Board Changes

System1 Group plc (AIM: SYS1) today announces that after nine years' service as a non-executive director, Robert Brand, Senior Independent Director, has informed the Board that he will not be seeking re-election at the Annual General Meeting later this year. At that time, Sophie Tomkins, non- executive director and Chair of the Audit Committee will be appointed Senior Independent Director of System1 Group.

The Company has today appointed Rupert Howell to the board of directors of the Company as a non-executive director with immediate effect.

Rupert has an extensive career of around 40 years in the advertising and media sector. He was the co-founder of Howell Henry Chaldecott Lury, a UK-based advertising agency, where he worked from 1987 until 1997 when it was acquired by Chime Communications plc, where he was Chief Executive Officer from 1997 to 2002. He held a number of roles at McCann Erickson from 2003 to 2007, including President of EMEA, Chairman of the UK & Ireland Group and Regional Director of EMEA Operations. He was Managing Director of the Broadcast and Online division and a board director of ITV plc from 2007 to 2010. Following a two year sabbatical, he joined Trinity Mirror plc (now Reach plc) as group development director, and was at Trinity Mirror from 2013 to 2020. He was also a non-executive director of the LSE-listed Matomy Media Limited from 2014 to 2017. He left Reach to focus on his portfolio career. He is chairman of Roxi, the music streaming service, pinwheel, a green energy and sustainable living app start-up and is chairman of the advisory board of Empresa Cura Medicinal, LDA.

Graham Blashill, Chairman of System1 commented: "I should like to thank Robert for his outstanding contribution to System1 over a period of considerable change to our company. His strong support and wise counsel as our Senior Independent Director will be greatly missed. In succeeding him later this year, I know that Sophie Tomkins will make an admirable SID and I look forward to working closely with her. I should also like to welcome Rupert Howell to the Board. Following an illustrious career in the advertising industry I am confident his knowledge and insight will contribute significantly to our future development."
