Board Change and Committee Composition

Gamma, a leading technology-based provider of communication services across Europe, announces that Henrietta Marsh has informed the Board that she intends to retire and will therefore not stand for re-election at the Company's next Annual General Meeting ("AGM"), to be held on Tuesday 21 May 2024. Henrietta will cease to be the Senior Independent Non-Executive Director, Chair of the Remuneration Committee, and a member of the Nomination, Audit and ESG Committees, from the conclusion of the AGM.

Henrietta has made a significant contribution to the Board during her five-year tenure, providing thoughtful and considered guidance and support to drive growth. Her insights from the fund manager community helped us to focus our approach and she contributed significantly to the development and execution of the Group's long-term planning and growth strategy.

Martin Hellawell, Gamma's Chairman, commented:

In the short time I have worked with Henrietta I have found her to be an outstanding board member and I have thoroughly enjoyed working with her. Her expertise in board and public company matters, her thoroughness, tenacity, diligence and commitment are first rate. On behalf of the Board, I would like to thank Henrietta for her dedication and contributions and wish her all the very best for the future.

Committee Composition and Senior Independent Director

Following Henrietta's retirement at the 2024 AGM, the Nomination Committee has recommended, and the Board has approved, the appointment of Rachel Addison as the Senior Independent Director with effect from the close of the 2024 AGM.

It also approved changes to the composition of the Board's committees, as set out below. This includes merging the Audit & Risk Committees to provide combined oversight of these key areas.
