Gamma Communications plc

("Gamma" or the "Company")

Board change

Gamma, a leading technology-based provider of communications services to the business markets in the UK and Europe, announces that Martin Lea has informed the Board that, as he approaches the end of his ninth year on the Board, he will be standing down from his role as an Independent Non-Executive Director at the conclusion of the next Annual General Meeting ("AGM"), to be held on Tuesday 17 May 2023. Martin will also cease to be Chair of the ESG and Risk Committees, and a member of the Remuneration and Nomination Committees, on the same date.

Martin Lea has supported Gamma, its Board and executive management team substantially from being a private company, through IPO, to the company it is today and has contributed significantly to the development and execution of the Group's long-term planning. Martin's knowledge of the telecommunications sector has been invaluable through the execution of our growth strategy.

Richard Last, Gamma's Chairman, commented:

"On behalf of the Gamma Board, I would like to express our thanks to Martin for his substantial support, particularly during the IPO in 2014 and in the years that followed. Martin's role as our Senior Independent Director, along with chairing the Remuneration, Risk and ESG committees over the years, has served the company and its shareholders exceedingly well. We have benefitted from his broad experience and counsel, and his dedication and expertise will be missed. We wish him the very best for the future."

Notes:

1)   Shaun Gregory will assume the role of Chair of the ESG Committee on Martin's retirement.

2)   Rachel Addison will assume the role of Chair of the Risk Committee on Martin's retirement.
