UK software group Scisys has today listed on Euronext's Enterprise Securities Market in Dublin.
Scisys develops information and communications technology services, e-business, web and mobile applications, editorial newsroom solutions and advanced technology solutions.
Last month the company said it was is moving to Ireland so it can participate in EU-funded work such as the European Space Agency's programme after Brexit.
It is one of many companies which have moved to Ireland or opened a base here ahead of Britain's departure from the European Union next March with lawyers, financial firms and industrial groups needing to maintain ties with the bloc.
Ssisys, founded in 1980, operates in the space industry, including work for the European satellite navigation system Galileo.
It also supplies customised software systems and services to the media, space, government and defence sectors.
Mike Love, the company's non-executive chairman, said the admission to trading of Scisys in Dublin is the final step in its Brexit contingency planning to ensure that its business can continue its long-standing participation in both the UK and European markets.
"By complementing our UK listing with a European one on Euronext we will also have continued access to sterling and euro pools of capital in a post Brexit environment," Mr Love said.
Euronext said that since 2014, almost 100 tech companies have gone public on Euronext markets, including Dublin.
