Board Update

Shearwater Group plc, the cybersecurity, advisory and managed security services group, announces that David Williams will step down as Chair of the Company with effect from 31 January 2026 following over a decade with the Company.

Robin Southwell OBE, current Independent Non-Executive Director has been appointed as Chair and will assume the role from that date.

Robin joined Shearwater in October 2016 as a Non-Executive Director. With forty years' experience in the aerospace and defence industry, his roles have included Chief Executive Officer of Airbus UK and Airtanker Ltd, as well as senior positions at BAE Systems. Robin was a DTI Business Ambassador for the UK Government and received his OBE in 1997. The Board is delighted he has agreed to take on the role of Chair.

Following his appointment as Chair, Robin will also assume the role of Chair of both the Remuneration Committee and the Nomination Committee, previously chaired by David.

David Williams, outgoing Chair, commented: "The focus of these past few years has been on rebuilding the business organically, and I am delighted that this has now been achieved, as demonstrated by the more positive FY25 results. Following ten years as Chair, and with the Group in a stronger position, this marks a natural time for me to step down. I have no doubt that the Company is well placed to succeed, supported by a strong management team, a robust balance sheet and a healthy pipeline of opportunities."

Robin Southwell OBE, incoming Chair, commented: "The Board would like to express its gratitude to David for his dedication over the last ten years and thank him for his valued leadership and guidance. I am looking forward to taking on the role as Chair and continuing to support the Group at what is an exciting time for the business."
