She will continue to work as CEO of the company with the full support of Amey’s parent company Ferrovial and the new owners, Buckthorn/One Equity Partners, to guide the transition over the coming weeks.

Ferrovial’s CEO of Energy Infrastructure and Mobility, Gonzalo Nieto, said: “We would like to thank Amanda for her excellent work as she prepares to step down as Chief Executive.

“During her three-year tenure she has overseen a cultural transformation, making Amey a modern organisation which puts its people first, and has successfully prepared the business for its sale.”

Chairman of Amey, Ian Tyler, added: “Amanda has strengthened Amey’s role as a strategic partner to government, not only in delivering services used by millions every day, but also in creating jobs, skills and social value for communities across the UK. We wish her well in her future endeavours.”

Nicholas Gee, Founding Partner of Buckthorn said: “We fully recognise Amanda’s contribution to the business and all she has achieved during her tenure as CEO. We look forward to working with her as we effect the transition to our ownership.”

Ferrovial announced in October that it was selling Amey for £400m to a company controlled by funds managed by One Equity Partners and Buckthorn.

Final completion of the deal is subject to regulatory clearances and is expected to take place by the end of this year.
