact are authorized to execute and submit necessary documents to the SEC for electronic filings, including Forms 3, 4, 5, Schedules 13D and 13G, and Forms 144, related to VIASAT INC securities. They can also obtain information on transactions from third parties and take any action deemed beneficial or legally required. The document clarifies that the attorneys-in-fact are not liable for Yoon's compliance with Section 16 of the Exchange Act or Rule 144, nor does it relieve Yoon of their reporting responsibilities. The Power of Attorney remains in effect until Yoon is no longer required to file these forms, or until earlier revoked. This Power of Attorney revokes all previous powers of attorney regarding the same subject matter.
