Nasdaq, which runs U.S. and Nordic markets, earned $93 million, or 53 cents per share in the second quarter, up from $92 million, or 51 cents per share, a year earlier.
Excluding one-time items including impairment and restructuring charges, it earned 64 cents a share, compared with 62 cents in the year-ago quarter.
Analysts on average expected the New York-based company to earn 60 cents per share, excluding items, according to Thomson Reuters I/B/E/S.
"This performance was a direct result of our continued focus on cost management, and the execution of our strategy to build strong, recurring and subscription-based revenue businesses that can drive growth, despite the trading environment," Robert Greifled, Nasdaq's chief executive, said in a statement.
Nasdaq said on Friday it plans to pay out $62 million in cash to firms that lost money in Facebook Inc's glitch-ridden initial public offering on May 18, modifying an earlier plan that drew intense criticism from market makers and other exchanges.
Net revenue at the New York-based company was $424 million, versus $415 million a year earlier. Analysts had expected $407.2 million.
The company's global market data products had an 8 percent uptick in revenue to $90 million.
U.S. cash equity trading revenue fell to $373 million from $387 million.
Operating expenses were $249 million, compared with $257 million in the second quarter of 2011.
