The Irish Stock Exchange is to undergo a €10 million expansion with the acquisition of a building on Foster Place in Dublin City Centre.

The new building will be incorporated into the existing premises on Anglesea Street to create a single campus headquarters.

The expansion is being carried out to cater for a 50% increase in staff numbers to facilitate the ISE's national and international business.

The ISE has grown staff numbers by 40% to 114 over the last three years in response to increased business volumes and to target new revenue streams.

The businesses of the Irish Stock Exchange now span 80 countries with over 33,000 securities and over 4,100 issuers from multiple sectors listing on its markets.

"Anglesea Street has been home to a stock exchange business for longer than New York's Wall Street," ISE Chief Executive Deirdre Somers said.

"The €10 million investment will allow the ISE to continue to operate from its current building, which was purpose built to house the Exchange over 135 years ago. 

The ISE will be submitting plans for developing the new HQ to Dublin City Council in the coming months.
