The company said the second quarter was its most profitable since it went public, despite a fall in trading volumes ahead of Britain's vote to leave the European Union.

Euronext said in mid-June it would take special measures in anticipation of higher volatility and trading volumes expected in the run-up to and following the referendum in Britain on its membership of the European Union.

The bourses operator, which set a target of 5 percent revenue growth up to 2019, said cost-cutting would be a key factor in its growth strategy during this period.

Euronext, which operates bourses in Paris, Amsterdam, Brussels, London and Lisbon, said operating profit before exceptional items rose to 73.9 million euros (62.05 million pounds) in the quarter ended June 30, from 65.6 million euros a year earlier.

The company said revenue from cash trading fell 6.6 percent while revenue from derivatives trading was down 7.6 percent in the quarter.

Third party revenue rose 1.7 percent to 132.3 million euros (111.08 million pounds) in the quarter.
