The Irish Stock Exchange reported a 35% rise in pre-tax profit to €6.3m despite a drop in revenue during 2012.
Revenue was down 4% to €20.4m. The ISE generates two thirds of its business from listing international funds, debt and shares. Revenue from those sources fell 3% to €13.2m.
The higher profit for the year resulted mainly from a €2.6m reduction in operating costs. The ISE said this could mainly be attributed to the renegotiation of "infrastructure contracts" and savings generated as a result of the winding up of its defined benefit pension scheme in 2011.
"The economic environment remains challenging but we dealt with our challenges well during 2012," said ISE chief executive Deirdre Somers.
She said the Stock Exchange was looking to develop "new and innovative sources of income" over the coming year.
