The International Stock Exchange (TISE) has announced Charlie Geffen as the new Chairman of its regulatory arm, The International Stock Exchange Authority Limited (TISEA).

Mr Geffen was appointed to the Board of TISEA on 1 January 2020 and he will combine this role with his existing business interests. He was previously at the law firm Ashurst for 32 years and latterly, at the US law firm Gibson, Dunn & Cutcher.

Jon Moulton, Chairman of TISEA’s parent company, The International Stock Exchange Group Limited (TISEG), said: “I am delighted to announce Charlie as the Chairman of TISEA. He has significant legal experience across a range of different facets of the corporate environment and he has demonstrated strong leadership during his time in senior positions at two major international law firms. We are looking forward to Charlie bringing this expertise to the Board of TISEA.”

After a law degree at Leicester, Mr Geffen joined Ashurst and spent 32 years there, the last five as the firm’s Senior Partner. This period included the merger with an Australian law firm and growth across continental Europe, Asia and the US.

He then joined Gibson, Dunn & Cutcher and, as Chair of the Corporate Practice in London, led the growth of its Transactional Practice there which secured a number of high-profile M&A mandates.

Mr Geffen has now stepped back from partnership to a senior adviser role at Gibson Dunn. He is also a trustee of the Institute of Cancer Research and a member of Council at Surrey University.

Mr Geffen said: “I am extremely pleased to be taking up the position of Chairman of TISEA. The company has a hugely important regulatory role to play in ensuring an appropriate environment for listing and trading on the Exchange. I am looking forward to leading the team and working with my fellow Board members, our executive, our members and all our other stakeholders.”

Mr Geffen replaces Mark Tubby who has stepped down as Chairman of TISEA after six years in the role.

Mr Moulton added: “I would like to thank Mark for his work as Chairman of TISEA. He has played an important part in the establishment and development of the regulatory arm of the Exchange during his last six years in the role and we wish him well for the future.”

The TISEA Board now comprises Mr Geffen, Adrienne Muir (also non-Executive Director), as well as Executive Directors Mark Nicol (Managing Director), Jonathan Richards and Robbie Andrade.
