NZX says operating earnings rose 8% to $14.7 million in the nine months to the end of September, compared with the same period a year ago.
Revenue rose 29% to $31.1 million, and NZX's chief executive mark Weldon says that's due to firms raising money through the stock market and the growth of its agriculture business.
Mr Weldon says it's expecting more listings, higher trading and stronger data sales next year.
