MUNICH (Reuters) - Austrian sensor specialist AMS AMS.S is actively buying Osram OSRn.DE shares and currently holds a stake of almost 3% in the German lighting group, its chief executive said on Monday.

AMS launched a 4.3 billion euro ($4.8 billion) takeover bid for Osram earlier this month, beating a rival offer from private equity investors Bain Capital and Carlyle Group CG.O by 10%.

AMS’s Osram shares will be counted toward the minimum acceptance threshold in the takeover process, Alexander Everke said at a news conference in Munich.
