OMX, whose board has recommended a takeover offer from Borse Dubai, reported on Thursday a drop in fourth-quarter operating profits to 255 million Swedish crowns ($39.96 million; Dh145.9 million).
That compared with 320 million crowns ($50.39 million; Dh183.92 million) in the third quarter and 355 million crowns ($55.9 million; Dh204.03 million) in the year-earlier period.
OMX said its board did not propose a dividend.
Borse Dubai has teamed up with US exchange Nasdaq to buy the Nordic exchange owner for 265 crowns ($41.72; Dh152.28) per share, after which it would transfer OMX to Nasdaq in exchange for a stake in the combined group.
Regulators have approved the deal and the OMX board this month backed it, although the Swedish government has not given final sign-off. Government advisers last week said a Borse Dubai acquisition would be beneficial to the Swedish marketplace.
