Change of Non-Executive Directors

ITM Power is pleased to announce the appointment of two new Non-Executive Directors, Sir Warren East and John Howarth, effective following the Annual General Meeting (AGM) on 8 October 2025.

Warren brings a wealth of global leadership experience from technology and engineering sectors. He spent 30 years in the semiconductor industry, serving as CEO of ARM from 2001 to 2013. He was appointed CEO at Rolls-Royce in 2015 with a mission to modernise the company, and stepped down from his role at the end of 2022. He has served on the boards of several major engineering and technology companies, including BT, Dyson and Micron. Currently, he serves as a Non-Executive Director at ASML NV and Tokamak Energy Ltd., and is the Chair of NATS, as well as the President of the IET. Warren was awarded a CBE in 2014 and a knighthood in 2025.

John is a Chartered Accountant with deep expertise in manufacturing, renewable energy, professional services and aerospace. He is currently a Partner at S&W LLP, where he provides audit and accounting advisory services to a range of listed and private companies. His previous roles include Partner at EY LLP and senior finance roles at Future plc and PwC LLP. Since 2023 S&W LLP have provided accounting advisory services to ITM Power, with John being the lead engagement partner. Following the conclusion of ITM Power's 2025 full-year audit, John will step down from this role and cease any further involvement with ITM Power in that capacity.

Warren will be a member of the Audit and Remuneration Committee; John will join the Audit Committee and take on the role of Chair of the Remuneration Committee.

After serving as a Non-Executive Director since July 2022, Denise Cockrem will step down from the Board at the time of the AGM.

Sir Roger Bone, Chair of the Board, said, "We are delighted to welcome Warren and John as Non-Executive Directors. Their expertise and insight align well with ITM's strategic growth ambitions. I would like to express my sincere thanks to Denise for her dedication and important contributions to ITM over the past three years. Denise substantially enriched our Board discussions with her calm and sharp intellect. We wish her every success for the future - professionally and personally."
