The OSRAM acquisition just got a whole lot more interesting. On August 11, AMS AG, an Austrian company specializing in sensors for iPhones, submitted a fully financed proposal to OSRAM Licht AG for an all-cash takeover offer for 100% of the share capital of OSRAM at a price of €38.50 per share, 10% above the July offer made by Bain Capital and The Carlyle Group. This is an offer totaling about $4.1 billion.
