Deutsche Börse AG CEO Theodor Weimer said the German stock exchange operator is eyeing acquisitions that complement its growth strategy but is staying away from some mega deals, Reuters reported.

"Transformational transactions, whereby we thereafter no longer hold majority, or our headquarters is no longer in Hesse, are not an option for us," Weimer reportedly said at the company's May 16 annual general meeting.

His statement comes a year after the group's failed merger attempt with London Stock Exchange Group PLC.

Weimer also told shareholders that he plans to cut up to 50 management positions as part of its aim to reduce annual operating costs by €100 million by the end of 2020, Bloomberg News reported.

The CEO reiterated that he expects the group to incur one-off costs of €200 million as a result of that broader cost-cutting drive, most of which will be incurred in 2018.

Weimer added that the group could increase its staff numbers by more than 100 in the coming years if it is able to achieve its targets, including raising revenues from "secular growth opportunities" by 5% annually through 2020 and increasing net income by between 10% and 15% over the same period, Bloomberg noted.
