German stock market operator Deutsche Boerse said earnings were hit last year by the "challenging market environment".
Deutsche Boerse said in a statement late Tuesday that group net profit fell by 24.6 percent to 645 million euros ($866 million).
Net revenues were down 8.9 percent at 1.932 billion euros and operating profit, as measured by earnings before interest and tax (EBIT), fell by 16.6 percent to 969.4 million euros.
In the fourth quarter alone, net profit rose by 9.4 percent to 165.4 million euros, while operating profit declined by 19.8 percent to 185.2 million euros on a 12-percent decline in revenues to 447.7 million euros.
Deutsche Boerse said it would propose a dividend of 2.10 euros per share for 2012, down from 2.30 euros per share the previous year.
