AB Dynamics has appointed Sarah Matthews-DeMers as its next CEO.

Matthews-DeMers, who currently serves as CFO, succeeds James Routh, who will remain with the business until the end of the year to ensure a smooth transition.

Routh will then leave to lead fellow listed firm Victrex at the start of 2026.

The new CEO is said to have played a key role in transforming the automotive testing and simulation group over the past six years.

A Fellow of the Institute of Chartered Accountants in England & Wales, she previously held senior finance and strategy roles at Avon Rubber, Rotork and Carclo, following 14 years at PwC.
