Euronext chief executive Stéphane Boujnah says the exchange operator has plenty of ammunition for further acquisitions after bidding €510 million in cash for the London Stock Exchange Group's French clearing business.

The offer for LCH SA had been expected after it was reported in December that Euronext had entered into exclusive talks to buy the business. The LSE is selling the business in order to remedy anti-trust concerns over its merger with Germany's Deutsche Börse.
