Stockbroking company Dolmen has been taken over US group Cantor FitzGerald.
Under new ownership Dolmen will become a primary dealer in Irish Government bonds, which means it will sell debt international investors.
Cantor plans to hire additional staff in Ireland.
The US company lost two thirds of its New York workforce in the 9/11 attacks on the Twin Towers when 658 staff members died.
Since the attacks Cantor FitzGerald has rebuilt and now has an office in mid town Manhattan.
Last year Dolmen lost €250,000 which is an improvement on its 2010 performance when it lost €1.26m. The company has no borrowings.
