She is leaving to pursue a portfolio of non-executive directorships, but will remain in post for the next few months to allow a smooth transition.

“Fiona has been instrumental in transforming the exchange since she joined as CEO just over five years ago,” said Chairman of The International Stock Exchange Group, Jon Moulton. “In that time, we have seen consistent growth both in the number of listings on the exchange and the profitability of the company, which is illustrated by the company’s market value rising tenfold in that period.

“We wish her well in the future and thank her for her productive efforts. The board has now started a search for a new CEO to continue the development and growth of the business.”

Mrs Le Poidevin took up the role in January 2015 – shortly before the company opened its office in Jersey and listed on TISE.

Since that time, the group has opened an office in the Isle of Man and rebranded to reflect both the geographical expansion and the international nature of the client base.

There are currently about 3,000 listed securities on TISE with a total market value of more than £350billion

“I have thoroughly enjoyed my time at TISE in what has been a very challenging and rewarding role,” Mrs Le Poidevin said. “I am extremely proud of what we have achieved as a team during the last five years. We have not only transformed the business and facilitated significant growth, but we have also created a new brand that is we;; recognised and respected in the marketplace and which we have been promoting across the globe, including in the US and Asia.

“In addition, we have created opportunities for our people, increasing our staff numbers overall by more than 50% and fostering a positive culture which reflects core values.”

Before joining the exchange, Mrs Le Poidevin was Chief Executive of Guernsey Finance. Previously a Senior Tax Manager with a ‘big four’ accountancy firm, she has more than 20 years’ experience working in financial services in both London and the Channel Islands.
