The high-tech US stock exchange Nasdaq has said earnings rose 42% compared to the same time 12 months ago and also raised its income forecast for 2006.
Nasdaq purchased a sizeable chunk of the LSE in April
Earlier in April the Nasdaq bought a 15% stake in the London Stock Exchange (LSE) at a price of £11.75 per share, in a deal worth £447.7m ($780m).
That came a month after it dropped a takeover of the LSE, when a £9.50-a-share proposal was rejected.
Nasdaq first quarter net income was $18m (£10m), up from $12.7m a year ago.
The exchange now says it is looking to incomes of $63m to $73m for the full year, up from the $57m to $69m predicted at the start of the year.
At the time of the LSE buy a Nasdaq spokesman said it had been a "very strategic purchase".
Analysts are now watching to see if it makes a full bid for the London market.
However Nasdaq chief executive Robert Greifeld would only say that it was now "entering a phase of global consolidation in the exchange space" and that it is in a strong position to become a "preferred partner for exchanges all across the planet".
