Power of Attorney for Section 16 Reporting Person

This filing documents a Power of Attorney granted by Thad Trent, a Section 16 reporting person of Lumentum Holdings Inc., to Wajid Ali, Jae Kim, and Jonathan Shanberge. This authorization allows the appointees to execute and file Forms 3, 4, and 5, along with any necessary amendments, on behalf of Mr. Trent. These actions are required due to his ownership, acquisition, or disposition of the Company's securities, as mandated by Section 16 of the Exchange Act. The attorneys-in-fact are also empowered to obtain information regarding transactions in the Company's securities from third parties and to file such forms with the SEC and other relevant entities. The Power of Attorney remains effective until Mr. Trent is no longer required to file these forms, unless revoked earlier in writing. The filing clarifies that neither the attorneys-in-fact nor the Company assume Mr. Trent's compliance responsibilities under the Exchange Act.
