Private equity firms Bain Capital and Carlyle Group are weighing a joint bid for Germany’s Osram Licht, Bloomberg reported on Wednesday.
Bloomberg, which cited unnamed people familiar with the matter, said the two firms were conducting due diligence on Osram and could bid by the end of March but might also decide against a formal offer, Bloomberg reported.
Osram, Bain and Carlyle declined to comment.
Shares in Osram were up 11.9 percent at 1205 GMT.
Osram, with a market value of around 3.4 billion euros ($3.85 billion), has been the subject of speculation that it could be a buyout target. The German lighting group, once part of Siemens, sells its products mainly to car manufacturers.
Bloomberg reported in November that Bain was exploring a bid. In December, the Financial Times reported that Carlyle was a potential bidder.
