Indivior updates Board Succession Plans

Indivior PLC (the "Company") (LSE: INDV) today announces details of updates to its Board succession plan.

In March 2021, the Board announced details of a comprehensive succession plan, which was designed to fully align and support Indivior's key strategic priorities.  A key part of this succession plan was the appointment of additional Non-Executive Directors to broaden and strengthen the Board's skills and expertise and to position Indivior for long-term sustainable growth.  Over the course of the past twenty months, an additional five Non-Executive Directors have been appointed to the Board; these appointments have further enhanced the skills, experience and diversity of the Board.

Lorna Parker, Daniel J. Phelan and Tom McLellan joined the Board at its inception in November 2014 and will all reach the end of their nine-year terms of office in 2023.  To ensure a smooth transition Lorna Parker, Non-Executive Director, and Daniel J. Phelan, Senior Independent Director and Chair of the Remuneration Committee, have agreed to remain as Non-Executive Directors until September 30, 2023.

The Board, supported by the Nomination & Governance Committee, is in the process of identifying the successor(s) for the roles of Senior Independent Director and Chair of the Remuneration Committee and an announcement in relation to the successor(s) for these roles will be made in due course.

Given Dr. McLellan's specific skill set and extensive background in addiction sciences, the Board has started a process to replace this expertise on the Board.   Dr McLellan will continue to serve as a Non-Executive Director until a replacement has been appointed and a period of transition has been completed.

Graham Hetherington, Chair, said: 'We have added significant additional skills and experience to the Board over the last two years.  This is critical to positioning Indivior for its next phase and for delivering long-term sustainable growth.  We are grateful to Lorna, Dan and Tom for their continued commitment to supporting the Board through this key transition period and for ensuring smooth continuity.'
