DIRECTOR DECLARATION

Richmond, VA, and Slough, UK, November 15, 2024 - The Board of Directors of Indivior PLC (Nasdaq/LSE: INDV) have agreed that Jerome Lande will continue to serve as a Non-Executive Director until December 31, 2024, whereupon he will step down from the Board.

The Company's relationship agreement with Scopia Capital Management LP ("Scopia"), otherwise due to expire on December 31, 2024, has terminated in accordance with its terms because the aggregate of Scopia's and its affiliates' interests in the issued share capital of the Company has reduced below the threshold for automatic termination. Notwithstanding that the threshold for automatic termination has been crossed, the Board and Scopia have agreed that Jerome Lande will continue to serve as a Non-Executive Director until December 31, 2024.

The Board would like to express its sincere thanks to Jerome for his significant contribution to Indivior since joining the Board in 2021.
