Exchange operator NYSE Euronext on Thursday posted a 19% rise in first-quarter net profit and said planning for its agreed tie-up with Deutsche Börse is on track.

NYSE Euronext's first-quarter net profit was $155m, up from $130m a year earlier, and earnings per share rose to $0.68 from $0.54 previously. Net revenue rose 5% to $679m from $645m due to a better performance from its three key business segments-cash trading and listings, derivatives and information services. The company also declared a cash dividend of $0.30 a share for the second quarter, matching the dividend announced for the first quarter.
