Surface Transforms, the troubled Knowsley-based maker of disc brakes for supercars, announced that chief financial officer Isabelle Maddock “has informed the board of her intention to retire effective 30 June 2025.”

Steven Harrison will join Surface Transforms as interim chief financial officer on March 17.

Shares of Surface Transforms have fallen 97% during the past year as it continued to struggle with capacity constraints and manufacturing. Its stock market market has fallen to just £3.6 million.

The firm said: “To facilitate a successful handover and continuity, the Board is pleased to announce the appointment of Steven Harrison as Interim Chief Financial Officer (non-PLC board), effective 17 March 2025.

“Steven is a seasoned finance professional with over 20 years in CFO roles based in the UK and Internationally and has a broad range of business experience including IPOs, M&A, public and private companies as well as situations with challenging business environments.

“Steven joins Surface Transforms from Aurorium, a PE backed global manufacturer of speciality chemicals where he was interim European CFO, prior to which he was CFO at Saietta Group plc.

Maddock said: “It has been a privilege to serve as CFO of Surface Transforms, but now is the right time for me to focus on starting a new phase of my life.”
