London Stock Exchange, which is in the process of buying Canada's TMX Group, easily beat analyst forecasts, reporting 2010 profit up 22 per cent to £341.1m.
The British exchange, which also said it has filed its application to merge with Canadian market TMX Group, saw profits well up on last year's £280.3m and above forecasts of £313.6m.
LSE Group Chief Executive Xavier Rolet said the performance was partly down to the diversification strategy the exchange has undertaken.
"We are also fully focussed on pursuing a range of growth opportunities which will remain pivotal to further progress in the year ahead," Rolet said in an emailed statement.
Revenues increased seven per cent to £674.9m, up on last year's 628.3m, and above analyst expectations of £651.1m
The LSE dividend for the period was 26.8p per share, above forecasts of 25.9p a share.
The British exchange agreed a merger with TMX group on 9 February and said it has filed its application with the relevant Canadian authorities.
